DETAILED DESCRIPTION

[0027] The specific embodiments of the present application will be further described below in conjunction with the embodiments. The following embodiments are only used to more clearly illustrate the technical scheme of the present application, and cannot be used to limit the protection scope of the present application.

[0028] In the description of the present application, it should be explained that, unless otherwise specified, the meaning of "a plurality of" is more than two; the orientation or position relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer" and the like is only for the convenience of describing the present application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0029] In the description of the present application, it should be explained that, unless otherwise specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected. For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0030] In the description of the present application, "first", "second" and the like are used to distinguish different objects, and are not used to describe a specific order or primary and secondary relationship.

[0031] The outer contour of the film-coated bale neck is cylindrical, including opposite first end face, second end face and circumferential side face, the first end face is used for connecting with the bale cover part, which is a rubber surface without film coating; the second end face and the side face are both polytetrafluoroethylene surface with film coating, and the friction coefficient of the rubber surface is greater than that of the polytetrafluoroethylene surface. EMBODIMENT

[0032] As Figures 1-3As shown, the visual inspection and feeding device for the neck of the coated plug in the embodiment includes a continuous conveying mechanism 1 and a plug sorting member 2; the continuous conveying mechanism 1 has a working surface 1a supported on the plug neck; the plug sorting member 2 is fixedly arranged above 1a, and the plug sorting member 2 has a lateral pushing surface 2a; the working surface 1a includes an upper plug area 101, a row of plug areas 102 and a plug-out area 103 protruding from the pushing surface 2a and arranged in sequence along the conveying direction; the working surface 1a has a first side edge 1b opposite to the pushing surface 2a, and the distance between the pushing surface 2a and the first side edge 1b gradually decreases from the upper plug area 101 to the plug-out area 103, and the pushing surface 2a is configured to push the plug neck of the plug-out area 103 away from the working surface 1a.

[0033] The continuous conveying mechanism 1 functions to provide a continuous working surface 1a. The continuous conveying mechanism 1 optionally includes a conveyor belt or a turntable. When the continuous conveying mechanism 1 is a conveyor belt, the upper blocking area 101, the blocking area 102, and the blocking area 103 are arranged in a straight line. When the continuous conveying mechanism 1 is a turntable, the upper blocking area 101, the blocking area 102, and the blocking area 103 are arranged in an arc shape. Optionally, the upper blocking area 101 and the blocking area 103 are arranged adjacent to each other or spaced apart.

[0034] When the plug necks fed into the upper plugging area 101 have a predetermined orientation, the plug necks discharged from the discharging area 103 also have a fixed orientation. When passing through the plug array area 102, the plug necks on the working surface 1a are sorted and arranged in a predetermined array width area. This array area is located at the first side 1b of the working surface 1a. Typically, this array width is the width of a single row.

[0035] When the continuous conveying mechanism 1 is a conveyor belt, the width of the conveyor belt is the first direction; when the continuous conveying mechanism 1 is a turntable, the radial direction of the turntable is the first direction. The distance between the push surface 2a and the first side edge 1b is also the distance along the first direction. Optionally, the minimum distance between the plug exit area 103 and the first side edge 1b is 0, so that the plug neck is completely pushed away from the working surface 1a by the push surface 2a.

[0036] like Figure 2 As shown, in some preferred embodiments, the push surface 2a smoothly transitions from the upper plug area 101 to the plug exit area 103. When the upper plug area 101 to the plug exit area 103 form a stepped transition, plug necks are prone to lingering at the stepped corners where the upper plug area 101 approaches the array of plug areas 102, and at the stepped corners where the array of plug areas 102 approaches the plug exit area 103. The smoothly transitioned push surface 2a pushes plug necks near the push surface 2a toward the first side edge 1b, ultimately arranging them into a single row of plug necks in the plug exit area 103, with no plug necks remaining.

[0037] like Figure 1As shown, in some preferred embodiments, the visual inspection feeding device further includes a plugging mechanism 3, which is configured to feed plugs to the upper plugging area 101. Optionally, the plugging mechanism 3 provides the upper plugging area 101 with a plug that meets the plug-out orientation.

[0038] like Figures 1-3 As shown, in some preferred embodiments, the continuous conveying mechanism 1 is a turntable. Compared with a conveyor belt, a turntable occupies less space and has a compact feeding device structure. The turntable is made of rigid material, which is less likely to introduce impurities into the stopper neck than the flexible material of a conveyor belt.

[0039] like Figures 2-3 As shown, in some preferred embodiments, a vibration guide groove 4 is provided on the side of the plug-out region 103 facing away from the push surface 2a. The groove surface of the vibration guide groove 4 is lower than the plug-out region 103. The push surface 2a is at least partially flush with the first side 1b of the plug-out region 103. In this embodiment, the distance between the push surface 2a and the first side 1b of the plug-out region 103 is reduced to zero by the width of the single-row plug neck.

[0040] When the plug-loading mechanism 3 provides plug necks in any orientation for the upper plug area 101, a rejection mechanism is required to remove plug necks that do not meet the plug-out orientation from the working surface 1a. Optionally, the plug-loading mechanism 3 that provides plug necks in any orientation can be a vacuum loader that simultaneously loads multiple plug necks into the upper plug area 101 and, after rejection, leaves plug necks that meet the plug-out orientation on the working surface 1a.

[0041] like Figures 1-4 As shown, in some preferred embodiments, a plugging brush roller 5 is rotatably mounted on the discharge side of the plugging mechanism 3; the distance between the plugging brush roller 5 and the working surface 1a is less than the height of a single rubber plug; the direction from the push surface 2a to the first side edge 1b is a first direction, which is consistent with the rotational tangent direction of the plugging brush roller 5. The first direction is also the radial direction of the rotating disk working surface.

[0042] The plug neck portion where the rubber surface contacts the working surface 1a is the first plug neck portion, and the plug neck portion where the polytetrafluoroethylene surface contacts the working surface 1a is the second plug neck portion. Under the influence of the force of the plug-picking brush roller 5, the first plug neck portion is mostly retained on the working surface 1a, while the second plug neck portion is brushed off the working surface 1a. The rotation speed of the plug-picking brush roller 5 is adjusted according to the number of upper plugs and the conveying speed of the working surface 1a of the continuous conveying mechanism 1. Based on the predetermined distance between the upper plug push surface 2a and the first side edge 1b, the more upper plugs there are, the more layers of rubber plugs are accumulated, the longer it takes to remove the upper plug neck portion and the second plug neck portion using the plug-picking brush roller 5, and the slower the conveying speed of the working surface 1a of the continuous conveying mechanism 1.

[0043] The process of removing the upper stopper neck and the second stopper neck is roughly divided into two steps:

[0044] Firstly, the first step is to remove the upper rubber plug by the removing brush roller 5, and leave a single layer of plug neck on the working surface 1a;

[0045] Secondly, the second plug neck in the single layer of plug neck is removed. It can be understood that when the second plug neck is removed, part of the first plug neck is inevitably removed, which affects the feeding speed. The feeding speed is improved by appropriately increasing the conveying speed of the working surface 1a of the continuous conveying mechanism 1 and the rotating speed of the removing brush roller 5.

[0046] As shown in Figure 4 In some preferred embodiments, the plug arranging member 2 is provided with a recess 201 for accommodating the removing brush roller 5. The recess 201 can be a local recess on the pushing surface 2a, or a whole recess penetrating the plug arranging member 2 in the vertical direction.

[0047] In some preferred embodiments, the working surface 1a is a smooth surface, such as a smooth polymer material surface or a glass surface. The smooth surface and the rubber surface of the plug neck adhere to each other, which is beneficial to reduce the probability that the first rubber plug is brushed off the working surface 1a by the removing brush roller 5.

[0048] As shown in Figure 1 In some preferred embodiments, the visual detection feeding device further comprises a box 6, the continuous conveying mechanism 1 and the plug arranging member 2 are arranged in the box 6, and the box 6 is provided with a plug outlet at the bottom, which is communicated with the plug feeding mechanism 3. The plug neck kicked off the working surface 1a is fed back to the plug feeding area 101 through the plug feeding mechanism 3, and the cycle operation is realized. Further, the box 6 is provided with a feeding port, so that the rubber plug can be supplemented into the box 6 in time, and the supplement operation does not affect the normal plug arrangement.

[0049] In the embodiment detection device, the visual detection feeding device for the film-coated plug neck is included.

[0050] The above description is only the preferred embodiments of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should be considered as the protection scope of the present application.
