DETAILED DESCRIPTION

[0019] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The roller transfer machine provided in this embodiment is mainly used to solve the problem that the existing roller transfer machine can only change the transfer direction of the article horizontally to 90 degrees, which has an angle limitation and is inconvenient to adjust the direction of the article during the transfer process, and provides the following technical solutions. Figure 1-Figure 8 Make a detailed description: A roller transfer machine comprises a frame 1 and a transfer frame 2 rotatably arranged on the frame 1, wherein the frame 1 is used to be placed at one end of a plurality of transmission lines close to each other, and a plurality of first transmission rollers 3 are rotatably passed through both ends of the transfer frame 2, and a plurality of second transmission rollers 4 are rotatably arranged on the opposite sides of the inner wall of the transfer frame 2 and between the first transmission rollers 3 at both ends, such as Figure 3As shown, the first transmission roller 3 is respectively located at the left and right ends of the transfer frame 2, and the second transmission roller 4 is located at the inner walls on both sides of the middle section of the transfer frame 2. The first transmission roller 3 and the second transmission roller 4 located on the same side are connected through the coordinated transmission of the sprocket 5 and the chain 6. There are multiple sprockets 5, and the multiple sprockets 5 are respectively fixed on the first transmission roller 3 and the second transmission roller 4 located on the same side. The chain 6 is wound around several sprockets 5. One end of the first transmission roller 3 is connected to a regulating motor fixed on the transfer frame 2. The regulating motor works, and through the transmission cooperation of the sprocket 5 and the chain 6, the first transmission roller 3 and the second transmission roller 4 can be driven to rotate synchronously in the same direction, so that the materials placed thereon can be moved. The transfer rack 2 is provided with a column shell 7 on the inner bottom wall, and the column shell 7 is located between the second transmission rollers 4 on both sides. A plurality of supporting rollers 8 are rotatably arranged in an array on the top of the column shell 7. The supporting rollers 8, the first transmission roller 3 and the second transmission roller 4 are all located on the same transmission surface and an annular gap is formed between the three. A ring plate 9 which is plugged into the annular gap is movably sleeved on the column shell 7. The transfer rack 2 is provided with a driving member 10, and the driving member 10 is used to drive the ring plate 9 to rise or fall or rotate. When the material is transferred, the material is transferred from one of the transmission lines to the transfer rack 2 (the first transmission roller 3). At this time, the motor is regulated to do work, and the material is first transferred to the transfer rack 2 (the first transmission roller 3) under the transmission cooperation of the first transmission roller 3 and the second transmission roller 4. The material is moved above the supporting roller 8 and the ring plate 9. When the material is above the ring plate 9, the transmission is stopped. At this time, the ring plate 9 is first driven to rise by the driving member 10, so that the ring plate 9 lifts the material and the material is separated from the supporting roller 8. Then the ring plate 9 is driven to rotate, so as to adjust the direction of the material. After the direction of the material is adjusted, the ring plate 9 is driven to fall by the driving member 10, so as to place the material on the supporting roller 8, the first transmission roller 3 and the second transmission roller 4 again. Then, according to the transmission line to be transferred, the transfer frame 2 is rotated and adjusted accordingly, so that the transmission direction of the transfer frame 2 is aligned with the transmission line to be transferred, and then the first transmission roller 3 and the second transmission roller 4 are adjusted to rotate, so as to transfer the material. The material is transported to the transmission line to complete the transfer. In order to make the solution more reasonable, in actual use, a monitoring sensor component aligned with the ring plate 9 is set on the transfer frame 2. The material is detected by the monitoring sensor component, and the conveying of the first transmission roller 3 and the second transmission roller 4 is turned on or off through monitoring, so that the material can be smoothly parked above the ring plate 9, so that the driving member 10 drives the ring plate 9 to lift or adjust the direction of the material. At the same time, when the ring plate 9 rotates to drive the material to rotate, the monitoring sensor component can scan and detect the surrounding side of the material, so as to adjust the rotation amplitude of the material according to the feeding requirements (label position or direction), so as to better control the direction of the material, so as to realize automatic control management; In this solution, the transfer rack 2 is rotatably connected to the frame 1. When the frame 1 is located at the end of the transmission line, the horizontal rotation of the transfer rack 2 can adjust the horizontal transfer angle, so that it is suitable for transmission lines with different numbers and different angles. At the same time, the transfer transmission member on the transfer rack 2 is composed of a supporting roller 8, a first transmission roller 3 and a second transmission roller 4. The three can form a horizontal transmission member, but it has an annular gap and a ring plate 9 that can movably penetrate the annular gap. During normal transmission, the ring plate 9 is lower than the transmission surface and does not affect the normal passage of materials. When it is needed When the material is turned and the orientation is adjusted, the ring plate 9 can be lifted and rotated. The lifting of the ring plate 9 can drive the material to be lifted and lowered. When the ring plate 9 lifts the material to a certain height (the material is separated from the supporting roller 8), its rotation can adjust the orientation of the material. After the orientation of the material is adjusted, the ring plate 9 can be lowered and hidden under the transmission surface, and the material can continue to be transmitted so as to be transferred to different transmission lines. The whole can not only perform horizontal transfer at multiple angles, but also adjust the orientation of the material during the transfer process to meet different feeding and conveying requirements, thereby improving practicality.

[0021] like Figure 5 and Figure 6 As shown, in this embodiment, the driving member 10 includes an electric push rod 1001 and a driving motor 1002 arranged on the inner bottom wall of the transfer rack 2, the piston end of the electric push rod 1001 is connected to an adjusting ring 1003 movably sleeved on the column shell 7, and the ring plate 9 is rotatably connected to the adjusting ring 1003. Preferably, an annular slot is provided at the bottom of the ring plate 9, and an annular plug is configured on the top of the adjusting ring 1003. The annular plug is rotatably inserted in the annular slot, and the longitudinal sections of the annular slot and the annular plug are both configured in a T shape. A gear sleeve 1004 is fixedly provided on the outer surface of the ring plate 9, and the output shaft of the driving motor 1002 is fixedly provided with a first gear meshing with the teeth of the gear sleeve 1004. Wheel 1005, the electric push rod 1001 does work, and its piston end is extended and retracted to drive the adjustment ring 1003 to rise and fall. It should be noted that the tooth length of the tooth sleeve 1004 is longer than the tooth length of the first gear 1005, so that when the ring plate 9 is lifted and lowered at an appropriate height, the tooth sleeve 1004 and the first gear 1005 always maintain a tooth meshing state. Therefore, the drive motor 1002 does work, and its output shaft drives the first gear 1005 to rotate, and the first gear 1005 and the tooth meshing of the tooth sleeve 1004 are utilized to drive the ring plate 9 to rotate, so as to achieve the function of adjusting the lifting and rotation of the ring plate 9.

[0022] like Figure 2 , Figure 5 and Figure 6As shown, in this embodiment, a rotating rod 11 is rotatably penetrated on the opposite side of the inner wall of the transfer rack 2, and a pulley assembly 12 is connected between the two ends of the rotating rod 11 and two of the second transmission rollers 4, respectively. The rotating rod 11 and a plurality of supporting rollers 8 are connected through the coordinated transmission of a toothed belt 13 and a second gear 14. Preferably, an annular groove is provided on the outer surface of the supporting roller 8, and the second gear 14 is fixed in the annular groove, so that the toothed belt 13 is hidden in the annular groove, and does not affect the normal transition transmission of the material. By rotating the rotating rod 11, when the second transmission roller 4 rotates, the belt is linked with the pulley assembly 12. The movable rotating rod 11 rotates synchronously, and with the cooperation of the toothed belt 13 and the second gear 14, it drives several supporting rollers 8 to rotate synchronously, so that the supporting roller 8 and the second transmission roller 4 rotate synchronously in the same direction, so that the supporting roller 8 itself has a rotational force, so that when the material is transferred from the first transmission roller 3 to the supporting roller 8 (when the material is small and the contact area with the second transmission roller 4 is small, and the material mass is heavy), it is convenient to transmit the material to the top of the ring plate 9 for direction control. At the same time, when the direction is adjusted, it is also convenient to transmit the material out of the area above the ring plate 9 to ensure the stability of material transmission.

[0023] like Figure 2 and Figure 3 As shown, in this embodiment, both ends of the transfer rack 2 are connected with a supporting plate 15, and a guide roller 16 is rotatably provided on the supporting plate 15. Since the transfer rack 2 can be rotated as a whole, it is convenient to dock with different transmission lines. There is a certain distance between the end of the transfer rack 2 and the transmission line to avoid collision during rotation switching. The supporting plate 15 (the supporting plate 15 is an arc-shaped structure) and the guide roller 16 are provided to reduce the distance between the transmission end of the transfer rack 2 and the conveying line after the transfer rack 2 rotates, so as to better transfer the materials on the transmission line to the transfer rack 2 or the items on the transfer rack 2 to the transmission line.

[0024] like Figure 2 As shown, in this embodiment, two adjusting members 17 are provided on the transfer frame 2, and the two adjusting members 17 are respectively used to adjust the tension of the two chains 6. Since the first transmission roller 3 and the second transmission roller 4 adopt the coordinated linkage of the chain 6 and the sprocket 5, the coordination of the chain 6 and the sprocket 5 directly affects the transmission continuity (synchronous rotation or synchronous stop) of the first transmission roller 3 and the second transmission roller 4. By setting the adjusting member 17, the tension of the chain 6 is adjusted to facilitate better linkage of the first transmission roller 3 and the second transmission roller 4, thereby ensuring the stability of transmission.

[0025] like Figure 7As shown, in this embodiment, the adjusting member 17 includes a U-shaped frame 1701 arranged on the transfer frame 2, and a bidirectional screw rod 1702 is rotatably penetrated on the opposite sides of the inner wall of the U-shaped frame 1701, and both ends of the bidirectional screw rod 1702 are threadedly sleeved with support rods 1703, and the ends of the two support rods 1703 are provided with pressure wheels 1704, and the two pressure wheels 1704 are respectively rolled and overlapped with the two sides opposite to the chain 6. Preferably, a limiting groove is penetrated at one end of the U-shaped frame 1701 away from the opening The ends of the two support rods 1703 away from the pressure wheel 1704 movably penetrate the limiting groove. When the bidirectional screw rod 1702 is twisted to rotate, under the action of the bidirectional thread and the sliding limit of the limiting groove, the two support rods 1703 can be driven to move synchronously in opposite directions. When the two support rods 1703 approach each other synchronously, the two pressure wheels 1704 respectively contact the upper and lower sides of the chain 6, thereby tightening the chain 6 to achieve tension adjustment and ensure the stability of the transmission cooperation between the chain 6 and the sprocket 5.

[0026] like Figure 4 As shown, in this embodiment, a gantry 18 is provided on the frame 1, and a column 19 is rotatably passed through the gantry 18. The transfer frame 2 is fixedly arranged on the top of the column 19, and a driven bevel gear 20 is arranged on the column 19. A servo motor 21 is provided on the frame 1, and the output shaft of the servo motor 21 is fixedly provided with a transmission bevel gear 22 meshing with the teeth of the driven bevel gear 20. When the servo motor 21 is working, its output shaft drives the transmission bevel gear 22 to rotate, and the teeth of the transmission bevel gear 22 and the driven bevel gear 20 are meshed to achieve the effect of driving the column 19 to rotate, thereby adjusting the rotation of the transfer frame 2 to realize docking and transfer with transmission lines in different orientations.

[0027] like Figure 8 As shown, in this embodiment, a support ring 23 is provided on the frame 1, and an annular groove 24 is opened on the top of the support ring 23, and two support plates 25 are symmetrically provided on the bottom of the transfer rack 2, and balls 26 are rollingly inserted at the ends of the support plates 25, and the balls 26 are rollingly inserted in the annular groove 24. When the transfer rack 2 rotates, the balls 26 at the ends of the support plates 25 roll along the annular groove 24 on the support ring 23, so that the transfer rack 2 is not only a supporting point of the column 19, but the support plate 25 and the support ring 23 form an annular sliding support structure, which can effectively support the transfer rack 2 to ensure the stability of the material during the transfer process.

[0028] like Figure 1As shown, in this embodiment, the frame 1 includes two support plates 101 distributed up and down, and a scissor-type lifting frame 102 is connected between the two support plates 101. The support plate 101 located at the bottom is provided with a universal self-locking wheel 103. Preferably, the transfer frame 2 is arranged on the support plate 101 located at the top. The frame 1 as a whole is composed of two support plates 101 and the scissor-type lifting frame 102. The scissor-type lifting frame 102 can be used to adjust the height of the frame 1, so that the transfer frame 2 can be suitable for transmission lines of different heights. At the same time, it can also meet the transfer and transmission requirements of non-same horizontal planes during the transfer process. By arranging the universal self-locking wheel 103 on the support plate 101 at the bottom, it is convenient to move the frame 1 as a whole, thereby improving practicality.

[0029] like Figure 1-Figure 8 As shown, in this embodiment, a transfer method of a roller transfer machine comprises the following steps: S1: The height of the frame 1 is adjusted by the scissor-type lifting frame 102, so that the transfer frame 2 is flush with the transmission surface of the transmission frame, and the objects on the transmission frame can be transferred to the transfer frame 2. With the cooperation of the first transmission roller 3, the second transmission roller 4 and the supporting roller 8, the objects are transferred to the top of the ring plate 9; S2: The electric push rod 1001 drives the ring plate 9 to rise, so that the object is out of contact with the supporting roller 8, and the driving motor 1002 works, and the teeth of the gear sleeve 1004 and the first gear 1005 are meshed, thereby driving the ring plate 9 to rotate, so as to adjust the position of the object. After the position of the object is adjusted, the electric push rod 1001 drives the ring plate 9 to descend, and the object is placed on the supporting roller 8 again; S3: The servo motor 21 works, and the teeth of the driving bevel gear 22 and the driven bevel gear 20 are meshed, thereby driving the column 19 to rotate, thereby adjusting the direction of the transfer rack 2, so that the transfer rack 2 can dock with other transmission racks. When the docking is completed, the objects are transferred to the transmission rack under the rotation cooperation of the first transmission roller 3, the second transmission roller 4 and the supporting roller 8.

[0030] The working process of the present invention is as follows: the frame 1 is placed at the ends of two or more transmission lines, and the height of the frame 1 is adjusted by the scissor-type lifting frame 102, so that the transfer frame 2 is flush with the transmission surface of the transmission line, and the material on the transmission line can be transferred to the transfer frame 2. With the cooperation of the first transmission roller 3, the second transmission roller 4 and the supporting roller 8, the material is transferred to the top of the ring plate 9, and the electric push rod 1001 drives the ring plate 9 to rise, so that the material is out of contact with the supporting roller 8, and the driving motor 1002 performs work, and the teeth of the gear sleeve 1004 and the first gear 1005 are meshed, thereby driving the ring plate 9 to rotate. Thereby adjusting the direction of the material, after adjusting the direction of the material, the electric push rod 1001 drives the ring plate 9 to descend, and places the material on the supporting roller 8 again, and the servo motor 21 works, and the teeth of the transmission bevel gear 22 and the driven bevel gear 20 are engaged, thereby driving the column 19 to rotate, thereby driving the transfer rack 2 to rotate, changing its transmission direction, so that the transfer rack 2 can dock with other transmission lines. When the docking is completed, the material is transmitted to the transmission line under the rotation cooperation of the first transmission roller 3, the second transmission roller 4 and the supporting roller 8, thereby completing the function of transferring the material from one transmission line to another transmission line.
