Description

Technical Field

[0001] This utility model relates to a feeding auxiliary tooling, specifically a pre-positioning tooling for feeding sheet products. Background Technology

[0002] When processing sheet products, they need to be removed from the production line and placed into the processing fixtures of the processing equipment. To make full use of the processing time, a pre-positioning station can be set up between the production line and the processing equipment to temporarily store the products, facilitating subsequent loading of sheet products. At the pre-positioning station, because some liquid may remain on the surface of the sheet products after the previous processing, they may stick together when stacked. This can lead to multiple stuck sheet products being picked up at once during subsequent handling. If these stuck sheet products are placed into the processing equipment for processing, it can damage the sheet products and, in severe cases, damage the processing equipment itself.

[0003] Therefore, there is an urgent need for a pre-positioning fixture for feeding sheet products to avoid sticking when handling sheet products and to facilitate the feeding operation of sheet products. Utility Model Content

[0004] The purpose of this utility model is to provide a pre-positioning fixture for feeding sheet products, so as to solve the problem that sheet products stacked together stick together and are prone to damage to the products or processing equipment during subsequent processing.

[0005] This utility model is implemented as follows: a pre-positioning fixture for feeding sheet products includes a pre-positioning plate, on which a plurality of placement slots are provided, and on which a plurality of air inlet channels and a plurality of air outlet channels are provided. Each placement slot is simultaneously connected to at least one air inlet channel and at least one air outlet channel. An air inlet pipe is provided in the air inlet channel for connecting to an air source.

[0006] As a further improvement of this utility model, the air inlet channel and the air outlet channel are through groove structures opened on the upper surface of the prepositioning plate. The inner end of the air inlet channel and the inner end of the air outlet channel are connected to the inner cavity of the placement groove, and the outer end of the air inlet channel and the outer end of the air outlet channel extend to the side surface of the prepositioning plate.

[0007] As a further improvement of this utility model, the depth of the air inlet channel and the air outlet channel are the same and both are less than or equal to the distance from the bottom surface of the placement groove to the upper surface of the prepositioning plate, and the depth of the air inlet channel and the air outlet channel is greater than the thickness of a sheet product.

[0008] As a further improvement of this utility model, the length direction of the air inlet channel and the air outlet channel is the radial direction of the placement groove.

[0009] As a further improvement of this utility model, a ring-shaped bottom plate is provided at the bottom of the placement groove.

[0010] As a further improvement of this utility model, several through holes are provided on the annular base plate.

[0011] As a further improvement of this utility model, several of the placement slots are evenly distributed around the center of the prepositioning disk.

[0012] As a further improvement of this utility model, in any one of the placement slots, the angle formed by the line connecting the inner end of the air inlet channel to the center of the placement slot and the line connecting the inner end of the air outlet channel to the center of the placement slot is greater than or equal to 90°.

[0013] As a further improvement of this utility model, a central hole is provided in the center of the prepositioning disk, and at least one auxiliary exhaust channel is provided between each placement slot and the central hole.

[0014] As a further improvement of this utility model, a positioning mark is provided on the upper surface of the pre-positioning disk.

[0015] This invention features a pre-positioning tray with several placement slots, each capable of holding multiple sheet products. Since the position of the pre-positioning tray is fixed, the positions of each placement slot are also fixed, facilitating the simultaneous loading of multiple sheet products from the sheet product loading pre-positioning fixture. Each placement slot is connected to an air inlet channel and an air outlet channel. After the sheet product is lifted to a certain height, airflow is blown into the placement slot through the air inlet channel. This airflow separates two sheet products that are stuck together from their contact surfaces. The airflow then exits through the air outlet channel after passing through the gap between the two sheet products. This invention effectively separates two sheet products that are stuck together when picking them up, preventing damage to the sheet products or processing equipment in subsequent processing steps.

[0020] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] like Figure 1 , Figure 2 as well as Figure 3 As shown, this utility model is a pre-positioning fixture for feeding sheet products, including a pre-positioning tray 1. The pre-positioning tray 1 has an overall disc-shaped structure and is generally fixed, capable of being fixedly installed on a frame. Several placement slots 2 are formed on the upper surface of the pre-positioning tray 1. The placement slots 2 are shaped like sheet products and are used to place sheet products. The placement slots 2 are generally circular. The placement slots 2 have a certain thickness, allowing them to stack a certain number of sheet products.

[0023] To enable the rapid separation of two stacked sheet products when retrieving them from the placement slot 2, several air inlet channels 3 and several air outlet channels 4 are provided on the pre-positioning tray 1. Each placement slot 2 is simultaneously connected to at least one air inlet channel 3 and at least one air outlet channel 4. An air inlet pipe 5 is installed in the air inlet channel 3, which is used to connect to an air source. When retrieving the top sheet product, the air source delivers airflow to the air inlet channel 3 through the air inlet pipe 5. The airflow passes through the air inlet channel 3 and blows into the placement slot 2, entering the gap between the top sheet product and the adjacent sheet product below it, thereby separating the two sheet products. The top sheet product is removed, and the sheet products below it fall back to their original positions under their own gravity.

[0024] Among them, the air intake channel 3 and the air outlet channel 4 are through slot structures opened on the upper surface of the prepositioning plate 1. The inner end of the air intake channel 3 and the inner end of the air outlet channel 4 are connected to the inner cavity of the placement slot 2, and the outer end of the air intake channel 3 and the outer end of the air outlet channel 4 extend to the side surface of the prepositioning plate 1.

[0025] Furthermore, the inlet channel 3 and outlet channel 4 have the same depth, and the depth of both inlet channel 3 and outlet channel 4 is less than or equal to the distance from the bottom surface of the placement tank 2 to the upper surface of the prepositioning plate 1. Simultaneously, the depth of inlet channel 3 and outlet channel 4 is greater than the thickness of a sheet product. When picking up a sheet product, the topmost sheet material is first raised to a certain height, so that its lower surface is higher than the bottom surface of inlet channel 3 and outlet channel 4. The airflow from inlet channel 3 enters the gap between the topmost sheet product and the adjacent sheet product below it. The airflow carries away the liquid on the surface of the sheet product and simultaneously pushes the two sheet products apart, causing them to separate. The topmost sheet product is picked up by the feeding device and transported to the processing equipment, while the sheet products below it fall back to their original position under their own gravity after separation.

[0026] The length direction of the air inlet channel 3 and the air outlet channel 4 is the radial direction of the placement slot 2. The airflow is blown in from the radial direction of the sheet product, which can maximize the utilization of the airflow. The length direction of the air outlet channel 4 is the radial direction of the placement slot 2, which facilitates the rapid discharge of gas in the placement slot 2.

[0027] To further improve the separation effect, in any one of the placement slots 2, the angle formed by the line connecting the inner end of the air inlet channel 3 to the center of the placement slot 2 and the line connecting the inner end of the air outlet channel 4 to the center of the placement slot 2 is greater than or equal to 90°. If the angle is less than 90°, the airflow needs to turn back and exit after entering the gap between the upper and lower sheet products, and the airflow may not be able to completely separate the two sheet products and will be discharged.

[0028] To facilitate the retrieval of the bottom sheet product, the bottom end of the placement slot 2 is open. At the same time, a ring-shaped bottom plate 6 is provided on the inner side wall of the bottom of the placement slot 2. The ring-shaped bottom plate 6 supports the lower surface of the bottom sheet product. Since the contact area between the ring-shaped bottom plate 6 and the lower surface of the sheet product is small, the sheet product can be easily separated from the ring-shaped bottom plate 6.

[0029] Furthermore, a number of through holes 7 are provided on the annular base plate 6. The through holes 7 are evenly distributed around the center of the annular base plate 6. The through holes 7 facilitate the discharge of liquid on the one hand, and further reduce the contact area between the annular base plate 6 and the lower surface of the sheet product on the other hand, so as to facilitate the separation of the sheet product from the annular base plate 6.

[0030] In order to facilitate the feeding device to simultaneously pick up multiple sheet products from the prepositioning fixture of this utility model, a prepositioning plate 1 is provided with multiple placement slots 2, and the multiple placement slots 2 are evenly distributed around the center of the prepositioning plate 1.

[0031] A number of mounting holes 10 are provided on the prepositioning plate 1. The prepositioning plate 1 is fixed in a predetermined position by installing connectors in the mounting holes 10.

[0032] like Figure 3 As shown, in one embodiment of this utility model, in addition to the air outlet channel 4, a central hole 8 is provided in the center of the prepositioning disk 1, and at least one auxiliary exhaust channel 9 is provided between each placement slot 2 and the central hole 8. The auxiliary exhaust channel 9 can effectively improve the exhaust efficiency, improve the flow direction of the airflow, and facilitate the rapid separation of the upper and lower sheet materials.

[0033] like Figure 3 As shown, in one embodiment of the present invention, a positioning mark 11 is provided on the upper surface of the prepositioning plate 1, and the feeding device can determine the position of the prepositioning plate 1 or the placement slot 2 through the positioning mark 11.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
