For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0027] At present, the outgoing flow of stem tags is mainly monitored manually to determine whether the amount of stem tags removed is qualified. This monitoring method is difficult to detect abnormalities in the amount of stem tag removal in a timely manner, consumes manpower and has low efficiency.

[0028] In order to solve the above technical problems, the utility model provides a monitoring device, which can automatically monitor the amount of stem sticks rejected, which not only improves the efficiency but also saves manpower.

[0029] In order to make the technical solution and advantages of the present invention more clear, the implementation methods of the present invention are described in further detail below.

[0030] refer to Figure 1 and Figure 2 The embodiment of the utility model provides a monitoring device, including a wire receiving plate 1, a weight sensor 2 and an alarm (not shown in the figure). The rejected stems are discharged outward from the discharge hopper 3, and the discharge hopper 3 is arranged in a vertical direction (such as Figure 1 The discharge hopper 3 is provided with a feed inlet at the top and a discharge outlet at the bottom. The wire receiving plate 1 is provided in the discharge hopper 3. The wire receiving plate 1 can rotate between a first position and a second position relative to the discharge hopper 3. When the wire receiving plate 1 is in the first position, the upper surface of the wire receiving plate 1 is aligned with the horizontal direction (as shown in the Y direction in FIG. 1 ). Figure 1 The X direction in the figure is parallel to each other. Figure 1 As shown, at this time, the stems input from the feed port into the discharge hopper 3 can fall onto the upper surface of the wire receiving plate 1. When the wire receiving plate 1 is in the second position, the upper surface of the wire receiving plate 1 is parallel to the vertical direction, as shown in FIG. Figure 2 As shown, at this time, the stems input into the discharge hopper 3 can be discharged from the discharge port at the bottom of the discharge hopper 3. The weight sensor 2 is connected to the wire connecting plate 1, and the weight sensor 2 is located at the bottom of the wire connecting plate 1. The weight sensor 2 is used to detect the total weight of the wire connecting plate 1 and the stems located on the wire connecting plate 1 when the wire connecting plate 1 is located at the first position. The alarm is electrically connected to the weight sensor 2, and when the total weight is greater than or equal to the preset upper limit value or less than or equal to the preset lower limit value, the alarm can sound an alarm. Among them, the preset upper limit value is the upper limit value in the standard range of the stem rejection amount per unit time, and the preset lower limit value is the lower limit value in the standard range of the stem rejection amount per unit time.

[0031] When the stem sticks are normally output, the wire connecting plate 1 is rotated to the second position, so that the stem sticks input into the discharge hopper 3 are normally discharged. When it is necessary to detect whether the stem stick rejection amount is qualified, the wire connecting plate 1 is rotated to the first position, so that the stem sticks input into the discharge hopper 3 fall into the groove formed on the upper surface of the wire connecting plate 1. Within a unit time, if the weight sensor 2 detects that the total weight of the wire connecting plate 1 and the stem sticks falling on the wire connecting plate 1 is greater than or equal to the preset upper limit value or less than or equal to the preset lower limit value, it means that the output flow of the stem sticks is too large or too small at this time, and the alarm immediately sounds an alarm to remind the operator that the stem stick rejection amount is abnormal. This method of monitoring the stem stick rejection amount is not only efficient, but also saves manpower.

[0032] Optionally, a driving mechanism is further included, connected to the wire connecting plate 1, and the driving mechanism is used to drive the wire connecting plate 1 to rotate between the first position and the second position. Figure 1 and Figure 2 The driving mechanism includes a transmission shaft 4 and a rotating cylinder 5. The transmission shaft 4 is connected to the wire connecting plate 1. The transmission shaft 4 passes through the side wall of the discharge hopper 3. The transmission shaft 4 can drive the wire connecting plate 1 to rotate around the axis of the transmission shaft 4 between the first position and the second position. The rotating cylinder 5 is arranged outside the discharge hopper 3. The rotating cylinder 5 is connected to the transmission shaft 4. The rotating cylinder 5 is used to drive the transmission shaft 4 to rotate around its own axis, thereby driving the wire connecting plate 1 to rotate between the first position and the second position. The utility model can drive the wire connecting plate 1 to rotate between the first position and the second position by setting a driving mechanism to realize automatic control.

[0033] Optionally, a timer 6 and a control system (not shown in the figure) are further included. The control system is electrically connected to the timer 6 and the rotary cylinder 5, respectively. The timer is used to count the time that the wire connecting plate 1 stays at the first position and the second position. The control system is used to control the rotary cylinder 5 to drive the wire connecting plate 1 to rotate to the second position when the time that the wire connecting plate 1 stays at the first position reaches a first preset time, and to control the rotary cylinder 5 to drive the wire connecting plate 1 to rotate to the first position when the time that the wire connecting plate 1 stays at the second position reaches a second preset time.

[0034] When the stems begin to be discharged outward through the discharge hopper 3, the wire plate 1 is located at the second position, and the timer 6 starts timing. When the time when the wire plate 1 is located at the second position reaches the second preset time, the control system controls the wire plate 1 to rotate to the first position, so that the stems fall to the upper surface of the wire plate 1, thereby starting to monitor the amount of stems removed. When the time when the wire plate 1 is located at the first position reaches the first preset time (i.e., unit time), if the weight sensor 2 does not detect that the weight of the wire plate 1 and the stems is greater than or equal to the preset upper limit value or less than or equal to the preset lower limit value within the unit time, it means that the amount of stems removed is normal at this time, and the control system controls the wire plate 1 to return to the second position. When the time when the wire plate 1 is located at the second position reaches the second preset time again, the above process is repeated to realize automatic timed monitoring of the amount of stems removed. Once an abnormality in the amount of stems removed is detected, the alarm immediately sounds an alarm to remind the operator.

[0035] Optionally, the alarm is an audible and visual alarm, which can emit a loud sound and obvious light to enable an operator to more easily discover the alarm.

[0036] Optionally, a display (not shown in the figure) is further included, which is arranged outside the discharge hopper 3. The display is electrically connected to the weight sensor 2, and the display is used to display the value of the total weight of the wire connecting plate 1 and the stems on the wire connecting plate 1. The utility model is convenient for the operator to intuitively monitor the wire connecting plate 1 and the total amount of stems rejected per unit time by designing the display. In actual production, the weight of the wire connecting plate 1 can be subtracted from the total weight displayed on the display by manual or electronic equipment to obtain the amount of stems rejected per unit time.

[0037] Optionally, the wire connecting plate 1 is made of stainless steel, which has good corrosion resistance and can increase the service life of the wire connecting plate 1.

[0038] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above contents are further detailed descriptions of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art may make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
