Description

Technical Field

[0001] The utility model relates to the technical field of product shaping and transportation, and particularly relates to a blank transfer device. Background Art

[0002] After the sheet material is injection-molded, it will be uneven during the demolding process and needs to be shaped. The traditional shaping method uses manual handling to press a pressing plate on the sheet material to achieve shaping. In order to improve efficiency and save manpower, an automated design is required. During the automated design process, the inventor found that, on the one hand, the sheet material shaping requires a certain amount of time, and the sheet material needs to be waited until it is shaped before it can be removed, which results in an empty waiting time for shaping and affects the production efficiency. On the other hand, in order to improve efficiency, it is necessary to ensure that multiple sheet materials are performing the shaping operation, which leads to the need to set multiple positions for pressing the sheet material with pressing plates, resulting in a large occupied space. Summary of the Utility Model

As a preferred solution of the present application, in the reset state, the receiving table is at the third preset position, and a pair of weighing sensors are on the upper side of the receiving table. After the sheet is transferred to the pair of weighing sensors, the sheet is weighed and measured to ensure that the weight of the sheet is within the preset error range.

[0045] Combined with Figure 1 A material plate transfer device shown in the figure, comprising:

[0046] A fixed table 51, on which a material receiving table 52 and a second moving module 53 are provided. The second moving module 53 is used to drive the material receiving table 52 to move, so as to realize the switching movement of the material receiving table 52 between a third preset position and a fourth preset position. When the material receiving table 52 moves to the third preset position, it is used to receive the material plate 21;

[0047] Combined with Figure 5 The pressing plate 6 shown in the figure. When the material plate 21 is placed on the material receiving table 52, the pressing plate 6 is stacked with the material plate 21;

[0048] A stacking bin 55 is provided on the fixed table 51 corresponding to the fourth preset position. The stacking bin 55 is used to stack the material plate 21 and the pressing plate 6. The upper and lower ends of the stacking bin 55 are respectively provided with a discharge port 551 and a feed port 552;

[0049] A material ejecting device 521, which is used to eject the material plate 21 and the pressing plate 6 on the material receiving table 52 into the stacking bin 55 from the feed port 552;

[0050] A discharge station 511 is further provided on the fixed table 51;

[0051] Combined with Figure 6 Shown in the figure, it further includes a transfer module 56. The transfer module 56 is used to transfer the pressing plate 6 in the stacking bin 55 to the material receiving table 52 through the discharge port 551, and transfer the material plate 21 in the stacking bin 55 to the discharge station 511.

[0052] Based on the above structure, the working process of the described material plate transfer device includes the following steps:

[0053] S1: The receiving table 52 returns to the third preset position, and the material plate 21 is transferred to and placed on the receiving table 52 by an external transfer device or manually.

[0054] S2: The transfer module 56 transfers the uppermost pressing plate 6 in the stacking bin 55 out of the discharge port 551 and places it on the receiving table 52.

[0055] S3: The second moving module 53 drives the receiving table 52 to move to the third preset position.

[0056] S4: The ejector device 521 ejects the pressing plate 6 and the material plate 21 on the receiving table 52 into the stacking bin 55.

[0057] S5: Before cycling to the next step S2, the transfer module 56 transfers the uppermost material plate 21 in the stacking bin 55 to 511.

[0058] Steps S1 to S5 are cycled in this way.

[0059] It should be noted that at the beginning of the operation, if there is no pressing plate 6 stacked in the stacking bin 55, in one embodiment, when performing the above steps, the transfer module 56 can be turned off, and when performing step S2, the pressing plate 6 can be manually placed on the material plate 21, and step S5 is not performed. At this time, steps S1 to S4 are cycled until the preset number of alternately stacked pressing plates 6 and material plates 21 in the stacking bin 55 is reached, and then the transfer module 56 is started to perform the above steps S1 to S5. In one embodiment, before starting the transfer module 56, the height of the uppermost pressing plate 6 in the stacking bin 55 needs to reach the position of the discharge port 551.

[0060] In one embodiment, on the receiving table 52, the stacking order of the material plate 21 and the pressing plate 6 is that the material plate 21 is on top and the pressing plate 6 is at the bottom. At this time, the transfer order of the material plate 21 and the pressing plate 6 in steps S1 and S2 can be reversed.

[0061] Therefore, in this embodiment, a material plate transfer device realizes the shaping of the material plate 21 by alternately stacking the pressing plate 6 and the material plate 21 in the stacking bin 55. The stacking bin 55 corresponds to the shaping station and has the advantage of small occupied space. After multiple groups of the pressing plate 6 and the material plate 21 are stacked in the stacking bin 55, the material plate 21 enters from below the stacking bin 55 and is only transferred to the discharging station 511 when it is pushed to the top of the stacking bin 55 by the subsequently entering material plate 21 and pressing plate 6. When the working beat time is determined, by controlling the number of groups of the pressing plate 6 and the material plate 21 kept stacked in the stacking bin 55, the shaping time of the material plate 21 can be ensured to be within the preset range. Moreover, the continuity of the transfer of the material plate 21 to the discharging station 511 can be ensured, without waiting for the shaping time, reducing the time of waiting for the idle beat and improving the transfer efficiency. In addition, during this process, the pressing plate 6 circulates between the material receiving table 52 and the stacking bin 55, and there is no need to additionally set up a station for placing the pressing plate 6, which can further save the floor space of the equipment.

[0062] In this embodiment, a conveyor belt is provided corresponding to the discharging station 511. After the material plates 21 are stacked to a preset height at the discharging station 511, the conveyor belt transfers the stacked material plates 21 out.

[0063] Combined with Figure 3 and 4As shown, in this embodiment, a limiting support part 553 is further included. The limiting support part 553 is movably arranged at the feeding port 552. During the process of the material plate 21 and the pressing plate 6 on the material receiving table 52 being pushed into the stacking bin 55 from the feeding port 552, the limiting support part 553 moves out of the outer sides of the material plate 21 and the pressing plate 6. After the material plate 21 and the pressing plate 6 are pushed above the limiting support part 553, the limiting support part 553 moves into the inner side of the material plate 21 or the pressing plate 6. So as to support the bottom of the material entering the stacking bin 55 by the limiting support part 553 when the material pushing device 521 resets. In this embodiment, the limiting support parts 553 are arranged in pairs on both sides of the stacking bin 55. In this embodiment, the limiting support part 553 is slidably arranged in the horizontal direction. An inclined guide surface 5532 is arranged on the lower side of the front end of the limiting support part 553. By pushing the inclined guide surface 5532 from bottom to top, the limiting support part 553 moves towards the outer side of the stacking bin 55. An elastic part 5531 is connected to the limiting support part 553. The elastic part 5531 is used to apply an elastic force for the limiting support part 553 to enter the inner side of the stacking bin 55. During the process of the material plate 21 and the pressing plate 6 on the material receiving table 52 being pushed into the stacking bin 55 from the feeding port 552, the outer edge of the pressing plate 6 pushes the inclined guide surface 5532, and the limiting support part 553 moves out of the outer sides of the material plate 21 and the pressing plate 6. When the material plate 21 and the pressing plate 6 are pushed above the limiting support part 553, due to the elastic force of the elastic part 5531, the limiting support part 553 moves into the inner side of the stacking bin 55 to support the material above. In this embodiment, a limiting frame 554 arranged outside the stacking bin 55 is further included. A sliding groove 5541 for accommodating the sliding of the limiting support part 553 is arranged on the limiting frame 554. In this embodiment, the elastic part 5531 is a compression spring, and both ends thereof respectively abut against the rear end of the limiting support part 553 and the corresponding inner side wall of the sliding groove 5541. A guide rod 5534 is arranged at the rear end of the limiting support part 553. The guide rod 5534 slidably penetrates through the limiting frame 554, and a corresponding through hole is arranged on the limiting frame 554. A limiting convex part 5533 is arranged at one end of the guide rod 5534 away from the limiting support part 553. The limiting convex part 5533 is used to limit the over - movement of the limiting support part 553 during the reset process. The elastic part 5531 can also adopt a tension spring in other embodiments.

When the weighing sensors 54 move to the upper side of the receiving table 52, they are used to support the transferred material plate 21. In this embodiment, in the reset state, the receiving table 52 is at the third preset position, and a pair of weighing sensors 54 are on the upper side of the receiving table 52. After the material plate 21 is transferred onto the pair of weighing sensors 54, the material plate 21 is weighed and measured to ensure that the weight of the material plate 21 is within the preset error range. If the weight of the material plate 21 exceeds the tolerance, the material plate 21 is transferred out and removed. If the weight of the material plate 21 does not exceed the tolerance, the vertical driving device 541 descends to move the upper end of the weighing sensor 54 below the end surface of the receiving table 52. At this time, the material plate 21 is placed on the receiving table 52, and then step S3 can be executed. It should be noted that when weighing, the pressing plate 6 can be placed on the weighing sensor 54, and the weight of the pressing plate 6 can be subtracted when calculating the overweight. In this embodiment, the vertical driving device 541 is a pair of cylinders. Specifically, a support plate is provided on the weighing sensor 54, and the upper end surface of the support plate corresponds to the bearing surface of the weighing sensor 54.
