Automatic feeder

Abstract

This invention relates to an automatic feeding device comprising a rotary disk and a positioning device. The positioning device includes a mounting base fixedly mounted on the rotary disk for supporting the product to be processed, and a positioning assembly for positioning the product to be processed on the mounting base. A first positioning member and a second positioning member in the positioning assembly are respectively able to hold the product to be processed against the mounting base under the action of a first driving member and a second driving member, thus positioning the product on the mounting base. When the rotary disk rotates and the positioning device aligns with the position of a pushing device, the driving end of the pushing device engages with the first and second positioning members in the positioning device, causing the first and second positioning members to rotate and disengage from the product to be processed. This allows the product to be placed on the positioning device or removed. This automatic feeding device has a more compact overall structure and occupies less space, making it particularly suitable for the automatic feeding of small-sized, thin-plate-shaped products to be processed.

Description

Technical Field

[0001] This invention relates to a feeding device, and more particularly to an automatic feeding device suitable for small-sized, thin-plate products to be processed. Background Technology

[0002] In automated production equipment, processing devices and feeding devices typically work together to automate product processing and achieve high efficiency. The feeding device transports the product to be processed to a designated position, where the processing head of the processing device aligns with the product before processing. To improve processing efficiency, the product is usually positioned on the conveyor of the feeding device to avoid the processing head needing to adjust its position before each processing cycle.

[0003] For thin sheet-shaped products to be processed, the current practice is to equip each station of the conveyor table with a positioning structure. X-axis pushers, which translate along the X-axis, and Y-axis pushers, which translate along the Y-axis, push the two sides of the product to be processed, allowing the product to cooperate with the positioning structure on the worktable for positioning. However, this method requires X-axis and Y-axis drive mechanisms, such as linear motors or cylinders. This results in a large space requirement in the X and Y axes, leading to an excessively large lateral dimension of the feeding device. Furthermore, the thrust exerted directly on the thin sheet-shaped product by the cylinders or linear motors may damage the product, affecting the production yield. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic feeding device to solve one or more problems of the prior art.

[0014] The second push arm is located below the second swing arm, and the second push arm and the second drive arm are located on opposite sides of the second axis in the horizontal direction.

[0015] In some embodiments, both the first driving member and the second driving member are springs, which are arranged to extend and retract in the vertical direction.

[0016] In some embodiments, the mounting base is provided with a first rotating shaft, the axis of the first rotating shaft forming the first axis, and the first positioning member is rotatably sleeved on the first rotating shaft.

[0019] The second swing arm is oscillatingly disposed in the second receiving groove, the second receiving groove having a second opening facing the second positioning surface, and the second positioning part being exposed outward from the second opening as the second swing arm swings.

[0020] In some embodiments, the mounting base is provided with a first positioning groove and a second positioning groove. The first positioning groove is located on the swing path of the first swing arm, and the first swing arm can be correspondingly inserted into the first positioning groove. The second positioning groove is located on the swing path of the second swing arm, and the second swing arm can be correspondingly inserted into the second positioning groove.

[0021] In some embodiments, the mounting base is provided with a receiving groove, the bottom wall of which forms a bearing surface for supporting the product to be processed. The first positioning surface and the second positioning surface are both circumferential walls of the receiving groove.

When the rotating disk rotates and the positioning device aligns with the pushing device, the driving end of the pushing device can engage with the first and second positioning members in the positioning device, causing the first and second positioning members to rotate and detach from the product to be processed. This allows the product to be placed on the positioning device or removed. This makes the overall structure of the automatic feeding device more compact and occupies less space, while also significantly improving feeding efficiency, especially suitable for automatic feeding of small-sized, thin-plate-shaped products to be processed.

[0049] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0050] See Figures 1 to 17 The automatic feeding device shown is used to position and automatically convey small, thin sheet-shaped products 50 for automatic feeding.

[0051] The automatic feeding device includes a rotary disk 10 and a positioning device 20 disposed on the rotary disk 10. The rotary disk 10 is rotatable about a vertically extending center line of rotation, and multiple processing stations are spaced apart circumferentially on the rotary disk 10. The positioning device 20 includes a mounting base 1 fixedly disposed on the rotary disk 10 for supporting the product 50 to be processed, and a positioning component for positioning the product 50 to be processed on the mounting base 1. The automatic feeding device also includes a rotary drive device 40 for driving the rotary disk 10 to rotate about the center line of rotation, thereby enabling the positioning device 20 to be conveyed to any position circumferentially on the rotary disk 10.

[0052] Referring to the accompanying drawings, in the positioning device 20, a first positioning surface 13 and a second positioning surface 14 are provided on the mounting base 1. The first positioning surface 13 extends along a first direction, and the second positioning surface 14 extends along a second direction. The first direction and the second direction are perpendicular to each other and are both horizontal directions. The positioning assembly includes a first positioning member 3 having a first positioning part 3a and a second positioning member 6 having a second positioning part 6a. The first positioning member 3 and the second positioning member 6 are rotatably mounted on the mounting base 1. The positioning assembly also includes a first driving member 4 for driving the first positioning member 3 to rotate so that the first positioning part 3a moves towards the first positioning surface 13 along the second direction, and a second driving member 7 for driving the second positioning member 6 to rotate so that the second positioning part 6a moves towards the second positioning surface 14 along the first direction. A placement area S for placing the product to be processed 50 is formed between the first positioning surface 13, the second positioning surface 14, the first driving member 4, and the second driving member 7.

[0053] When the product to be processed 50 is placed on the mounting base 1 and located in the aforementioned placement area S, under the action of the first driving member 4 and the second driving member 7, the product to be processed 50 is pushed by the first positioning part 3a along the second direction toward the first positioning surface 13, and by the second positioning part 6a along the first direction toward the second positioning surface 14, so that one side of the product to be processed 50 is in contact with the first positioning surface 13 and the other side is in contact with the second positioning surface 14, thus achieving the positioning of the product to be processed 50 on the mounting base 1. At the same time, the first positioning member 4, the second positioning member 7, the first positioning surface 13 and the second positioning surface 14 also form a barrier around the product to be processed 50, so that the product to be processed 50 is fixed in position on the mounting base 1 and will not shake or shift during the rotation of the rotating disk 10.

[0054] Each processing station of the rotary table 10 is equipped with the aforementioned positioning device 20. The automatic feeding device also includes a pushing device 30, which has a pushing member capable of moving vertically. The pushing member has a driving end 30A located at its upper end. The driving end 30A can be engaged with or disengaged from the first positioning member 3 and the second positioning member 6. Specifically, when the driving end 30A moves upward, it engages with the first positioning member 3 and the second positioning member 6, causing the first positioning part 3a and the second positioning part 6a to move away from the first positioning surface 13 and the second positioning surface 14 respectively, so as to place the product to be processed 50 in the aforementioned placement area S or to remove the product to be processed 50 from the placement area S. When the driving end 30A moves downward, it disengages from the first positioning member 3 and the second positioning member 6, thereby avoiding interference with the rotation of the rotary table 10.

[0055] Thus, when the automatic feeding device is used for the automatic feeding and conveying of the thin plate-shaped product 50 to be processed, an upper and lower material position is formed at the location of the pusher 30, and the loading and unloading operations are performed at the upper and lower material positions; while one or more processing devices can be set at other positions on the circumference of the rotary table 10 to perform multi-station processing on the product 50 to be processed on the positioning device 20, thereby improving processing efficiency.

[0056] When the positioning device 20 rotates to the upper or lower material position, the pushing member in the pushing device 30 rises, causing its driving end 30A to engage with the first positioning member 3 and the second positioning member 6. At this time, the product to be processed 50 can be placed and / or removed. Subsequently, the pushing member descends, and the first positioning member 3 and the second positioning member 6 move under the action of the first driving member 4 and the second driving member 7, thereby positioning the product to be processed 50. The rotating disk 10 rotates, causing the positioning device 20 to rotate with the positioned product to be processed 50, aligning it with the processing device to achieve processing of the product to be processed 50. In this way, automatic positioning and feeding of the product to be processed 50 are achieved. The product 50 to be processed is positioned by the rotational movement of the first positioning component 3 and the second positioning component 6, and the movement of the first positioning component 3 and the second positioning component 6 is controlled by the lifting movement of the pushing device 30. In this way, the entire feeding device can be more compact in spatial layout, the positioning components occupy less space, and avoid them occupying too much table area, which would make the size of the entire feeding device too large and affect the improvement of overall production efficiency.

[0057] Specifically, see Figures 13 to 16 As shown, the first positioning member 3 is rotatably connected to the mounting base 1 about a first axis X1 extending in a first direction; the first positioning member 3 has a first swing arm 31, a first drive arm 32, and a first push arm 33, which are spaced apart from each other on a circumference with the first axis X1 as the center of rotation; the first positioning part 3a is provided on the end of the first swing arm 31; the first drive member 4 is connected to the first drive arm 32; and the first push arm 33 can engage with the drive end 30A of the push member or... The components are arranged separately. Here, the first push arm 33 is located below the first swing arm 31, and the first push arm 33 and the first drive arm 32 are arranged on opposite sides of the first axis X1 in the horizontal direction. The first drive member 4 is specifically a spring, which is arranged to extend and retract in the vertical direction to provide the first drive arm 32 with an elastic force to move upward, so that the first swing arm 31 has a tendency to flip downward and can abut against the product 50 to be processed. When the push member pushes the first push arm 33 upward, the first swing arm 31 flips upward accordingly and moves away from the product 50 to be processed.

[0058] The structure of the second positioning member 6 is similar to that of the first positioning member 3. Specifically, the second positioning member 6 is rotatably connected to the mounting base 1 around the second axis X2, which extends along the second direction. The second positioning member 6 has a second swing arm 61, a second drive arm 62, and a second push arm 63. The second swing arm 61, the second drive arm 62, and the second push arm 63 are distributed at intervals on a circumference with the second axis X2 as the center of rotation. The second positioning part 6a is provided on the end of the second swing arm 61. The second drive member 7 is connected to the second drive arm 62. The second push arm 63 can be engaged or disengaged from the drive end 30A. Here, the second push arm 63 is located below the second swing arm 61, and the second push arm 63 and the second drive arm 62 are horizontally disposed on opposite sides of the second axis X2; the second drive member 7 is also a spring, which is arranged to extend and retract in the vertical direction to provide the second drive arm 62 with an elastic force to move upward, so that the second swing arm 61 has a tendency to flip downward and can abut against the product 50 to be processed; when the push member pushes the second push arm 63 upward, the second swing arm 61 flips upward accordingly and moves away from the product 50 to be processed.

[0059] In specific settings, such as Figures 13 to 16 As shown, a first rotating shaft 2 is provided on the mounting base 1, and the axis of the first rotating shaft 2 forms a first axis X1. A first positioning member 3 is rotatably sleeved on the first rotating shaft 2. The first positioning member 3 has one set or multiple sets that are spaced apart along the axial direction of the first rotating shaft 2 and are independent of each other. Similarly, the mounting base 1 is also provided with a second rotating shaft 5, which is perpendicular to the first rotating shaft 2. The axis of the second rotating shaft 5 forms a second axis X2. A second positioning member 6 is rotatably sleeved on the second rotating shaft 5. The second positioning member 6 has one set or multiple sets that are spaced apart along the axial direction of the second rotating shaft 5 and are independent of each other. In this embodiment, the product to be processed 50 is rectangular, with its length side extending along a first direction and its width side extending along a second direction. Two sets of first positioning members 3 are provided corresponding to the length side of the product to be processed 50, and one set of second positioning members 6 is provided corresponding to the width side of the product to be processed 50.

[0060] See Figures 3 to 12As shown, the mounting base 1 is provided with a first receiving groove 15 and a second receiving groove 16. A first swing arm 31 is swayably disposed in the first receiving groove 15. The first receiving groove 15 has a first opening facing the first positioning surface 13. The first positioning part 3a can be exposed outward from the first opening as the first swing arm 31 swings, so that it can be inserted into the receiving area S and cooperate with the product 50 to be processed. A second swing arm 61 is swayably disposed in the second receiving groove 16. The second receiving groove 16 has a second opening facing the second positioning surface 14. The second positioning part 6a can be exposed outward from the second opening as the second swing arm 61 swings, so that it can be inserted into the receiving area S and cooperate with the product 50 to be processed.

[0061] In this embodiment, the mounting base 1 is provided with a first positioning groove 17 and a second positioning groove 18. The first positioning groove 17 is located on the swing path of the first swing arm 31, and the first swing arm 31 can be correspondingly inserted into the first positioning groove 17. The second positioning groove 18 is located on the swing path of the second swing arm 61, and the second swing arm 61 can be correspondingly inserted into the second positioning groove 18. Thus, when the first swing arm 31 swings toward the product 50 to be processed, the first positioning groove 17 can provide guidance and limitation, so that the first positioning part 3a can stably abut against the product 50 to be processed without causing the product 50 to be processed to deviate. Similarly, when the second swing arm 61 swings toward the product 50 to be processed, the second positioning groove 18 also provides guidance and limitation.

[0062] In the positioning device 20, the mounting base 1 is also provided with a receiving groove. The bottom wall of the receiving groove forms a bearing surface for supporting the product 50 to be processed. The first positioning surface 13 and the second positioning surface 14 are both circumferential walls of the receiving groove, which constitutes the aforementioned receiving area S. The first positioning member 3 is disposed on the side of the receiving groove opposite to the first positioning surface 13, and the second positioning member 6 is disposed on the side of the receiving groove opposite to the second positioning surface 14. The first receiving groove 15 communicates with the receiving groove through a first slot; the second receiving groove 16 communicates with the receiving groove through a second slot. The mounting base 1 is also provided with a vacuum adsorption hole 191. The automatic feeding device also includes a vacuum adsorption member, which is in airflow communication with the vacuum adsorption hole 191 to adsorb and fix the product 50 to be processed onto the mounting base 1.

[0063] The mounting base 1 in this embodiment specifically includes an upper base 12 and a lower base 11 fixedly connected to each other in the vertical direction. The upper base 12 is provided with a square through hole in the vertical direction, and an adsorption base 19 is fixedly disposed in the hole. The adsorption base 19 is disposed in the square through hole. Two adjacent sidewalls of the square through hole form a first positioning surface 13 and a second positioning surface 14, respectively. The upper surface of the adsorption base 19 serves as a bearing surface. A vacuum adsorption hole 19 is disposed on the adsorption base 19 and communicates with the bearing surface. The first positioning groove 17 and the second positioning groove 18 are both disposed on the adsorption base 19. This makes it easier to form and process each component of the entire positioning device, and also facilitates the installation of each first positioning component 3 and second positioning component 6, as well as the first driving component 4 and the second driving component 7.

[0064] Referring to the accompanying drawings, in this embodiment, each positioning device 20 has multiple sets of positioning components on the mounting base 1 to simultaneously position multiple products 50 to be processed. These multiple positioning components can be simultaneously engaged with the drive end 30A of the same set of pushing devices 30, significantly improving feeding efficiency without increasing the number of pushing devices 30. Here, each mounting base 1 has two sets of positioning components, capable of simultaneously positioning two products 50 to be processed.

[0065] See Figure 17 As shown, the jacking device 30 of this embodiment includes a cylinder 301, and the jacking component includes a drive seat 302 and multiple drive rods 303 disposed on the drive seat 302. The drive seat 302 is fixed to the upper end of the piston rod of the cylinder 301, and the multiple drive rods 303 are fixed to the drive seat 302 at intervals. All the first jacking arms 33 and the second jacking arms 63 are arranged in a one-to-one correspondence with the multiple drive rods 303. Each processing station on the rotary disk 10 is provided with a clearance structure for the multiple drive rods 303 to pass through in the vertical direction in a one-to-one correspondence.

[0066] In summary, the automatic feeding device of the present invention uses a rotating disk 10 to transport the product 50 to be processed. The product 50 is placed on a positioning device 20 on the rotating disk 10 and positioned by a positioning component. When the rotating disk 10 rotates so that the positioning device 20 corresponds to the position of the pushing device 30, the driving end of the pushing device 30 can engage with the first positioning member 3 and the second positioning member 4 in the positioning device 20, thereby placing the product 50 to be processed on the positioning device 20 or removing the product 50 to be processed. This feeding device abandons the traditional structure of using a linear motor or cylinder to drive the positioning member, greatly reducing the space occupied by the table, making the overall structure of the automatic feeding device more compact and space-saving, while also significantly improving the feeding efficiency, especially suitable for automatic feeding of small-sized thin plate-shaped products to be processed.
