Description

Technical Field

[0001] The utility model relates to the technical field of machinery manufacturing, and particularly relates to a sorting device for signal sending pieces of a remote water meter. Background Art

[0002] The pointers of remote water meters are mostly plastic parts, and a half-width metal sheet needs to be coated on the upper surface of the plastic pointer. In this way, when the pointer rotates, the current of the NB remote module of the water meter can sense the half-width metal sheet, so as to generate a reading.

[0003] In the industry, the above-mentioned metal sheet is called a signal sending piece, and the signal sending piece is generally a thin iron sheet, which includes a semicircular main body and two left and right pin feet; the pointer includes a semicircular plate, a needle tip protrudes forward from the semicircular plate, a semicircular concave pit is sunken on the upper surface of the semicircular plate, a shaft sleeve for sleeving a pointer shaft is arranged on the lower surface of the semicircular plate, and two left and right concave notches are arranged on the side arc surface of the semicircular plate.

[0004] The process of assembling the signal sending piece and the plastic pointer in the prior art is as follows. First, the signal sending pieces and the pointers are respectively stacked in different areas on the workbench surface or placed in the material boxes on the left and right hands; then, a worker takes out a pointer and a signal sending piece, and places the semicircular main body of the signal sending piece into the semicircular concave pit of the pointer; then, one pin foot is bent down 90 degrees and clamped into the notch on the same side, and then bent inwards 90 degrees so that the end of the pin foot adheres to the lower surface of the semicircular plate; then, the other pin foot is bent down and inwards in the same step.

[0005] The above-mentioned assembly of the prior art has a drawback. Since the signal sending piece is very thin, only 0.1 mm, when it is stacked in batches in the material box or on the table, it is very difficult for the worker to accurately and quickly pick up a single signal sending piece with fingers. Especially when the signal sending piece adheres to the tabletop or the bottom of the box, it is even more difficult to pick up. Therefore, the operation is cumbersome and laborious, and the signal sending pieces in batches are scattered on the tabletop or in the material box, which occupies more space and looks very messy. Content of the Utility Model

[0006] The technical problem to be solved by the utility model is to provide a sorting device for signal sending pieces of a water meter, which can quickly, conveniently and accurately separate single signal sending pieces for manual picking, and make the storage of the signal sending pieces neat and orderly.

[0007] The technical solution of the present utility model is to provide a sorting device for water meter signal sending pieces, which includes a packaging cylinder with an upward opening. A cylinder cover is provided at the opening of the packaging cylinder, and multiple layers of signal sending pieces are stacked in the vertical cylinder cavity of the packaging cylinder. The sorting device includes a sorter, and the sorter is provided with a vertical feeding channel for reversely inserting and connecting the packaging cylinder with the cylinder cover removed in an inverted manner. A side discharge slit is provided on the side of the sorter, and the width of the side discharge slit is greater than the thickness of a single signal sending piece but less than the thickness of a double signal sending piece. The inlet of the side discharge slit is communicated with the lower end of the feeding channel. A hollow roller bin is provided below the feeding channel, and a roller for horizontally rubbing a signal sending piece at the bottom end of the feeding channel towards the outlet of the discharge slit is provided in the roller bin. The sorter is also provided with a servo motor, and the output shaft of the motor is connected to the roller. A sensor for sensing whether the signal sending piece located at the outlet of the discharge slit is taken away is provided at the discharge slit, and the sensor is signal-connected to the servo motor.

[0008] The working process of the sorting device is as follows. First, the upstream manufacturer of the signal sending pieces will stack the signal sending pieces full in the packaging cylinder and seal them with the cylinder cover. Therefore, the signal sending pieces provided to the assembly workers in the water meter factory are packaged in cylinders. The worker only needs to remove the cylinder cover and reversely insert the packaging cylinder with the opening facing down into the feeding channel of the sorter. Each signal sending piece in the packaging cylinder will fall due to its own weight, and the lowest signal sending piece will fall and abut against the roller. By driving the servo motor to drive the roller to rotate a fixed number of turns, the signal sending piece can be rubbed horizontally by a fixed distance, so that the front part of the signal sending piece just extends out of the outlet of the discharge slit, but the middle and rear parts of the signal sending piece are still located in the discharge slit and do not fall, so that the worker can take it. If the worker takes away the signal sending piece from the outlet of the discharge slit, the sensor will be triggered and notify the servo motor to output a fixed number of turns again, so that the next signal sending piece will be horizontally displaced by a fixed distance and reach the outlet of the discharge slit for the worker to take next time.

[0009] From the above analysis, it can be seen that the sorting device can quickly, conveniently and accurately sort and move the single signal sending piece to the discharge slit for the worker to take, thus facilitating the operation and improving the assembly efficiency of the worker. Moreover, the signal sending pieces are stacked and stored in the packaging cylinder, which occupies a small area, saves the workbench space, and the storage is neat and orderly.

[0010] Preferably, a through hole for the thimble to pass through is provided in the bottom wall of the encapsulation cylinder; the bottommost signal sheet closest to the cylinder cover is bonded to the side wall of the encapsulation cylinder by dispensing glue; the purpose of such a design is as follows. First, the signal sheet is light in weight and often gets stuck or adhered to the side wall of the encapsulation cylinder, resulting in material feeding jams. Workers use the thimble to pass through the through hole in the bottom wall of the cylinder and push down the stuck signal sheet to ensure smooth material feeding. Second, when the cylinder cover is opened and the encapsulation cylinder is inserted upside down into the blanking channel, the signal sheets may fall off in advance under the action of gravity and scatter everywhere. Therefore, by temporarily fixing the topmost signal sheet to the side wall of the opening of the encapsulation cylinder with dispensing glue, the problem of the signal sheets falling off in advance during the upside-down insertion can be avoided. Moreover, after the encapsulation cylinder and a stack of signal sheets are inserted upside down and in place, only by using the thimble to pass through the through hole and push down, the dispensing glue between the first signal sheet and the side wall of the encapsulation cylinder can be broken, enabling each signal sheet to fall normally and be smoothly pushed horizontally by the roller.

[0011] As a further preference, a stepped portion protrudes from the side of the sorter. The top surface of the stepped portion is flush with the lower edge of the discharge slit. An installation hole is provided in the top surface of the stepped portion, and a light sensor is provided in the installation hole. This structural design is reasonable, the sensor is convenient to assemble, and the sensor is sensitive and accurate in sensing. When the front part of the lowermost signal sheet is horizontally pushed out of the discharge slit by the roller, it just covers the light sensor, making the light flux zero. After people take away the signal sheet, the light flux above the sensor is restored. Therefore, the servo motor is accurately triggered to rotate a fixed number of turns to horizontally push the next signal sheet into place. Brief Description of the Drawings

The above-mentioned signal sending pieces 3 are stacked from the bottom wall of the packaging cylinder 1 to the cylinder cover 2. A through hole 4 for a thimble to pass through is provided on the bottom wall of the packaging cylinder 1; the signal sending piece 3 closest to the cylinder cover 2 in the packaging cylinder 1, that is, the highest stacked signal sending piece 3, is adhesively bonded to the side wall of the packaging cylinder 1 by dotting.

[0019] The sorting device includes a sorter 5. The sorter 5 is provided with a vertical blanking channel 6 for reversely inserting and connecting the packaging cylinder 1 with the cylinder cover 2 removed. In other words, the packaging cylinder 1 has the cylinder cover 2 removed and is reversely inserted and connected in the blanking channel 6. A side discharge slit 7 is provided on the side of the sorter 5. The width of the side discharge slit 7 is greater than the thickness of a single signal sending piece 3 but less than the thickness of a double signal sending piece 3; that is to say, the width of the discharge slit 7 is between one time and two times the thickness of a single signal sending piece 3. The entrance of the side discharge slit 7 is communicated with the lower end of the blanking channel 6.

[0020] A hollow roller bin 9 is provided below the blanking channel 6. A roller 8 for horizontally rubbing a signal sending piece 3 at the bottom end of the blanking channel 6, that is, the lowest positioned signal sending piece 3, towards the outlet of the discharge slit 7 is provided in the roller bin 9. The roller 8 is rotatably installed in the roller bin 9. The sorter 5 is also provided with a servo motor 10. The servo motor 10 is fixed on the side wall of the sorter 5, and the output shaft of the motor is connected to the roller 8.

[0021] A sensor for sensing whether the signal sending piece 3 located at the outlet of the discharge slit 7 is taken away is provided at the discharge slit 7. The sensor is signal-connected to the servo motor 10. Specifically, a stepped portion 5.1 protrudes from the side of the sorter 5. The top surface of the stepped portion 5.1 is flush with the lower edge of the discharge slit 7. An installation hole 12 is provided on the top surface of the stepped portion 5.1, and a light sensor 11 is provided in the installation hole 12.

[0022] Of course, the above structure is only the preferred embodiment of this application, and a series of changes are also allowed in the specific structure of this application. For example, the sensor can adopt an infrared sensor or a pressing pressure sensor; the through hole 4 may not be provided on the bottom wall of the packaging cylinder 1, and a stepped surface may not be provided outside the discharge slit 7, but a pressure sensor may be directly arranged at the lower edge of the discharge slit 7, and so on.
