[0001]

BACKGROUND OF THE INVENTION The present invention mainly uses a plastic film around the outer periphery of a roll bale in order to ripen a pasture roll bale that has been cut down in a field and wound into a roll by a roll baler to form a high-quality silage. In a roll bale wrapping machine used for winding and packaging, the present invention relates to an improvement in an automatic stop device for stopping a winding operation when the winding of a plastic film around a peripheral surface of a roll bale reaches a predetermined number of windings.

[0002]

2. Description of the Related Art A conventional wrapping machine A for winding a plastic film around the outer periphery of a pasture roll bale formed by winding into a roll is as follows.
As shown in FIGS. 1 to 3, first, a rotary table 2 that rotates with a vertical rotation axis w is mounted on a machine frame 1, and the rotary table 2 is driven and rotated by a vertical rotation shaft thereof. The drive mechanism a is linked. A plurality of endless belts 4 are mounted on the upper surface of the turntable 2 such that a plurality of endless belts 4 are rotated parallel to each other with a horizontal rotation axis. Are wound in parallel so as to rotate endlessly along their outer peripheral surfaces by the rotation of the rollers 3, and the upper peripheral surface side of the endless belts 4 in parallel is mounted on the mounting table z of the roll bale B. The endless belts 4... That form the mounting table z form the rotary table 2 by a driving mechanism a.
Of the rollers 3 around which the endless belt 4 is wound so as to simultaneously drive endlessly in one direction when rotated by the driving of the drive mechanism a to the drive mechanism a. (Not shown). In addition, the machine frame 1 has a width around a rotary table 2 on which the mounting table z is provided on the upper surface side and a portion located on the side of the roll bale B mounted on the mounting table z. A film feeding device 5 for feeding a wide tape-like plastic film F (or an extensible plastic film) from a bundle thereof is arranged and supported on the machine frame 1.

[0003] As a result, as shown in FIG. 3, the roll bale B is placed on the upper surface of the mounting table z in a sideways posture in which the axis of the roll bale is in a horizontal direction. With the end portions of the plastic film F pulled out from the bundle of the plastic films F loaded in the film feeding device 5 being linked, the endless belts 4 are rotated while the rotary table 2 is rotated by the driving mechanism a. Is rotated, the roll bale B having the above-described posture is rotated.
Is rotated by the rotation of the rotary table 2 with a vertical rotation axis w which is a direction orthogonal to the axis of the roll bale B, whereby the plastic film F fed from the film feeding device 5 is rotated by the roll bale B. Is wound around the outer peripheral surface of the mounting table z in a direction parallel to the axis, and the roll bale B idles on the mounting table z by simultaneously rotating the endless belts 4 constituting the mounting table z. By slowly rotating around the axis of the axis, the winding position of the plastic film F with respect to the outer peripheral surface of the roll bale B is sequentially displaced in the circumferential direction of the roll bale B. A plastic film F is wrapped around the periphery to be in a packaged state.

The wrapping machine A wraps the plastic film F around the outer periphery of the roll bale B. The roll bale B rotates once around the center of the axis on the mounting table z, so that the plastic film F is doubled. At this point, the power transmission control device b, which controls the power transmission to the drive mechanism a on and off, is turned off by the operation of the operation lever c, and the winding operation is completed. However, in order to mature the high-quality silage, usually, the roll bale B is further rotated one turn on the mounting table z, and at the time of the quadruple winding, the operating lever c is operated to rotate the drive mechanism a. The power transmission control device b for turning on and off the power transmission is turned off, and the turntable 2
The rotation of the endless belts 4 is stopped, the winding operation on one roll bale B is completed, a new roll bale B is replaced, and the power transmission control device b is turned on by operating the operation lever c. We are starting to wind again.

The control operation for turning off the drive mechanism a for ending the winding operation on the one roll bale B is performed on the plastic film F to be wound.
Marking is performed by color spraying, and when the mark becomes invisible, it is determined that winding has been completed to a predetermined number of turns. At that time, the manual operation of the operating lever c turns off the drive mechanism a. A power transmission control device using a hydraulic circuit, which counts the number of rotations of the rollers 3 for rotating the endless belts 4 using an electric circuit, and when the total number of rotations of the rollers 3 reaches a predetermined number. Is operated to automatically turn off the drive mechanism a.

[0006]

In the wrapping machine A, the control means for counting the number of windings of the plastic film F wound on the outer peripheral surface of the roll bale B and terminating the winding operation is manually controlled based on visual observation. In the means for performing, it is necessary to perform an operation of marking with a color spray every time the plastic film F is wound around once, and it is troublesome, and it is necessary to constantly watch the peripheral surface of the roll bale B. There's a problem. Also,
In the means for automatic control using an electric device, a power supply is absolutely necessary for the detecting means for detecting the number of rotations of the photoelectric tube or the like, and therefore, every time the roll bale B is replaced,
There is a problem that an operation of the automatic stop device is required separately, such as an operation of turning on / off a power switch and a reset of a counter, thereby increasing the number of operation steps. In addition, there is a problem that many troubles occur in the electric wiring and the like. Furthermore, the automatic stop device using an electric device is very expensive due to its high cost, so it is sold separately as an option. There are problems that make it difficult to use.

The present invention has been made to solve these problems which have occurred in the conventional means. A wrapping machine A has a plastic film F on a peripheral surface of a roll bale B with a predetermined number of turns. When wound up
A new means for accurately detecting it and automatically stopping the drive mechanism a by an inexpensive mechanical means with a simple mechanism without using any electrical means. The purpose is to provide.

[0008]

The actuating member c is driven through a plastic film F fed by the rotation of the turntable 2 to rotate the rubber roll shaft of the film feeding device 5 serving as a rotation shaft S that rotates at a predetermined rotation speed. Use
In response to the increase in the cumulative number of rotations of the rotating shaft S, the drive mechanism a was driven via a speed reduction mechanism so as to move toward a position where the drive mechanism a was turned off. When the number of rotations reaches a desired value in relation to d, the stop operation member d moves to the operation position where power transmission to the drive mechanism a is turned off, and the power transmission control device is turned off. And the operation of the rollers 3 is automatically stopped to end the winding operation.

The present invention proposes an automatic stop device in a veil wrapping machine, and also mounts a rotary table 2 that rotates with a vertical rotation axis w by a driving mechanism a on a machine frame 1.
