Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The label rejecting assembly of the invention comprises: the rotary adsorption drum is provided with a plurality of adsorption parts for adsorbing labels along the circumferential direction on the surface; a gap for the label to pass through is arranged between the shunting unit and the adsorption roller; a label removing unit disposed beside a circumference of the adsorption drum; when the shunting unit is not triggered by the controller, the label passes through the gap; when the shunting unit is triggered by the controller, the shunting unit pushes the labels passing through the gap to the adsorption roller, and the labels are adsorbed and removed by the adsorption roller. The embodiment of the invention pushes unqualified or qualified labels passing through the gap between the shunting unit and the adsorption roller to the adsorption roller through the shunting unit, and a plurality of adsorption parts for adsorbing the labels are distributed on the surface of the adsorption roller along the circumferential direction, so that the labels pushed to the adsorption roller by the shunting unit can be adsorbed by one adsorption part on the circumferential surface when the adsorption roller rotates to any position, and then the labels adsorbed on the surface of the adsorption roller are removed from the surface of the adsorption roller by the label removing unit when the adsorption roller rotates to the label removing unit arranged beside the circumference of the adsorption roller, thereby realizing the separation of the unqualified labels and the qualified labels and further realizing the elimination of the unqualified labels. The adsorption drum can arrange the adsorption parts densely on the surface in the circumferential direction of the adsorption drum for adsorbing the labels, has a large application range, is suitable for labels with any length, is not limited by the length of the labels, does not need to position the adsorption parts, and has simple structure and low cost.
Example one
As shown in fig. 1, an embodiment of the invention provides a label rejecting assembly 10, including:
a plurality of adsorption parts 111 for adsorbing the labels 20 are distributed on the surface of the rotary adsorption roller 11 along the circumferential direction;
a gap for passing the label 20 is arranged between the shunting unit 12 and the adsorption roller 11;
a label removing unit 13 disposed beside the circumference of the adsorption drum 11 for removing the labels 20 on the adsorption drum 11;
a controller (not shown in the figure) connected to the shunting unit 12 for triggering the shunting unit 12 to operate;
when the diversion unit 12 is not triggered by the controller, the label 20 passes through the gap;
when the diverting unit 12 is triggered by the controller, the diverting unit 12 pushes the label 20 passing through the gap toward the suction drum 11, and the label 20 is sucked and removed by the suction drum 11.
The suction unit 111 has a suction force and can suck the label 20 on the surface of the suction drum 11 or near the surface of the suction drum 11. The plurality of suction portions 111 are arranged in a circle along the circumference of the surface of the suction drum 11, and the smaller the distance between two adjacent suction portions 111 on the circumference of the surface of the suction drum 11, the smaller the length of the label 20 to be sucked may be, and thus, the denser the suction portions 111 are arranged along the circumference of the surface of the suction drum 11, the larger the adaptation range is. Of course, in order to accommodate simultaneous picking of a plurality of rows of labels 20, a plurality of suction cylinders 11 may be provided in the axial direction to form a suction net arranged in a horizontal and vertical net shape, and the number of suction portions 111 in each row in the axial direction of the suction cylinder 11 is greater than or equal to the number of labels 20 in each row.
The distance between the adsorption roller 11 and the label 20 can be determined according to the suction force of the adsorption part 111, the distance between the adsorption roller 11 and the label 20 satisfies that in the normal transmission process of the label 20, the label 20 cannot be sucked by the suction force of the adsorption part 111, and the adjustment of the distance between the adsorption roller 11 and the label 20 can be realized through limited experiments. Of course, after the distance between the suction drum 11 and the label 20 is determined, the suction force of the suction unit 111 may be adjusted so that the label 20 cannot be sucked by the suction force of the suction unit 111.
The diverting unit 12 is used to push the label 20 toward the suction drum 11.
The label removing unit 13 may be constituted by a side edge of the label recovery box 14 disposed beside the circumference of the adsorption drum 11, a distance between the side edge and the outer circumference of the adsorption drum 11 is smaller than a thickness of the label 20, and when the label 20 adsorbed by the adsorption portion 111 of the adsorption drum 11 rotates to the side edge of the label recovery box 14, the label 20 on the circumference of the adsorption drum 11 is scraped by a blocking action of the side edge of the label recovery box 14, and the scraped label 20 falls into the label recovery box 14.
The label removing unit 13 may also scoop the labels 20 on the circumference of the adsorption drum 11 by negative pressure suction or blower blowing, which requires a force greater than the suction force of the adsorption part 111. The suction nozzle or the blowing nozzle of the label removing unit 13 faces the circumference of the adsorption drum 11, and the suction by negative pressure or the blowing by the blower may not contact the label 20 adsorbed on the circumference of the adsorption drum 11.
The label removing unit 13 may also separate the label 20 adsorbed on the circumference of the adsorption drum 11 from the adsorption drum 11 by means of gluing.
The controller is used for controlling the on-off of the switch of the shunt unit 12 and triggering the shunt unit 12 to start working or stop working. After receiving the signal, the controller triggers the diverting unit 12 to operate, so as to push the label 20 passing through the gap toward the adsorption roller 11, and make the adsorption part 111 of the adsorption roller 11 adsorb the label 20.
The label reject assembly 10 of the present invention can select either a good label 20 or a bad label 20. The signal received by the controller, the detection of the tag 20 can be realized by a computer and a camera, the camera shoots the picture of the tag 20 and transmits the picture to the computer, the computer compares whether the picture shot by the camera is different from the picture of the standard tag 20 stored in the computer, if so, the tag 20 which needs to be selected is determined, the tag 20 can be a qualified tag 20 or an unqualified tag 20, and the detection of the tag 20 is a mature technology and is not a protection point of the invention, which is not described herein again. When the computer detects the different labels 20, a signal is sent to the controller, and the controller delays a preset time after receiving the signal to trigger the shunting unit 12 to work, so that the labels 20 passing through the gap are pushed to the adsorption roller 11, and the adsorption part 111 of the adsorption roller 11 adsorbs the labels 20. Since the distance between the tag 20 photographed by the camera and the tag 20 passing through the gap can be determined, and the moving speed of the tag 20 can be determined, a preset time required to be delayed after the controller receives the signal can be calculated.
The working process of the invention is as follows: when the label separating device works, the adsorption roller 11 continuously rotates, and the separating unit 12 is not triggered, the separation device keeps a silent state and does not work, when the computer detects the different labels 20, a signal is sent to the controller, the controller delays the preset time after receiving the signal to trigger the separating unit 12 to work, and the labels 20 passing through the gap are pushed to the adsorption roller 11, so that the adsorption part 111 of the adsorption roller 11 adsorbs the labels 20.
In the embodiment of the invention, the unqualified or qualified labels 20 passing through the gap between the flow dividing unit 12 and the adsorption roller 11 are pushed to the adsorption roller 11 by the flow dividing unit 12, the adsorption parts 111 for adsorbing the labels 20 are distributed on the surface of the adsorption roller 11 along the circumferential direction, one adsorption part 111 faces the labels 20 when the adsorption roller 11 rotates to any position, the labels 20 pushed to the adsorption roller 11 by the flow dividing unit 12 can be adsorbed by the adsorption part 111 facing the labels 20 on the circumferential surface, and the labels 20 adsorbed on the surface of the adsorption roller 11 are removed from the surface of the adsorption roller 11 by the label removing unit 13 when the adsorption roller rotates to the label removing unit 13 arranged beside the circumference of the adsorption roller 11, so that the unqualified labels 20 and the qualified labels 20 are separated, and the unqualified labels 20 are removed. The adsorption part 111 can be densely distributed on the surface of the adsorption roller 11 in the circumferential direction for adsorbing the labels 20, so that the adsorption roller has a wide application range, is suitable for labels 20 with any length, is not limited by the length of the labels 20, does not need to position the adsorption part 111, and has a simple structure and low cost.
Example two
In an alternative embodiment of the present invention, as shown in fig. 1, the suction portion 111 is a suction hole, and the suction drum 11 is provided with a negative pressure chamber 112 communicating with the suction portion 111, and a negative pressure source 15 communicating with the negative pressure chamber 112.
The negative pressure source 15 is an exhaust fan or a vacuum pump, etc. for providing negative pressure to the negative pressure cavity 112. In the present invention, all the suction holes are communicated with the negative pressure chamber 112, so that each suction hole has a suction force for sucking the label 20 on the circumference of the suction drum 11.
In the present invention, the plurality of suction portions 111 share one negative pressure chamber 112 and one negative pressure source 15, so that the suction force of each suction portion 111 can be kept consistent, and the occurrence of a phenomenon that the label 20 drops halfway due to insufficient suction force or a phenomenon that the label 20 which is normally transported on the transport belt is sucked to cause a phenomenon of erroneous suction can be prevented. And because the suction force of each adsorption part 111 is the same, when the distance between the adsorption roller 11 and the label 20 is adjusted, only the suction force of one adsorption part 111 needs to be adjusted, and the adjustment is convenient. Of course, in order to increase the negative pressure of the negative pressure chamber 112, a plurality of negative pressure sources 15 may be used to collectively supply the negative pressure to one negative pressure chamber 112.
EXAMPLE III
In an alternative embodiment of the present invention, as shown in fig. 1, the shunting unit 12 includes:
an air blow gun;
a gas source (not shown) in communication with the gas blow gun;
and the electromagnetic valve (not shown in the figure) is arranged between the air blow gun and the air source and is used for controlling the air blow gun to work.
In the embodiment of the invention, the air outlet of the air blowing gun faces the label 20 passing through the gap, a gap is reserved between the air blowing gun and the label 20, the air blowing gun does not move and does not contact with the label 20 when in work, air flow is blown out from the air outlet of the air blowing gun, and the label 20 is blown to the adsorption roller 11 by the air flow from the air outlet of the air blowing gun.
The air source is a compressed air source and is used for providing high-pressure air flow for the air blowing gun.
The electromagnetic valve is controlled by the controller and is used for controlling the on-off of an air source of the air blowing gun, when the electromagnetic valve is opened, the air source provides high-pressure air flow for the air blowing gun, and when the electromagnetic valve is closed, no air flow exists in the air blowing gun. After the controller receives a signal that the labels 20 are required to be shunted (including the labels 20 which are qualified or the labels 20 which are unqualified), the shunting unit 12 is triggered, the controller opens the electromagnetic valve, the shunting unit 12 blows the labels 20 passing through the gap to the adsorption roller 11 through the air blowing gun, and then the labels 20 are adsorbed and removed by the adsorption roller 11. When the controller does not receive the signal of needing to shunt the labels 20, the shunting unit 12 is not triggered, the electromagnetic valve of the shunting unit 12 is closed, and the labels 20 normally pass through the gap.
The embodiment of the present invention uses the air blow gun without touching the label 20, and therefore, the embodiment of the present invention is applicable to both the label 20 with glue and the label 20 without glue.
Example four
As shown in fig. 1, in an alternative embodiment of the present invention, the flow dividing unit 12 includes:
a movable ejector rod;
a driving member (not shown) for driving the movable ram to move.
Under the driving of the driving member, the movable ejector pin can push the label 20 passing through the gap to the suction roller 11, and the label 20 is sucked and removed by the suction roller 11. The drive member may be a linear motor, cylinder, piston, or the like. The drive member is controlled by a controller. After the controller receives a signal that the labels 20 are required to be shunted (including the labels 20 which are qualified after being shunted or the labels 20 which are unqualified after being shunted), the shunting unit 12 is triggered, the controller controls the driving piece to work, the shunting unit 12 pushes the labels 20 passing through the gap to the adsorption roller 11 through the movable ejector rod, and then the labels 20 are adsorbed and removed by the adsorption roller 11. When the controller does not receive the signal that the label 20 needs to be shunted, the shunting unit 12 is not triggered, the driving member does not work, and the label 20 normally passes through the gap.
