Detailed Description
The present invention will be described in further detail with reference to specific examples.
Example (b):
as shown in fig. 1 and 2, the utility model discloses a first-in first-out temporary storage machine, including conveyor 1 that is used for carrying the product, be located conveyor 1 side keep in frame 2, be used for carrying the product to move between conveyor 1 and keep in frame 2 and move and carry device 3 and be used for controlling to move and carry device 3 and send the product back to the PLC controller (not shown) on conveyor 1 according to the order that the product was deposited. The buffer is generally placed between a preceding processing unit and a subsequent processing unit, and the conveyor 1 is used to perform the product transition. The use of the buffer 2 enables the storage of products and the transport of products to be independent of each other, and the PLC controller is a device having internal storage, performing logic operations, and sequence control, and thus can be used to manage the first-in first-out of products. When a product is processed for the previous time but a subsequent processing device is not idle, the conveying device 1 firstly stops the product at a proper position, the transferring device 3 takes the product away from the conveying device 1, transfers the product into a certain storage space on the temporary storage rack 2, then the transferring device 3 returns to the initial position, if temporary storage is needed, the conveying device 1 moves the next product to the proper position, the transferring device 3 takes the product away, places the product into another storage space of the temporary storage rack 2, then the transferring device 3 returns to the initial position again, and so on, and the PLC records the storage sequence of the product. If the latter processing equipment is idle, the transferring device 3 can send the products back to the transferring device 3 in sequence according to the storage sequence, and the transferring device 3 sends the products to the latter processing equipment for processing, so that the first-in first-out of the products is ensured, and the automatic transferring device is suitable for the working occasions of the products with ordered management requirements.
As shown in fig. 2, the conveying device 1 includes a plurality of conveying shafts 11 disposed at the same height, and the conveying shafts 11 are used to convey the products in a horizontal direction perpendicular to the axis thereof. The conveying shaft 11 can horizontally move the product, and the conveying shaft 11 is relatively low in bearing capacity and is relatively suitable for plate-shaped products.
As shown in fig. 1, the transfer device 3 includes a material taking mechanism 31, an elevation module 32 for controlling the material taking mechanism 31 to move up and down, and a horizontal movement module 33 for controlling the material taking mechanism 31 to move in a direction perpendicular to the conveying direction of the conveying device 1. The lifting module 32 and the horizontal moving module 33 jointly control the material taking mechanism 31 to move in a vertical plane perpendicular to the conveying direction, and the assembly mode can be that the lifting module 32 drives the horizontal moving module 33 to move, or the horizontal moving module 33 drives the lifting module 32 to move. After the product is stopped at a proper position of the conveying device 1, the material taking mechanism 31 can pick up the product from the position, then the lifting module 32 drives the material taking mechanism 31 to enable the product to ascend to one side of the temporary storage frame 2, and then the horizontal moving module 33 drives the material taking mechanism 31 to convey the product into the temporary storage frame 2 to complete placement; when the product is to be placed back on the conveyor 1, the above action is reversed.
As shown in fig. 2, the material taking mechanism 31 includes a plurality of support rods 311 arranged side by side, the support rods 311 are parallel to the conveying shafts 11, the distance between adjacent conveying shafts 11 is capable of allowing the support rods 311 to pass through, and the distance between the axes of adjacent support rods 311 is equal to the distance between the axes of adjacent conveying shafts 11. The material taking mechanism 31 with such a structure takes and places products by using a mode of supporting the supporting rod 311, the supporting rod 311 and the conveying shafts 11 are arranged in a staggered mode, and the moving range of the supporting rod 311 is out of the vertical projection range of all the conveying shafts 11. Before taking out the product, the carrier bar 311 is moved to the lower side of the conveying shaft 11, and after the product is in place, the carrier bar 311 is lifted up to allow the product to be carried up by all the carrier bars 311, and then the product can be transferred to the temporary storage rack 2. In practical application, the distance between the axes of the adjacent support rods 311 can be an integral multiple of the distance between the axes of the adjacent conveying shafts 11, and it is only required to ensure that each support rod 311 does not collide with the conveying shaft 11.
As shown in fig. 1 and fig. 2, the temporary storage rack 2 includes a plurality of temporary storage areas arranged up and down, each temporary storage area includes a plurality of temporary storage rods 21 arranged side by side, the spacing distance between the temporary storage rods 21 can allow the support rods 311 to pass through, and the axle center distance between adjacent support rods 311 is equal to the axle center distance of adjacent temporary storage rods 21. The plurality of temporary storage areas form a temporary storage space which is independent from top to bottom. The positional relationship between the buffer levers 21 is the same as the positional relationship between the conveying shafts 11, so that the carrier lever 311 does not collide with the conveying shafts 11 and also does not collide with the buffer levers 21. The axle center distance between the adjacent support rods 311 can be an integral multiple of the axle center distance of the adjacent temporary storage rods 21, and it is only required to ensure that each support rod 311 does not collide with the temporary storage rods 21.
What has been described above is merely some embodiments of the present invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which all fall within the scope of the invention.
