[0001] The utility model relates to glass conveying equipment field especially relates to a flexible shaft conveying device. BACKGROUND

[0002] Glass roller conveying technology mainly includes two forms of hard shaft roller conveying and flexible shaft roller conveying. In glass forming conveying technology, the roller has both forming and conveying glass functions.

[0003] In the prior art, the flexible shaft transmission form in the flexible shaft roller conveying mostly adopts flexible shaft single side transmission, that is, only one end of the flexible shaft in the length direction is provided with a transmission mechanism to drive the flexible shaft to rotate. Due to the characteristics of the flexible shaft itself, the transmission has the characteristics of transmission delay along the axial direction of the flexible shaft, that is, the power input end of the flexible shaft is not synchronized with the end away from the power input end of the flexible shaft, and the flexible shaft also has a certain axial expansion when it is in a bent state. The above characteristics of the flexible shaft can cause the glass to be easily skewed when conveying on the flexible shaft, so that the glass deviates from the conveying roller. Especially for the glass with a relatively long size, the longer the glass is conveyed on the flexible shaft, the greater the deviation of the glass in the conveying process.

[0004] When the above situation occurs in glass forming conveying, the deviation of the conveying will seriously affect the forming precision of the glass, so the flexible shaft conveying structure needs to be improved. CONTENT OF THE UTILITY MODEL

[0013] The utility model is further configured as follows: the connection compensation unit includes a sliding universal coupling, the two ends of the sliding universal coupling are respectively fixedly connected to the sliding end of the flexible shaft body and the power access member at the sliding end, and the sliding universal coupling can change the distance between the sliding end of the flexible shaft body and the power access member at the sliding end.

[0014] The present invention is further configured to include a fixed connecting piece, wherein both ends of the fixed connecting piece are respectively fixedly connected to the fixed end of the flexible shaft body and the power access piece at the fixed end.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention are described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. For ease of explanation, the terms "vertical", "horizontal", "left", "right", "up", "down", "inside", "outside", "bottom", etc. used in this specification to indicate directions or positional relationships are based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present application.

[0030] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0031] Example 1

[0032] As attached Figure 1 and attached Figure 2As shown, a flexible shaft conveying device includes a flexible shaft body 1, a flexible shaft support 2, a connecting mechanism 3 and a transmission mechanism 4.

[0033] Multiple flexible shaft bodies 1 are spaced apart along the conveying direction of the conveying device. The flexible shaft bodies 1 are also provided with a number of rollers (not shown) spaced axially to support the glass being conveyed above the flexible shaft bodies 1. In particular, in this embodiment, the flexible shaft body 1 is a single, integral flexible shaft. In other embodiments, the flexible shaft body 1 may also be formed by axially splicing multiple sections of flexible shaft into a single, integral structure.

[0034] The top of the flexible shaft support 2 contacts the flexible shaft body, thereby providing support for the flexible shaft body 1. In this embodiment, multiple flexible shaft supports 2 are arranged at equal intervals along the length of the flexible shaft body 1 to support the flexible shaft body 1, and multiple rollers are provided between adjacent flexible shaft supports 2. In some other embodiments, only one flexible shaft support 2 may be provided in the middle of the length of the flexible shaft body 1.

[0035] The transmission mechanism 4 provides power for the entire conveying device and transmits the power to each flexible shaft body 1. Driven by the transmission mechanism 4, all flexible shaft bodies 1 rotate synchronously, thereby smoothly and continuously conveying the glass. The transmission mechanism 4 includes a power input member 41, a driving member 42, a driving connection member 43, a driving shaft 44, a power output member 45, and a transmission belt 46.

[0036] The driving member 42 is generally a motor, and the driving connecting member 43 is located between the driving member 42 and the driving shaft 44. The driving connecting member 43 is used to realize power transmission between the driving member 42 and the driving shaft 44, and can be selected from, for example, a gear transmission structure, a sprocket transmission structure or a belt transmission structure.

[0037] The axis direction of the driving shaft 44 is parallel to the conveying direction of the conveying device, and a driving shaft 44 is provided on each side of the conveying direction of the conveying device. In this embodiment, each driving shaft 44 is powered by a driving member 42. In some other embodiments, two driving shafts 44 can be powered by the same driving member 42.

[0038] The axis of the power output member 45 coincides with the axis of the driving shaft 44 . A plurality of power output members 45 are fixed to the driving shaft 44 and are spaced apart along the axis of the driving shaft 44 .

[0039] Both ends of each flexible shaft body 1 are provided with power input members 41 that can rotate synchronously with the flexible shaft body 1 , and the axis of the power input member 41 coincides with the axis of the flexible shaft body 1 in the straight state.

[0040] On the same side of the conveying device, the number and position of the power output members 45 and the power input members 41 correspond one to one. When the driving member 42 drives the driving shaft 44 to rotate through the driving connecting member 43, the driving shaft 44 can drive all the power input members 41 on the same side to rotate synchronously through the power output member 45.

[0041] Specifically, in this embodiment, a flexible transmission is employed between the power output member 45 and the power input member 41, i.e., the power output member 45 serves as a driving pulley and the power input member 41 serves as a driven pulley, connected and transmitting power via a transmission belt 46. In particular, since the power output member 45 and the power input member 41 utilize a belt transmission, to further stabilize the transmission between the power output member 45 and the power input member 41, two or more driven pulleys may be provided at each end of the flexible shaft body 1 as power input members 41, while a corresponding number of driving pulleys may be provided on the driving shaft 44 as power output members 45. The driving and driven pulleys are connected and transmitting power via a matching number of transmission belts 46, thereby further stabilizing the transmission and improving the stability of glass conveying. In other embodiments, the power output member 45 and the power input member 41 may utilize other transmission mechanisms, such as a sprocket transmission, in which case the two may be connected via a chain.

[0042] Thus, each driver 42 in this embodiment can drive all power input members 41 on the side of the current driving shaft 44 to rotate synchronously, and the synchronous rotation of the two drivers 42 can drive the power input members 41 at both ends of each flexible shaft body 1 to rotate synchronously, ensuring the synchronization of the rotation of the two ends of the flexible shaft body 1. In some other embodiments, the transmission mechanism 4 does not need to be provided with a driving shaft 44 and a power output member 45, and the driver 42 can simultaneously drive all power input members 41 located on the same side of the conveying device. For example, when the power input member 41 is a sprocket, all power input members 41 on the same side of the conveying device can be connected to the driver 42 located on that side by a chain, and power can be directly transmitted to the power input member 41 by the driver 42; when the power input member 41 is a pulley, all power input members 41 on the same side of the conveying device can be connected to the driver 42 located on that side by a synchronous belt, and power can be directly transmitted to the power input member 41 by the driver 42.

[0043] As attached Figure 1 and attached Figure 3 As shown, the end of the flexible shaft body 1 is connected and fixed to the power input member 41 via a connecting mechanism 3. The axis of the entire connecting mechanism 3 coincides with the axis of the power input member 41. The connecting mechanism 3 includes a connecting flange 31, a sliding connecting member 32, a fixed connecting member 33 and a first universal joint 34.

[0044] One end of the fixed connector 33 is provided with a blind hole for accommodating and securing the end of the flexible shaft body 1, and the other end of the fixed connector 33 is fixedly connected to a power access member 41. The end of the flexible shaft body 1 that contacts the fixed connector 33 is the fixed end 6. In some other embodiments, the fixed connector 33 may also preferably be a conventional universal joint in the prior art, in which case one end of the universal joint is fixedly connected to the fixed end 6 of the flexible shaft body 1 and the other end is fixedly connected to the power access member 41 at the fixed end 6. The universal joint may adopt a cross-axis type, a ball cage type, a ball fork type, a bump type, a ball pin type, a ball hinge type, a ball hinge plunger type, a tripod type, a tripod type, a hinge rod type, or other structural forms. The universal joint can allow a certain angle difference between the fixed end 6 of the flexible shaft body 1 and the power access member 41, that is, there is a certain angle between the axis of the fixed end 6 of the flexible shaft body 1 and the axis of the power access member 41, thereby enabling the conveying device to adapt to working conditions with multiple flexible shaft bodies 1 having different degrees of bending.

[0045] The other end of the flexible shaft body 1 is connected to a corresponding sliding connection member 32 through a connecting flange 31. The end of the flexible shaft body 1 that contacts the connecting flange 31 is a sliding end 5.

[0046] The two ends of the sliding connector 32 are fixedly connected to the connecting flange 31 and the first universal joint 34, respectively. The end of the first universal joint 34 away from the sliding connector 32 is fixedly connected to the power access member 41 at the sliding end 5. The sliding connector 32 is used to change the distance between the sliding end 5 of the flexible shaft body 1 and the power access member 41 at the sliding end 5, so that the sliding end 5 of the flexible shaft body 1 can approach or move away from the power access member 41 at the sliding end 5 along the axial direction of the flexible shaft body 1, thereby compensating for the axial expansion and contraction of the flexible shaft body 1 caused by bending, and the maximum compensation amount of the sliding connector 32 is greater than the maximum axial expansion and contraction that the flexible shaft body 1 can produce.

[0047] In this embodiment, the sliding connector 32 includes a first connector 321 and a second connector 322. One end of the second connector 322 defines an axial blind hole, and the other end of the second connector 322 is fixedly connected to the power input member 41 via a first universal joint 34.

[0048] One end of the first connecting member 321 is fixedly connected to the connecting flange 31 and the other end is inserted into the blind hole of the second connecting member 322. The first connecting member 321 and the second connecting member 322 can slide axially and cannot slide circumferentially, so that the second connecting member 322 can transmit torque to the first connecting member 321 while also allowing the first connecting member 321 to slide back and forth in the blind hole along the axial direction. The setting of the first universal joint 34 at the sliding end 5 can avoid the problem of not being able to slide smoothly between the first connecting member 321 and the second connecting member 322 when there is a certain angle between the axis of the flexible shaft body 1 and the axis of the power access member 41. Thus, the connection compensation unit composed of the sliding connecting member 32 and the first universal joint 34 can meet the requirement that the sliding end 5 of the flexible shaft body 1 can still smoothly approach or move away from the power access member 41 at the sliding end 5 when bending.

[0049] Specifically, the cross-sectional shape of the first connecting member 321 can be a triangle, quadrilateral, or other non-circular polygonal or irregular shape, and the cross-sectional shape of the blind hole in the second connecting member 322 can be matched thereto. When the blind holes in the first connecting member 321 and the second connecting member 322 are both cylindrical, long key slots can be provided in the first connecting member 321 and the second connecting member 322, and a key connection can be used to ensure a sliding fit between the first connecting member 321 and the second connecting member 322.

[0050] In some other embodiments, the connection compensation unit may use a sliding universal coupling with an axial telescopic function in the prior art, and in this case, there is no need to set a sliding connection 32. The two ends of the sliding universal coupling are fixedly connected to the sliding end 5 of the flexible shaft body 1 and the power access member 41 at the sliding end 5, respectively. Since the sliding universal coupling has the function of compensating for axial displacement within a certain range, the sliding universal coupling can change the distance between the sliding end 5 of the flexible shaft body 1 and the power access member 41 at the sliding end 5. When the flexible shaft body 1 bends and axially expands and contracts, since the sliding universal coupling has both angular compensation capabilities and axial displacement compensation capabilities, it can avoid the sliding end 5 of the flexible shaft body 1 from getting stuck while compensating for the axial displacement of the flexible shaft body 1.

[0051] In order to balance and offset the deviation of the conveyed glass caused by the expansion and contraction of the multiple flexible shaft bodies 1, in this embodiment, the fixed ends 6 and the sliding ends 5 of two adjacent flexible shaft bodies 1 on the conveying device are alternately arranged.

[0052] The implementation principle of the above embodiment is:

[0053] The two driving members 42 on both sides of the conveying direction of the conveying device each drive a driving shaft 44 to rotate, and the driving shaft 44 drives all the power input members 41 on their respective sides to rotate synchronously through the power output member 45; and the synchronous rotation of the two driving members 42 can drive the power input members 41 at both ends of each flexible shaft body 1 on the conveying device to rotate synchronously, thereby achieving the synchronization of the rotation of the two ends of the flexible shaft body 1, and avoiding the skew deviation of the glass during the conveying process caused by the axial transmission delay characteristics of the flexible shaft. In addition, the axial sliding between the first connecting member 321 and the second connecting member 322 can compensate for the axial expansion and contraction of the flexible shaft body 1 when it changes between straightening and bending, thereby ensuring the stability of the conveyed glass. The setting of the connecting flange 31 makes it easy to disassemble and assemble the sliding end of the flexible shaft body 1, which is convenient for maintenance.

[0054] Example 2

[0055] This embodiment differs from the first embodiment in that both ends of the flexible shaft body 1 are fixed ends 6. Both ends of the flexible shaft body 1 are fixedly connected to the power access member 41 via fixed connectors 33. The flexible shaft body 1 in these embodiments lacks a sliding end 5 and cannot compensate for changes in the axial expansion and contraction of the flexible shaft body 1. Therefore, the flexible shaft delivery device in these embodiments is suitable for scenarios where the flexible shaft body 1 does not need to switch between a straight state and a bent state.

[0056] Example 3

[0057] As attached Figure 4 As shown, a flexible shaft conveying device disclosed in the present invention is different from the first embodiment in that two adjacent flexible shaft bodies 1 constitute a flexible shaft conveying unit. In other embodiments, multiple flexible shaft bodies 1 can also constitute a flexible shaft conveying unit.

[0058] The fixed ends 6 of all the flexible shaft bodies 1 in the same flexible shaft transmission unit are located on the same side, and the fixed ends 6 and sliding ends 5 of two adjacent flexible shaft transmission units are alternately arranged in the conveying direction of the conveying device. This arrangement is suitable for conveying longer glass, and also has the function of balancing and offsetting the deviation of the conveyed glass caused by the expansion and contraction of multiple flexible shaft bodies 1.

[0059] Although preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they are aware of the basic inventive concepts. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention. Clearly, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, to the extent such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to encompass such changes and modifications.
