[0036] The utility model provides a turning conveyor.

[0037] Reference Figures 1 to 3The curved conveyor 100 includes a conveying mechanism 110 and a guiding mechanism 120. The conveying mechanism 110 includes a first conveying portion 111 and a second conveying portion 112. The conveying directions of the first conveying portion 111 and the second conveying portion 112 are both extended in a straight line. The two conveying portions are connected to each other to form a conveying line, and a turning area 110a is formed at the connection. The material moves along the conveying line on the first conveying portion 111, and enters the second conveying portion 112 after turning in the turning area 110a. The turning area 110a is installed with a guiding mechanism 120. The guiding mechanism 120 includes a first guiding portion 121 and a second guiding portion 122. The first guiding portion 121 is extended along the first direction, and the second guiding portion 122 is extended along the second direction. Figure 1 As shown by the arrows and symbols, the first direction is the conveying direction of the first conveying part 111 , and the second direction is the conveying direction of the second conveying part 112 . The guide mechanism 120 guides the moving direction of the material to switch from the first direction of the first conveying part 111 to the second direction of the second conveying part 112 .

[0038] Simply put, the material switches from the original longitudinal movement to lateral movement on the conveyor line. Unlike the conventional solution in which the material slowly switches from longitudinal movement to lateral movement, the posture of the material does not change during the switching of the travel direction. The turning action is clean and neat, and the material enters and exits the turning area 110a smoothly and quickly without jamming or delayed deceleration. Continuous turning and transmission of multiple materials can be achieved, maintaining the high transportation efficiency of the assembly line.

[0039] In one embodiment, the first guide portion 121 includes a plurality of first guide wheels 1211, and / or the second guide portion 122 includes a plurality of second guide wheels 1221, and the first guide wheels 1211 and the second guide wheels 1221 are disposed in the steering area 110a and are arranged at intervals along the first direction and the second direction, respectively.

[0040] Please refer to Figure 1 and Figure 4 In this embodiment, the first guide portion 121 includes a plurality of first guide wheels 1211, and / or the second guide portion 122 includes a plurality of second guide wheels 1221. Specifically, the first guide wheels 1211 and the second guide wheels 1221 are both arranged in the turning area 110a for sliding contact with the material, and are arranged on both sides of the conveyor line. Figure 4 As shown, on both sides of the turning area 110a, a plurality of first guide wheels 1211 are arranged at intervals along the first direction, and a plurality of second guide wheels 1221 are arranged at intervals along the second direction, and the connecting lines between the plurality of guide wheels on each side of the conveyor line form a right angle.

[0041] The outer side of the conveyor line has a longer travel than the inner side, so more guide wheels are set on the outer side. In this embodiment, 4 guide wheels are set on the inner side of the turning area 110a, and 15 guide wheels are set on the outer side. Materials enter and exit the turning area 110a and slide in contact with multiple guide wheels, which effectively avoids material jamming in the turning area 110a. There is no need to adjust the posture of the materials for turning, and the movement is simpler.

[0042] In one embodiment, the first guide portion 121 further includes a plurality of first baffles 1212 , which are mounted on the first conveying portion 111 and extend along the first direction; and / or,

[0043] The second guide portion 122 further includes a plurality of second baffles 1222 , which are mounted on the second conveying portion 112 and extend along the second direction, and are used to guide the materials entering and exiting the turning area 110 a .

[0044] Please refer to Figures 1 to 3 In this embodiment, the first guide portion 121 further includes a plurality of first baffles 1212, and / or the second guide portion 122 further includes a plurality of second baffles 1222. Specifically, the first baffle 1212 and the second baffle 1222 are both in the shape of long strips and are arranged on both sides of the conveyor line. The first baffle 1212 is mounted on the first conveying portion 111 and extends along the first direction, and the second baffle 1222 is mounted on the second conveying portion 112 and extends along the second direction. The first baffle 1212 and the second baffle 1222 are arranged close to the guide wheel at one end of the turning area 110a, that is, the material is guided by the first baffles 1212 on both sides of the first conveying portion 111 and then enters the turning area 110a, and contacts with the plurality of guide wheels. With the assistance of the guide wheels, the material switches its traveling direction, enters the second conveying portion 112, and is again guided by the second baffles 1222 on both sides. It can be seen that the baffle plays a guiding role to prevent the material from being skewed or falling on the conveyor line, so that the material can smoothly enter and exit the turning area 110a.

[0045] The spacing between the first baffle 1212 and the first guide wheel 1211 on both sides of the first conveying part 111 matches the length of the material, and the spacing between the second baffle 1222 and the second guide wheel 1221 on both sides of the second conveying part 112 matches the width of the material, that is, multiple materials are arranged along their own width direction on the first conveying part 111 and enter the turning area 110a, the width of the second conveying part 112 is narrowed, and multiple materials are switched to be arranged and moved along their own length direction. The materials do not need to be turned, and continuous transportation can be achieved by switching the travel direction; therefore, the width of the second conveying part 112 can be set to be smaller than the width of the first conveying part 111, thereby reducing the material consumption to save manufacturing costs, and maximizing the use of the transportation space of the conveying mechanism 110, reducing the overall volume of the turning conveyor 100. It should be noted that the first baffle 1212 and the second baffle 1222 can be a whole piece, or a plurality of pieces can be spliced ​​and installed. The spacing and height of the baffles on both sides of the conveying line can be designed according to the specifications of the material, and are not specifically limited here.

[0046] It should be noted that the angle between the conveying directions of the first conveying part 111 and the second conveying part 112 is a right angle. Specifically, considering the installation and loose deformation of mechanical parts, it is difficult to make the conveying directions of the two conveying parts completely vertical. Structural deformation or installation errors may cause the angle to increase or decrease. Therefore, the angle between the first direction and the second direction is limited to between 85° and 95°. For example, the angle can be 85°, 90° or 95°. During actual installation, it is necessary to try to keep it as close to the vertical 90° as possible to avoid jamming due to an angle that is too large or too small.

[0047] In one embodiment, the first conveying part 111 includes a plurality of first power rollers 1111, and the second conveying part 112 includes a plurality of second power rollers 1121. The plurality of first power rollers 1111 and the second power rollers 1121 are rotatably mounted on the frame 114 and are used to drive the movement of materials.

[0048] Please refer to Figure 4 In this embodiment, the conveying mechanism 110 also includes a frame 114, the first conveying part 111 is a plurality of first power rollers 1111 arranged horizontally on the frame 114, and the plurality of first power rollers 1111 are arranged along a first direction, the second conveying part 112 is a plurality of second power rollers 1121 arranged longitudinally on the frame 114, and the plurality of second power rollers 1121 are arranged along a second direction, the guide wheels and the baffle are both installed on both sides of the frame 114, the first power roller 1111 rotates to drive the material to move along the first direction toward the second conveying part 112, the material moves to the turning area 110a, and the second power roller 1121 rotates to drive the material to move from the turning area 110a along the second direction into the second conveying part 112, thereby realizing the transportation and turning of the material.

[0049] In one embodiment, the conveying mechanism 110 further includes a plurality of driven rollers, and the driven rollers are spaced apart from the first power roller 1111 and the second power roller 1121 .

[0050] Please refer to Figure 1 In this embodiment, the conveying mechanism 110 can also be provided with a plurality of driven rollers. Under the premise of satisfying material conveying, the driven rollers and the first power roller 1111 and the second power roller 1121 are arranged alternately at intervals. The driven rollers are used to cooperate with the power rollers to carry the material to move. The driven rollers do not need to be connected to the power mechanism 130, which can simplify the complexity of the driving mechanism 130 and reduce the difficulty of installing the conveying mechanism 110. In addition, in addition to power rollers, the first conveying part 111 and the second conveying part 112 can also be provided with conveying structures such as belts, which are not specifically limited here.

[0051] In one embodiment, the lengths of multiple first power rollers 1111 located in the turning zone 110a are gradually shortened along the first direction, and the lengths of multiple second power rollers 1121 are gradually increased along the second direction, so that the material enters the turning zone 110a, contacts the first power roller 1111 and the second power roller 1121, and completes the turning.

[0052] Please refer to Figure 1 and Figure 4 In this embodiment, the lengths of the plurality of first power rollers 1111 are gradually shortened in a step-by-step manner along the first direction in the turning area 110a, and the lengths of the plurality of second power rollers 1121 are gradually increased in a step-by-step manner along the second direction in the turning area 110a, and the two are combined to form a turning roller group.

[0053] When the material enters the turning area 110a, the bottom of the material contacts the first power roller 1111 and the second power roller 1121. The first power roller 1111 provides the material with the force required to move in the first direction, and the second power roller 1121 provides the material with the force required to move in the second direction. Therefore, the stepped multiple first power rollers 1111 make the material continue to move until it abuts against the second guide wheels 1221 arranged in the second direction. The stepped multiple second power rollers 1121 drive the material to leave the turning area 110a and move in the second direction into the second conveying part 112 to complete the turning. In this process, the guide wheels guide the material in and out of the turning area 110a, and assist the roller group to switch the direction of travel of the material.

[0054] In one embodiment, one end of each first powered roller 1111 in the roller group away from the frame 114 is fixedly connected to one end of the corresponding second powered roller 1121 away from the frame 114 .

[0055] Please refer to Figure 4In the present embodiment, each first power roller 1111 of the roller group is connected to one of the corresponding second power rollers 1121. Specifically, one end of the first power roller 1111 and the second power roller 1121 is fixed on the frame 114, and the other end is provided with a connecting part 113. The first power roller 1111 is connected to the connecting part 113 of the second power roller 1121 through the connecting part 113. Furthermore, a threaded hole is provided on the connecting part 113, and the two connecting parts 113 are fixed by bolts, so that the first power roller 1111 and the second power roller 1121 form an L-shaped connection structure to improve the conveying stability of the roller group.

[0056] It should be noted that in addition to providing the connecting portion 113, in some other embodiments of the present invention, the connecting portion 113 can be replaced by a connecting piece, such as a right-angle connecting plate, which is connected to the two power rollers respectively by fasteners such as screws to achieve fixation. In addition to this, other connecting structures can also be used, which are not specifically limited here.

[0057] In one embodiment, the curve conveyor 100 further includes a power mechanism 130 , and the power mechanism 130 is used to drive the first power roller 1111 and the second power roller 1121 to rotate.

[0058] In this embodiment, the turning conveyor 100 also has a power mechanism 130 for providing power to the conveying mechanism 110, and the power mechanism 130 is used to drive the first power roller 1111 and the second power roller 1121 to rotate together. The common power mechanism 130 has a motor (not shown), which is usually installed on the frame 114 and connects the first power roller 1111 and the second power roller 1121 through a transmission structure such as a pulley. Since the power mechanism 130 can be a variety of schemes, the above scheme is one of them, and other schemes or a combination of multiple schemes can also be used, so no specific limitation is made.

[0059] In one embodiment, the power mechanism 130 includes a chain 131 and a gear 132 , one end of each of the first power roller 1111 and the second power roller 1121 passing through the frame 114 is connected to the gear 132 , and the chain 131 is in transmission connection with the plurality of gears 132 .

[0060] Please refer to Figure 2 and Figure 3In this embodiment, the power mechanism 130 includes an annular chain 131 and a plurality of gears 132. A gear 132 is connected to one end of each of the plurality of first power rollers 1111 and the second power roller 1121 that pass through the frame 114. The annular chain 131 is sequentially overlapped on the plurality of gears 132. A motor (not shown) is arranged inside the frame 114. The output end of the motor extends out of the frame 114 and is connected to the gear 132. The chain 131 is also wound around the gear 132. The motor drives the chain 131 to rotate through the gear 132, so that the plurality of first power rollers 1111 and the second power roller 1121 rotate. As can be seen from the above, the use of a transmission sprocket structure can enable a plurality of rollers to rotate simultaneously, thereby improving the material transportation rate.

[0061] The utility model also proposes an assembly line conveying system 200, which includes a centrifugal cup tray 210, a centrifugal cup 220 and a turning conveyor 100. The specific structure of the turning conveyor 100 refers to the above embodiment. Since the assembly line conveying system 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0062] Please refer to Figures 1 to 4 The centrifuge cup 220 is loaded in the centrifuge cup tray 210 for placing the whole blood sample. The turning conveyor 100 is used to drive the centrifuge cup tray 210 to move. The width of the first conveying part 111 matches the length of the centrifuge cup tray 210. The width of the second conveying part 112 matches the width of the centrifuge cup tray 210. Multiple centrifuge cup trays 210 are arranged along their own width direction on the first conveying part 111. When entering the second conveying part 112, multiple centrifuge cup trays 210 are arranged along their own length direction, realizing continuous turning transportation while maintaining the original posture.

[0063] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
