The plate passes through the space between the light-emitting source and the receiver in the detection device, the light-emitting source emits light on the surface of the plate, and if the surface of the plate has no hole defect, the plate is directly conveyed to the stacking device for stacking and packaging through the conveying device. If holes exist on the surface of the plate, light emitted by the light-emitting source passes through the positions of the holes and is received by the receiver. And then the receiver controls the sorting device to work according to the transmission speed of the conveying device to the plates, and the sorting device directly pushes down the plates with holes from the conveying device, so that the conveying device only conveys the finished plates without holes to the stacking device for stacking. Above-mentioned simple structure, under detection device and sorting device's automatic cooperation, will exist the defective products panel letter sorting of hole fast and come out, need not artifical manual letter sorting, not only can guarantee the production quality of panel, moreover, effectively reduce artifical intensity of labour in the assurance panel machining efficiency.

Further, sorting device is including unloading cylinder and the waste material frame that is located conveyer both sides respectively, the one end that the unloading cylinder is close to the waste material frame is equipped with and is connected with the push pedal that is located the conveyor top and set up along panel direction of delivery, unloading cylinder and receiver communication connection.

Referring to fig. 1, in the present embodiment, the first discharging roller set 101 and the second discharging roller set 102 each include a discharging frame 11 and a plurality of discharging rollers 111 disposed in an array along a conveying direction of the sheet material and positioned rotatably mounted on the discharging frame 11, and the discharging rollers 111 are disposed horizontally along a conveying direction perpendicular to the sheet material. The discharging roller 111 on the first discharging roller set 101 is a driving roller, the discharging roller 111 on the second discharging roller set 102 is a driven roller, and the rotation of the driving roller is controlled by a motor, which is the same as that in the prior art, and is not described in detail and is not shown in the drawings.

Referring to fig. 1 and 4, a base plate is placed on the first discharging roller group 101, and then the sheet is dropped directly from the swing arm 82 and stacked on the base plate in sequence. When the plates are stacked to a certain height, the plurality of discharging rollers 111 in the first discharging roller set 101 are driven to rotate, the bottom plate and the stacked plates on the bottom plate are conveyed to the second discharging roller set 102, namely, the stacked plates are moved out from the lower part of the stacking frame 81, so that the stacked plates are conveniently packed and packaged, and the influence on the stacking device 8 to continue stacking operation can be avoided.

After the plate is packaged, a label is generally attached to mark the type of the plate, so that a customer can identify the use. However, during transportation or storage, the label is easy to fall off, and in order to facilitate the customer to identify the type of the board after the label is lost, referring to fig. 1, a marking device 3 is provided on a side of the feeding frame 21 near the unwinding device 1 away from the unwinding device 1. Referring to fig. 5, in the present embodiment, the marking device 3 includes a marking frame 31 parallel to the feeding frame 21, marking bars 32 horizontally arranged in a direction perpendicular to the sheet conveying direction are symmetrically provided on the marking frame 31, and two marking bars 32 are slidably mounted on the marking frame 31 in the sheet conveying direction. Referring to fig. 5, a plurality of corresponding half holes 321 are arranged on one side of the two marker strips 32, which are close to each other, along the length direction thereof, and the half holes 321 on the two marker strips 32 are vertically arranged in a one-to-one correspondence manner to form a placement hole 33 penetrating the marker strips 32, and a marker 34 is placed in the placement hole 33.

In order to adjust and fix the position of the marking strip 32 so that the placement holes 33 can place and fix the marking pens 34 of different thicknesses, referring to fig. 5, a guide groove 311 is provided on the marking frame 31, which is horizontally provided perpendicular to the marking strip 32, and both ends of the marking strip 32 are slidably installed in the guide groove 311, respectively. Referring to fig. 5, a screw rod 35 which is disposed along the length direction thereof and is in threaded connection with the marking strips 32 is rotatably installed in one of the guide grooves 311 in a positioning manner, the screw rod 35 is in opposite threaded connection with the two marking strips 32, and one end of the screw rod, which is far away from the unwinding device 1, extends out of the guide groove 311 and is connected with a hand wheel 351 which facilitates driving the rotation thereof.

Referring to fig. 5, a marker 34 with proper color and thickness is selected, a hand wheel 351 is rotated to drive a screw rod 35 to rotate, and under the threaded connection effect of the screw rod 35 and the marker strips 32, the two marker strips 32 can be driven to move towards or away from each other, so that the size of the placement hole 33 is adjusted to be matched with the marker 34. The marker 34 is inserted into the placement hole 33 at a corresponding position according to actual needs, so that when the feeding device 2 feeds the aluminum strip unreeled by the unreeling device 1, the marker 34 can leave a marker line drawn along the length direction of the aluminum strip on the surface of the aluminum strip. Therefore, when the packaged label is lost, the model of the plate can be conveniently identified, so that a customer can accurately use the plate.

The working principle and the using method of the invention are as follows:

whether the marking device 3 is used for marking is determined according to the actual needs of customers, if the marking device 3 is used, the marking pen 34 is installed according to the actual needs, and if the marking device is not used, the aluminum strip is directly unreeled by the unreeling device 1. The aluminum strip fed to the cutter device 4 by the feeding device 2 passes through the space between the upper cutter 42 and the lower cutter 43, and the cutter device 4 works to cut the aluminum strip into plates with required lengths. The sheet then passes between the two connection plates 52 onto the conveyor belt 62, and the light source 53 emits light to the surface of the sheet. If holes exist on the surface of the plate, light emitted by the light-emitting source 53 passes through the positions of the holes and is received by the receiver 54, and the receiver 54 controls the blanking cylinder 71 to work according to the conveying speed of the conveyor belt 62 to the plate. The blanking cylinder 71 drives the pushing plate 711 to push the waste plates with holes on the conveyor belt 62 to the waste frame 72. Under the action of the telescopic supporting rods 75 and the tension springs 751, each waste plate is added on the supporting plate 74, the supporting plate 74 drives the waste plates to move downwards for a certain distance, and the upper end face of the uppermost waste plate is always level with the upper end face of the conveying belt 62, so that the waste plates are orderly stacked.

If the surface of the plate has no hole defect, the plate moves directly from the conveyor belt 62 to the two swing arms 82 and is put on the rollers 83. After the inductor 91 senses that the end part of the plate sent out to the swing arm 82 by the conveyor belt 62 is abutted against the limiting block 9, the inductor 91 automatically controls the stacking cylinder 84 to work, the stacking cylinder 84 drives the two swing arms 82 to open in the mutually-away direction, and after the supporting effect of the roller 83 is lost, the plate directly falls onto the bottom plate on the first discharging roller set 101. With this reciprocation, when the sheet is stacked to a certain height, the plurality of discharging rollers 111 in the first discharging roller set 101 are driven to rotate, and the bottom plate and the stacked sheet on the bottom plate are transferred to the second discharging roller set 102, so as to pack the stacked sheet, and the stacking device 8 continues to perform stacking work.
