Description

Technical Field

[0001] The utility model relates to the technical field of a feeding mechanism for a blister tray, in particular to a feeding mechanism for a blister tray. Background Art

[0002] Blister trays, also known as plastic inner trays, are plastic products made by forming rigid plastic sheets into specific grooves using a blister process. During the production process, blister trays typically need to be transported to the corresponding production line, such as from one conveyor belt to the next. However, due to the gap between the two conveyor belts, a loading mechanism is required to load and transport the blister trays.

[0003] There are many types of loading mechanisms on the market, but most still rely on adding a conveyor belt between two conveyor belts to perform conveying operations. While this can continue the loading and conveying process, when the heights of the left and right conveyor belts are inconsistent, adding a corresponding conveyor belt makes it difficult to achieve conveying operation. Furthermore, while the added conveyor belt can be tilted to transport a pallet from a low position to a high position, the tilting range is limited. When the tilt angle is too large, the pallet can easily slip off the conveyor belt, affecting the loading and conveying effect and causing inconvenience to the user. In view of this, we propose a loading mechanism for blister trays. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 4 The present utility model provides a technical solution: a loading mechanism for blister trays, comprising a column 2, mounted between a first conveyor belt 1 and a second conveyor belt 10. A support disc 21 is fixedly mounted on the top of the column 2, a servo motor 25 is fixedly mounted on the support disc 21, an adsorption assembly 3 is provided on the output shaft of the servo motor 25, and the adsorption assembly 3 includes a crossbeam 30 fixedly mounted on the output shaft of the servo motor 25, and the output shaft of the servo motor 25 is fixedly connected to the middle portion of the bottom surface of the crossbeam 30. The blister tray on the first conveyor belt 1 is adsorbed and fixed by the left end of the crossbeam 30, and then driven by the servo motor 25 to move the blister tray above the second conveyor belt 10, thereby realizing a reversing operation by using the servo motor 25 to drive the crossbeam 30 to rotate.

[0027] Specifically, a cylinder 31 is fixedly mounted on each end of the crossbeam 30. The telescopic shaft of the cylinder 31 slides through the end of the crossbeam 30 and is fixedly mounted on a base plate 32. A vent pipe 33 is fixedly mounted on the top surface of the base plate 32, and a guide pipe 37 is fixedly mounted on the vent pipe 33. A plurality of vacuum suction cups 34 connected to the vent pipe 33 are fixedly mounted on the bottom surface of the base plate 32. A vacuum pump 35 is fixedly mounted on each end of the crossbeam 30. A hose 36 is fixedly mounted on the suction end of the vacuum pump 35, and the end of the hose 36 away from the vacuum pump 35 is fixedly mounted on the guide pipe 37. The vacuum suction cups 34 are driven to move by the cylinder 31, and the vacuum pump 35 is operated to cause the vacuum suction cups 34 to perform an adsorption operation.

[0028] In this embodiment, guide posts 39 are fixedly mounted on the top surfaces of both base plates 32, and two symmetrical guide sleeves 38 are fixedly mounted on the bottom surfaces of the two ends of the crossbeam 30. The guide sleeves 38 are respectively mounted on the outside of the guide posts 39 and are slidably connected to the guide posts 39. The guide posts 39 slide within the guide sleeves 38, thereby guiding the movement of the base plates 32.

[0029] Specifically, a fixing plate 20 is fixedly mounted on the bottom end of the column 2, which is fixedly mounted on an external base. Two symmetrical support rods 23 are fixedly mounted on the bottom surface of the support plate 21. Supports 24 are fixedly mounted on the bottom ends of the support rods 23. The angle between the support rods 23 and the column 2 is between 30° and 45°, and the support 24 is fixedly mounted on the external base. The two support rods 23 are used to fix the column 2, ensuring that the structure of the column 2 is more solid and stable.

[0030] Furthermore, a support frame 22 is fixedly mounted on the top surface of the support plate 21. The support frame 22 has a U-shaped structure, and the output shaft of the servo motor 25 slides through the top plate of the support frame 22. A through hole is formed in the top plate of the support frame 22, and a bearing 221 is fixedly mounted inside the through hole. The output shaft of the servo motor 25 passes through the bearing 221 and is rotatably connected thereto. The support frame 22 supports the output shaft of the servo motor 25.

[0031] In addition, the output shaft end of the servo motor 25 is fixedly mounted with a limit plate 26, and the middle portion of the bottom surface of the crossbeam 30 is fixedly mounted on the top surface of the limit plate 26 by a plurality of fastening screws, which facilitates the fixed installation operation.

[0032] When the feeding mechanism for the blister tray of the present invention is in use, the cylinder 31 on the left is started and made to work. When the cylinder 31 works, the telescopic shaft on it is extended to drive the vacuum suction cup 34 to move downward and abut against the blister tray transported on the first conveyor belt 1; then the vacuum pump 35 is started to generate negative pressure at the position of the vacuum suction cup 34, and the vacuum suction cup 34 is used to adsorb on the blister tray. After adsorption and fixation, the cylinder 31 is started, and the telescopic shaft on it is shortened, driving the blister tray to move upward to a suitable height, and then the servo motor 25 is connected to the external power supply and made to work. The machine 25 is working, and the output shaft thereon rotates to drive the crossbeam 30 to rotate 180°. At this time, the cylinder 31 on the left moves to the right, and the cylinder 31 is started. The telescopic shaft thereon extends to drive the vacuum suction cup 34 and the blister tray to move downward, and the blister tray is placed on the second conveyor belt 10. The vacuum pump 35 is then started again so that the vacuum suction cup 34 no longer generates negative pressure for adsorption. The blister tray can fall onto the second conveyor belt 10 under the action of its own gravity, completing the loading and conveying operation; and the cylinder 31 on the right moves to the left to load and convey the next blister tray.
