Description

Technical Field

[0001] The invention belongs to the technical field of round can processing equipment, and in particular relates to a round can bone finder. Background Art

[0002] When producing round metal cans, one of the steps is to use automated equipment to roll and weld tinplate sheets into a can body, followed by processing the top and / or bottom covers. During this process, after the can body is processed and transported, the can body must be uniformly aligned and positioned to ensure smooth processing in subsequent steps. Since the can body is formed by rolling tinplate sheets, the ends of the single tinplate sheet will partially overlap after rolling. The overlapping area forms the can body's skeleton. By finding this skeleton and using it as a positioning point, the can body can be uniformly aligned and positioned. In the prior art, the skeleton of the rolled can body is detected and identified through automated scanning or photography, and then aligned using a robotic arm. However, when the color of the skeleton of the rolled can body is consistent on both sides, automated scanning or photography cannot accurately locate the skeleton, which in turn leads to poor results in the subsequent processing of the can body and affects the product quality. Summary of the Invention

[0003] The purpose of the present invention is to provide a round can bone finder, which aims to solve the technical problem in the prior art that the bone position of the can body cannot be accurately found through automatic scanning or shooting.

[0004] To achieve the above-mentioned purpose, an embodiment of the present invention provides a round can bone finder, comprising:

[0005] frame;

[0006] A positioning column, wherein the positioning column is vertically installed on the frame;

[0007] A rotating disk for carrying the can body, wherein the rotating disk is provided with a magnet for magnetically attracting the can body carried thereon, and the rotating disk is arranged outside the positioning post and can rotate around the positioning post;

[0008] a power mechanism, wherein a power output end of the power mechanism is connected to the rotating disk to drive the rotating disk to rotate around the positioning post;

[0009] The spring-top mechanism is connected to the side of the positioning column and is used to abut against the inner wall of the tank body supported on the rotating disk under the action of elastic force, and blocks the bone position as the tank body rotates.

[0010] Optionally, the ejector mechanism includes a pin seat, an elastic member and a bone pin for positioning the bone position, the pin seat is connected to the positioning column, the bone pin is horizontally slidably connected to the pin seat, the elastic member is elastically connected between the pin seat and the bone pin, and always applies a force back to the pin seat on the bone pin.

[0011] Optionally, the side of the ejector seat is provided with radially arranged strip holes, the elastic member is arranged in the strip hole, the first end of the bone ejector is inserted into the strip hole and presses the elastic member, the second end of the bone ejector is exposed outside the strip hole, and the bone ejector is connected to the ejector seat by a limit member to avoid being disconnected from the ejector seat.

[0012] Optionally, the ejector seat is further provided with a locking hole perpendicular to and passing through the strip hole, and the bone ejector is provided with a waist-shaped hole arranged along its length direction, and the limiting member passes through the locking hole and the waist-shaped hole to connect the bone ejector to the ejector seat.

[0013] Optionally, a chamfered arc surface is provided on the top of the second end of the bone ejector pin exposed outside the strip-shaped hole.

[0014] Optionally, the round can bone finder further includes an anti-collision sleeve, which is connected to the top of the ejector seat, and the vertical projection of the end face of the second end of the bone position ejector is located outside the outer diameter edge of the anti-collision sleeve.

[0015] Optionally, the rotating disk includes a turntable body and a rotating column arranged on the turntable body, the rotating disk is provided with a connecting hole extending from the top of the rotating column to the bottom of the turntable body, the connecting hole is sleeved outside the positioning column, and the rotating disk is connected to the power output end of the power mechanism, and the magnet is arranged on the top of the turntable body for magnetically attracting the tank body carried on the turntable body.

[0016] Optionally, a plurality of grooves are provided on the top of the turntable body, and the magnet is embedded in each of the grooves.

[0017] Optionally, a plurality of radially evenly distributed grooves are provided on the top of the turntable body, and the magnet is embedded in each of the grooves.

[0018] Optionally, the round can bone finder further includes a positioning sleeve, which is connected to the outside of the positioning column.

[0019] The above one or more technical solutions in the round can bone finder provided by the embodiment of the present invention have at least one of the following technical effects: in the round can bone finder provided by the embodiment of the present invention, the bone position of the can body is found in the following way. When the can body is sleeved outside the positioning column and placed on the rotating disk, the can body is initially positioned under the magnetic force of the magnet provided on the rotating disk. The power generated by the power mechanism acts on the rotating disk and drives the can body to rotate. During the rotation process, the inner wall of the can body is always in contact with the end of the pop-up mechanism. Since the pop-up mechanism is connected to the positioning column and is not driven by the power mechanism, as the can body rotates, until the end of the pop-up mechanism is against the bone position on the inner wall of the can body, at this time, the can body overcomes the adsorption force of the magnet and no longer rotates with the rotating disk. When the rotating disk completes a single cycle of rotation, the can body is positioned in a position after its bone position is blocked by the pop-up mechanism. After such a process, each can body that has passed the bone position search will be uniformly positioned, and the bone position search of the can body is very accurate, thereby ensuring the production quality of subsequent processes.

[0033] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. Figures 1 to 3 The described embodiments are exemplary and are intended to be used to explain the embodiments of the present invention, but should not be construed as limiting the present invention.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0036] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0037] In one embodiment of the present invention, Figures 1 to 3As shown, a round can bone finder is provided, including a frame 10, a positioning column 20, a rotating disk 30, a power mechanism 40 and a pop-up mechanism 50, wherein the positioning column 20 is vertically installed on the frame 10; after being installed on the frame 10, the positioning column 20 is a fixed part, and can be specifically locked on the frame 10 by fasteners or other connection methods. Its purpose is to at least serve the starting stage of the execution process and realize the positioning of the initial placement position of the can body.

[0038] The rotating disk 30 is used to carry the can body, and the rotating disk 30 is provided with a magnet (not shown) for magnetically attracting the can body carried thereon. The rotating disk 30 is arranged outside the positioning column 20 and can rotate around the positioning column 20; the rotating disk 30 and the positioning column 20 are rotationally connected, that is, the rotating disk 30 can be rotated after being connected to the outside of the positioning column 20. At least one way is to achieve this by providing a bearing 100 between the rotating disk 30 and the positioning column 20.

[0039] Further, if Figure 2 As shown, the power output end of the power mechanism 40 is connected to the rotating disk 30 to drive the rotating disk 30 to rotate around the positioning column 20; after the power mechanism 40 drives the rotating disk 30, the rotating disk 30 rotates, and the rotating disk 30 rotates with the positioning column 20 as the center, thereby driving the tank body adsorbed by the magnet on the rotating disk 30 to rotate, so as to facilitate the subsequent search for the bone position on the inner wall of the tank body during the rotation process.

[0040] Furthermore, if Figure 2 As shown, the ejection mechanism 50 is connected to the side of the positioning column 20 and is used to abut the inner wall of the tank body supported on the rotating disk 30 under the action of elastic force, and achieves blocking of the bone position as the tank body rotates. The ejection mechanism 50 has a corresponding elastic force, which can always abut the inner wall of the tank body outside the positioning column 20. In this way, during the rotation of the tank body, the inner wall of the tank body will rub against the end of the ejection mechanism 50. As the tank body rotates, it will cause the bone position on the inner wall of the tank body to abut against the ejection mechanism 50. At this time, since the overall position of the ejection mechanism 50 is relatively non-rotating, the ejection mechanism 50 will prevent the tank body from continuing to rotate, overcoming the force applied by the magnet on the tank body, until the rotating disk 30 stops after rotating for one cycle. At this time, the tank body is positioned at the preset position, and the search for the tank body bone position is completed at this time.

[0041] In the round can bone finder provided by the embodiment of the present invention, the bone position of the can body is found in the following manner. When the can body is sleeved outside the positioning column 20 and placed on the rotating disk 30, the can body is initially positioned under the magnetic force of the magnet provided on the rotating disk 30. The power generated by the power mechanism 40 acts on the rotating disk 30 and drives the can body to rotate. During the rotation process, the inner wall of the can body is always in contact with the end of the pop-up mechanism 50. Since the pop-up mechanism 50 is connected to the positioning column 20 and is not driven by the power mechanism 40, as the can body rotates, until the end of the pop-up mechanism 50 is abutted against the bone position on the inner wall of the can body, at this time, the can body overcomes the adsorption force of the magnet and no longer rotates with the rotating disk 30. When the rotating disk 30 completes a single cycle of rotation, the can body is positioned at a position after its bone position is blocked by the pop-up mechanism 50. After such a process, each can body that has passed the bone position search will be uniformly positioned, and the bone position search of the can body is very accurate, thereby ensuring the production quality of subsequent processes.

[0042] In another embodiment of the present invention, Figures 2-3 As shown, the power mechanism 40 includes a motor 41 and a gear assembly 42. The output end of the motor 41 is connected to the rotating disk 30 through the gear assembly 42, thereby controlling the rotation of the rotating disk 30. For example, the gear assembly 42 can be a driving gear 421 and a driven gear 422. The driving gear 421 is connected to the output end of the motor 41, and the driven gear 422 is connected and fixed to the bottom of the rotating disk 30 and meshes with the driving gear 421. In this way, the rotation of the driving gear 421 drives the rotation of the driven gear 422, which in turn drives the rotation of the rotating disk 30. The driven gear 422 also needs to be sleeved outside the positioning column 20 and located below the rotating disk 30, and can be locked to the bottom of the rotating disk 30 by a fastener. A bearing 100 can also be provided between the driven gear 422 and the positioning column 20 to ensure that the rotation of the driven gear 422 is more stable and reliable.

[0043] Of course, in other embodiments, the power mechanism 40 may also use the cooperation of a motor and a pulley assembly to realize the rotation control of the turntable body 31 .

[0044] In one embodiment, Figures 2-3 As shown, a dual-bearing 100 arrangement is adopted, that is, the rotating disk 30 and the positioning column 20 are connected by a bearing 100, and the driven gear 422 and the positioning column 20 are connected by another bearing 100. The driven gear 422 is connected to the rotating disk 30. This ensures that the rotating disk 30 and the driven gear 422 rotate synchronously, stably and reliably.

[0045] Furthermore, if Figures 2-3As shown, the power mechanism 40 also includes a reducer 43, which is connected between the motor 41 and the driving gear 421. The setting of the reducer 43 can realize the speed change of the output speed of the motor 41, which better adapts to the search and positioning of the tank body bone position.

[0046] In another embodiment of the present invention, Figures 1 to 3 As shown, the ejector mechanism 50 includes an ejector pin seat 51, an elastic member (not shown), and a bone ejector pin 52 for positioning the bone. The ejector pin seat 51 is connected to the positioning post 20. The connection between the ejector pin seat 51 and the positioning post 20 can be achieved by a sleeve-type fixation and / or a locking method using fasteners. The bone ejector pin 52 is horizontally slidably connected to the ejector pin seat 51, thereby ensuring that the bone ejector pin 52 has a certain sliding space in the radial direction. The elastic member is elastically connected between the ejector pin seat 51 and the bone ejector pin 52 and constantly applies a force back toward the ejector pin seat 51 on the bone ejector pin 52. In this way, the bone ejector pin 52 can press against the elastic member, achieving a certain degree of sliding. Similarly, under the elastic force of the elastic member, the bone ejector pin 52 always has a tendency to extend outward. This tendency force is to ensure that the outer end of the bone ejector pin 52 is always in contact with the inner wall of the tank body when the tank body is positioned.

[0047] Wherein, the elastic member is preferably a return spring.

[0048] More specifically, the elastic force of the elastic member constantly applies pressure to the bone pin 52, causing it to constantly extend outward. Thus, when the can is positioned outside the positioning post 20, the outer end of the bone positioning pin can constantly abut against the inner wall of the can, a position achieved by the elastic member. Thus, as the can rotates with the rotating disk 30, the bone pin 52 abuts against the inner wall of the can. During rotation, the inner wall of the can generates friction with the bone pin 52 until the can rotates to the point where the bone is located and the pin 52 abuts. At this point, the rotating disk 30 continues to rotate, but the can stops. Driven by the drive mechanism, the rotating disk 30 stops after completing a single rotation cycle, completing the positioning of the can. This mechanical method of finding bone positions accurately eliminates the problems of false detection and missed detection that occur with traditional scanning or photographing methods.

[0049] In another embodiment of the present invention, Figure 2As shown, the side of the ejector seat 51 is provided with a strip hole 511 arranged in a radial direction, that is, the strip hole 511 is provided perpendicular to the positioning column 20. The elastic member is provided in the strip hole 511, the first end of the bone ejector 52 is inserted into the strip hole 511 and presses against the elastic member, the second end of the bone ejector 52 is exposed outside the strip hole 511, and the bone ejector 52 is connected to the ejector seat 51 by a limiter (not shown) to avoid being disconnected from the ejector seat 51. Specifically, the setting of the limiter can ensure that a part of the position of the bone ejector 52 can slide radially in the strip hole 511, so as to apply pressure to the elastic member or form a tendency to slide outwards under the action of the elastic force of the elastic member. The elastic member is accommodated in the strip hole 511, which also ensures that it will not fall out and can always apply elastic force to the bone ejector 52.

[0050] The limiting member may be a fastener, such as a fastener formed by a screw and a nut.

[0051] In one embodiment of the present invention, Figures 1 to 3 As shown, the limiting member can be extended into the strip hole 511, and then a strip groove is set on the side of the bone position ejector 52 to cooperate with the end of the limiting member, so that the radial sliding stroke of the bone position ejector 52 is limited to the length range of the strip groove, ensuring that the bone position ejector 52 will not fall out of the connection with the ejector seat 51.

[0052] In another embodiment of the present invention, Figure 3 As shown, the ejector seat 51 is further provided with a locking hole 512 extending perpendicularly through the strip-shaped hole 511. The bone ejector 52 is provided with a waist-shaped hole 521 arranged along its length. The limiting member passes through the locking hole 512 and the waist-shaped hole 521 to connect the bone ejector 52 to the ejector seat 51. In this embodiment, the limiting member is connected to the ejector seat 51 after passing through the locking hole 512 and the waist-shaped hole 521. The sliding travel of the bone ejector 52 is limited within the length of the waist-shaped hole 521. During the sliding process, the bone ejector 52 is blocked by the limiting member and the proximal and distal ends of the waist-shaped hole 521, thereby limiting its travel. This also ensures that the bone ejector 52 will not fall out of its connection with the ejector seat 51.

[0053] In another embodiment of the present invention, Figures 1 to 3 As shown, the top of the second end of the bone ejector pin 52 exposed outside the strip-shaped hole 511 is provided with a chamfered arc surface. The setting of the chamfered arc surface can make a softer contact with the inner wall of the tank body, and minimize the end of the bone ejector pin 52 from causing damage to the inner wall of the tank body.

[0054] In another embodiment of the present invention, the round can bone finder further includes an anti-collision sleeve 60, which is connected to the top of the ejector seat 51. This anti-collision sleeve 60 is intended to prevent contact with the can body when the can body is initially positioned outside the positioning post 20. It is secured to the top periphery of the ejector seat 51 via a sleeve connection, and is preferably made of plastic steel, which also reduces damage to the can body. Furthermore, a curved surface is preferably provided on the top periphery of the anti-collision sleeve 60 to prevent possible contact with the can body.

[0055] Among them, such as Figures 1-2 As shown, the vertical projection of the second end of the bone location ejector pin 52 is located outside the outer diameter edge of the anti-collision sleeve 60. This design ensures that during the bone location search process, the bone location ejector pin 52 contacts the inner wall of the tank body, while preventing the anti-collision sleeve 60 from contacting the inner wall of the tank body, thereby preventing the installation of the anti-collision sleeve 60 from affecting the search for the bone location in the tank body.

[0056] In another embodiment of the present invention, Figures 2-3 As shown, the rotating disk 30 includes a rotating disk body 31 and a rotating column 32 disposed on the rotating disk body 31. The outer diameter of the rotating column 32 is smaller than the outer diameter of the rotating disk body 31. The larger outer diameter of the rotating disk body 31 can effectively support the tank body, while the smaller outer diameter of the rotating column 32 can accommodate the tank body being mounted on it. The rotating disk 30 is provided with a connecting hole 311 that runs from the top of the rotating column 32 to the bottom of the rotating disk body 31. The connecting hole 311 is provided to allow the positioning rod to pass through and allows the entire rotating disk 30 to rotate around the rotating column 32. The connecting hole 311 is mounted outside the positioning column 20, and the rotating disk 30 is connected to the power output end of the power mechanism 40, wherein a bearing 100 is preferably connected between the rotating disk body 31 and the positioning column 20. Furthermore, the magnet is provided at the top of the rotating disk body 31 to magnetically attract the tank body supported on the rotating disk body 31. Specifically, the turntable body 31 and the rotating column 32 can be formed in an integral manner, which facilitates the manufacture and installation of the integral components, and the operation of the entire assembly during operation will be more stable and reliable.

[0057] In another embodiment of the present invention, Figure 1 、 3 As shown, the top of the turntable body 31 is provided with a plurality of grooves 321, each of which is embedded with a magnet. The magnet is installed in the groove 321 by embedding, which is safe and stable. The effect is better and will not cause obstruction or interference to other components.

[0058] In another embodiment of the present invention, the top of the turntable body 31 is provided with a plurality of radially evenly distributed grooves 321, each of which is embedded with a magnet. The grooves 321 designed in this way can use long strips of magnets, which can be used to locate the bone position of cans of various diameters, thus expanding the scope of application.

[0059] In another embodiment of the present invention, Figures 1 to 3 As shown, the round can bone finder also includes a positioning sleeve 70, which is connected to the outside of the positioning column 20. Furthermore, the positioning sleeve 70 can be mounted outside the rotating column 32 to achieve connection with the rotating column 32, and fasteners can be added to lock the positioning sleeve 70 and the rotating column 32 together. The positioning sleeve 70 forms a larger outer diameter after being mounted, which is as close to the inner diameter of the can body to be positioned as possible. This prevents the can body from excessively tilting or other misalignment when mounted outside the positioning column 20, thereby improving the quality of the bone finder process.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
