Description

  The present invention relates to a shredder chip detecting device capable of accurately detecting a chip height in a chip basket.

  As the level of knowledge rises, societies increasingly respect privacy, and shredders are an indispensable machine for households and businesses. A conventional shredder uses a sensing device such as a sensing rod or an elastic sheet to detect chips accumulated in the chip basket. When the shredder chip basket is full, paper will not enter from the upper insertion slot, so the user knows for the first time that the chip basket is full of chips.

  In the conventional sensing device, since the value of the sensing error is too large, it is not possible to sense the chip accumulation effectively, and even if the chip basket is full of chips, it does not sense, and the cutter flows backward. Entering into the cutter tends to cause a paper jam in the cutter or damage to the motor. Furthermore, there is a risk that the user may injure his / her finger by cleaning the chip-shaped chips from the cutter. In order to prevent this from happening, it is important to make a device that reliably detects the volume of chips accumulated inside the chip basket, and it is necessary to improve the prior art.

  The first object of the present invention is that an infrared receiver receives an infrared ray transmitted from a transmitter and reflected back to convert it into an electrical signal. Together with the voltage signal generated by the standard voltage signal generator of the other, it enters into a set of phase comparators, and another set of pulse wave or voltage generated after comparing the voltage and phase difference is used as the signal output data, and the pulse wave Another object of the present invention is to provide a shredder chip detecting device that can know the height of chips in a chip basket since the infrared reflection distance can be calculated or measured after the voltage is changed.

  The second object of the present invention is to install the inclined tank on the shredder case upper case bottom and higher than the cutter bottom, and install the infrared receiver / transmitter in the inclined tank. An object of the present invention is to provide a shredder chip detecting device for detecting the capacity of a chip basket below a case.

In order to solve the above problems, a shredder chip detection device of the present invention includes a shredder upper case, a chip basket, a circuit control panel body, an inclined tank, and a lamp,
Install an infrared receiver / transmitter in the circuit control panel body,
The shredder upper case is connected to the chip basket below, and an insertion port is installed above and a cutter is disposed below the insertion port,
The tilt tank is installed at the bottom of the upper case of the shredder and at a position higher than the bottom of the cutter, the circuit control panel body is disposed in the tilt tank, and the infrared receiver / transmitter transmits / receives infrared rays downward. And detecting the height of the chips accumulated in the tip basket,
The lamp measures and displays the remaining space in the chip basket through a pulse wave or voltage value generated by an interval time of infrared rays received and transmitted by the infrared receiver / transmitter.

  The present invention dynamically detects the height of chips stored in the chip basket by installing an infrared receiver / transmitter in the circuit control panel body, and also installs a lamp to receive / transmit infrared light. By measuring and displaying the remaining space in the tip basket dynamically through the pulse wave or voltage value generated by the interval time of the infrared rays received and transmitted by the device, the height of the chips in the tip basket can be safely and automatically It can be detected and displayed.

  In order to clearly show the structure of a shredder chip detecting device according to an embodiment of the present invention, a detailed description will be given with reference to the drawings.

  In the present embodiment, the output display lamp that represents the height of chips accumulated in the chip basket, that is, the remaining space of the chip basket, may be either an LED light emitting diode lamp or an LCD liquid crystal lamp. This output display lamp can effectively prevent the user's unauthorized operation, and the user can more accurately know whether the chip basket is full of chips.

  FIG. 1 is an explanatory diagram of a shredder chip detecting device according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of the upper shredder case of the present embodiment. FIG. 3 is a partially enlarged explanatory view of the infrared ray receiver / transmitter of the tilt tank and the circuit control panel body in the present embodiment. FIG. 4 is an enlarged explanatory view seen from another angle of the infrared receiver / transmitter in the inclined tank and the circuit control panel body in the present embodiment.

  As shown in the drawings, the shredder chip detecting device of the present embodiment includes a shredder upper case 14, a tip basket 16, an insertion slot 18, a cutter 20, a circuit control panel body 10, and an infrared receiver / transmitter 12. ing. The circuit control panel main body 10 is provided with an infrared receiver / transmitter 12. The infrared receiver / transmitter 12 includes a receiver 122 and a transmitter 121.

  The shredder upper case 14 is connected to a chip basket 16 positioned below, and receives and accumulates chips (paper waste) cut by a cutter 20 installed in the upper part of the shredder. An insertion port 18 is installed above the shredder upper case 14, and a cutter 20 is installed below the insertion port 18. An inclined tank 22 is installed at the bottom of the upper case 14, and the infrared signal receiving / transmitting is performed by installing the circuit control panel body 10 on the inclined tank 22 and at a position higher than the bottom of the cutter 20. The device 12 transmits / receives infrared rays downward, and dynamically detects the stored height of chips in the chip basket 16. The present embodiment further includes a transparent colored cover sheet 24 that covers the inclined tank 22.

  The lamp 26 detects and displays the capacity space in the chip basket 16 throughout the interval of receiving and transmitting infrared rays from the infrared receiver / transmitter 12. That is, the amount of chips stored in the chip basket 16 is detected using the infrared receiver / transmitter 12. The principle of this detection action is that after the infrared receiver 122 scans the intensity of the signal returned from the reflected infrared light transmitted from the transmitter 121, expands and filters through the magnifier (not shown). Compare with voltage phase comparison. In addition, another set of pulse waves and voltage values generated after comparing the standard clamp voltage generator signal (not shown in the figure) with the voltage phase difference is used as signal output data. The signal is processed by a micro processor (not shown), voltage analysis processing and calculation, and then the distance of infrared reflection can be calculated, so the chip height in the chip basket 16 can be detected safely and automatically. To do. Finally, a signal is displayed on the chip 26 by the lamp 26, and the lamp 26 displays the empty (remaining) capacity in the chip basket 16 in several stages, so that the user can display the current stage displayed on the lamp 26. The capacity of the tip basket 16 can be known clearly.

  When the chip basket 16 is full of chips, the micro processor (not shown in the figure) stops the operation of the cutter 20 and at the same time emits an alarm sound, for example. Prevents waste from overflowing.

  The infrared receiver / transmitter 12 starts to dynamically detect the height of chips inside the tip basket 16 after the cutter 20 stops. This is to prevent chips that are crushed and falling from affecting the accuracy of capacity calculation in the tip basket 16. The lamp 26 selects an LED set or an LCD liquid crystal display and other bright display devices, and dynamically detects and displays the storage space in the chip basket 16.

  The detailed description of the present invention according to the above embodiments does not limit the scope of the present invention. Even if a person familiar with the present technology makes changes or adjustments within the scope of the present invention, the important significance of the present invention is not lost and is included in the scope of the present invention.
