Description

Technical Field

[0001] The utility model relates to the technical field of transfer of barreled products, in particular to a transfer device. Background Art

[0002] On the production line of barrel or bottled products, after filling, capping and labeling, they are transported to the packing station. At the packing station, they can be packed manually. For larger barrel products, it is the manufacturer's wish to use extraction equipment to complete the packing operation.

[0003] The technical solution disclosed in the name of "A Bottle Cap Opening Clamp" (publication number CN215667060U, hereinafter referred to as Document 1) requires the use of a bottle body grasping fixture 3 to place the barrel or bottle (hereinafter referred to as the barrel) containing the product and place it on the bottle body fixing fixture. The bottle body fixing fixture constrains the concave waist part of the bottle body, and then the bottle cap opening fixture 4 performs the bottle opening operation. In order to realize the action of extracting and transporting the bottle body, the solution provided in Document 1 is that a video recognition target capture mechanism identifies the bottle in the bottle storage place and sends it to the PLC. The PLC controls the opening of the intelligent force-controlled electric clamp 2, the lifting mechanism 1 descends to a pre-set height, the force arm is tightened, the bottle body grasping fixture 3 clamps the bottle neck, and the lifting mechanism rises to complete the clamping of the bottle. The extraction scheme provided in Document 1 mainly has the following defects: First, the bottle body grasping fixture 3 does not limit its specific movement trajectory, which is feasible for the basic purpose of opening the bottle cap to be achieved in Document 1, because the operation of opening the bottle cap is usually the opening of a single bottle cap, that is, the scheme provided in Document 1 is suitable for the extraction and transportation of a single bottle. Naturally, if multiple bottle caps need to be opened at the same time, that is, the bottle body grasping fixture 3 needs to extract and transport multiple bottles at the same time, there will be mutual interference between the multiple bottle body grasping fixtures 3; second, the precise positional relationship between the bottle body grasping fixture 3 and the bottle body in Document 1 depends on PLC control, otherwise it is difficult to ensure the accurate alignment of the bottle body grasping fixture 3 with the bottleneck of the bottle body. Utility Model Content

[0004] The utility model aims to provide a transfer device, which can ensure that the barrel neck clamp is reliably and accurately clamped at the barrel neck when there is a position error between the restraining area provided by the barrel neck clamp and the barrel neck.

[0005] The utility model can be realized by the following technical scheme: a transfer device, a movable seat and a movable platform that move horizontally along a horizontally arranged guide rail form a vertical relative displacement match, the lower part of the movable platform is connected to a clamping mechanism, the clamping mechanism includes a support, the upper plate edges of guide plates arranged in an eight-shaped shape are fixed on the support, the horizontal distance between the plate surfaces on the opposite sides of the two guide plates gradually increases from top to bottom, the upper end of the swing arm is hinged on the support, and the swing surfaces of the two swing arms are A common vertical plane is formed, and the two guide plates are symmetrically distributed on both sides of the swing surface of the swing arm. The vertical plane of the mirror symmetry plane of the guide plate is orthogonal to the swing surface of the swing arm as a whole. An arc-shaped clamp is connected to the lower end of the swing arm. The arc range of the arc-shaped clamp is smaller than a semicircle. When the swing arm swings to the point where the arc-shaped clamp approaches the barrel neck, the clamping openings of the two arc-shaped clamps are relatively clamped on the barrel neck at the lower edge of the barrel mouth convex ring. When the swing arm swings to the point where the arc-shaped clamp is away from the barrel neck, the opening between the clamping openings of the two arc-shaped clamps is larger than the diameter of the barrel mouth convex ring.

[0006] Compared with the prior art, the utility model has the following beneficial effects:

[0007] When there is an error in the position between the constraint area provided by the two arc-shaped clips and the barrel neck, as the two guide plates approach the barrel body, one guide plate will first contact the barrel shoulder on one side of the barrel body, and push the barrel body toward the direction close to the other guide plate, so that the two guide plates contact the barrel shoulder at the same time, ensuring that the position of the barrel body is exactly located in the constraint area provided by the two arc-shaped clips. At this time, the two swing arms swing toward the barrel cover at the same time. Due to the constraints provided by the two arc-shaped clips when they swing close to each other, the barrel body is driven to move toward the symmetrical center position of the two arc-shaped clips. When the swing arms swing until the arc-shaped clips are close to the barrel neck, the clip mouths of the two arc-shaped clips are relatively clamped on the barrel neck at the lower edge of the barrel mouth convex ring, thereby ensuring that when there is an error in the position between the constraint area provided by the two arc-shaped clips and the barrel neck, the two arc-shaped clips can be reliably and accurately clamped on the barrel neck.

[0015] like Figure 1 As shown, the barrel mouth section of the barrel body A is provided with a barrel cover B, and the barrel mouth section of the barrel body A is provided with a barrel mouth convex ring A1 below the barrel cover B. The barrel mouth section area below the barrel mouth convex ring A1 is a barrel neck A2, and there is an arc-shaped cone wall transition section between the barrel neck A2 and the straight barrel wall of the barrel body, and the junction of the arc-shaped cone wall transition section and the straight barrel wall constitutes a barrel shoulder A3.

[0016] See also Figures 2 to 8 The transfer device shown,

[0017] The movable seat 21 and the movable platform 10 that move in a horizontal plane along the horizontally arranged guide rail 20 form a vertical relative displacement cooperation. The lower part of the movable platform 10 is connected to a clamping mechanism, which includes a support 30. The upper plate edges of the guide plates 50 arranged in an eight-shaped shape are fixed on the support 30. The horizontal distance between the plate surfaces on the opposite sides of the two guide plates 50 gradually increases from top to bottom. The upper end of the swing arm 60 is hinged on the support 30. The swing surfaces of the two swing arms 60 share a vertical plane. The two guide plates 50 are symmetrically distributed on the swing arm 60. 0, the vertical plane of the mirror symmetry plane of the guide plate 50 is arranged orthogonally to the swing surface of the swing arm 60 as a whole, and the lower end of the swing arm 60 is connected with an arc-shaped clamp 61, and the curvature range of the arc-shaped clamp 61 is smaller than a semicircle. When the swing arm 60 swings to the point where the arc-shaped clamp 61 approaches the barrel neck A2, the clamping openings of the two arc-shaped clamps 61 are clamped relative to each other at the barrel neck A2 at the lower edge of the barrel mouth convex ring A1. When the swing arm 60 swings to the point where the arc-shaped clamp 61 is away from the barrel neck A2, the opening between the clamping openings of the two arc-shaped clamps 61 is larger than the diameter of the barrel mouth convex ring A1.

[0018] In the above scheme, the movable seat 21 moves horizontally along the guide rail 20, driving the movable platform 10 to move horizontally together, and the movable platform 10 can produce vertical displacement along the track on the movable seat 21, so that the barrel A clamped under the movable platform 10 is transferred to the box body of the packaging box; the conveying unit conveys the barrel A to Figure 1 In the waiting position shown, the movable platform 10 is lifted to an appropriate height and moved above the barrel A to ensure that the clamping mechanism is above the barrel A in a substantially co-ordinated manner.

[0019] The movable platform 10 moves downward, so that the two guide plates 50 of the clamping mechanism approach the barrel body A. When there is a position error between the constraint area provided by the two arc-shaped clamps 61 and the barrel neck A2, as the two guide plates 50 approach the barrel body A, one guide plate 50 will first contact the barrel shoulder A3 on one side of the barrel body A, and push the barrel body A toward the direction close to the other guide plate 50, so that the two guide plates 50 contact the barrel shoulder A3 respectively. At this time, the barrel body A is at the symmetrical center plane position of the two guide plates 50. At this time, the two swing arms 60 swing toward the barrel cover B at the same time. When the swing arm 60 swings to the arc When the arc-shaped clips 61 are close to the barrel neck A2, the clip mouths of the two arc-shaped clips 61 are clamped relative to each other at the barrel neck A2 at the lower edge of the barrel mouth convex ring A1, and then the movable platform 10 rises and horizontally translates to above the placement position of the packaging box, and then the barrel body A falls into the packaging box through the descending action of the movable platform 10, and finally the two arc-shaped clips 61 swing away from each other to release the barrel body A. It should be noted that when the two arc-shaped clips 61 swing towards each other, the constraints they provide drive the barrel body A to move toward the symmetrical center position of the two arc-shaped clips 61, thereby achieving the two arc-shaped clips 61 can be reliably and accurately clamped at the barrel neck A2.

[0020] like Figure 3 , 5 As shown, the guide plate 50 is formed by connecting a straight plate 51 and an arc plate 52, the upper plate edge of the straight plate 51 is fixedly connected to the bottom of the support 30, and the upper plate edge of the arc plate 52 is connected to the bottom of the straight plate 51; the arc plate 52 is curved from top to bottom, and its specific curvature should ensure that the arc plate 52 can abut against the barrel shoulder A3 during the descent process, and ensure that the barrel body A can be displaced to the symmetrical center plane of the two arc plates 52, and prevent the barrel body A from tipping over when the arc plate 52 pushes the barrel body A; therefore, the curvature of the arc plate 52 needs to be set according to the arc cone wall transition section on the corresponding barrel body A.

[0021] like Figure 6 , 7 As shown, when the guide plate 50 is pressed against the barrel body A on the opposite side of the barrel body A at the same time, the guide plate 50 is close to the barrel shoulder A3 and the part of the barrel body A below the barrel shoulder A3; the curved section of the guide plate 50 is arranged in this way to ensure that when the barrel body A is pushed by one guide plate 50, it can move toward the side close to the other guide plate 50, that is, stably displace toward the symmetrical center plane of the two guide plates 50.

[0022] The arc-shaped clamp 61 includes an upper table 611 that supports the lower end surface of the barrel mouth convex ring A1, and the lower part of the upper table 611 is a chamfered inclined surface 612, the upper side of the chamfered inclined surface 612 is close to the arc edge of the arc-shaped clamp 61, and the lower side of the chamfered inclined surface 612 is far away from the arc edge of the arc-shaped clamp 61; when the two arc-shaped clamps 61 are clamped at the barrel neck A2, the lower end surface of the barrel mouth convex ring A1 is placed on the top of the upper table 611, and when the barrel body A is lifted, the cooperation between the arc-shaped clamp 61 and the barrel mouth convex ring A1 ensures that the barrel body A can be lifted up reliably; the chamfered inclined surface 612 has two main functions. On the one hand, when the two swing arms 60 swing downward and the arc-shaped clamps 61 approach each other, the chamfered inclined surface 612 approaches the displacement from the barrel shoulder A3 along the arc-shaped cone wall transition section, thereby correcting the barrel core of the barrel body A. There is no misalignment between the position and the symmetrical center plane of the arc-shaped card 61, and when the barrel core position of the barrel body A basically coincides with the symmetrical center plane of the arc-shaped card 61, the chamfered inclined surface 612 and the arc-shaped cone wall transition section on the barrel body A are separated and matched in a gap-type manner, so as to avoid the chamfered inclined surface 612 from squeezing the arc-shaped cone wall transition section on the barrel body A; on the other hand, the distance between the lower end surface of the barrel mouth convex ring A1 and the top of the arc-shaped cone wall transition section is very small, that is, the height of the barrel neck A2 is very small, and the arc-shaped card mouth part of the arc-shaped card 61 formed by the upper table 611 and the chamfered inclined surface 612 is wedge-shaped in the cross section in the plumb direction, thereby ensuring that the arc-shaped card 61 can smoothly reach the bottom of the barrel mouth convex ring A1 when it swings and ensure that it can be supported on the lower end surface of the barrel mouth convex ring A1.

[0023] There are arc blocks 62 on the two swing arms 60 above the arc-shaped clamp 61. When the swing arm 60 swings to the adjacent position, the arc-shaped notch on the arc block 62 forms an enclosure area for constraining the circumference of the barrel cover B. The two arc blocks 62 clamp the barrel cover B. When the barrel body A is lifted, the barrel body A is not easy to shake, and the rotation of the barrel body A during transportation is avoided. Because the barrel body A is square in shape, it is necessary to ensure that the corresponding side walls of the barrel body A are coplanar during packing. A soft pad 621 is arranged on the wall surface of the arc-shaped notch on the arc block 62. The setting of the soft pad 621 not only does not cause damage to the bottle cap B, but also can limit the rotation of the barrel body A during transportation.
