Description

Technical Field

[0001] This utility model belongs to the field of conveying devices, and relates to a conveying system, particularly a flipping conveying system, for stably conveying paper stacks and achieving the flipping action of the support frame with minimal effort. Background Technology

[0002] In the process of producing paper stacks or other long strip stacked materials, the long strip paper stacks fed by the upstream equipment are conveyed by the conveying system and flipped to a predetermined angle before being sent out from the discharge end, so that downstream equipment or personnel can perform subsequent operations on the paper stacks (such as cutting).

[0003] In existing technologies, most conveyor belts that transport paper stacks laterally from the short side to the conveying system are single-sided conveyors. However, when dealing with long, tall, soft, and bulky paper stacks or materials, relying solely on a single-sided conveyor belt and side guards for support or clamping can easily cause paper stack deformation due to friction between the paper stack and the guards. Utility Model Content

[0004] Therefore, the main purpose of this utility model is to provide a flipping conveyor system, in which the flipping mechanism flips the fed paper stack from a vertical position to a horizontal position by a bottom conveyor belt and a support frame with a bearing seat as the rotation center, and then the bottom conveyor belt stably conveys it to the discharge end.

[0005] To achieve the aforementioned objectives, the present invention's flipping conveyor system includes a support frame; a bottom conveyor belt coupled to the support frame via a bearing seat; a flipping mechanism disposed on the support frame to control the support frame's position in a vertical or horizontal position; a fixed-side conveyor belt located in the side-pressure conveying section of the support frame and on the fixed side of the support frame; and a movable-side conveyor belt located in the side-pressure conveying section of the support frame and on the movable side of the support frame. When the support frame is in the vertical position, the paper stack is fed in a transverse direction perpendicular to the conveying direction. The flipping mechanism drives the support frame to flip around the bearing seat as its rotation center in a flipping direction, causing the bottom conveyor belt and the support frame to flip from the vertical position to the horizontal position, and then the bottom conveyor belt conveys the paper stack in a conveying direction. When the paper stack is conveyed by the bottom conveyor belt and passes through the side-pressure conveying section, it is further conveyed by the fixed-side conveyor belt and the movable-side conveyor belt to stabilize the conveying of the paper stack.

[0006] The flipping mechanism includes at least one slide rail connected to the support in a vertical direction; at least one slider slidably connected to the at least one slide rail; at least one swing arm, one end of which is connected to at least one of the sliders; and a drive motor connected to the other end of the at least one swing arm via a shaft. The drive motor drives the at least one swing arm to rotate via the shaft, and the at least one swing arm drives the at least one slider to move along the at least one slide rail.

[0007] The movable side conveyor belt can be adjusted to maintain the relative distance between itself and the fixed side conveyor belt.

[0008] The support frame further defines a guide plate section, and the flipping conveyor system further includes: a fixed side guide plate located in the guide plate section and on the fixed side of the support frame; and a movable side guide plate located in the guide plate section and on the movable side of the support frame, the movable side guide plate corresponding to the fixed side guide plate across the bottom conveyor belt; wherein, when the paper stack is conveyed by the bottom conveyor belt and passes through the guide plate section, it is guided by the fixed side guide plate and the movable side guide plate.

[0009] The movable side guide plate can be adjusted to maintain the relative distance between it and the fixed side guide plate.

[0010] In terms of effectiveness, when the paper stack is conveyed by the bottom conveyor belt, it receives good guidance and auxiliary conveying, which can effectively avoid the problem of paper stack deformation caused by friction between the paper stack and the side of the support. The appropriate downward pressure applied to the paper stack by the movable side guide plate and the movable side conveyor belt can stabilize the conveying of the paper stack and avoid the risk of the paper stack falling apart when it is unpackaged or unshaped.

[0011] Furthermore, the flipping mechanism of this invention has the effect of shifting the center of gravity during flipping control, which gives the flipping mechanism a larger lever arm when it is in a horizontal position, reducing the force required for support. When the flipping mechanism is in a vertical position, the same force can be used to obtain a larger rotation angle of the flipping mechanism, thus avoiding excessive force loss.

[0012] The specific technology used in this utility model will be further explained through the following embodiments and accompanying drawings. Attached Figure Description

[0047] See Figure 1The diagram shows a front view of the tilting conveyor system of this invention. The tilting conveyor system includes a bottom conveyor belt 1, which is attached to a support frame 2 by at least one bearing seat 11. The support frame 2 defines a fixed side 21, a movable side 22, a guide plate section S1, and a side-pressure conveying section S2.

[0048] The bottom conveyor belt 1 can run in one conveying direction M1 under the drive of a bottom conveyor belt drive device 12.

[0049] A fixed side guide plate 31 is disposed in the guide plate section S1 and located on the fixed side 21 of the support frame 2. A movable side guide plate 32 is disposed in the guide plate section S1 and located on the movable side 22 of the support frame 2. The movable side guide plate 32 corresponds to the fixed side guide plate 31 across the bottom conveyor belt 1.

[0050] A fixed-side conveyor belt 41 is disposed in the side-pressure conveying section S2 and located on the fixed side 21 of the support frame 2. A movable-side conveyor belt 42 is disposed in the side-pressure conveying section S2 and located on the movable side 22 of the support frame 2. The movable-side conveyor belt 42 corresponds to the fixed-side conveyor belt 41 across the bottom surface conveyor belt 1.

[0051] The fixed-side conveyor belt 41 and the movable-side conveyor belt 42 can be driven by a fixed-side conveyor belt drive device 43 and a movable-side conveyor belt drive device 44, respectively.

[0052] See Figure 2 The diagram shows that the present invention also includes a flipping mechanism 5 integrated with the support frame 2. The flipping mechanism 5 controls the flipping action of the support frame 2, allowing it to be positioned in a vertical or horizontal position.

[0053] See also Figure 3 As shown, the flipping mechanism 5 includes a drive motor 51, a shaft 52, a swing arm 53, a slider 54, and a slide rail 55. The slider 54 is slidably coupled to the slide rail 55, which is fixed to the support frame 2 in a vertical direction. One end of the swing arm 53 is coupled to the slider 54. The drive motor 51 is coupled to the other end of the swing arm 53 via the shaft 52. In a preferred embodiment, multiple swing arms 53 may be included to cooperate with multiple sliders 54 and slide rails 55.

[0054] See Figures 4A-4F The diagram shows a sequence of actions of the tilting conveyor system of this invention, tilting from a vertical position P1 to a horizontal position P2. The following will be illustrated in conjunction with... Figure 1 , Figure 2 The operation of this utility model will be described.

[0055] like Figure 4AAs shown, when the support frame 2 is in the vertical position P1, an upstream device 7 can feed the paper stack 6 in a transverse direction M2 perpendicular to the conveying direction M1.

[0056] Depending on the size of the paper stack 6, the distance between the movable side guide plate 32 and the fixed side guide plate 31 can be adjusted by adjusting the direction M3, and the distance between the movable side conveyor belt 42 and the fixed side conveyor belt 41 can be adjusted by adjusting the direction M3, so that the paper stack 6 is subjected to appropriate downward pressure and stably conveyed by the bottom conveyor belt 1 (e.g., Figure 4C , Figure 4D (As shown). After the paper stack 6 is fed in and stably positioned, the drive motor 51 of the flipping mechanism 5 drives the swing arm 53 to rotate through the shaft 52, and then the swing arm 53 drives the slider 54 to move along the slide rail 55 and generate displacement in the vertical direction away from the bearing seat 11.

[0057] In this way, the support frame 2 can be rotated about the bearing housing 11 in a rotation direction M4 (e.g., Figure 4E As shown), the bottom conveyor belt 1, together with the support frame 2l, is flipped from the vertical position P1 to the horizontal position P2, thereby causing the plane of the bottom conveyor belt 1 to flip to a horizontal plane (as shown). Figure 4F (As shown).

[0058] When the bottom conveyor belt 1 and the support frame 2 are flipped into a horizontal plane by the flipping mechanism 5, the bottom conveyor belt 1 can transport the paper stack 6 in the conveying direction M1 under the drive of the bottom conveyor belt drive device 12, so that downstream equipment or personnel can carry out subsequent operations on the paper stack 6.

[0059] When the paper stack 6 is conveyed by the bottom conveyor belt 1, the paper stack 6 can be guided by the fixed side guide plate 31 and the movable side guide plate 32 in the guide plate section S1.

[0060] When the paper stack 6 is conveyed by the bottom conveyor belt 1, the paper stack 6 can be auxiliary conveyed by the fixed side conveyor belt 41 and the movable side conveyor belt 42 in the side pressure conveying section S2.

[0061] In this invention, the paper stack 6 is primarily conveyed by the bottom conveyor belt 1. The fixed side guide plate 31, movable side guide plate 32, fixed side conveyor belt 41, and movable side conveyor belt 42 provide guidance and auxiliary conveying to the sides of the paper stack 6, effectively preventing paper stack deformation caused by friction between the paper stack 6 and its sides. Furthermore, the appropriate downward pressure applied to the paper stack 6 by the movable side guide plate 32 and movable side conveyor belt 42 stabilizes the conveying of the paper stack, preventing the risk of the paper stack scattering due to overturning when unpackaged or unshaped.

[0062] In theory, when driving a rotating object, the closer the point of force is to the axis, the greater the force can be used to obtain greater potential energy; conversely, the farther the point of force is from the axis, the less force can be used to obtain less potential energy. If a fixed support point is used to lift and tilt the mechanism, due to angle and lever arm issues, more force may be required to lift or lower the mechanism.

[0063] See also Figure 2 , Figure 3 , Figure 4F As shown, the flipping mechanism 5 of this invention has the function of shifting the center of gravity during flipping control. When the center of gravity of the entire support frame 2 is closer to the shaft 52 of the flipping mechanism 5 in the vertical direction (direction of gravity), most of the weight will be supported by the shaft 52 and the bearing seat 11, so the required driving force is smaller at this time, and larger at the opposite direction. The drive system of this invention uses a fixed-length swing arm 53 in conjunction with the slide rail 55 and the slider 54 to achieve the transfer of the force application point, so that the flipping mechanism 5 is in the horizontal position P2 (refer to the reference). Figure 4F When a larger supporting force is required (as shown), the swing arm 53 moves the slider 54 away from the shaft 52 to obtain a larger lever arm and reduce the force required for support (i.e., the torque of the motor).

[0064] When the flipping mechanism 5 is in the vertical position P1, the swing arm 53 brings the slider 54 close to the shaft 52 (see reference). Figure 3 As shown in the diagram, when the flipping mechanism 5 flips, the center of gravity of the entire support frame 2 in the vertical direction is closer to the shaft 52 (reducing the required driving force). The transfer of the force application point is achieved through the swing arm 53 in conjunction with the slide rail 55 and the slider 54, allowing for a larger rotation angle of the flipping mechanism to be obtained with the same force. Therefore, using the drive system of this invention can avoid excessive force loss.

Any person skilled in the art can modify and vary the above embodiments based on the structural design and concept of this utility model, but such modifications shall still fall within the spirit of this utility model and the patent scope defined below.
