Background
The manufacturing process of the plant fiber molding product comprises the following steps: the plant fiber is firstly formed by suction filtration in a suction filtration forming device to prepare a wet blank of a product, the wet blank is alternately sent into a hot-pressing mould of a hot-pressing forming device heated to a certain temperature for hot-pressing, drying and forming to prepare plant fiber molded products with various shapes, the product produced by the hot-pressing forming device is usually processed or stacked and packaged in the next procedure, for example, the product is subjected to edge cutting, stacking or other post-procedure treatment, and the working position of the edge cutting, stacking or other post-procedure is lower than the output working position of the hot-pressing forming device of the product. Therefore, in the process of manufacturing the plant fiber molded product, a transfer device is used for transferring the product from a high standby position to a low working position.
Adopt among the prior art to transfer the cylinder to drive and transfer sucking disc group to move down and rise to the normal position after the high-order work absorbs the goods, transfer the cylinder and transfer sucking disc group together and move up and down and transfer cylinder mount A5 and send horizontal track A4 along the horizontal direction and carry the goods of inhaling to low work position top, transfer the cylinder and drive again and transfer sucking disc group and move down, directly transfer the sucking of sucking disc group treat that add the goods and send the low work position to, then transfer the cylinder and return.
Under the condition that the height difference ratio between the high waiting position and the low working position is larger, the stroke of the transfer cylinder is required to be large, and the stroke of the transfer cylinder is too large, so that two problems are caused, namely 1, the product transfer time is greatly increased, and 2, the length of a cylinder body of the transfer cylinder is increased by two times, and the horizontal movement and the up-and-down movement stability of the transfer mechanism are greatly reduced.
In addition, the product needs to be turned over before entering the next processing procedure. Because the orientation requirements of the forming and shaping process of the former procedure and the next processing procedure on the concave-convex surface of the product are different. For example, the concave surface of a product mold in the molding and shaping device faces upward, but sometimes for the convenience of positioning of the next process, such as trimming positioning, the convex surface of the product is required to face upward to increase the positioning accuracy, and at this time, the orientation of the concave and convex surfaces of the product is required to be changed before the product enters the position to be cut of the trimming device; or, in order to facilitate the product to be stacked with a film, the product with the net surface upward is changed into a product with a smooth surface upward, and the like. Therefore, in the transfer process, the product is turned upside down and then sent to the next process.
To date, all methods and apparatuses for producing and manufacturing plant fiber molded products are directly transferred to the next process without turning the product direction, which directly affects the positioning accuracy of the product in the next process and limits the range of products in automatic production. So that high quality products cannot be produced and the production varieties are greatly limited.
