Description

  The present invention relates to a horticultural binding machine, and more particularly, to a sag return mechanism of a binding tape in a horticultural binding machine that takes a slack of a binding tape before binding.

  A horticultural binding machine is a hand-held tool having a mechanism similar to a manual stapler, and is a tool for binding vines and branches of vineyard crops such as cocoons and peppers to a column or the like (see, for example, Patent Document 1).

  In the gardening binding machine, the driver handle and the clincher arm are opened and closed to perform the binding work. When the driver handle and the clincher arm are closed once, the stopper mechanism of the picking plate is released, and the picking plate pierces the binding tape drawn from the tip of the driver handle. When the driver handle and the clincher arm are opened, the binding tape is pulled out from the driver handle side, and the binding tape is stretched.

  Next, in this state, the horticultural tying machine is pushed forward to put crop vines and support posts between the driver handle and the clincher arm, and wrap the binding tape around them in a U-shape. Thereafter, when the driver handle and the clincher arm are closed, the leading end portion of the binding tape overlaps the subsequent portion to form a loop.

Next, by further closing the driver handle and the clincher arm, the overlapping portion of the binding tape is bound by the staple loaded in the magazine portion, and the binding tape is cut by the cutter blade. When the driver handle and the clincher arm are opened, the bundling process for one cycle is completed.
JP 2003-341613 A

  However, when the object to be bundled is pushed around the bundling tape stretched between the driver handle and the clincher arm and hung around, if the bundling machine is pushed too far, the bundling tape will be pulled out excessively and the bundling tape will sag. Thus, there is a problem that a gap is generated between the object to be bound and the binding tape at the time of binding, and the objects to be bound after binding are easily displaced.

  Conventional horticultural binding machines are not equipped with a mechanism to rewind the binding tape once pulled out, and if the binding is likely to be insufficient due to the slack of the binding tape, the same portion is bound again. There was no more way.

  The present invention has been made in order to solve the above-described problems, and even in the case where slack of the binding tape occurs before binding in the gardening binding machine, the binding tape that has been drawn out is unwound and bound. It is an object of the present invention to provide a slack return mechanism of a binding tape in a horticultural binding machine, which can be stopped by removing the slack of the binding tape before removing the gap between the object to be bound and the binding tape. To do.

  In order to solve the above-mentioned problem, the invention according to claim 1 is provided such that a tape reel storing a bundling tape is provided in a driver handle of a stapler, and a tension is provided between the tip of the driver handle and a clincher arm from the tape reel through a tape path. By hanging the bound binding tape around the object to be bound and closing the driver handle and the clincher arm, the magazine portion of the driver handle and the tip of the clincher arm come into contact with each other so that the tip of the binding tape overlaps the subsequent portion. In a horticultural binding machine for binding by a staple and cutting a binding tape by a cutter blade provided on a driver handle, a driving roller and a driven roller for sandwiching the binding tape from both sides are provided in a tape path provided in the driver handle, and the driving roller Rotate the binding tape in the direction opposite to the feed direction. Characterized thereby moving.

  The invention according to claim 2 is characterized in that the operating means of the driving roller is disposed within a range where the finger reaches when the operating means of the driving roller is bound.

  According to a third aspect of the present invention, a driving roller and a driven roller capable of sandwiching the binding tape from both sides are provided in the tape path, and the driven roller is provided so as to be able to contact and separate from the driving roller, and in the separating direction. The clincher arm and the driving roller are operatively connected to each other via a conversion mechanism that converts the vertical movement of the clincher arm into a rotational movement of the driving roller that is reversely rotated with respect to the binding tape feed. And

  The invention according to claim 4 is characterized in that the operation means of the driven roller is arranged within a range where the finger reaches the operation means of the driving roller when bound.

  The invention according to claim 5 is characterized in that a knob for manual rotation is provided on the tape reel, and the tape reel can be rotated in the direction opposite to the binding tape feeding direction by this knob.

  According to the first aspect of the present invention, in the operation of binding the vines and branches of the vine crops to the support column, even if the binding tape is pulled out excessively, the driving roller is rotated to bind the binding tape. By moving the binding tape in the direction opposite to the feeding direction, the binding tape moves back in the direction opposite to the feeding direction, so that the deflection can be easily taken, so that the binding tape is brought into close contact with the object to be bound. And a good binding state can be obtained.

  According to the second aspect of the present invention, since the operating means of the driving roller is disposed within the reach of the finger of the hand that is performing the bundling operation, the tape can be returned with one hand. Good.

  According to the invention of claim 3, when the driven roller is pressed against the drive roller, the binding tape is sandwiched between the two rollers, and the clincher arm is moved in the vertical direction, the drive roller feeds the binding tape through the conversion mechanism. Since it is converted into a rotational motion that rotates in the direction opposite to the direction, the binding tape is returned to the tape reel side, and the slack of the binding tape can be removed. After that, if the above operation is continued, a bundling without slack can be realized.

  According to the invention of claim 4, since the operating means of the driven roller is disposed within the range where the finger of the hand of the bundling work can reach, the tape can be returned with one hand, so that the operability is improved. Good.

  According to the fifth aspect of the present invention, the tape reel can be directly rotated in the direction opposite to the bundling tape feeding direction by picking, so that the structure is simplified and the cost can be kept low.
