Description

Technical Field

[0002] In the field of machinery, it is often necessary to move objects from a low place to a high place, or from a high place to a low place. At this time, it is generally necessary to use a vertical conveying device, that is, to connect the high place and the low place through a vertical conveying device.

[0003] In the related art, a vertical conveying device generally includes a cylinder and a lifting structure. The cylinder has a conveying channel inside. The lifting structure includes a sprocket, a chain and a supporting claw. The sprocket is rotatably connected to the top and bottom of the cylinder, and the supporting claw is connected to the chain. The supporting claw fixed on the chain can lift the workpiece up and down along the conveying channel under the action of the sprocket. When the workpiece is conveyed, the workpiece is first placed in the conveying channel, and then the bottom of the workpiece is brought into contact with the supporting claw. The sprocket is then driven to rotate, and the chain can lift the supporting claw to move the workpiece. However, when the workpiece is conveyed continuously, the workpiece will generate greater inertia and impact force during the conveying process, which may cause the workpiece to collide during continuous conveying and affect the conveying.

[0031] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0032] The present disclosure provides a vertical conveying device, such as Figure 1 As shown, the vertical conveying device includes a cylinder 1, a rocker structure 2, a stop structure 3 and a connecting rod structure 4. The cylinder 1 has a transport channel 10 inside, and the side wall of the cylinder 1 has a first opening 101 and a second opening 102 arranged at intervals along the axis of the cylinder 1.

[0033] The rocker arm structure 2 is located at the first opening 101 and is connected to the outer wall of the cylinder 1. The rocker arm structure 2 is configured to move from a first state to a second state under the action of the workpiece located in the transport channel 10. In the first state, the rocker arm structure 2 is partially located in the cylinder 1, and in the second state, the rocker arm structure 2 is located outside the cylinder 1.

[0034] The stop structure 3 is located at the second opening 102 and is connected to the outer wall of the cylinder 1. The connecting rod structure 4 connects the rocker arm structure 2 and the stop structure 3, and is used to link the stop structure 3 with the rocker arm structure 2. When the rocker arm structure 2 is in the first state, the stop structure 3 is located outside the cylinder 1. When the rocker arm structure 2 is in the second state, the stop structure 3 is at least partially located inside the cylinder 1.

[0035] When the vertical conveying device provided by the embodiment of the present disclosure is used to continuously convey the workpiece, the workpiece can be conveyed through the transport channel 10 inside the cylinder 1. Since the vertical conveying device includes a rocker structure 2 and a stop structure 3, and the rocker structure 2 can be converted from a first state to a second state under the action of the workpiece, and at the same time, the stop structure 3 is linked by a connecting rod structure 4, and when the rocker structure 2 is in the first state, the stop structure 3 is located outside the cylinder 1, and when the rocker structure 2 is in the second state, the stop structure 3 is at least partially located inside the cylinder 1, so when the workpiece moves to the first opening 101, the rocker structure 2 will be converted from the first state to the second state under the action of the workpiece, and correspondingly, the rocker structure 2 will drive the stop structure 3 to move through the connecting rod structure 4, so that the stop structure 3 is at least partially located inside the cylinder 1, and the next workpiece entering the cylinder 1 is blocked to avoid collision between two adjacent workpieces being conveyed.

[0036] That is to say, the vertical conveying device provided in the embodiment of the present disclosure can not only convey the workpieces, but also stop the workpieces when they are continuously conveyed to avoid collisions between the workpieces.

[0037] Figure 2 This is a schematic diagram of the rocker arm structure provided by the embodiment of the present disclosure, combined with Figure 2Optionally, the rocker arm structure 2 includes a rocker arm bracket 21 and a rocker arm body 22. The rocker arm bracket 21 is located outside the cylinder 1 and connected to the outer wall of the cylinder 1. The rocker arm body 22 is rotatably connected to the rocker arm bracket 21, and the rotation plane of the rocker arm body 22 is parallel to the central axis of the cylinder 1. The rocker arm body 22 is rotatably connected to the connecting rod structure 4.

[0038] When the rocker arm structure 2 is in the first state, the rocker arm body 22 is at least partially located inside the cylinder 1 ; when the rocker arm structure 2 is in the second state, the rocker arm body 22 is located outside the cylinder 1 .

[0039] In the above implementation, the rocker arm structure 2 is configured as described above and can be connected to the barrel 1 via the rocker arm bracket 21, providing a mounting base for the rocker arm body 22. Furthermore, the rocker arm body 22 can rotate relative to the first opening 101 in the barrel 1, thereby engaging with the workpiece and causing rotation. Rotation of the rocker arm body 22 can also drive the connecting rod structure 4 to move along with it, thereby interlocking the rocker arm body 22 and the stop structure 3 via the connecting rod structure 4.

[0040] Optionally, a limiting hole 221 is provided on a side of the rocker arm body 22 away from the cylinder body 1 , and a length direction of the limiting hole 221 is parallel to the rotation plane of the rocker arm body 22 .

[0041] The rocker arm structure 2 further includes a first return spring 23 . A first end of the first return spring 23 is located in the limiting hole 221 , and a second end of the first return spring 23 abuts against the rocker arm bracket 21 .

[0042] In the above implementation, the limiting hole 221 is used to install the first return spring 23 to provide a mounting base for the first return spring 23 .

[0043] The first return spring 23 is used to restore the rocker arm body 22 from the second state to the first state. That is, when the rocker arm body 22 moves from the first state to the second state under the pressure of the workpiece, the first return spring 23 is compressed. After the workpiece is separated from the rocker arm body 22, the first return spring 23 can push the rocker arm body 22, allowing the rocker arm body 22 to return to the first state from the second state.

[0044] Optionally, the rocker arm structure 2 also includes a spring sleeve 24, which is sleeved on the second end of the first return spring 23, and one end of the spring sleeve 24 is located in the limiting hole 221, and the other end of the spring sleeve 24 is located outside the limiting hole 221, and is against the rocker arm bracket 21.

[0045] In the above implementation, the spring sleeve 24 is used to cooperate with the limiting hole 221 to compress the first return spring 23, allowing the rocker arm body 22 to transition from the second state to the first state under the influence of the first return spring 23. Furthermore, the spring sleeve 24 can increase the contact area between the first return spring 23 and the support 212, thereby stably compressing the first return spring 23, causing the first return spring 23 to deform and allowing the rocker arm body 22 to return from the second state to the first state.

[0046] Continue to see Figure 1 and Figure 2 Optionally, the rocker arm bracket 21 includes a column 211, a support 212 and a limiting column 213. The column 211 is arranged along the radial direction of the cylinder 1, one end is connected to the cylinder 1, and the other end is connected to the support 212. The rocker arm body 22 is rotatably connected to the support 212, and the limiting column 213 is connected to the support 212. The rotation axes of the limiting column 213 and the rocker arm body 22 are respectively located on both sides of the axis of the spring sleeve 24, and the limiting column 213 is located in the rotation plane of the rocker arm body 22.

[0047] In the above-described implementation, the rocker arm bracket 21 is configured as a column 211, a support 212, and a limiting column 213. The column 211 allows the rocker arm bracket 21 to be connected to the cylinder 1, thereby allowing the rocker arm bracket 21 to be integrally connected to the cylinder 1. Furthermore, the limiting column 213 is used to limit the rotation angle of the rocker arm body 22. When the rocker arm body 22 rotates clockwise under the action of a workpiece, from the first state to the second state, the rocker arm body 22 approaches the limiting column 213. If the rocker arm body 22 contacts the end of the limiting column 213, the rocker arm body 22 stops rotating.

[0048] For example, the limiting post 213 can be a set screw, which is secured to the support 212 via a nut. Specifically, a nut is pre-welded to the support 212, and the set screw is then secured to the support 212 by the nut. This facilitates the connection between the limiting post 213 and the support 212 and allows for adjustment of the length of the limiting post 213 between the support 212 and the rocker arm body 22, thereby adjusting the range of rotation of the rocker arm body 22.

[0049] Optionally, a side of the rocker arm body 22 close to the cylinder has an arcuate surface 222 , and a connection between the rocker arm body 22 and the rocker arm bracket 21 is located on the inner side of the arcuate surface 222 .

[0050] In the above implementation, the setting of the arc surface 222 enables the rocker arm body 22 to be quickly and completely moved out of the cylinder body 1 under the push of the workpiece, thereby preventing the rocker arm body 22 from hindering the movement of the workpiece.

[0051] For example, the rocker arm body 22 has a weight-reducing hole 223 on the inner side close to the arc surface 222. By providing the weight-reducing hole 223, the weight of the rocker arm body 22 can be greatly reduced, so that the rocker arm body 22 can rotate flexibly.

[0052] Optionally, in order to facilitate the connection between the rocker arm body 22 and the connecting rod structure 4, the rocker arm body 22 includes a main body 224 and a connecting arm 225, the main body 224 is connected to one end of the connecting arm 225, the other end of the connecting arm 225 is rotatably connected to the connecting rod structure 4, and the connection between the main body 224 and the connecting arm 225 is rotatably connected to the support 212.

[0053] Figure 3 is a schematic structural diagram of the stop structure provided by an embodiment of the present disclosure, such as Figure 3 As shown, the stop structure 3 includes a wedge block 31, a blocking rod 32 and a mounting structure 33. The blocking rod 32 is arranged along the radial direction of the cylinder 1. The first end of the blocking rod 32 is connected to the wedge block 31, and the second end of the blocking rod 32 is opposite to the second opening 102. The blocking rod 32 is installed on the cylinder 1 through the mounting structure 33. The connecting rod structure 4 cooperates with the wedge block 31 to push the blocking rod 32 to move axially.

[0054] In the above implementation, the wedge block 31 is used to cooperate with the connecting rod structure 4 to push the blocking rod 32 to move axially when the connecting rod structure 4 moves up and down along the axis of the cylinder 1, so that the blocking rod 32 can partially extend into the second opening 102.

[0055] Since the blocking rod 32 can move axially under the action of the wedge block 31, the blocking rod 32 can stop the workpiece located at the second opening 102 when it is partially inserted into the cylinder 1. The mounting structure 33 is used to connect to the cylinder 1 so that the blocking rod 32 can move relative to the second opening 102.

[0056] Optionally, the mounting structure 33 includes a second return spring 331 and a guide cylinder 332 . The guide cylinder 332 is sleeved outside the blocking rod 32 and connected to the cylinder body 1 .

[0057] The second return spring 331 is located in the guide cylinder 332 , and a first end of the second return spring 331 abuts against an inner wall of the guide cylinder 332 , and a second end of the second return spring 331 abuts against an outer wall of the blocking rod 32 .

[0058] In the above implementation, the second reset spring 331 and the guide cylinder 332 are used to reset the blocking rod 32 , that is, to enable the blocking rod 32 to move out of the cylinder body 1 from the second opening 102 .

[0059] Because the guide cylinder 332 is connected to the cylinder body 1, and the second return spring 331 abuts against the inner walls of the blocking rod 32 and the guide cylinder 332, respectively, when the blocking rod 32 is pushed by the wedge block 31 and positioned in the second opening 102, the second return spring 331 is compressed by the blocking rod 32 and the guide cylinder 332. When the rocker arm body 22 moves from the second state to the first state, the connecting rod structure 4 moves downward. At this time, the wedge block 31 no longer pushes the blocking rod 32, and the second return spring 331 causes the blocking rod 32 to withdraw from the second opening 102 and return to its original position.

[0060] Exemplarily, in order to facilitate the abutment between the second return spring 331 and the blocking rod 32 , the middle portion of the blocking rod 32 has an annular protrusion 321 , and the second end of the second return spring 331 abuts against the annular protrusion 321 .

[0061] In addition, in this embodiment, in order to prevent the blocking rod 32 from moving out of the guide cylinder 332, the guide cylinder 332 has a limiting sleeve 3321 at one end facing the wedge block 31, and the outer wall of the limiting sleeve 3321 is connected to the inner wall of the guide cylinder 332, and the inner diameter of the limiting sleeve 3321 is smaller than the outer diameter of the annular protrusion 321.

[0062] For example, in order to facilitate the connection between the limiting sleeve 3321 and the guide cylinder 332, the limiting sleeve 3321 and the guide cylinder 332 are connected by threads, that is, the outer wall of the limiting sleeve 3321 has an external thread, and the inner wall of the guide cylinder 332 has an internal thread. This facilitates the detachable connection between the limiting sleeve 3321 and the guide cylinder 332.

[0063] Optionally, the limiting sleeve 3321 is fixed in the guide cylinder 332 by threaded connection.

[0064] In addition, to facilitate the connection between the guide cylinder 332 and the cylinder body 1, the guide cylinder 332 has an outer flange 3322 at one end close to the cylinder body 1. The outer flange 3322 is provided with a screw hole, and the axis of the screw hole is parallel to the axis of the guide cylinder 332. In this way, a screw can be placed in the screw hole to connect the guide cylinder 332 to the outer wall of the cylinder body 1.

[0065] Exemplarily, the wedge block 31 includes a wedge portion 311 and a mounting portion 312. One side of the wedge portion 311 is an inclined surface 310. The mounting portion 312 is located on the other side of the wedge block 31 opposite to the inclined surface 310. The mounting portion 312 is connected to the blocking rod 32.

[0066] Optionally, the wedge-shaped portion 311 and the mounting portion 312 are connected via a pin and a cotter pin, which facilitates the detachable connection between the wedge-shaped portion 311 and the mounting portion 312.

[0067] See again Figure 1Optionally, the connecting rod structure 4 includes a first connecting rod 41 and a second connecting rod 42. The first end of the first connecting rod 41 is rotatably connected to the rocker arm body 22, the second end of the first connecting rod 41 is connected to the first end of the second connecting rod 42, and the second end of the second connecting rod 42 is transmission-connected to the wedge block 31.

[0068] In the above implementation, the first connecting rod 41 is used to be rotatably connected to the rocker arm body 22 so as to be able to move up and down when the rocker arm body 22 rotates. The second connecting rod 42 is used to be connected to the first connecting rod 41 and to cooperate with the wedge block 31.

[0069] When the rocker arm body 22 changes from the first state to the second state, the first connecting rod 41 moves upward, and the second connecting rod 42 also moves upward, which pushes the wedge block 31 and causes the wedge block 31 to move toward the cylinder 1.

[0070] For example, the first connecting rod 41 and the second connecting rod 42 form an L-shaped structure, which facilitates the connection and cooperation between the connecting rod structure 4 and the rocker arm body 22 and the stop structure 3 respectively.

[0071] Figure 4 This is a schematic diagram of the structure of the first connecting rod provided by the embodiment of the present disclosure, combined with Figure 4 Optionally, the axis direction of the first connecting rod 41 is the same as the axis direction of the cylinder 1. The first connecting rod 41 includes a first joint 411, a threaded adjustment cylinder 412, a threaded adjustment rod 413, a connecting sleeve 414 and a second joint 415 connected together in sequence.

[0072] One end of the first joint 411 is rotatably connected to the rocker arm body 22. The other end of the first joint 411 is threadedly connected to the first end of the threaded adjustment cylinder 412. The second end of the threaded adjustment cylinder 412 is threadedly connected to the first end of the threaded adjustment rod 413. The second end of the threaded adjustment rod 413 is threadedly connected to the first end of the connecting sleeve 414. The second end of the connecting sleeve 414 is threadedly connected to the first end of the second joint 415. The second end of the second joint 415 is connected to the second connecting rod 42.

[0073] In the above implementation, the length of the first connecting rod 41 can be appropriately adjusted by adjusting the length of the first joint 411 and the length of the threaded adjustment rod 413 extending into the threaded adjustment cylinder 412 .

[0074] The length variation range of the first connecting rod 41 does not exceed 30 mm, and is used to adjust the overall length of the connecting rod structure 4 and compensate for assembly errors.

[0075] See again Figure 3 Optionally, the connecting rod structure 4 further includes a roller 43 , which is connected to the second end of the second connecting rod 42 , and the outer circle of the roller 43 abuts against the inclined surface 310 of the wedge block 31 .

[0076] In the above implementation, by cooperating with the inclined surface of the roller 43 and the wedge block 31, the friction between the connecting rod structure 4 and the wedge block 31 can be greatly reduced, so that the connecting rod structure 4 can move quickly along the inclined surface of the wedge block 31, thereby quickly pushing the blocking rod 32 to move axially.

[0077] Exemplarily, the roller 43 is connected to the second connecting rod 42 via a pin and a cotter pin, wherein the pin is concentrically arranged with the roller 43. The cotter pin is plugged into the pin to prevent the pin from being separated from the roller 43 and the second connecting rod 42.

[0078] The following briefly describes the working process of the vertical conveying device provided by the embodiment of the present disclosure:

[0079] Under the action of the first return spring 23, the curved surface 222 of the rocker arm body 22 extends about 4 to 5 mm into the first opening 101 of the cylinder 1. At this time, the blocking rod 32 does not extend into the interior of the cylinder 1. The workpiece at the lower part can be transported to the middle part.

[0080] Figure 5 This is another state diagram of the vertical conveying device provided in the embodiment of the present disclosure, combined with Figure 5 When the workpiece in the cylinder 1 moves to the first opening 101, the workpiece squeezes the arcuate surface 222 of the rocker arm body 22, compresses the first return spring 23, and causes the rocker arm body 22 to rotate clockwise, and the arcuate surface 222 of the rocker arm body 22 exits the first opening 101 of the cylinder 1.

[0081] At the same time, the rocker arm body 22 drives the first connecting rod 41 and the second connecting rod 42 to move upward along the axis of the cylinder 1. The roller 43 moves upward along the inclined surface 310 of the wedge block 31. The wedge block 31 and the blocking rod 32 compress the second return spring 331, and the blocking rod 32 extends 4 to 5 mm into the interior of the cylinder 1, preventing the next workpiece from being transported upward.

[0082] The above description is merely an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the scope of protection of the present disclosure.
