Description

Technical Field

[0001] The utility model relates to the technical field of transportation equipment, in particular to a transportation line with a blocking function. Background Art

[0002] Chinese utility model patent publication number CN212711448U discloses a lifting and diverting device with a blocking function, which includes a second transport platform that is driven by a lifting mechanism to rise and fall between a high position and a low position, serving as a lifting platform. The second transport platform serves as the hub for horizontal and vertical transport. The second transport platform in the high position can be connected to the first and third transport platforms in the horizontal direction, and the second transport platform in the low position can be connected to the fourth transport platform in the vertical direction. In addition, a second baffle with a transport surface higher than the second transport platform is provided on one side of the second transport platform. The second baffle can be raised and lowered with the second transport platform, and the second baffle is away from the fourth transport platform relative to the second transport platform. Materials flowing from the fourth transport platform into the second transport platform can be blocked from the front longitudinally by the second baffle and retained on the second transport platform.

[0003] In the transport line, the transport mechanism works continuously to continuously input materials. When the previous material reaches the waiting position, if the next material is not blocked, the next material will be sent forward by the transport mechanism and collide with the previous material and / or the structure of the waiting position.

[0004] It is now hoped that the transport line will be improved by using a synchronously rising and falling blocking structure and a lifting platform to ensure that the previous material is stable in the waiting position while solving the problem of collision with the next material. Utility Model Content

[0005] The purpose of the utility model is to provide a transportation line which ensures the stability of materials to be taken and solves the problem of material collision.

[0006] The transportation line provided by the utility model includes a transportation mechanism, a lifting mechanism, a lifting platform and a blocking structure. Driven by the lifting mechanism, the lifting platform can be lifted and moved between a high position and a low position. The blocking structure is connected to the lifting platform and the two are lifted and lowered synchronously. At least a part of the blocking structure is located below the horizontal plane where the supporting surface of the lifting platform is located. The blocking structure and the lifting platform are arranged in sequence along the transportation direction of the transportation line, and the blocking structure is located upstream of the lifting platform. The transportation line includes a first position and a second position arranged in sequence along the transportation direction. The transportation mechanism extends from the first position to the second position, and the lifting platform is arranged at the second position. When the lifting platform is at a low position, the lifting platform and the blocking structure are both lower than the transportation surface of the transportation mechanism. When the lifting platform is at a high position, the lifting platform and the blocking structure are both higher than the transportation surface of the transportation mechanism, and the blocking structure prevents the material at the first position from reaching the second position.

[0007] As can be seen from the above scheme, the utility model combines the synchronously rising and falling blocking structure and the lifting platform to the second position of the transportation line, that is, the waiting position. When the current material reaches the second position, the lifting platform lifts the previous material, separates it from the transportation mechanism and stabilizes it at the current position. The blocking structure that rises synchronously with the lifting platform will block in the front of the transportation direction, preventing the next material in the first position from reaching the second position and avoiding the next material from colliding with the previous material or the structure in the second position. Among them, the blocking structure higher than the lifting platform in the background technology is used to block the material on the lifting platform. When the lifting platform rises, the blocking structure will reach a higher position and cannot block the next material at a lower position. Therefore, the utility model improves the blocking structure and sets the position of the blocking structure lower to ensure that the next material is effectively blocked.

[0008] A further solution is that the transport mechanism includes two groups of transport components arranged at intervals laterally along the transport line, and the lifting platform and the blocking structure are arranged between the two groups of transport components.

[0009] As can be seen from the above, the unused space between the two sets of transport components set at intervals is just used to arrange the jacking platform, the blocking structure and the lifting mechanism, making the transport line more compact.

[0010] A further solution is that the transport line includes two mounting frames spaced apart in a transverse direction, and the two sets of transport components are respectively mounted on the two mounting frames; the transverse distance between the two mounting frames is adjustable, and the lifting platform is detachable and replaceable.

[0011] As can be seen from the above, the adjustable lateral distance of the mounting frame and the detachable and replaceable lifting platform make the transport line suitable for transporting materials with different widths, thereby improving the applicability of the transport line to different materials.

[0012] A further solution is that a mounting frame is fixedly set up, and the transportation line also includes an adjusting motor, a screw and a screw nut. The screw extends laterally, the adjusting motor drives the screw to rotate, the screw nut is sleeved on the screw and the screw nut is connected to another mounting frame.

[0013] As can be seen from the above, this setting allows for higher precision in the lateral adjustment of the mounting frame, ie, higher precision in the adjustment of the distance between the two mounting frames and the distance between the two transport components, further improving the applicability to the transport of different materials.

[0014] A further solution is that the lifting mechanism includes lifting cylinders, the lifting cylinders are arranged on the mounting frame, and the lifting platform is connected to the ends of the piston rods of the two lifting cylinders.

[0015] As can be seen from the above, the two lifting cylinders on both sides of the lateral side respectively lift and support the jacking platform, ensuring that the jacking platform can carry materials more evenly and stably.

[0016] A further solution is that the lifting mechanism also includes two brackets arranged at intervals along the lateral direction, and the brackets are connected between the end of the piston rod of the lifting cylinder and the lifting platform. Laterally, the two brackets support the opposite sides of the lifting platform respectively; the blocking structure includes two blocking members arranged at intervals along the lateral direction, and the blocking members are connected to the brackets.

[0017] As can be seen from the above, the two blocking members can effectively intercept the material by blocking both sides of the material from the lateral sides, and this setting of the blocking members does not affect the lateral adjustment of the mounting frame, and the lateral adjustment of the mounting frame still does not affect the effectiveness of the two blocking members.

[0018] A further solution is that the lifting mechanism further includes a vertical slide rail assembly, which is connected between the mounting frame and the bracket; along the transport direction, the two vertical slide rail assemblies are respectively arranged on opposite sides of the lifting cylinder.

[0019] As can be seen from the above, since the lifting platform and the blocking member are both connected to the bracket, they extend a considerable distance in the transport direction. This arrangement requires the bracket to be longer in the transport direction. If the bracket were supported solely by the lifting cylinder, the longer bracket would likely affect its levelness due to uneven loads. It could also cause the piston rod of the lifting cylinder supporting the bracket to experience bending moments, shortening the life of the lifting cylinder. To this end, the present invention further provides vertical slide rail assemblies on opposite sides of the lifting cylinder to support the bracket, ensuring that the bracket remains horizontal and that the piston rod of the lifting cylinder withstands downward pressure, thereby extending the life of the lifting cylinder.

[0020] In another further solution, the blocking member is detachably mounted on the bracket, and / or the blocking member is mounted on the bracket in a positionally adjustable manner along the transport direction.

[0021] As can be seen from the above, under this setting, different blocking members can be replaced or the position of the blocking member in the transport direction can be adjusted according to different materials.

[0022] In another further solution, the mounting frame includes a side guard, which is arranged above the transport surface of the transport assembly, and the baffles of the two mounting frames respectively limit the materials on the transport mechanism from opposite sides in the transverse direction.

[0023] As can be seen from the above, the side ribs can limit the material to ensure that the material is transported forward stably in a straight line.

[0024] Another further solution is that the jacking platform includes a base plate and jacking columns, and the top surface of the jacking columns serves as a supporting surface; the base plate is arranged into a hollow structure; the base plate is connected to the lifting mechanism, and multiple jacking columns are arranged in an array and erected on the upper surface of the base plate; when the jacking platform is in a low position, the top surface of the jacking columns is lower than the transport surface of the transport mechanism; when the jacking platform is in a high position, the jacking columns are higher and protrude above the transport surface of the transport mechanism.

[0025] As can be seen from the above, this setting not only greatly reduces the weight of the lifting platform, but also reduces the contact area with materials such as circuit boards, avoiding damage to the materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] See also Figure 1 and Figure 2 , Figure 1 In the coordinate system, the x-axis direction represents the transport direction of the transport line of the present invention, the y-axis direction represents the horizontal direction of the transport line of the present invention, and the z-axis direction represents the vertical direction.

[0032] The transport line of this embodiment includes a first mounting frame 11, a second mounting frame 12, a transport mechanism 2, a lifting mechanism 3, a lifting platform 4, a blocking structure 5 and an adjustment mechanism 6. The first mounting frame 11 and the second mounting frame 12 are both mounting frames of the present invention; the transport mechanism 2 includes two groups of transport components 21 arranged at intervals along the transverse direction. In this embodiment, the transport components 21 are transport belt components; the lifting mechanism 3 includes two groups of components arranged opposite to each other along the transverse direction, each group of components including a lifting cylinder 31, a bracket 32 ​​and a vertical slide rail component 33, combined with the Figure 3 , and one of the components further includes a first detection unit 391, a second detection unit 392, and a third detection unit 393. The blocking structure 5 includes two blocking members 51 spaced apart in the transverse direction; the adjustment mechanism 6 includes an adjustment motor 61, a transmission belt assembly 62, a screw 63, a screw nut 64, and a transverse slide rail assembly 65.

[0033] First mounting frame 11 and second mounting frame 12 are spaced apart in the transverse direction, and two sets of transport assemblies 21 are mounted on first mounting frame 11 and second mounting frame 12, respectively. Lifting platform 4 and blocking structure 5 are positioned between the two sets of transport assemblies 21. The transport line includes a first position 101 and a second position 102, sequentially arranged along the transport direction. Transport mechanism 2 extends from first position 101 to second position 102, and lifting platform 4 is positioned at second position 102.

[0034] The first mounting frame 11 is fixed, while the second mounting frame 12 is adjustable in its lateral position along the transport line. Furthermore, a lateral sliding connection is achieved between the second mounting frame 12 and the base or site where the transport line is located via a lateral slide rail assembly 65. A screw rod 63 extends laterally, and an adjustment motor 61 drives the screw rod 63 to rotate via a transmission belt assembly 62. A screw nut 64 is mounted on the screw rod 63 and connected to the second mounting frame 12. Driven by the adjustment motor 61, the second mounting frame 12 can translate laterally toward or away from the first mounting frame 11, thereby varying the lateral distance between the first mounting frame 11 and the second mounting frame 12.

[0035] A group of lifting cylinders 31, brackets 32, vertical slide rail assemblies 33, first detection units 391, second detection units 392 and third detection units 393 are installed at the position corresponding to the second position 102 on the first mounting frame 11, and a group of lifting cylinders 31, brackets 32 and vertical slide rail assemblies 33 are installed at the position corresponding to the second position 102 on the second mounting frame 12.

[0036] Combine Figure 3 On the first mounting frame 11, the cylinder body of the vertically mounted lift cylinder 31 is fixedly connected to the first mounting frame 11. In the transport direction of the transport line, two vertical slide rail assemblies 33 are spaced apart and positioned on opposite sides of the lift cylinder 31. In the transport direction, the middle portion of the bracket 32 ​​is fixedly connected to the end of the piston rod of the lift cylinder 31, while the front and rear sides of the bracket 32 ​​are vertically slidably connected to the bracket 32 ​​via two vertical slide rail assemblies 33. The installation method of the lift cylinder 31, bracket 32, and vertical slide rail assembly 33 on the second mounting frame 12 is the same as that of the lift cylinder 31, bracket 32, and vertical slide rail assembly 33 on the first mounting frame 11.

[0037] The blocking structure 5 and the lifting platform 4 are both mounted on the bracket 32. The blocking structure 5 and the lifting platform 4 are arranged sequentially along the transport direction of the transport line, with the blocking structure 5 located upstream of the lifting platform 4. The lifting platform 4 includes a base plate 41 and lifting columns 42. The base plate 41 is configured as a hollow structure. Specifically, the base plate 41 is provided with a plurality of rectangular weight-reducing holes extending vertically therethrough, forming a hollow frame structure. The base plate 41 is connected to the lifting mechanism 3. A plurality of lifting columns 42 are arranged in a rectangular array and erected on the upper surface of the base plate 41. The top surface of the lifting columns 42 serves as the support surface for the lifting platform 4.

[0038] The two brackets 32 support the lateral sides of the bottom plate 41. The two blocking members 51 of the blocking structure 5 are each connected to a bracket 32. The blocking member 51 is provided with an elongated hole extending in the transport direction. The blocking member 51 is connected to the bracket 32 ​​via the elongated hole. In this way, the blocking member 51 is detachably mounted on the bracket 32 ​​and the blocking member 51 is mounted on the bracket 32 ​​so that its position can be adjusted along the transport direction.

[0039] Continue to see Figure 3 On the first mounting frame 11, the first detection unit 391, the second detection unit 392 and the third detection unit 393 are arranged in sequence along the transport direction of the transport line. The first detection unit 391 is arranged below the front edge of the lifting platform 4 and detects upward, the second detection unit 392 is arranged below the upstream of the rear edge of the lifting platform 4 and detects upward, and the third detection unit 393 is arranged upstream of the blocking member 51, directly below the first position 101, and detects upward.

[0040] The first detection unit 391 is used to detect whether the lifting platform 4 is installed in the correct position, the second detection unit 392 is used to detect whether the material on the lifting platform 4 has reached the correct position, and the third detection unit 393 is used to detect the material at the first position 101 and trigger the lifting cylinder 31 to drive the lifting platform 4 and the blocking structure 5 to rise.

[0041] Recombination Figure 4 and Figure 5 Driven by the lifting mechanism 3, the lifting platform 4 can be moved up and down Figure 4 The low 108 shown is Figure 5 When the lifting platform 4 is located at the low position 108 , the lifting platform 4 and the blocking structure 5 are both lower than the transport surface of the transport mechanism 2 .

[0042] When the lifting platform 4 is at the high position 109, the lifting platform 4 and the blocking structure 5 are both higher than the transport surface of the transport mechanism 2, and the blocking structure 5 prevents the material at the first position 101 from reaching the second position 102. Figure 5As shown, unlike the prior art, the blocking member 51 is entirely located below the horizontal plane (shown by the dotted line) of the top surface of the lifting column 42. This arrangement is intended to prevent the lifting platform 4 and the blocking member 51 from being located at the high position 109 when the blocking member 51 blocks the next material. If the prior art were to use a blocking member that protrudes above the lifting platform 4, the blocking member, located above the high position 109, would be unable to block the next material at the low position 108. Therefore, the present invention positions the blocking member 51 lower to effectively block the next material at the low position 108.

[0043] The utility model combines the synchronously rising and falling blocking structure 5 and the lifting platform 4 to the second position 102 of the transportation line, that is, the waiting position. When the current material reaches the second position 102 and the subsequent material reaches the first position 101, the lifting platform 4 lifts the previous material, separates it from the transportation mechanism 2 and stabilizes it at the current position. The blocking structure 5 rising synchronously with the lifting platform 4 will block in the front of the transportation direction, preventing the subsequent material in the first position 101 from reaching the second position 102, thereby avoiding the subsequent material from colliding with the previous material or the structure of the second position 102.

[0044] Furthermore, in this embodiment, the support 32 is relatively long in the transport direction, and the blocking structure 5 is mounted at the front end of the support 32, creating a significant gap in the transport direction from the lifting platform 4 near the rear end. In practice, the actual temporary placement of the preceding material in the first position 101 is determined by the position of the blocking structure 5. This arrangement ensures a sufficient gap between the first position 101 and the second position 102 in the transport direction, further ensuring sufficient distance between the material in the first position 101 and the lifting platform 4 to prevent collision.

[0045] In addition, since the blocking structure 5 and the lifting platform 4 are driven to move up and down by the same driving unit, the investment in the driving unit can be reduced, thereby lowering the cost, and the synchronization of the lifting actions of the blocking structure 5 and the lifting platform 4 can be ensured.

[0046] In other embodiments, the two mounting brackets are fixed and the lateral distance between them cannot be adjusted.

[0047] In other embodiments, the blocking structure includes a blocking member, which is in the shape of a long plate and spans across the two lateral sides of the transport line. The two lateral sides of the blocking member are respectively connected to two brackets.

[0048] In other embodiments, the transport assembly is a transport chain assembly or a transport roller assembly.

[0049] In other embodiments, a portion of the blocking structure is located below the horizontal plane where the support surface of the lifting platform is located, and another portion of the blocking structure is located above the horizontal plane where the support surface of the lifting platform is located.

[0050] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
