Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a steel ring feeding device. Background Art

[0002] In the process of die casting production, steel ring loading is required. At present, this process mainly relies on manual operation, that is, the staff needs to manually place the steel rings one by one on the picking position specially designed for the robot. Once the robot recognizes that there is a steel ring on the picking position, it will take it away for the subsequent die casting process.

[0003] However, if the staff is slightly negligent during the loading process, or is unable to replenish the steel rings in time for some reason, the robot may be unable to pick up the materials, thus forcing the entire loading process to come to a halt, which in turn has a serious impact on the operation of the entire production line and may even cause production delays and cost increases.

The plurality of fixed frames 2 correspond one-to-one to the plurality of workstations, and the fixed frames 2 are arranged at the corresponding workstations and are used for feeding a plurality of steel rings. The plurality of groups of material blocking mechanisms 3 correspond one-to-one to the plurality of fixed frames 2, and the material blocking mechanisms 3 are arranged on the feeding rotary table 1, and a group of material blocking mechanisms 3 is composed of at least two material blocking mechanisms 3, and the at least two material blocking mechanisms 3 are distributed at intervals along the periphery of the corresponding fixed frames 2 and cooperate with each other to block and limit the steel rings in the fixed frames 2. The transfer mechanism 4 is provided with a transfer platform 41 which can reciprocate in horizontal and vertical directions. The transfer platform 41 is configured to be movable to a position below the material receiving position 11 to receive the steel ring in the fixed frame 2 and transfer the steel ring to the robot picking position.

[0039] According to the scheme of the embodiment of the utility model, multiple groups of steel rings are arranged on multiple workstations of the loading rotary table 1, and after the steel rings at the previous workstation are picked up, the loading rotary table 1 is rotated to drive the next workstation to move to the receiving position 11 to realize uninterrupted alternating loading of steel rings, thereby ensuring that the robot's picking position is always in a state of no shortage of materials, thereby ensuring the continuity of the loading process and production efficiency.

[0040] The following is a detailed description with specific embodiments:

[0041] The steel ring feeding device is provided with an operating table 5, on which a feeding rotating table 1, a plurality of fixed frames 2, a plurality of groups of material blocking mechanisms 3 and a transfer mechanism 4 are all provided. In this embodiment, three fixed frames 2 are provided, and correspondingly, there are three groups of material blocking mechanisms 3, and one group of material blocking mechanisms 3 is composed of two material blocking mechanisms 3. Emergency stop and start switches are provided on the operating table 5 to ensure that the feeding operation is correct.

[0042] See also Figure 2 The material blocking mechanism 3 includes a blocking cylinder 31 and a blocking shovel 32. The blocking cylinder 31 is arranged beside the corresponding fixed frame 2. The blocking shovel 32 is arranged on the blocking cylinder 31 and connected to the movable end of the blocking cylinder 31. The blocking cylinder 31 and the blocking shovel 32 cooperate to make the blocking shovel 32 extend into the fixed frame 2 to limit the steel ring. In the initial state, the blocking shovel 32 extends into the fixed frame 2, and a plurality of steel rings are manually placed in the fixed frame 2 for loading. At this time, the blocking shovel 32 can play the role of carrying the entire stack of steel rings. It should be noted that the blocking shovel 32 fits the surface of the loading rotary table 1. After the steel rings are loaded in the fixed frame 2, the transfer platform 41 moves horizontally to below the material receiving position 11 and rises in the vertical direction, so that the transfer platform 41 and the surface of the loading rotary table 1 differ by the height of one steel ring. In this way, the blocking cylinder 31 drives the blocking shovel 32 to withdraw, and the entire stack of steel rings falls along the receiving hole 12 to the transfer platform 41 without support. At this time, the second steel ring from the bottom to the top of the entire stack of steel rings is in a position flush with the surface of the feeding rotary table 1. Therefore, when the entire stack of steel rings falls, the blocking cylinder 31 drives the blocking shovel 32 to re-extend into the bottom of the second steel ring in the fixed frame 2 to support the entire stack of steel rings (the edge of the steel ring is chamfered to facilitate the insertion of the blocking shovel 32), and then the transfer platform 41 drives the fallen steel ring to descend and then moves horizontally back to the initial position of the robot picking position for the robot to pick up materials.

[0043] See also Figure 3 Specifically, the transfer platform 41 also includes a plurality of support platforms 411 and a pneumatic clamp 412. The plurality of support platforms 411 are circumferentially spaced along the edge of the transfer platform 41, and a support groove 4111 is provided on the support platform 411 for supporting and limiting the steel ring for the material. When the transfer platform 41 moves below the material receiving position 11 and is raised to a specified position, the steel ring in the fixed frame 2 will fall from the material receiving hole 12, so that the last steel ring at the bottom is sleeved on the support groove 4111 on the plurality of support platforms 411. The pneumatic clamp 412 is arranged on the transfer platform 41 and corresponds to the position of the protruding part of the steel ring, and is used to clamp the protruding part of the steel ring to correct the position of the steel ring. After the steel ring is sleeved on the plurality of support platforms 411, the pneumatic clamp 412 will clamp the protruding part on the steel ring so that the steel ring can be horizontally rotated to the specified position to achieve position correction, which is convenient for the subsequent robot to accurately pick up the material.

[0044] The feeding rotary table 1 is driven by a cam divider 13, a servo motor or a stepper motor. Figure 1 In this embodiment, a three-station cam divider 13 is used to drive the feeding rotary table 1.

[0045] See also Figure 4 The transfer mechanism also includes a transverse movement component 42 and a lifting component 43. The transverse movement component 42 is arranged on the operating table 5, and is used to drive the transfer platform 41 to move horizontally to the position below the material receiving position 11. The lifting component 43 is arranged below the transfer platform 41, and is used to drive the transfer platform 41 below the material receiving position 11 to rise and fall so as to receive the steel ring in the fixed frame 2. The lifting component 43 includes a bearing platform 431 and a lifting cylinder 432. The bearing platform 431 is arranged on the transverse movement component 42 and can move back and forth horizontally along the transverse movement component 42. The lifting cylinder 432 is arranged below the bearing platform 431, and the movable end of the lifting cylinder 432 extends upward through the bearing platform 431 and is connected to the transfer platform 41, and is used to drive the transfer platform 41 to move back and forth in the vertical direction. The transverse movement component 42 includes two linear guide rails 421, two sets of transfer sliders 422 and a transfer cylinder 423. The two linear guide rails 421 are arranged on the operating table 5 and are respectively arranged on both sides of the carrier 431. The two groups of transfer sliders 422 are arranged on both sides of the carrier 431 and correspond to the two linear guide rails 421 one by one. The transfer sliders 422 are slidably arranged on the corresponding linear guide rails 421. The transfer cylinder 423 is used to drive the carrier 431 to move back and forth in the horizontal direction. In this embodiment, a group of transfer sliders 422 is composed of two transfer sliders 422. When in use, the transfer cylinder 423 drives the carrier 431 together with the lifting assembly 43 and the transfer platform 41 thereon to move back and forth in the horizontal direction, and the lifting cylinder 432 drives the transfer platform 41 to move back and forth in the vertical direction under the connection support of the carrier 431.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
