Description

Technical Field

[0001] This utility model belongs to the technical field of feeding equipment, and relates to an automatic feeding machine for irregularly shaped sheets. Background Technology

[0002] Sheet metal parts are commonly used in industrial production processes. The feeding and conveying process involves removing metal sheets from the material frame and transporting them forward. However, for some irregularly shaped sheets, special designs are needed during feeding to ensure that the sheets are neat and orderly.

[0003] Patent application number CN201922027912.9 provides a dual-station integrated feeding and conveying device, including: a conveyor frame with a feeding conveyor line; a receiving frame; and a feeding mechanism, which includes: a feeding guide rail, a feeding seat, a horizontal drive assembly, a picking rod, a vertical drive assembly, and a picking suction cup. When feeding metal sheets, the metal sheet is placed on the receiving frame. The horizontal drive assembly drives the feeding seat to move above the receiving frame. Then, the vertical drive assembly drives the picking rod to descend, and the picking suction cup picks up the metal sheet. The vertical drive assembly then drives the picking rod to rise again, and the horizontal drive assembly drives the feeding seat to move above the receiving frame, placing the metal sheet on the feeding conveyor line. The receiving frame includes: a frame body, several positioning holes on the frame body, and several positioning rods that are fitted with the positioning holes. The positioning rods together form a space that restricts the metal sheet, and the positioning rods position the metal sheet.

[0004] The aforementioned device can constrain irregularly shaped sheets to maintain their regular shape by enclosing them with several positioning rods. At the same time, the feeding process is continuous and stable when a dual-station setup is set up. However, there are still some shortcomings: the feeding track for the sliding of the feeding seat is suspended as a whole, and the feeding track extends from above one material frame across the feeding conveyor line to above another material frame, making the entire feeding track span large and prone to deformation. At the same time, the feeding seat connected to it is also partially suspended, and the resulting off-center load makes the feeding track more prone to deformation, affecting the structural stability. Summary of the Invention

[0005] This utility model addresses the aforementioned problems in existing technologies by providing an automatic feeding machine for irregularly shaped sheet metal. The technical problem this utility model aims to solve is that the existing sheet metal feeding devices lack structural stability.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] An automatic feeding machine for irregularly shaped sheets includes a worktable, a movable seat, a suction cup, and several vertically arranged adjustable baffles. The movable seat can reciprocate relative to the worktable, and the suction cup is mounted on the movable seat and can move up and down relative to the movable seat. The worktable has a horizontally reciprocating material carrier plate on its upper side. The upper side of the material carrier plate has two storage stations for stacking sheet materials. The lower ends of the adjustable baffles are all connected to the upper side of the material carrier plate, and each storage station is surrounded by spaced adjustable baffles. The suction cup faces downwards and is opposite one storage station. When the material carrier plate moves, the suction cup can face downwards and be opposite the other storage station. The translational direction of the movable seat intersects the translational direction of the material carrier plate.

[0008] The suction cup can adhere to the side of the material sheet, thereby lifting it up. The moving seat can drive the suction cup to move horizontally, sending the material sheet on the suction cup to different positions in the horizontal direction to achieve the conveying effect. The adjustable baffle column can be adjusted and locked through the existing waist-shaped hole structure and screw cooperation to meet the limiting requirements of different shaped material sheets. By setting a horizontally movable carrier plate on the worktable, and setting two storage stations on the upper side of the carrier plate, the adjustable baffle column is arranged around the two storage stations at intervals, and the moving direction of the moving seat is intersected with the moving direction of the carrier plate. In this way, the moving seat completes the material discharge in a different translation direction than the carrier plate, separating the switching of storage stations and the material discharge, avoiding the structural instability caused by sharing the translation track. When switching between the two storage stations, it can be achieved independently by the translation of the carrier plate without the moving seat moving. The two storage stations on the same carrier plate are closer together, and the translation distance of the carrier plate is shorter, making its translation structure more stable. Moreover, the carrier plate is supported on the side of the worktable, which also helps to ensure the structural stability.

[0009] In the aforementioned automatic feeding machine for irregularly shaped sheets, the feeding machine also includes a vertically arranged, columnar magnetic sheet separator. The magnetic sheet separator is located around the material storage station, and its lower end can reciprocate along the upper side of the carrier plate towards the material storage station. This columnar magnetic sheet separator, while constraining the position of the carrier plate, also interacts with the sheets to create gaps between adjacent sheets, facilitating single-sheet picking by the suction cup.

[0010] In the aforementioned automatic feeding machine for irregularly shaped sheets, the magnetic sheet separator has a handle on its outer side for easy gripping. This allows the operator to easily adjust the position of the magnetic sheet separator by gripping the handle and applying force.

[0011] In the aforementioned automatic feeding machine for irregularly shaped sheets, a frame is fixedly mounted on the upper side of the worktable, and a movable seat is slidably connected to the frame. A horizontally positioned detection plate is fixedly mounted on the frame. The movable seat can drive the suction cup to move outwards and directly above the detection plate. The detection plate has a clearance hole in the middle. A detection bracket that can move horizontally within the clearance hole is mounted on the frame or the detection plate. Two vertically spaced distance sensors, located above and below the detection plate respectively, are fixedly mounted on the detection bracket. The two distance sensors are coaxially arranged opposite each other. In this way, the suction cup can carry the sheet to the detection plate for release, and it is beneficial to make part of the sheet suspended in the clearance hole. Subsequently, the horizontal movement of the detection bracket can position the sheet between the two distance sensors. This allows for comparison of the signal data from the two distance sensors with the data of a single sheet to determine whether multiple sheets are adhered to the detection plate, thus avoiding the simultaneous processing of multiple sheets and resulting in defects.

[0012] In the aforementioned automatic feeding machine for irregularly shaped sheets, a plurality of limiting blocks are fixedly provided on the upper side of the material carrier plate, arranged at intervals around the clearance holes. These limiting blocks constrain the position of the material carrier plate, thereby ensuring that the distance sensor can accurately move to the position of the material sheet for detection when the detection bracket extends.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] This automatic feeding machine for irregularly shaped sheets separates the switching stroke of the storage station from the material picking and unloading stroke of the moving seat. This ensures stable material output while also making the respective translational track structures more stable, thus guaranteeing structural stability. Attached Figure Description

Detailed Implementation

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figure 1-4 As shown, this automatic feeding machine for irregularly shaped sheets includes a worktable 1, a movable seat 2, suction cups 3, and several vertically arranged adjustable baffles 4. The adjustable baffles 4 and their adjustment structures can refer to the prior art in the background section. The movable seat 2 can reciprocate relative to the worktable 1 through an existing screw drive structure. There are four suction cups 3, all of which are on the movable seat 2 and can be driven by cylinders to move up and down relative to the movable seat 2. The upper side of the worktable 1 is provided with a horizontally reciprocating material plate 5. The upper side of the material plate 5 has two storage stations 51 for stacking material sheets. The lower ends of the adjustable baffles 4 are all connected to the upper side of the material plate 5, and each storage station 51 is surrounded by spaced adjustable baffles 4. The suction cups 3 face downwards and are opposite to one storage station 51. When the material plate 5 moves, the suction cups 3 can face downwards and are opposite to the other storage station 51. The translation direction of the movable seat 2 is perpendicular to the translation direction of the material plate 5. Preferably, the movable base 2 can be equipped with an existing laser displacement sensor to assist the suction cup 3 in accurately moving down to grab the material sheet, and can also automatically determine the material sheet depletion status to allow the movable plate to shift and switch the storage station 51. The feeding machine also includes an existing magnetic sheet separator 6 arranged vertically in a column shape. The magnetic sheet separator 6 is located on the periphery of the storage station 51. The lower end of the magnetic sheet separator 6 can be adjusted and positioned by means of a horizontal waist-shaped hole passing through it and a screw hole on the upper side of the material plate 5. The outer side of the magnetic sheet separator 6 is provided with a handle 61 for gripping. A frame 7 is fixedly mounted on the upper side of the workbench 1. A movable seat 2 is slidably connected to a horizontal rail on the frame 7. A horizontally positioned detection plate 8 is fixedly mounted on the frame 7. The movable seat 2 can drive the suction cup 3 to move outward and directly above the detection plate 8. The detection plate 8 has a clearance hole 81 in the middle. A detection bracket 9 that can move horizontally within the clearance hole 81 is mounted on the frame 7. The detection bracket 9 is driven by a cylinder. Two vertically spaced distance sensors 10 are fixedly mounted on the detection bracket 9, located above and below the detection plate 8 respectively. The two distance sensors 10 are coaxially arranged opposite each other. Several limiting blocks 82 arranged at intervals around the clearance hole 81 are fixedly mounted on the upper side of the material carrier plate 5.

[0022] During material loading, one storage station 51 is located below the moving track of the moving seat 2, while the other storage station 51 is in standby mode. After the suction cup 3 moves down to absorb the material sheet, it is controlled to move up. Then, the moving seat 2 moves outward to above the detection plate 8, and the suction cup 3 moves down to release the material sheet onto the detection plate 8. Subsequently, the detection bracket 9 moves toward the material sheet and detects the thickness of the material sheet through two distance sensors 10 to determine whether there are multiple sheets adhering. After the material sheet in one storage station 51 is exhausted, the material carrier plate 5 moves horizontally along the upper side of the worktable 1 so that the other storage station 51 is located directly below the moving seat 2 to achieve continuous material loading.

[0023] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
