Description

Technical Field

[0001] This utility model relates to the field of automatic feeding device technology, and in particular to a synchronous dual feeding device. Background Technology

[0002] Automatic feeding devices are typically installed on or at the front end of automated production or assembly equipment for automatic material feeding. Currently, production generally adopts a mode where one feeding device conveys one material at a time. However, with the gradual optimization and improvement of automated production technology and automatic conveyor equipment, more and more automated equipment can handle two or more materials simultaneously. This often requires the installation of two or more traditional feeding devices, resulting in high production costs, large footprint, increased workload for machine operators, and increased probability of machine downtime or even mechanical damage due to human error such as material shortages. Utility Model Content

By setting each positioning component as an L-shaped structure and setting the first and second parts of two adjacent positioning components adjacent to each other and extending in the same direction and arranged in a straight line, the first and second parts of the two adjacent positioning components can be fed in the same direction to the bottom of the two feeding parts by rotating the base. In conjunction with the lifting feeding mechanism below, it can meet the feeding needs of synchronous step conveying of two materials. Moreover, the overall structure of the device is simple, the layout is compact, and the footprint is small.

Each first part and second part can fix a number of materials stacked along the Z direction.

[0007] The rotary feeding mechanism includes a rotating shaft located on the central axis of the base. The rotating shaft is connected to the first driving device and can rotate under its drive, thereby driving the base to rotate synchronously.

Each top plate is connected to a second driving device via a transmission device and can move along the Z direction under its drive, so as to simultaneously lift and send the two stacks of materials placed on the adjacent first and second parts of the two adjacent positioning components to the area below the two loading parts of the material transfer mechanism.

[0009] As a further explanation of the above technical solution:

[0010] In the above technical solution, each positioning component includes several Z-direction extending limiting rods, and the several limiting rods together form the first part and the second part. An anti-cavity groove adapted to the top plate is formed on the inner side of each first part and the second part on the base.

[0011] In the above technical solution, each of the transmission devices includes a Z-direction extending guide rail, each of the guide rails has a sliding plate slidably mounted on it, and each of the sliding plates is connected to a second driving device in a transmission manner. Each of the sliding plates has one or more Z-direction extending top rods, and the upper end of a plurality of the top rods is provided with a top plate.

[0012] In the above technical solution, each of the slide plates is further provided with a reversing component between it and a second driving device.

Each sensor can detect the material on one of the feeding components and / or the upper end of one of the first / second parts and is electrically connected to the first driving device.

[0014] In the above technical solution, the base is a disc structure.

[0015] In the above technical solution, the base is a square structure, and the first part and the second part on each group of positioning components are respectively arranged parallel to one side wall of the base.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting each positioning component as an L-shaped structure and setting the first and second parts of two adjacent positioning components adjacent to each other and extending in the same direction and arranged in a straight line, the first and second parts of the two adjacent positioning components can be sent to the bottom of the two feeding parts in the same direction by rotating the base.

[0024] like Figure 1-2 The synchronous dual-feeding device includes a material rack 20, a rotary feeding mechanism 30, and a lifting feeding mechanism 40, wherein:

[0025] The material rack 20 includes a base 21 and four sets of L-shaped positioning components 22 that are equally spaced along the circumference on the base 21. Each positioning component 22 includes a first part 1 and a second part 2 that are provided on the base 21 and extend along the X and Y directions respectively. Each first part 1 and second part 2 is located on or near the outline edge of the base 21. The first part 1 of each positioning component 20 is adjacent to the second part 2 of another positioning component 20, and the two extend in the same direction and are located on the same straight line. Each first part 1 and second part 2 can fix several materials 3 stacked along the Z direction.

[0026] The rotary feeding mechanism 30 includes a rotating shaft 31 located on the central axis of the base 21. The rotating shaft 31 is connected to the first driving device 32 and can rotate under its drive, thereby driving the base 21 to rotate synchronously.

[0027] The lifting and feeding mechanism 40 includes two top plates 4 located directly below the first part 1 and the second part 2 of two adjacent positioning components 22. Each top plate 4 is connected to a second driving device 42 via a transmission device 41 and can move along the Z direction under its drive, so as to simultaneously lift up the two stacks of materials 3 placed on the adjacent first part 1 and the second part 2 of the two adjacent positioning components 20 and send them to the area below the two loading parts 61 of the material transfer mechanism 60.

[0028] This utility model sets each positioning component 22 into an L-shaped structure and arranges the first part 1 and the second part 2 of two adjacent positioning components 22 adjacent to each other, extending in the same direction and arranged in a straight line. By rotating the base, the adjacent first part 1 and the second part 2 of two adjacent positioning components 22 can be sent in the same direction to the bottom of the two feeding parts 61. In conjunction with the lifting and feeding mechanism 40 below, it can meet the feeding needs of synchronous step conveying of two materials 3. Moreover, the overall structure of the device is simple, the layout is compact, and the footprint is small.

[0029] like Figure 3 As shown, each positioning component 22 includes several Z-oriented limiting rods 5, which together form a first part 1 and a second part 2. A clearance groove 6, adapted to the top plate 4, is formed on the inner side of each first part 1 and second part 2 on the base 21. In this embodiment, several limiting rods 5 are used to form a material storage area for a stack of materials 3, which can both limit and guide the material, and is easy to assemble and disassemble, facilitating quick adjustments based on the actual material structure.

[0030] like Figure 4As shown, each transmission device 41 includes a Z-direction extending guide rail 7, and a sliding plate 8 is slidably mounted on each guide rail 7. Each sliding plate 8 is connected to a second drive device 42. Each sliding plate 8 has one or more Z-direction extending push rods 9, and a top plate 4 is provided at the upper end of several push rods 9. A reversing element 10 is also provided between each sliding plate 8 and a second drive device 5. Each reversing element 10 is a gear and rack transmission pair, a bevel gear transmission pair, a helical gear transmission pair, or a lead screw and nut transmission pair. Each second drive device 42 is a circular motion drive device. In this embodiment, each second drive device 42 is a stepper motor, and a reversing element 10 is used for reversing transmission in order to effectively utilize space. Only commonly used types of reversing elements 10 are listed here. It should be understood that this is not a limitation on the reversing element 10. Any structural component or assembly with reversing transmission function should be considered to fall within the protection scope of this utility model.

[0031] like Figure 1-2 As shown, in this embodiment, a frame 50 is also included. A base 21 is mounted on the upper end of the frame 50 and slidably connected thereto. A rotary feeding mechanism 30 and a lifting feeding mechanism 40 are both mounted on the frame 50 and below the base 21. Two sensors 11 are also mounted on the frame 50. The two sensors 11 are both located on one side of the base 21 and are respectively located beside a feeding component 61. Each sensor 11 can detect the material 3 on a feeding component 61 and / or the upper end of a first part 1 / second part 2 and is electrically connected to the first driving device 32.

[0032] In this embodiment, the frame 50 is a box structure, which also houses electrical control components and heat dissipation components.

[0033] In one embodiment of this utility model, the base 21 is a disc structure.

[0034] In a preferred embodiment of this utility model, the base 21 has a square structure, and the first part 1 and the second part 2 on each group of positioning components 20 are respectively arranged parallel to one side wall of the base 21. In order to facilitate assembly, positioning and filling of materials, each corner of the base 21 is provided with a chamfered edge 12, and each group of positioning components 20 is located on the side of a chamfered edge 12.

[0035] The feeding process of this utility model is as follows: First, manually or automatically, a stack of materials 3 is loaded into the limiting rods 5 of the adjacent first part 1 and second part 2 of the two adjacent positioning components 22. The first driving device 32 drives the base 21 to rotate, so that the first part 1 and the second part 2 are respectively moved to the side of the material transfer mechanism 60 and located directly below a material transfer component 61. The two second driving devices 42 simultaneously drive the two slide plates 8 to step upward, driving the two top plates 4 to step upward synchronously, lifting the two stacks of materials 3 to the lower end of the two material transfer components 61 so that they can synchronously transfer the materials, thus achieving the purpose of synchronous double feeding. At the same time, stacked materials 3 can continue to be loaded into other positioning components 22. During the feeding process, the two sensors 11 can sense / detect whether there is material 3 at the upper end of each material transfer component 61 or the first part 1 / second part 2 below it. When either sensor 11 does not sense / detect material 3, it sends a feedback signal to the first drive device 32, instructing its drive base 21 to rotate so as to send another set of adjacent second parts 2 and first parts 1 to the bottom of the two material transfer components 61.

[0036] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
