Description

Technical Field

[0001] This invention relates to the field of food and pharmaceutical packaging machinery technology, specifically to a method, device, and system for rotating and positioning cylindrical objects. Background Technology

[0002] In a high-speed pre-filled syringe pen production line, the front-end material needs to be corrected before the corrected syringe pens are transferred to the assembly line of the main equipment. Chinese patent application number 202223369230.4 discloses an adaptive positioning device for syringe pens, including a mounting cylinder, a rotating part, and a limiting part. The rotating part is located at the top of the inner cavity of the mounting cylinder. The rotating part includes two symmetrically arranged abutment flanges, with inclined surfaces symmetrically arranged on both sides of the abutment flanges, and the cross-sectional area of ​​the abutment flanges increases sequentially from top to bottom. The limiting part is located in the middle of the mounting cylinder. The limiting part includes an annular flange and a limiting hole. The annular flange is connected to the abutment flange, and abutment grooves are provided on both sides of the top of the annular flange, with the abutment grooves and abutment flanges arranged alternately. The limiting hole is located on both sides of the mounting cylinder and communicates with the abutment grooves. The rotating part includes two symmetrically arranged abutment flanges. Inclined surfaces are symmetrically arranged on both sides of the abutment flanges, and the cross-sectional area of ​​the abutment flanges increases sequentially from top to bottom. This allows the injection pen to be inserted vertically into the mounting cylinder, whereby the pen's protrusion will adaptively rotate along the inclined surfaces of the abutment flanges until it rotates into the gap formed between the two abutment flanges. Then, it will slide down into the limiting part, thus completing the adjustment of the injection pen's direction and ensuring that multiple injection pens rotate to the same direction. This self-adaptive positioning device requires the injection pen to have a protrusion that can mate with the abutment flanges to achieve directional adjustment; it cannot meet the directional adjustment requirements of injection pens without protrusions. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a method, device and system for rotating and positioning cylindrical objects that meets the steering adjustment requirements of cylindrical objects without protrusions and improves the positioning accuracy.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A method for rotating and positioning a columnar object, wherein the columnar object has a signal passage portion for a signal to pass through, the method comprising the following steps: S1. The clamping and placing mechanism holding the column is rotated by the rotating mechanism so that the signal passing through the signal passage part on the column changes; S2. Record the rotation angle a1 of the column corresponding to the first preset signal received by the signal receiver, and the rotation angle a2 of the column corresponding to the second preset signal received by the signal receiver; S3. Rotate the clamping mechanism using the rotating mechanism to rotate the columnar object to the designated position between a1 and a2, thus completing the positioning.

[0005] As a further improvement to the above technical solution: The first preset signal is a signal that changes from no signal passing through the signal passage to a signal passing through the signal passage, and the second preset signal is a signal that changes from a signal passing through the signal passage to no signal passing through the signal passage, or the first preset signal is a signal that changes from a signal passing through the signal passage to no signal passing through the signal passage, and the second preset signal is a signal that changes from no signal passing through the signal passage to a signal passing through the signal passage.

[0006] A columnar object rotation positioning device is provided to implement the above-mentioned columnar object rotation positioning method. The columnar object rotation positioning device includes a support, a clamping mechanism, and a control module. The clamping mechanism is rotatably mounted on the support and is used to clamp the columnar object. The clamping mechanism is connected to a rotation mechanism. The support has a signal generator and a signal receiver on both sides of the clamping mechanism. The signal generator, signal receiver, clamping mechanism, and rotation mechanism are all electrically connected to the control module. The signal generator is used to send a signal to the signal receiver. The signal receiver is used to receive the signal passing through the signal passage during the rotation of the columnar object. The control module is used to record the rotation angle a1 of the columnar object corresponding to the first preset signal received by the signal receiver and the rotation angle a2 of the columnar object corresponding to the second preset signal received by the signal receiver, and rotates the clamping mechanism through the rotation mechanism to rotate the columnar object to a specified position between a1 and a2.

[0007] As a further improvement to the above technical solution: The clamping mechanism includes a rotating base, at least two clamping blocks, and a clamping drive. The rotating base is rotatably mounted on a support and connected to the rotating mechanism. Each clamping block is movably mounted on the top of the rotating base. The clamping drive is connected to each clamping block and is used to drive each clamping block to move closer to or away from the rotation center of the rotating base.

The annular air passage cooperates with the air inlet and is connected to the air supply mechanism. The inner wall of the clamping block is provided with a slope for pressing down on the column when clamping the column.

The support is disposed between the first conveying device and the second conveying device. The clamping and transferring device is used to transfer the columnar object on the first conveying device to the clamping and placing mechanism and to transfer the columnar object on the clamping and placing mechanism to the second conveying device.

[0011] As a further improvement to the above technical solution: The clamping and transferring device includes a support frame, a swing arm, a movable frame, a clamping mechanism, and a rotary drive mechanism. The rotary drive mechanism is mounted on the support frame. The swing arm is connected to the output shaft of the rotary drive mechanism. The movable frame is movably mounted on the support frame and rotatably connected to the swing arm. The clamping mechanism is located on the movable frame and is used to clamp and place columnar objects.

[0012] The support frame is provided with an arc-shaped slide rail, the center of which is concentric with the output shaft of the rotary drive mechanism. The swing arm is provided with a rolling element, which rolls in cooperation with the arc-shaped slide rail. The support frame is provided with a transverse guide rail, a sliding seat is slidably mounted on the transverse guide rail, and a vertical guide rail is mounted on the sliding seat. The movable frame slides in cooperation with the vertical guide rail.

[0013] The clamping mechanism is provided in two parts. When one clamping mechanism moves to the clamping and placing mechanism, the other clamping mechanism moves to the first conveying device or the second conveying device.

[0014] Compared with the prior art, the advantages of the present invention are as follows: The columnar object rotation positioning method, apparatus, and system of the present invention, on the one hand, detects signal changes (first preset signal, second preset signal) through a signal receiver as the signal passes through a signal passage area, obtains and records two reference positions (position a1 of columnar object rotation and position a2 of columnar object rotation), and then uses these two reference positions as references to rotate the columnar object to a specified position between a1 and a2, so as to realize the rotation adjustment positioning of the columnar object and meet the rotation adjustment requirements of columnar objects without protrusions; on the other hand, by detecting two signals to obtain two reference positions, and taking the value between the two reference positions as the rotation target position (specified position), compared with positioning based on a single detection signal, positioning based on two detection signals can reduce the deviation caused by signal source fluctuations and the concentration of contents in the signal passage area on the detection signal, and improve positioning accuracy.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] In the description of this invention, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this invention.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] In this invention, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0029] Example 1: Figures 1 to 3 This invention illustrates an embodiment of a columnar rotation positioning device and a columnar rotation positioning method. The columnar object 10 has a signal passage portion 101 for signal transmission. The columnar rotation positioning method includes the following steps: S1. The clamping mechanism 2 holding the column 10 is rotated by the rotating mechanism 3 so that the signal passing through the signal passage part 101 on the column 10 changes. S2. Record the rotation angle a1 of the column 10 corresponding to the first preset signal received by the signal receiver 5, and the rotation angle a2 of the column 10 corresponding to the second preset signal received by the signal receiver 5. S3. Rotate the clamping mechanism 2 by rotating the rotating mechanism 3 to rotate the column 10 to the designated position between a1 and a2, thus completing the positioning.

[0030] This columnar object rotation positioning device and its columnar object rotation positioning method, on the one hand, detects the signal changes (first preset signal and second preset signal) as the signal passes through the signal passage 101 via the signal receiver 5, obtains and records two reference positions (position a1 of columnar object 10 rotation and position a2 of columnar object 10 rotation), and then uses these two reference positions as references to rotate columnar object 10 to a specified position between a1 and a2, so as to realize the rotation adjustment positioning of columnar object 10 and meet the rotation adjustment requirements of columnar object without protrusions; on the other hand, by detecting two signals to obtain two reference positions, and taking the value between the two reference positions as the rotation target position (specified position), compared with positioning based on a single detection signal, positioning based on two detection signals can reduce the deviation caused by signal source fluctuation and the concentration of contents in the signal passage 101 on the detection signal, and improve the positioning accuracy.

[0031] Furthermore, in this embodiment, the first preset signal is a signal that changes from no signal passing through the signal passage portion 101 to a signal passing through the signal passage portion 101, and the second preset signal is a signal that changes from a signal passing through the signal passage portion 101 to no signal passing through the signal passage portion 101; or, the first preset signal is a signal that changes from a signal passing through the signal passage portion 101 to no signal passing through the signal passage portion 101, and the second preset signal is a signal that changes from no signal passing through the signal passage portion 101 to a signal passing through the signal passage portion 101. In this way, the signal passing through the signal passage portion 101 on the columnar object 10 can be changed by rotating the columnar object 10, making operation convenient. Specifically, during process S2, the first and second preset signals are generated during the unidirectional rotation (clockwise or counterclockwise) of the columnar object 10.

[0032] Furthermore, in this embodiment, the rotation angles a1 and a2 of the column 10 have the same reference A0 (a fixed reference, in the form of a straight line, serving as a fixed reference). The reference A0 passes through the center point O of the column 10, the signal passage portion 101 penetrates the column 10, the center of the signal passage portion 101 coincides with the column 10, and the front and rear edges of the end of the signal passage portion 101 in the unidirectional rotation direction of the column 10 correspond to the first preset signal corresponding position 12 and the second preset signal corresponding position 13, respectively.

[0033] When the columnar object 10 rotates relative to the reference A0 by an angle a1, a first preset signal is generated, that is, the angle between the line connecting the first preset signal position 12 and the center point O and the reference A0 is a1. When the columnar object 10 rotates relative to the reference A0 by an angle a2, a second preset signal is generated, that is, the angle between the line connecting the second preset signal position 13 and the center point O and the reference A0 is a2.

[0034] The specified position between a1 and a2 can be either a position between a1 and a2 in the clockwise direction or a position between a1 and a2 in the counterclockwise direction of column 10, and it does not necessarily have to specifically refer to the position within the shortest range in the physically meaningful rotational direction between a1 and a2. In other words, the specified position between a1 and a2 can be the position within the shortest range in the physically meaningful rotational direction between a1 and a2, such as... Figure 3 As shown, the position of (a1+a2) / 2 can also be the position outside the shortest range of the rotational direction of a1 and a2 in a physical sense, such as the position relative to (a1+a2) / 2.

[0035] Example 2: Figures 4 to 7An embodiment of the columnar object rotation positioning device of the present invention is shown. The columnar object rotation positioning device of this embodiment is used to implement the columnar object rotation positioning method of Embodiment 1. The columnar object rotation positioning device includes a support 1, a clamping mechanism 2 and a control module. The clamping mechanism 2 is rotatably mounted on the support 1 and is used to clamp the columnar object 10. The clamping mechanism 2 is connected to a rotation mechanism 3. The support 1 is provided with a signal generator 4 and a signal receiver 5 on both sides of the clamping mechanism 2. The signal generator 4, the signal receiver 5, the clamping mechanism 2 and the rotation mechanism 3 are all electrically connected to the control module. The signal generator 4 is used to send a signal to the signal receiver 5. The signal receiver 5 is used to receive the signal passing through the signal passage 101 during the rotation of the columnar object 10. The control module is used to record the rotation angle a1 of the columnar object 10 corresponding to the first preset signal received by the signal receiver 5 and the rotation angle a2 of the columnar object 10 corresponding to the second preset signal received by the signal receiver 5, and rotates the clamping mechanism 2 through the rotation mechanism 3 to rotate the columnar object 10 to a specified position between a1 and a2.

[0036] The usage process is as follows: First, the signal generator 4 sends a signal to the signal receiver 5, and the clamping mechanism 2 holding the column 10 is rotated by the rotating mechanism 3 to change the signal passing through the signal passage part 101 on the column 10; Second, the control module records the rotation angle a1 of the column 10 corresponding to the first preset signal received by the signal receiver 5, and the rotation angle a2 of the column 10 corresponding to the second preset signal received by the signal receiver 5; Third, the control module rotates the clamping mechanism 2 by the rotating mechanism 3 to rotate the column 10 to the specified position between a1 and a2, thus completing the positioning. On the one hand, the signal receiver 5 detects the signal changes (first preset signal, second preset signal) as the signal passes through the signal passage 101, obtains and records two reference positions (position a1 of the columnar object 10 and position a2 of the columnar object 10). Then, using these two reference positions as references, the columnar object 10 is rotated to a specified position between a1 and a2 to achieve the steering adjustment and positioning of the columnar object 10, meeting the steering adjustment requirements of a columnar object without protrusions. On the other hand, by detecting two signals, two reference positions are obtained, and the value between the two reference positions is taken as the rotation target position (specified position). Compared with positioning based on a single detection signal, positioning based on two detection signals can reduce the deviation caused by signal source fluctuations and the concentration of contents in the signal passage 101 on the detection signal, thereby improving the positioning accuracy.

[0037] Furthermore, in this embodiment, the first preset signal is a signal that changes from no signal passing through the signal passage portion 101 to a signal passing through the signal passage portion 101, and the second preset signal is a signal that changes from a signal passing through the signal passage portion 101 to no signal passing through the signal passage portion 101; or, the first preset signal is a signal that changes from a signal passing through the signal passage portion 101 to no signal passing through the signal passage portion 101, and the second preset signal is a signal that changes from no signal passing through the signal passage portion 101 to a signal passing through the signal passage portion 101. In this way, the signal passing through the signal passage portion 101 on the columnar object 10 can be changed by rotating the columnar object 10, making operation convenient. Specifically, during process S2, the first and second preset signals are generated during the unidirectional rotation (clockwise or counterclockwise) of the columnar object 10.

[0038] Furthermore, in this embodiment, the rotation angles a1 and a2 of the column 10 have the same reference A0 (a fixed reference, in the form of a straight line, serving as a fixed reference). The reference A0 passes through the center point O of the column 10, the signal passage portion 101 penetrates the column 10, the center of the signal passage portion 101 coincides with the column 10, and the front and rear edges of the end of the signal passage portion 101 in the unidirectional rotation direction of the column 10 correspond to the first preset signal corresponding position 12 and the second preset signal corresponding position 13, respectively.

[0039] When the columnar object 10 rotates relative to the reference A0 by an angle a1, a first preset signal is generated, that is, the angle between the line connecting the first preset signal position 12 and the center point O and the reference A0 is a1. When the columnar object 10 rotates relative to the reference A0 by an angle a2, a second preset signal is generated, that is, the angle between the line connecting the second preset signal position 13 and the center point O and the reference A0 is a2.

[0040] The specified position between a1 and a2 can be either a position between a1 and a2 in the clockwise direction or a position between a1 and a2 in the counterclockwise direction of column 10, and it does not necessarily have to specifically refer to the position within the shortest range in the physically meaningful rotational direction between a1 and a2. In other words, the specified position between a1 and a2 can be the position within the shortest range in the physically meaningful rotational direction between a1 and a2, such as... Figure 3 As shown, the position of (a1+a2) / 2 can also be the position outside the shortest range of the rotational direction of a1 and a2 in a physical sense, such as the position relative to (a1+a2) / 2.

[0041] Furthermore, such as Figures 5 to 7As shown, in this embodiment, the clamping mechanism 2 includes a rotating base 21, at least two clamping blocks 22, and a clamping drive 23. The rotating base 21 is rotatably mounted on the support 1 and connected to the rotating mechanism 3. Each clamping block 22 is movably mounted on the top of the rotating base 21. The clamping drive 23 is connected to each clamping block 22 and is used to drive each clamping block 22 to move closer to and away from the rotation center of the rotating base 21. The clamping drive 23 drives each clamping block 22 to move closer to the rotation center of the rotating base 21 to clamp the columnar object 10, and drives each clamping block 22 to move away from the rotation center of the rotating base 21 to release the columnar object 10. When the columnar object 10 is clamped by each clamping block 22, the center of the columnar object 10 coincides with the rotation center of the rotating base 21.

[0042] Further, in this embodiment, the clamping drive 23 is a gripping cylinder that rotatably engages with the bracket 1. The clamping drive 23 is located at the bottom of the rotating seat 21 and rotatably engages with the bracket 1. An air inlet 231 is provided on the side of the clamping drive 23. The bracket 1 has an annular air passage surrounding the clamping drive 23, which engages with the air inlet 231 and is connected to the air supply mechanism. The inner wall of the clamping block 22 has a slope 221 for pressing down on the columnar object 10 when clamping it. The bracket 1, through the engagement of the annular air passage and the air inlet 231, ensures that the airflow and the rotational movement of the clamping drive 23 do not interfere with each other. Figure 6 As shown, the inner wall of the clamping block 22 is provided with a slope 221 for pressing down on the column 10 when clamping it, thereby improving the stability of the clamping. Generally, the bottom of the column 10 has a circumferentially outwardly convex portion, and the slope 221 is used to press down on the outwardly convex portion when clamping the column 10.

[0043] Furthermore, in this embodiment, multiple clamping mechanisms 2 are provided and arranged side by side along the length of the support 1. In this way, multiple columnar objects 10 can be turned, adjusted, and positioned at one time, improving production efficiency.

[0044] Example 3: Figure 8 and Figure 9 An embodiment of the columnar object rotation positioning device of the present invention is shown. The columnar object rotation positioning system of this embodiment includes a first conveying device 6, a second conveying device 7, a clamping and transferring device 8, and the columnar object rotation positioning device of Embodiment 2. The bracket 1 is disposed between the first conveying device 6 and the second conveying device 7. The clamping and transferring device 8 is used to transfer the columnar object 10 on the first conveying device 6 to the clamping and placing mechanism 2 and to transfer the columnar object 10 on the clamping and placing mechanism 2 to the second conveying device 7.

[0045] The first conveying device 6 conveys the columnar objects 10 in rows to the corresponding positions of the clamping and transferring device 8. The clamping and transferring device 8 then transfers the columnar objects 10 from the first conveying device 6 to each clamping mechanism 2. Each columnar object 10 is rotated and positioned by each clamping mechanism 2 to a designated position with the same orientation. The clamping and transferring device 8 then transfers the columnar objects 10 from each clamping mechanism 2 to the second conveying device 7. Finally, the second conveying device 7 conveys the columnar objects 10 with the same orientation to the next workstation.

[0046] Furthermore, such as Figure 9 As shown, in this embodiment, the clamping and transferring device 8 includes a support frame 81, a swing rod 82, a movable frame 83, a clamping mechanism 84, and a rotary drive mechanism 85. The rotary drive mechanism 85 is mounted on the support frame 81. The swing rod 82 is connected to the output shaft of the rotary drive mechanism 85. The movable frame 83 is movably mounted on the support frame 81 and rotatably connected to the swing rod 82. The clamping mechanism 84 is mounted on the movable frame 83 and is used to clamp and release the cylindrical object 10. The rotary drive mechanism 85 drives the swing rod 82 to swing, and the swing rod 82 drives the movable frame 83 to move between the clamping station and the release station. The clamping mechanism 84 moves with the movable frame 83 between the clamping station and the release station, thereby clamping the cylindrical object 10 at the clamping station and releasing the cylindrical object 10 at the release station.

[0047] Furthermore, in this embodiment, the support frame 81 is provided with an arc-shaped slide rail 811, the center of which is concentric with the output shaft of the rotary drive mechanism 85. The swing arm 82 is provided with a rolling element that rolls in cooperation with the arc-shaped slide rail 811. A transverse guide rail 11 is provided on the support frame 81, and a sliding seat 9 slides on the transverse guide rail 11. A vertical guide rail 91 is provided on the sliding seat 9, and the movable frame 83 slides in cooperation with the vertical guide rail 91. Thus, the rotation and swing of the swing arm 82 can drive the movable frame 83 and the clamping mechanism 84 to move horizontally and vertically, satisfying the movement requirements of the cylindrical object 10 transferred between the clamping station and the release station.

[0048] Furthermore, in this embodiment, two clamping mechanisms 84 are provided. When one clamping mechanism 84 moves to the clamping and placing mechanism 2, the other clamping mechanism 84 moves to the first conveying device 6 or the second conveying device 7. In this way, the transfer between the first conveying device 6 and the clamping and placing mechanism 2, and between the clamping and placing mechanism 2 and the second conveying device 7, can be carried out simultaneously, improving the transfer efficiency and thus improving the production efficiency.

Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention.
