Description

  The present invention relates to a multi-film winding and collecting machine, and more specifically, a winding drum is mounted on a self-propelled machine that travels along a work path sandwiched between scissors, and the multi-film covered with the scissors is wound. In a collecting machine that winds and collects on a take-up drum, the multi-film wound on the take-up drum can be wound smoothly and evenly wound around the take-up drum.

Conventionally, for the work to peel off and collect the multi-film coated on the straw that grows vegetables, fruits, flowers, etc., the multi-film is collected by winding the multi-film on the take-up drum mounted on the machine body. Winding and collecting machines are widely used.
In the collection work using this multi-film take-up and recovery machine, if the multi-film is biased and wound around the take-up drum, the amount collected in one collection work will be greatly reduced. The operator moved directly by hand so as not to cause a bias in winding.

  However, if the worker tries to manually move the multi-film to be collected as described above, there is a problem that dust and mud attached to the multi-film are scattered and the worker becomes dirty. May be caught in the take-up drum.

In order to solve the above problem, the present applicant has previously provided a multi-film winding and collecting machine 1 shown in FIG. 6 in Japanese Patent Laid-Open No. 2002-284403 (Patent Document 1). The winding and collecting machine 1 is provided with an adjusting unit 3 for restricting a winding position to the winding drum 2 through the multifilm F to be collected in front of the winding drum 2. Thus, the bias of the multi-film F taken up by moving in the axial direction of the take-up drum 2 is prevented.
This eliminates the need for an operator to manually move the multi-film to prevent the multi-film from being biased, and allows the multi-film winding operation to be performed easily and safely.

  However, in the winding / collecting machine 1 provided in Patent Document 1, the alignment handle 4 for operating the adjusting unit 3 is provided at the front position of the machine body. When collecting, the operator is usually located at the rear in the traveling direction, and there is a problem that the alignment handle 4 is difficult to operate or cannot be operated from the rear side.

  Furthermore, when a multi-film collecting machine is mounted on the machine that travels on the work path sandwiched between the cages, various problems occur when the multi-film is pulled obliquely from the left and right cages and wound around the take-up drum. . For example, when slack occurs in one of the multi-films due to the difference in length between the left and right multi-films, it becomes difficult for the traveling machine to meander to the other that is strongly pulled, and to go straight on the work path. Moreover, it is very difficult to wind and collect the left and right multi-films on the outer peripheral surface of the winding drum at the same time with a substantially uniform thickness.
