Description

Technical Field

[0001] The utility model relates to the field of filling bottle conveying, in particular to a bottle clamping and conveying device. Background Art

[0002] The rotary bottle clamping and conveying device includes a bottle clamp that is located on a circular motion path and performs unidirectional rotational motion, and a cam for driving the bottle clamp to open and close. The cam has guide surfaces distributed around the circular motion path of the bottle clamp. The end of one of the clamp arms of the bottle clamp is provided with a roller corresponding to the guide surface. The roller and the guide surface are in contact with each other. During the rotational motion of the bottle clamp, the roller moves along the guide surface, causing the clamp arm to swing, and then the entire bottle clamp to open and close.

[0003] For example, in the patent application "A Bottle-Grabbing Manipulator for a Vertical Rotary Bottle Washing Machine," published in Chinese Patent Publication No. CN213796471U, a roller is provided at one end of the active clamping arm, and a bumper is provided between the clamping arm seat and the rotating turntable. The outer edge of the bumper abuts against the roller, thereby controlling the opening and closing of the active and passive clamping arms. However, the roller and the active clamping arm are located on the same plane, and the bumper is located on the inner side of the clamping arm. In order to arrange the bumper and abut the bumper against the roller to control the opening and closing of the clamping arm, the rotation radius of the entire device is relatively large.

[0008] In the above-mentioned bottle clamping and conveying device, a connecting piece is further provided on the turntable assembly between the first clamp body and the second clamp body, and an end portion of the connecting piece is provided with a rotation-stopping portion extending into the bottle neck clamping portion.

[0009] In the above-mentioned bottle clamping and conveying device, the first clamping mouth and the second clamping mouth are both provided with abutment parts that are in point contact or line contact with the bottleneck, and the projections of the two abutment parts and the anti-rotation part in a plane perpendicular to the axis of the bottle mouth are distributed on the three vertices of a triangle.

[0010] In the above-mentioned bottle-gripping conveying device, the return assembly includes a return spring, the lower end of the second connecting rod passes through the turntable assembly and is connected to one end of the return spring, and the other end of the return spring is connected to the turntable assembly.

[0011] In the above-mentioned bottle-gripping and conveying device, the first connecting rod and the second connecting rod are connected via a pair of meshing gears to achieve synchronous reverse movement of the first connecting rod and the second connecting rod.

[0012] In the above-mentioned bottle clamping and conveying device, the rotary triggering member includes a triggering body rotatably connected to the first clamp body and a fixing member fixedly connected to the first clamp body, and an elastic buffer member is provided between the triggering body and the fixing member.

[0013] In the above-mentioned bottle clamping and conveying device, the turntable assembly includes a power disk and a first mounting disk axially spaced apart from the power disk, the power disk is rotatably connected to the lower parts of the first and second connecting rods, and the first mounting disk is rotatably connected to the upper parts of the first and second connecting rods.

[0014] In the above bottle clamping and conveying device, the turntable assembly further includes a second mounting plate disposed between the power plate and the first mounting plate, and the second mounting plate is rotatably connected to the middle portion of the first connecting rod and the middle portion of the second connecting rod.

[0015] In the above-mentioned bottle clamping and conveying device, the second mounting plate and the power plate are fixedly connected.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] By arranging the first clamp body and the rotating trigger member at the two ends of the first connecting rod respectively, the problem of the large rotation radius of the current rotary bottle clamping robot is solved. The first clamp body is connected by the first connecting rod, and the second clamp body is connected by the second connecting rod. The first connecting rod and the second connecting rod are synchronously rotated in opposite directions. After the rotating trigger member on the first connecting rod is triggered by the trigger body, it drives the first connecting rod to rotate while the second connecting rod rotates in the opposite direction, which can control the opening or closing of the first clamp body and the second clamp body, thereby releasing or clamping the bottle; after the rotating trigger member is separated from the trigger body, the return assembly drives the second connecting rod to rotate, and the second connecting rod rotates while the first connecting rod rotates in the opposite direction, thereby closing or opening the first clamp body and the second clamp body, and then returning the first clamp body and the second clamp body to their initial state. The first clamp body is located at the top end of the first connecting rod, the rotary trigger member is located at the bottom end of the first connecting rod, and the first clamp body and the rotary trigger member are arranged on both sides of the turntable assembly. The original arrangement of the rotary trigger member and the clamp body in the rotating plane is changed to an interval arrangement in the direction perpendicular to the rotating plane. The clamp body can be closer to the center of the turntable assembly, reducing the rotation radius of the bottle clamp assembly and the radial space occupied by the entire device in the turntable assembly. In addition, the axial space of the turntable assembly is fully utilized, so that the arrangement of the rotary trigger member is not affected by the clamp body.

[0018] Furthermore, a first latch is provided on the front of the first caliper body, and a second latch is provided on the front of the second caliper body, and the first and second latches form a bottleneck latch. The latches are provided on each of the two caliper bodies, and when the two caliper bodies are closed, the bottleneck latch has as much contact surface as possible with the bottleneck, thereby clamping the bottleneck more firmly.

[0019] Furthermore, a connecting member is provided on the turntable assembly between the first and second clamp bodies, and an end of the connecting member is provided with a rotation-stopping portion that extends into the neck of the bottle. The rotation-stopping portion that extends into the neck of the bottle abuts against the bottle neck, thereby preventing the bottle from rotating when the bottle cap is screwed on, thereby allowing the bottle cap to be tightened on the bottle.

[0020] Furthermore, the first and second clamping ports are each provided with abutment portions that provide point or line contact with the bottle neck. The projections of the two abutment portions and the anti-rotation portion in a plane perpendicular to the axis of the bottle mouth are distributed at the three vertices of a triangle. This three-point abutment provides a more secure grip on the bottle, preventing the bottle from rotating about its own axis.

[0021] Furthermore, the return assembly includes a return spring. The lower end of the second connecting rod passes through the turntable assembly and is connected to one end of the return spring, while the other end of the return spring is connected to the turntable assembly. When the second connecting rod is rotated by the first connecting rod, the return spring accumulates elastic potential energy. When the first connecting rod loses its force on the second connecting rod, the return spring causes the second connecting rod to drive the first connecting rod back to its initial position. The return spring has a simple structure and reliable performance, and can frequently and repeatedly return the second connecting rod.

[0022] Furthermore, the first connecting rod and the second connecting rod are connected by a pair of meshing gears to achieve synchronous and opposite movement of the first and second connecting rods. The meshing gears can achieve synchronous and opposite movement of the first and second connecting rods, and the power transmission is smooth, so that the first connecting rod can drive the second connecting rod to rotate, and the second connecting rod can also drive the first connecting rod to rotate.

[0023] Furthermore, the rotary trigger member includes a trigger body rotatably connected to the first caliper body and a fixing member fixedly connected to the first caliper body, with an elastic buffer member disposed between the trigger body and the fixing member. The elastic buffer member reduces the impact on the first connecting rod when the trigger body is triggered, and also reduces the impact on the synchronously rotating connection between the first connecting rod and the second connecting rod.

[0024] Furthermore, the turntable assembly includes a power disk and a first mounting disk axially spaced apart from the power disk. The power disk is rotatably connected to the lower portions of the first and second connecting rods, and the first mounting disk is rotatably connected to the upper portions of the first and second connecting rods. The power disk and the first mounting disk respectively limit the ends of the first and second connecting rods, ensuring that the first and second connecting rods rotate smoothly and are not easily shaken after clamping a bottle.

[0025] Furthermore, the turntable assembly further includes a second mounting plate disposed between the power plate and the first mounting plate, the second mounting plate being rotatably connected to the middle portion of the first connecting rod and the middle portion of the second connecting rod. The addition of the second mounting plate further stabilizes the first and second connecting rods, ensuring that the turntable assembly does not wobble during operation.

[0026] Furthermore, the second mounting plate is fixedly connected to the power plate, thereby fixing the second mounting plate and the power plate together to increase the stability of the two. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] A bottle clamping and conveying device includes a turntable assembly 100 and a plurality of bottle clamping assemblies 200 arranged at intervals along the circumference of the turntable assembly 100, wherein the bottle clamping assembly 200 includes a first clamp body 210, a second clamp body 220, a first connecting rod 230 and a second connecting rod 240, wherein the first connecting rod 230 and the second connecting rod 240 are both rotatably connected to the turntable assembly 100, and the first connecting rod 230 and the second connecting rod 240 are synchronously and reversely driven. The top of the first connecting rod 230 passes through the turntable assembly 100 and is fixedly connected to the first clamp body 210, the top of the second connecting rod 240 passes through the turntable assembly 100 and is fixedly connected to the second clamp body 220, a return assembly 250 is provided between the second connecting rod 240 and the turntable assembly 100, the bottom of the first connecting rod 230 passes through the turntable assembly 100 and is connected to a rotation trigger member 260, and a trigger body for pushing the rotation trigger member 260 to rotate is provided on the motion trajectory of the rotation trigger member 260.

[0037] By arranging the first clamp body 210 and the rotation trigger member 260 at both ends of the first connecting rod 230 respectively, the problem of a large rotation radius of the current rotary bottle clamping robot is solved. The first connecting rod 230 is connected to the first clamp body 210, and the second connecting rod 240 is connected to the second clamp body 220. The first connecting rod 230 and the second connecting rod 240 are synchronously connected for reverse rotation. After the rotary trigger member 260 on the first connecting rod 230 contacts the trigger body, the trigger body pushes the rotary trigger member 260 to rotate. The rotary trigger member 260 drives the first connecting rod 230 to rotate while the second connecting rod 240 rotates in the opposite direction, thereby controlling the first clamp body 210 and the second clamp body 220 to open or close, thereby releasing or clamping the bottle; after the rotary trigger member 260 is separated from the trigger body, the return assembly 250 drives the second connecting rod 240 to rotate. The second connecting rod 240 rotates while the first connecting rod 230 rotates in the opposite direction, thereby closing or opening the first clamp body 210 and the second clamp body 220, and then returning the first clamp body 210 and the second clamp body 220 to their initial state. The first clamp body 210 is located at the top end of the first connecting rod 230, and the rotary trigger member 260 is located at the bottom end of the first connecting rod 230. The first clamp body 210 and the rotary trigger member 260 are arranged on both sides of the turntable assembly 100. The original arrangement of the rotary trigger member 260 and the clamp body in the rotation plane is changed to an axially spaced arrangement. The clamp body can be closer to the center of the turntable assembly 100, reducing the rotation radius of the bottle clamp assembly 200 and reducing the radial space occupied by the entire device in the turntable assembly 100. In addition, the axial space of the turntable assembly 100 is fully utilized, so that the arrangement of the rotary trigger member 260 is not affected by the clamp body.

[0038] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0039] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0040] 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 the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0041] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0042] See Figures 1 to 6 This is an embodiment of a bottle clamping and conveying device of the present invention, which includes a turntable assembly 100 and a plurality of bottle clamping assemblies 200 arranged axially at intervals along the turntable assembly 100. The turntable assembly 100 is used to support the bottle clamping assemblies 200 and drive the bottle clamping assemblies 200 to rotate circumferentially.

[0043] The bottle clamp assembly 200 includes a first clamp body 210, a second clamp body 220, a first connecting rod 230, and a second connecting rod 240. The first connecting rod 230 and the second connecting rod 240 both penetrate the turntable assembly 100 and are rotatably connected to the turntable assembly 100. That is, the first connecting rod 230 and the second connecting rod 240 can each rotate about their own axis relative to the turntable assembly 100. The top end of the first connecting rod 230 is located above the turntable assembly 100 and is fixedly connected to the first clamp body 210. The bottom end of the first connecting rod 230 is located below the turntable assembly 100 and is connected to a rotating trigger 260. A trigger is provided on the running track of the rotating trigger 260. The trigger can adopt a structure known in the art, such as a cam or a trigger surface. When the rotating trigger 260 moves into contact with the cam or the trigger surface, it pushes the rotating trigger 260 to rotate a certain angle about the axis of the first connecting rod 230, thereby driving the first clamp body 210 to rotate about the axis of the first connecting rod 230. The top end of the second connecting rod 240 is located above the turntable assembly 100 and is fixedly connected to the second pliers 220. The first pliers 210 and the second pliers 220 are located in the same horizontal plane. The first connecting rod 230 and the second connecting rod 240 rotate synchronously in opposite directions. That is, when the rotating trigger 260 drives the first connecting rod 230 to rotate clockwise around the axis, the second connecting rod 240 simultaneously drives the second pliers 220 to rotate counterclockwise around the axis of the second connecting rod 240. This realizes the opening and closing of the first pliers 210 and the second pliers 220.

[0044] Through the above structure, the original structure in which the rotary trigger member 260 and the first clamp body 210 and the second clamp body 220 are on the same horizontal plane is changed to a structure in which the rotary trigger member 260 and the first clamp body 210 and the second clamp body 220 are at both ends of the connecting rod, so that the first clamp body 210 and the second clamp body 220 can be closer to the center of the turntable assembly 100, the rotation radius of the first clamp body 210 and the second clamp body 220 will be smaller, and the radial dimension of the turntable assembly 100 occupied by the entire structure will be reduced. Since the first clamp body 210 and the second clamp body 220 generally clamp the bottleneck of the bottle, the bottle itself also occupies a certain height space. In order to make full use of the height space occupied by the bottle, the rotary trigger member 260 is set below the first clamp body 210 to improve space utilization.

[0045] Furthermore, the rear portion of the first clamp body 210 is fixedly connected to the top of the first connecting rod 230, the front portion of the first clamp body 210 is provided with a first bayonet 211, the rear portion of the second clamp body 220 is fixedly connected to the top of the second connecting rod 240, and the front portion of the second clamp body 220 is provided with a second bayonet 221. The opening directions of the first bayonet 211 and the second bayonet 221 are opposite. After the first clamp body 210 and the second clamp body 220 are closed, the first bayonet 211 and the second bayonet 221 form a bottleneck bayonet, which will adapt to and clamp the bottleneck of the bottle, driving the bottle to rotate circumferentially along the turntable assembly 100. This design allows the bottleneck bayonet to be spliced ​​into a circle as much as possible, increasing the contact area with the bottleneck and driving the bottle to rotate more stably.

[0046] Furthermore, a connecting piece 270 is fixed to the turntable assembly 100 between the first clamp body 210 and the second clamp body 220. The connecting piece 270 can be fixed to the turntable assembly 100 by means of plugging, clamping or bolting, and the head of the connecting piece 270 is facing the direction of the bottleneck bayonet, and the head of the connecting piece 270 is provided with a rotation-stop portion 271 extending into the bottleneck bayonet. The rotation-stop portion 271 can be tooth-shaped, or it can be a convex point or other shape. When the bottleneck bayonet clamps the bottleneck, the rotation-stop portion 271 will squeeze the bottleneck, and a large friction force is formed between the rotation-stop portion 271 and the bottleneck. When the bottle cap is screwed onto the bottle, the rotation-stop portion 271 will prevent the bottle from rotating along its circumferential direction, so that the bottle cap can be installed in place.

[0047] Furthermore, the contact area between the anti-rotation portion 271 and the bottleneck is too small and may not generate sufficient friction to prevent the bottle from rotating during the capping process. In this case, an abutment portion 212 may be provided in the first bayonet 211 and the second bayonet 221. The abutment portion 212 is in point contact or line contact with the bottleneck so as to generate sufficient squeezing with the bottleneck. The projections of the two abutment portions 212 and the anti-rotation portion 271 in a plane perpendicular to the axis of the bottle mouth are distributed on the three vertices of the triangle, so that the friction force preventing the bottle from rotating can be more evenly distributed.

[0048] On the basis of the above embodiment, the return assembly 250 includes a return spring, the lower end of the second connecting rod 240 passes through the turntable assembly 100 and is connected to one end of the return spring, and the other end of the return spring is connected to the turntable assembly 100. Specifically, the first connecting member 270 can be fixed at the lower end of the second connecting rod 240, and the second connecting member 270 can be fixed on the turntable assembly 100. The two ends of the return spring are respectively fixed on the first connecting member 270 and the second connecting member 270. The fixing point of the return spring and the first connecting member 270 can be a certain distance away from the axis of the second connecting rod 240. In this way, when the second connecting member 270 is driven to rotate by the first connecting member 270, the return spring can be driven to generate sufficient elastic potential energy. When the external force applied to the rotating trigger member 260 on the first connecting member 270 is removed, the return spring can release the elastic potential energy, driving the second connecting member 270 to rotate in the opposite direction, and also causing the first connecting member 270 to rotate in the opposite direction, allowing the first clamp body 210 and the second clamp body 220 to return to their initial positions.

[0049] In order to achieve the synchronous reverse movement of the first link 230 and the second link 240, the first link 230 and the second link 240 are transmitted through a pair of meshing gears 280, that is, a gear is fixed on the first link 230 and the second link 240 respectively. When the two gears are meshed, the first link 230 can drive the second link 240 to rotate in the opposite direction, and the second link 240 can also drive the first link 230 to rotate in the opposite direction. The gear meshing transmission is smooth and reliable, which can ensure the relatively stable reverse rotation of the first link 230 and the second link 240, thereby realizing the opening and closing of the first clamp body 210 and the second clamp body 220.

[0050] When the rotating trigger member 260 is subjected to an external force, it is prone to sudden impact, which may cause the first caliper body 210 to collide with the second caliper body 220, or impact the gears between the first connecting rod 230 and the second connecting rod 240. To avoid such situations, the rotating trigger member 260 includes a trigger body 261 rotatably connected to the first caliper body 210 and a fixing member 262 fixedly connected to the first caliper body 210. An elastic buffer member 263 is provided between the trigger body 261 and the fixing member 262. The trigger body 261 can be a roller to achieve rolling contact with the cam or trigger surface. The trigger body 261 is as far away from the axis of the first connecting rod 230 as possible to generate sufficient torque to rotate the first connecting rod 230. The elastic buffer member 263 can be a component with a buffering effect such as a compression spring or a spring. When the trigger body 261 is subjected to an external force, it will first squeeze the elastic buffer member 263, allowing it to absorb the impact. However, the elastic buffer member 263 must also have a certain degree of rigidity to transmit power.

[0051] Based on the above embodiment, the turntable assembly 100 is required to stabilize the bottle clamp assembly 200 and drive it to rotate circumferentially. The turntable assembly 100 includes a power disk 110 and a first mounting disk 120 spaced axially from the power disk 110. The power disk 110 stabilizes the lower portions of the first connecting rod 230 and the second connecting rod 240, while the first mounting disk 120 stabilizes the upper portions of the first connecting rod 230 and the second connecting rod 240. A plurality of rotating holes can be provided on the power disk 110 and the first mounting disk 120 to allow the first connecting rod 230 and the second connecting rod 240 to pass through. The peripheral wall of the power disk 110 is provided with teeth that mesh with matching gears to achieve power transmission, driving the bottle clamp assembly 200 to rotate circumferentially.

[0052] Furthermore, the turntable assembly 100 further includes a second mounting plate 130 disposed between the power disc 110 and the first mounting plate 120. The second mounting plate 130 is rotatably connected to the middle portion of the first connecting rod 230 and the middle portion of the second connecting rod 240, thereby stabilizing the middle portions of the first connecting rod 230 and the second connecting rod 240. The second mounting plate 130 can also be fixedly connected to the power disc 110, so that the second mounting plate 130 and the power disc 110 form a relatively stable base.

[0053] Multiple groups of bottle clamp assemblies 200 are arranged along the circumference of the turntable assembly 100. The turntable assembly 100 drives the bottle clamp assemblies 200 to rotate along the circumference of the turntable assembly 100. When the rotary trigger member 260 located below the bottle clamp assembly 200 contacts the cam or trigger surface provided on its running track, the cam or trigger surface will push the rotary trigger member 260 to drive the first connecting rod 230 to rotate about the axis of the first connecting rod 230. When the first connecting rod 230 rotates, the meshing gear 280 drives the second connecting rod 240 to rotate in the opposite direction about the axis of the second connecting rod 240, thereby closing the first clamp body 210 and the second clamp body 220. After the rotary trigger member 260 is offset from the cam or trigger surface, under the action of the return assembly 250, the second connecting rod 240 rotates in the opposite direction along its axis and simultaneously drives the first connecting rod 230 to rotate in the opposite direction along its own axis, thereby opening the first clamp body 210 and the second clamp body 220. Since the rotary trigger member 260 is located at the bottom end of the first connecting rod 230 and the first clamp body 210 is located at the top end of the first connecting rod 230, the rotary trigger member 260 does not obstruct the first clamp body 210 in the radial direction of the turntable assembly 100, so that the first clamp body 210 can be closer to the center of the turntable assembly 100, so that the space occupied by the entire bottle clamping and conveying device in the radial direction of the turntable assembly 100 is reduced, and the entire device is more compact.

[0054] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in this field within the scope of the present invention are included in the patent scope of the present invention.
