  By the way, when a film is wound around a roll bale with such a wrap machine, the operator winds the film by the set number of windings by pressing the button on the operation table. In this way, when counting the number of windings of the film, the rotation number of the turntable is detected by the rotation detection means provided below the turntable.

  However, when such a lap machine is stored, it is stored in a place where a large amount of grain is handled. Thus, a small animal such as a mouse may be gnawed and cause a failure. In such a case, the rotation is stopped when the worker feels an abnormality during lapping, but with this method, how many times the film is wound around the roll bale May not be understood, and the film may be wasted due to overwinding, or the film may be insufficiently wound and the crop may fall from the roll bale.

  Therefore, the present invention has been made paying attention to the above problems, and even when an abnormality occurs in the rotation detecting means for detecting the relative rotation state of the roll bale and the film, An object of the present invention is to provide a wrap machine capable of winding a film.

That is, the roll bale wrap machine of the present invention includes a bale support base that rotates the roll bale around a horizontal horizontal axis, a film unit that includes a film wound around the roll bale, and the bale support base. A rotating means for rotating the rolled bale or film unit relative to the longitudinal axis, a first rotation detecting means for detecting the number of rotations of the bale support or film unit rotated by the rotating means, and the rotation And a second rotation detecting means for detecting the rotation time of the bale support or film unit rotated by the means , storing the unit time required for one roll of film, and when the number of rotations is designated, set the time obtained by multiplying the unit time to the rotation speed as the rotation time of the second rotation detecting means, before When the rotation detection of the first rotation detection means and the second rotation detection means are activated at the same time and an abnormality occurs in the first rotation detection means, the rotation time is detected by the second rotation detection means. A specified number of rotations film is wound.

  In this way, even if an abnormality occurs in the first rotation detection means, the rotation state can be detected by the second rotation detection means that detects the rotation state in parallel with this, Overwinding and insufficient winding of the film can be solved.

Further, in such an invention, when the first rotation detecting unit cannot detect the number of rotations for a predetermined time or more, the remaining time is the unit time required for one roll of film from the last detected time. The second rotation detecting means can detect only the time multiplied by the number of rotations.

  In this way, since the time is counted from the time when the rotation is detected last, the error with respect to the number of windings can be reduced as compared with the case where the time is counted from the beginning.

According to the present invention, a bale support that rotates the roll bale around a horizontal horizontal axis, a film unit that includes a film wound around the roll bale, and a roll bale or film placed on the bale support Rotating means for rotating the unit relative to the longitudinal axis, a bail support that rotates by the rotating means or first rotation detecting means for detecting the number of rotations of the film unit, and bale support rotating by the rotating means A second rotation detecting means for detecting the rotation time of the table or the film unit, storing a unit time required for one roll of the film, and when the rotation number is designated, the unit time is set to the rotation number. set the time multiplied as rotation time of the second rotation detection means, said first rotation detection means and the second rotation detection When the rotation detection of the means is activated at the same time, and the first rotation detection means is abnormal, the rotation time is detected by the second rotation detection means, and the specified rotation number film is wound. Even if an abnormality occurs in the first rotation detection means, the rotation state can be detected by the second rotation detection means that detects the rotation state in parallel with this. The shortage can be resolved.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

Wrap machine 1 in this embodiment, be one obtained by the so wrapped film against Russia Ruberu 90, characteristically, the rotation of the vertical axis of the turntable 3 placing the bale 90 A first rotation detecting means 7a for detecting, and a second rotation detecting means 83 for detecting the rotation of the turntable 3 in the longitudinal direction by a detection method different from the first rotation detecting means 7a. When a rotation abnormality is detected by the rotation detection means 7a, the second rotation detection means 83 can perform winding for the number of turns corresponding to the remaining number of rotations. Hereinafter, the structure of the lap machine 1 in the present embodiment will be described in detail.

  First, in FIG. 1, reference numeral 2 denotes a base frame, which is provided with an elevating device 21 on a rectangular base frame 2 so that the turntable 3 placed thereon can be raised and lowered. It is. As for the lifting device 21, as shown in FIG. 2, an X link is provided inside a frame framed in a rectangular shape, and the turntable 3 is lifted and lowered by a hydraulic cylinder. By using such a lifting device 21, the roll bale 90 and the like can be discharged to a high place such as a truck.

  The turntable 3 supported on the elevating device 21 of the base frame 2 has a bail support 4 mounted thereon using a rotating means 31 such as a motor around a rotation axis in the vertical axis direction. It is made to rotate in a horizontal plane. On the front side of the frame that supports the turntable 3 and the rotation means 31, the first rotation detection means 7 a that detects the rotation of the bail support base 4 in the vertical axis direction is attached. The rotation of the bail support 4 can be detected when the detection body 71 approaches. In the present embodiment, a sensor such as a magnetic sensor, an optical sensor, a displacement sensor, or a position sensor can be used as the first rotation detecting means 7a. Therefore, it is preferable to use a magnetic sensor.

  Further, an inclination means 41 for inclining the turntable 3 toward the rear side is provided between the turntable 3 and the elevating device 21, and thereby provided on the turntable 3. In addition, the roll bale 90 can be loaded on the bale support 4. As such a tilting means 41, a hydraulic cylinder 43 that lifts the front side around a hinge 42 provided on the rear side (left side in the figure) is arranged below the turntable 3, and the hydraulic cylinder 43 The turntable 3 can be tilted rearward by extending.

The bail support 4 supported by the turntable 3 is configured so that a roll bale 90 can be placed thereon, and a belt is stretched on a roll attached to the frame body at a certain interval in the front-rear direction. The roll bale 90 placed on the rotator can be rotated about a horizontal rotation axis. A detecting body 71 such as a magnet constituting the first rotation detecting means 7a is attached below the frame of the turntable 3.

  The film unit 5 is configured such that a plastic film is wound around a roll bale 90 placed on the bale support 4 while extending a plastic film, and a support column 51 is erected from the rear side of the base frame 2. In this case, one or two film rolls are attached to the upper end. When two film rolls are attached, the film rolls are attached so as to be different from each other so that the film can be wound around the roll bale 90 having a wide area at a time while being stretched.

  On the other hand, a cutting mechanism 52 for cutting the film wound around the roll bale 90 is attached to the rear side of the bale support base 4, and the bale support base 4 is inclined toward the front, thereby cutting the cutter. The cutting mechanism 52 having the above is lifted upward so as to be cut by sandwiching the film. The cutting mechanism 52 is provided with a clamp mechanism for holding the film so that the film roll side of the cut film can be held.

  Further, the loading mechanism 6 picks up the roll bale 90 from the field and places it on the bale support 4 so that the roll bale 90 after wrapping can be discharged to the field or the like. This loading device includes a lift arm 61 erected from the base frame 2, a bail support arm 62 that bends in an L shape on the tip side of the lift arm 61, and a T-shape provided near the center of the lift arm 61. When the roll bale 90 in the field is loaded, the lift arm 61 is tilted horizontally using the tilting means 41 and the bale support arm 62 is brought close to the roll bale 90. Try to pinch. At this time, the T-shaped stopper 63 rotates around the fulcrum so as to escape from the roll bale 90 by a spring. Then, the roll bale 90 is placed on the bale placement table by rotating the lift arm 61 so as to stand up in that state. On the other hand, when the lapping is finished, the bail support 4 is tilted forward, transferred to the lift arm 61 while being sandwiched by the bail support arm 62, and the lift arm 61 is tilted to a horizontal state to roll it. Release the bale 90 to the field.

  In such a configuration, the operation of the control means 8 when performing lapping will be described with reference to the functional block diagram of FIG. 3, the time charts of FIGS. 5 to 6, and the flowchart of FIG.

The control means 8 is configured to control the rotation of the turntable 3 and the like. When the operation button 82 is pressed, the film is wound around the roll bale 90 by the number of rotations designated on the operation panel 81. . The operation panel 81 can set the number of windings for lapping as shown in the touch panel screen example of FIG. The storage unit 84 provided corresponding to the control means 8 stores a unit time for winding the film, and allows the operator to input the unit time using the operation panel 81. deep. Alternatively, the unit time may be stored in the storage unit 84 in advance, or the time required for one rotation detected by the first rotation detecting means 7a or the average value thereof may be stored as the unit time. You may keep it. Then, the control means 8 stores the time obtained by multiplying the number of turns by the number of turns by setting the number of turns, and the roll bale 90 is moved in the vertical and horizontal directions by pressing the operation button 82 by the operator (step S1). Thus, the film held by the cutting mechanism 52 is wound around the roll bale 90. At this time, the turntable 3 rotates about the vertical axis, and the detection body 71 crosses the first rotation detection means 7a, thereby counting the number of rotations (step S2 ) . Simultaneously with the pressing of the operation button 82, the time obtained by multiplying the designated number of rotations by the unit time is counted as the second rotation detecting means 83 (steps S3, S7 and FIG. 5).

Under such circumstances, when the cable of the first rotation detecting means 7a is broken or the mud adheres and the rotation state cannot be detected ("abnormality detection" in FIG. 5). ), the control unit 8 detects that the signal from a given time a first rotation detecting means 7a are not transmitted, thereby detecting an abnormality of the first rotation detecting unit 7a (step S 4). The “predetermined time” of this sensor abnormality is equal to or longer than the unit time required for one rotation of the turntable 3 stored in advance in the storage unit 84 and equal to or less than the time obtained by multiplying the rotation number by the unit time. And when abnormality of the 1st rotation detection means 7a is judged in this way (step S4 , Yes), it switches to the time of the 2nd rotation detection means 83 (step S7), and the time which passed the time. Then, the rotation of the turntable 3 is stopped (step S8). On the other hand, when no abnormality is detected, the rotation of the turntable 3 is stopped when the specified number of times has been counted (steps S5 and S6 ).

When an abnormality is detected in the first rotation detecting means 7a in this way, as shown in FIG. 6 , the time is elapsed from the timing when the abnormality was detected last, and the remaining time is detected. May be detected by the second rotation detecting means 83 by multiplying the number of rotations by unit time.

As described above, according to the above-described embodiment, the bale support 4 that rotates the roll bale 90 about the horizontal horizontal axis, the film unit 5 that includes the film wound around the roll bale 90, and the bale support Rotating means 31 for rotating the roll bale 90 placed on 4 around the vertical axis, first rotation detecting means 7a for detecting the rotation state of the bail support 4 rotated by the rotating means 31, and the rotation A second rotation detecting means 83 for detecting the rotation time of the bail support 4 rotated by the means 31 , storing unit time required for one roll of film, and when the rotation number is designated, set the time obtained by multiplying the unit time to the rotation speed as the rotation time of the second rotation detection means 83, the first rotation detecting unit 7a and the second rotation detecting means 83 When the rotation detection is started simultaneously, and the first rotation detection means 7a has an abnormality, the second rotation detection means 83 detects the rotation time and winds the specified rotation number film. Even when an abnormality occurs in the first rotation detection means 7a, the rotation state can be detected by the second rotation detection means 83 that detects the rotation state in parallel with this. As a result, overwinding or insufficient winding of the film can be solved.

Further, as the first rotation detecting means 7a, when the number of rotations cannot be detected for a predetermined time or more, the remaining number of rotations is multiplied by the unit time required for one roll of film from the last detected time. If the second rotation detecting means 83 can detect only the time, the error with respect to the number of turns can be reduced as compared with the case where the time is counted from the beginning.

  In addition, this invention is not limited to the said embodiment, It can implement in a various aspect.

  For example, in the above embodiment, the turntable 3 is rotated so that the film is drawn out from the fixed film unit 5 and wound. However, on the contrary, the film unit 5 is wound around the roll bale 90. The present invention can also be applied to a lap machine 1 that revolves.

  In the first embodiment, a magnetic sensor is used as the first rotation detection means 7a, and a timer for elapse of time is used as the second rotation detection means 83. Conversely, the first rotation detection means 7a may be a timer, and the second detection means may be a physical sensor such as a magnetic sensor. Alternatively, different types of physical sensors (such as a magnetic sensor and a displacement sensor) may be used.
