Description

Technical Field

[0001] The utility model relates to the technical field of feeding, in particular to a multi-station turntable feeding machine. Background Art

[0002] Before stamping, the surface of the stamping parts needs to be oiled to reduce the friction between the stamping parts and the stamping die, and to cool the die and extend the service life of the die. In addition, oiling the surface of the stamping parts can prevent rust.

[0003] In order to improve production efficiency, the publication number "CN208131847U" and the name "A stamping parts automatic feeding and oiling integrated machine" discloses a stamping parts automatic feeding and oiling integrated machine, which includes the following components: a feeding device, including a multi-station material tray with equal divisions, a lifting mechanism for transporting the stamping parts placed on the material tray up and down, a material taking mechanism for extracting the stamping parts from the material tray, and a conveying mechanism for receiving the stamping parts extracted by the material taking mechanism, the material taking mechanism includes a first weight sensor for detecting the weight of the extracted stamping parts, and the conveying mechanism includes a thickness sensing device for detecting the thickness of the stamping parts; an oiling device, which is arranged behind the conveying mechanism along the conveying direction of the stamping parts, and oils the stamping parts; a control device, including a control system connected to the feeding device and the oiling device through electrical signals, and a controller for collecting information fed back by the control system. The purpose of multi-station automatic feeding is achieved. However, each time the picking mechanism picks up a stamping part, the lifting mechanism needs to lift the entire material tray by the thickness of a stamping part, which makes the lifting mechanism heavily loaded. Moreover, after one of the stations is loaded, the picking mechanism needs to wait for a certain period of time before it can work. Specifically, it needs to wait for the lifting mechanism to descend to the lowest height, and then the material tray rotates to make another station rotate to the loading position, and then the lifting mechanism lifts it to the loading height. Only then can the picking mechanism work, which affects the loading efficiency. Utility Model Content

[0024] For example, see Figures 1 to 7 The present embodiment provides a multi-station turntable loader, which includes a frame 1, a rotating material tray 2, an infeed conveyor belt 3, an outfeed conveyor belt 4, a double-sided oiling mechanism 5, a material ejecting device 6, a temporary storage and supporting device 7 and a loading robot 8.

[0025] The frame 1 includes an adjacent high frame 11 and a low frame 12, and the feed conveyor belt 3, the double-sided oiling mechanism 5 and the delivery conveyor belt 4 are arranged in sequence on the high frame 11. Preferably, the feed conveyor belt 3, the double-sided oiling mechanism 5 and the delivery conveyor belt 4 are all arranged on the same base 13, and an electronic scale is provided between the high frame 11 and the base 13 for measuring the weight of the stamping parts. The stamping parts are in the form of thin sheets, and it is easy for them to be adsorbed after being stacked. If the loading robot 8 puts two sheets of stamping parts that are stacked and adsorbed on the feed conveyor belt 3, the weight will exceed the weight of one sheet of stamping parts, that is, the weight value measured by the electronic scale exceeds the preset weight value, which will be fed back to the controller, and the controller will shut down and alarm.

[0026] The rotating material tray 2 is arranged on the low frame 12, and a plurality of station shelves 21 are arranged on the rotating material tray 2. In this embodiment, the number of the station shelves 21 is four, which are symmetrically arranged on the rotating material tray 2 in a circle center. The rotating material tray 2 is provided with a feed opening 22 at the center position corresponding to the station shelf 21, so that the feed ejection device 6 can push the stamping parts in the station shelf 21. In other embodiments, the number of the station shelves 21 can also be three or more.

[0027] The temporary storage support device 7 is arranged on the elevated frame 11 at a position corresponding to one side of the feeding conveyor belt 3. The temporary storage support device 7 comprises a support 71 and a plurality of supporting components 72. The support 71 is provided with a loading port 73 whose outer dimensions are larger than the station bin frame 21. The plurality of supporting components 72 are symmetrically arranged at the edge of the loading port 73 in a circle center, and are evenly distributed, so as to achieve a good supporting effect. In this embodiment, the number of the supporting components 72 is three, and the supporting components 72 include a fixed plate 721, a vertical rod 722 and a flip hook 723. The fixed plate 721 is arranged at the edge of the feeding port 73, and the vertical rod 722 is vertically arranged at one end of the fixed plate 721. The lower end of the vertical rod 722 is provided with a mounting position 724 for installing the flip hook 723. The tail of the flip hook 723 is arranged in the mounting position 724 through a rotating shaft 725. The flip hook 723 corresponds to the inner wall position of the mounting position 724. A rounded corner avoidance portion is provided at the top corner of the tail of the flip hook 723 to allow it to flip up freely, and a raised blocking portion is provided at the bottom corner of the tail to limit its downward flipping. When the top plate pushes the stamping part, it can push the overturn hook 723 to flip up. After the stamping part rises and passes over the overturn hook 723, the overturn hook 723 automatically flips down under the action of its front gravity. When the overturn hook 723 and the vertical rod 722 are at 90 degrees, the raised blocking part just presses on the inner wall of the installation position 724 to position the overturn hook 723. When the top plate is pressed down, the overturn hook 723 can support and store the stamping part.

[0028] The ejection device 6 is arranged at the lower position of the rotating material tray 2 corresponding to the position of the temporary storage supporting device 7, and can push the stamping parts in the work station shelf 21 located above it to the position of the temporary storage supporting device 7. The ejection device 6 includes an ejection cylinder 61 and an ejection plate 62. The ejection cylinder 61 is vertically arranged in the low frame 12, and its piston rod faces, and the ejection plate 62 is arranged on the piston rod of the ejection cylinder 61. The piston rod directly drives the ejection plate 62, which reduces the transmission components, improves the response speed, has a simple and reliable structure, and is easy to maintain and service. Preferably, a plurality of supporting claws are symmetrically arranged on the outer periphery of the ejection plate 62 to increase the supporting area, can stably support the stamping parts, and prevent the material from slipping or tipping over during the ejection process. The outer contour of the ejection port 22 is matched with the outer contour of the ejection plate 62, and the matching effect is good.

[0029] The loading robot 8 is arranged on the frame 1, and can move the stamping parts located at the position of the temporary storage support device 7 to the feeding conveyor belt 3. The loading robot 8 includes a pillar 81, a cross bar 82, a traverse seat 83, a traverse cylinder 84, a lifting cylinder 85 and a suction cup seat 86. The pillar 81 is vertically arranged on the base frame, the cross bar 82 is arranged at the upper end of the pillar 81, the traverse seat 83 is arranged on the cross bar 82 through a slide rail, the traverse cylinder 84 is arranged on the cross bar 82, and can drive the traverse seat 83 to reciprocate on the slide rail, the suction cup seat 86 is arranged on the traverse seat 83 through a guide column assembly 87, and the lifting cylinder 85 is arranged on the traverse seat 83, and can drive the suction cup seat 86 to move up and down relative to the traverse seat 83, so as to achieve the purpose of sucking and placing stamping parts.

[0030] See also Figure 7 The double-sided oiling mechanism 5 includes a driving motor 51, a fixed seat 52, a guide column frame 53, a slide 54, a lower oiling roller 55 and an upper oiling roller 56. The guide column frame 53 is installed on the fixed seat 52, the lower oiling roller 55 is rotatably set on the fixed seat 52, the slide 54 is movably set on the guide column of the guide column frame 53, and the upper oiling roller 56 is rotatably set on the slide 54. The driving motor 51 drives the lower oiling roller 55 and the upper oiling roller 56 to rotate through the transmission component, so that the oiling is uniform.

[0031] During operation, each station shelf 21 of the rotating material tray 2 is filled with stamping parts. The rotating material tray 2 rotates so that one of the station shelves 21 moves to the bottom of the temporary storage support device 7. At this time, the material pushing device 6 pushes up and pushes the stamping parts 9 in the station shelf 21 located above it to pass through the temporary storage support device 7 to a predetermined height position. The loading robot 8 absorbs and moves the stamping parts 9 located at the position of the temporary storage support device 7 one by one to the feeding conveyor belt 3, and then the feeding conveyor belt 3 feeds the stamping parts 9 into the double-sided oiling mechanism 5. After passing through the double-sided oiling mechanism 5, the stamping parts 9 contact the upper and lower surfaces of the stamping parts 9 through the lower oiling roller 55 and the upper oiling roller 56, so as to achieve the purpose of oiling the upper and lower surfaces of the stamping parts 9, and then are transported to the predetermined position by the delivery conveyor belt 4 to wait for the stamping process. Repeat the above steps until the number of stamping parts in the aforementioned workstation warehouse 21 is small and needs to be replaced, such as four or five pieces, etc., depending on the cycle working time of the rotating material tray 2 switching workstation and the loading robot 8. When the number of stamping parts is small, that is, the height of the stamping part at the lowest position is higher than the height of the hook 723 of the temporary storage support device 7, at this time, the hook 723 automatically flips down and positions under the action of its front gravity, and the stamping parts can be supported and stored by the hook 723, which can meet the normal material collection work needs of the loading robot 8 for a short time; just use this time to let the top material device 6 drop to the lowest position, rotate the material tray 2 to switch the workstation, so that the next workstation warehouse 21 moves to the bottom of the temporary storage support device 7, and then the top material device 6 is pushed up to realize a new round of loading action.
