Description

Technical Field

[0001] This utility model is a rotary mail sorting device, belonging to the field of sorting. Background Technology

[0002] In the manual sorting process, workers remove paper letters from the conveyor belt and place them on a table. Because workers' arms are relatively short, the maximum surface area of ​​the table is limited to facilitate placing the paper letters on the side of the table away from the workers. This means that the surface area of ​​the table is often small, which affects the temporary storage capacity of paper letters and makes them prone to tilting during stacking, thus affecting the sorting efficiency. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rotary mail sorting device to solve the problems mentioned in the background art. This utility model increases the area for storing paper letters, prevents paper letters from tilting during stacking, and improves sorting efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rotary mail sorting device includes a frame with legs installed at each of the four corners. A disc is provided on the upper side of the frame. A large sprocket is installed at the center of the lower surface of the disc via a connector. A small sprocket is connected to the large sprocket via a chain. A geared motor is installed in the frame via a support. The output end of the geared motor is connected and fixed to the small sprocket. The edge of the upper surface of the disc is recessed downward to form multiple storage slots for storing letters arranged in an annular pattern. The inner side of the upper surface of the disc is recessed downward to form multiple label slots arranged in an annular pattern to cooperate with the storage slots. A notch is provided on one side of each storage slot.

[0005] Furthermore, the connector includes a connecting shaft, the lower surface of the disc is fixedly connected to the connecting shaft, the large sprocket is sleeved on the connecting shaft and fixedly connected to the connecting shaft, and a support beam is rotatably mounted on the lower end of the connecting shaft through a bearing, and both ends of the support beam are fixedly connected to the frame.

[0006] Furthermore, two Z-shaped plates are symmetrically installed on the upper surface of the large sprocket, and the end of the Z-shaped plate away from the large sprocket is connected and fixed to the disc.

[0007] Furthermore, the support member includes a connecting beam, and the frame is provided with a connecting beam. Both ends of the connecting beam are connected and fixed with end beams, and the end beams are connected and fixed with the support legs. The cross-section of the connecting beam is "U"-shaped. A movable seat is slidably installed inside the connecting beam. Four elongated holes are opened on the part of the connecting beam below the reduction motor. Bolts for limiting the relative positions of the movable seat, the reduction motor, and the connecting beam are inserted into the elongated holes. An L-shaped plate is provided on one side of the movable seat and is connected and fixed to the connecting beam. Two positioning screws for pressing the movable seat are threadedly connected to one side of the L-shaped plate.

[0008] Furthermore, multiple U-shaped frames are evenly installed on the upper surface of the frame, and a support roller for supporting the disc is rotatably installed inside the U-shaped frame.

[0009] Furthermore, the lower surface edge of the disk is recessed upward to form an annular groove, and two semi-circular plates are provided in the annular groove. A connecting plate is fixedly connected to the middle of the semi-circular plates, and the connecting plate is connected and fixed to the disk by multiple connecting screws. The roller makes rolling contact with the semi-circular plates.

[0010] Furthermore, a connecting sleeve is installed at the lower end of the outrigger, and a base plate is fixedly connected to the bottom of the connecting sleeve. Anchor holes are provided on the upper surface of the base plate.

[0011] The beneficial effects of this utility model are:

[0012] 1. A disc is installed on one side of the conveyor belt. The disc is driven to rotate by a geared motor. Multiple storage slots are machined on the disc. When workers take paper letters from the conveyor belt, they place them in the storage slots to prevent the paper letters from tilting during stacking and improve sorting efficiency. At the same time, because the disc is driven to rotate by the geared motor, the multiple storage slots on the disc move alternately to the area where workers stand, which helps to increase the surface area of ​​the disc, that is, increase the area for storing paper letters.

[0013] 2. The semicircular plate is installed on the bottom of the disc using connecting screws, so that the roller is in direct contact with the semicircular plate. After long-term use, if the contact part between the semicircular plate and the roller is damaged, the damaged semicircular plate can be replaced by removing the connecting screws. Compared with the method of making the roller directly contact the disc, this avoids replacing the disc directly and reduces the cost of replacing parts.

[0014] 3. Use bolts to connect the movable seat, connecting beam and reduction motor. After loosening the bolts, tighten the positioning screws to make the positioning screws press against the movable seat, increasing the distance between the small sprocket and the large sprocket, thereby adjusting the chain tension. After tightening the bolts, the movable seat is prevented from sliding freely under the restriction of the positioning screws. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1-3 This utility model provides a technical solution: a rotary mail sorting device, including a frame 13, with support legs 7 installed at the four corners of the frame 13, and connecting sleeves 8 installed at the lower ends of the support legs 7. A base plate 10 is fixedly connected to the bottom of the connecting sleeves 8, and foot holes are opened on the upper surface of the base plate 10. The base plate 10 is installed at the required position using screws to complete the position restriction of the frame 13.

[0024] See Figure 1 , Figure 2 , Figure 3 and Figure 5A disc 1 is provided on the upper side of the frame 13. A connecting shaft 19 is fixedly connected to the lower surface of the disc 1. A large sprocket 18 is sleeved on the connecting shaft 19 and fixedly connected to the connecting shaft 19. A support beam 16 is rotatably mounted on the lower end of the connecting shaft 19 through a bearing. Both ends of the support beam 16 are fixedly connected to the frame 13. Two Z-shaped plates 22 are symmetrically mounted on the upper surface of the large sprocket 18. The end of the Z-shaped plate 22 away from the large sprocket 18 is fixedly connected to the disc 1, which improves the stability of the large sprocket 18. The large sprocket 18 is connected to a small sprocket 21 through a chain 20. The output end of the reduction motor 9 is fixedly connected to the small sprocket 21. A connecting beam 15 is provided in the frame 13. Both ends of the connecting beam 15 are fixedly connected to end beams 11. The end beams 11 are fixedly connected to the support legs 7. The cross-section of the connecting beam 15 is "U". The connecting beam 15 has a movable seat 17 slidably installed inside it. The part of the connecting beam 15 below the geared motor 9 has four elongated holes. Bolts for limiting the relative positions of the movable seat 17, the geared motor 9, and the connecting beam 15 are inserted into the elongated holes. One side of the movable seat 17 has an L-shaped plate 24 that is fixed to the connecting beam 15. One side of the L-shaped plate 24 is threaded with two positioning screws 23 for pressing the movable seat 17. The movable seat 17, the connecting beam 15, and the geared motor 9 are connected by bolts. After loosening the bolts, the positioning screws 23 are turned to press the movable seat 17, which increases the distance between the small sprocket 21 and the large sprocket 18, thereby adjusting the tension of the chain 20. After tightening the bolts, the movable seat 17 is prevented from sliding freely under the restriction of the positioning screws 23.

[0025] See 1- Figure 3 The upper surface edge of the disc 1 is recessed downward to form multiple storage slots 2 arranged in a ring at equal intervals for storing letters. The inner side of the upper surface of the disc 1 is recessed downward to form multiple label slots 4 arranged in a ring at equal intervals to cooperate with the storage slots 2. The disc 1 is set on one side of the conveyor belt. The disc 1 is driven to rotate by the geared motor 9, and multiple storage slots 2 are processed on the disc 1. When the staff takes the paper letters from the conveyor belt, they place the paper letters in the storage slots 2 to prevent the paper letters from tilting during the stacking process and improve sorting efficiency. At the same time, because the disc 1 is driven to rotate by the geared motor 9, the multiple storage slots 2 on the disc 1 are moved alternately to the staff standing area, which helps to increase the surface area of ​​the disc 1, that is, increase the area for storing paper letters. A notch 3 is opened on one side of the storage slot 2 to provide space for the staff to insert their hands into the storage slot 2.

[0026] See Figures 1-4Multiple U-shaped frames are evenly installed on the upper surface of the frame 13. A support roller 14 for supporting the disc 1 is rotatably installed inside the U-shaped frame. The lower edge of the disc 1 is recessed upward to form an annular groove. Two semi-circular plates 12 are provided in the annular groove. A connecting plate 5 is fixedly connected to the middle of the semi-circular plate 12. The connecting plate 5 is connected and fixed to the disc 1 by multiple connecting screws 6. The support roller 14 rolls in contact with the semi-circular plate 12. The semi-circular plate 12 is installed at the bottom of the disc 1 by the connecting screws 6, so that the support roller 14 is in direct contact with the semi-circular plate 12. After long-term use, when the contact part between the semi-circular plate 12 and the support roller 14 is damaged, the damaged semi-circular plate 12 can be replaced by removing the connecting screws 6. Compared with the method of making the support roller 14 directly contact the disc 1, the disc 1 is not directly replaced, thus reducing the cost of replacing parts.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
