The invention is further described below with reference to the figures and the specific embodiments of the description.
As shown in fig. 1, in the blanking detection method for the blister machine of the present embodiment, after a single blanking operation is completed, a blanking device 1 of the blister machine transfers a blanked blister 4 to a conveying channel 3 in a region below the blanking device 1, and the conveying channel 3 of the blister machine starts to convey the blister 4 to a next station; when the conveying channel 3 runs for a fixed length distance L1, detecting whether a bubble cap 4 exists on the conveying channel 3 in the area below the blanking device 1, and when the bubble cap 4 is detected, judging that the conveying channel 3 is blocked; wherein the fixed-length distance L1 is not less than the distance travelled by the transfer channel 3 from the start to the moment when the blister 4 has just left the area below the blanking device 1. According to the blanking detection method for the bubble cap machine, after the conveying channel 3 runs for a fixed length distance in a single running process, whether bubble caps 4 exist on the conveying channel 3 in the area below the blanking device 1 or not is detected, and when the bubble caps 4 exist, blocking is prompted, so that the phenomenon that the bubble caps 4 left on the conveying channel 3 are damaged by the next blanking of the bubble caps 4 can be avoided, and smooth production is guaranteed.
It will be appreciated that the presence of blisters 4 on the conveyor path 3 in the area below the blanking device 1 can be checked continuously or intermittently (only once or several times periodically) before the conveyor path 3 travels the fixed length distance L1 until the start of the next blanking operation.
In the present embodiment, the conveyance path 3 is operated intermittently, that is, conveyance is started after receiving the punched blister 4, and conveyance is stopped after completion of conveyance, that is, the conveyance path 3 is stopped at the time of the next punching operation, and therefore, when the next punching operation is triggered, it is detected whether or not there is a blister 4 on the conveyance path 3 in the area below the punching device 1, and the reliability of detection can be ensured. In addition, the upper limit of the fixed-length distance L1 of the conveyance path 3 is the longest distance that the conveyance path 3 travels in a single run, i.e., the distance traveled from the start of the transfer to the stop.
In the embodiment, the lower area of the blanking device 1 is a forward projection area of a female die 15 of the blanking device 1 on the conveying channel 3; wherein the blister 4 is detected by the detection unit 2, the detection signal emitting end of the detection unit 2 is at the upstream position of the conveying channel 3, and the detection area is the area S between the upstream position of the conveying channel 3 and the forward projection position of the blister machine punching device 1 on the conveying channel 3, as shown in fig. 4. The projection position is a forward projection position of one end of the female die 15 of the blanking device 1 close to the downstream of the conveying channel 3 on the conveying channel 3.
In this embodiment, when the blister machine is started to perform the first blanking operation, whether the blister 4 is on the conveying passage 3 in the area below the blanking device 1 is detected, so that smooth production during starting is ensured.
In this embodiment, when a blister 4 is detected in the feed path 3, an alarm is given and/or the blanking operation is stopped.
As shown in fig. 2 to 4, the invention also discloses a blanking detection device for a bubble cap machine, which comprises a control unit and a detection unit 2, wherein the detection unit 2 is connected with the control unit, when the conveying channel 3 runs for a fixed length distance L1 after being started each time, the detection unit 2 detects whether a bubble cap 4 is on the conveying channel 3 in the area below the blanking device 1 and sends a detection signal to the control unit, and the control unit judges whether the conveying channel 3 is blocked according to the detection signal; wherein the fixed-length distance L1 is not less than the distance traveled by the transfer channel 3 from the normal start to the moment when the blister 4 has just left the area below the blanking device 1. The blanking detection device for the bubble cap machine is simple in structure, simple and convenient to operate and easy to realize.
In this embodiment, the detecting unit 2 includes a plurality of photoelectric detecting elements, which correspond to the respective conveying paths 3. Each photoelectric detection member is mounted at an upstream position of the corresponding conveying channel 3, the detection direction is the conveying direction of the conveying channel 3, and the detection area is slightly larger than the area between the upstream position of the conveying channel 3 and the forward projection position of the blister machine punching device 1 on the conveying channel 3, as shown in fig. 2. As shown in fig. 4, specifically, the photodetecting member is mounted on a mounting rod 21, and both ends of the mounting rod 21 are fixed on mounting plates 22 for mounting the driving roller of the conveying path 3.
When the whole machine is started to start production, the formed blister strip runs to a blanking station, and the blister 4 does not exist in the conveying channel 3 due to the fact that production is just started, the photoelectric detection piece cannot detect the blister 4, and the conveying channel 3 (discharging conveying belt) is also in a stop state all the time. Then, the main machine encoder detects that the motor runs to a position of a first preset value, which indicates that the first blanking action is finished, the discharge conveying belt is controlled to be started, the blanked bubble caps 4 are conveyed to the next station, when the belt runs for a distance L1, at the moment, the main machine encoder detects that the motor runs to a position of a second preset value, the photoelectric detection assembly detects the bubble caps 4 in the conveying channel 3, if yes, the controller sends out an alarm signal and stops the machine, otherwise, the production is continued, when the encoder monitors that the motor moves to a third preset value, which indicates that the second blanking operation is carried out, the photoelectric detection assembly detects the bubble caps 4 in the conveying channel 3 again, and if yes, the controller sends out an alarm and stops the machine; otherwise, the discharging conveying belt is controlled to stop, and simultaneously, the second blanking is started, and the actions are repeated.
