Abstract

<P>PROBLEM TO BE SOLVED: To provide a winder capable of operating an operation rod with high operability, while avoiding an obstruction on an orbit just under a rotary input shaft. <P>SOLUTION: In this winder, the rotary input shaft 5 is rockably supported in one direction by a hinge part 6, to thereby prohibit rocking in both side direction of a casing 2. When the hinge part 6 is put in a twofold state, the rotary input shaft 5 and a second shaft 42 mutually become an attitude on a concentric shaft even in winding and rewinding work, and the operation rod 49 and the rotary input shaft 5 become an attitude in the vertical direction by weight of the operation rod 49. While, when the obstruction exists in the front vicinity of a vinyl house, the operation rod 49 in the vertical direction is inclined in the direction for separating from the vinyl house. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a winder for winding a sheet-like member.

  In the vinyl house for agriculture, in order to adjust the temperature and humidity in the house appropriately according to the crops and other plants to be grown, a ventilation opening is provided in an appropriate part of the roof of the vinyl house, and this ventilation opening A house ventilator is provided that includes a sheet material that covers the part in an openable and closable manner, and a winder for winding the sheet material (see, for example, Patent Document 1).

  FIG. 13 is an explanatory diagram for explaining how the conventional winder is used. In FIG. 13, reference numeral 101 denotes a roof portion of a bowl-shaped vinyl house 100. The roof portion 101 has a plurality of arch-shaped roof pipes 102, 102,... Standing in the longitudinal direction of the vinyl house 100 at appropriate intervals, and a sheet is placed on the roof pipes 102, 102,. The roof pipes 102, 102,... Are connected and fixed to a plurality of pipes arranged in the longitudinal direction of the vinyl house 100. A ventilation opening 103 for ventilating the inside of the vinyl house 100 is provided in a substantially central region of the roof portion 101, and the ventilation opening 103 is an opening / closing sheet material 105 wider than the ventilation opening 103. It can be coated by. The upper edge of the opening / closing sheet material 105 is fixed to a pipe near the ventilation opening 103 using a fixture (not shown), and the lower edge of the opening / closing sheet material 105 is fixed to the vinyl house 100. A fixing tool (not shown) is fixed to the opening / closing rod 50 arranged in the longitudinal direction.

  One end side of the opening / closing rod 50 is appropriately extended from the front surface (wife surface) of the vinyl house 100, and a winder 110 for winding the opening / closing sheet material 105 is connected to one end of the opening / closing rod 50. It is fixed.

  The winder 110 includes a three-dimensional shell-shaped casing 112 having an inverted pulley outer edge when viewed from the front, and a rotary input shaft 115 to which a rotational driving force in the forward and reverse directions is applied from the center of the bottom surface of the casing 112. , And projecting so as to be orthogonal to the bottom surface of the housing 112. An operation rod 49 is connected to the rotation input shaft 115 through a coupling portion 118 so as to be rotatable by 360 ° around the central axis of the rotation input shaft 115.

  The coupling portion 118 includes an end-size cylindrical coupling cylinder member 119. The inner diameter of the coupling cylinder member 119 is slightly smaller than the outer diameter of the rotary input shaft 115 and the outer diameter of the operation rod 49 described above. It is enlarged. In the vicinity of one end of the coupling cylinder member 119, a first bolt for connecting to the rotary input shaft 115 is detachably attached so as to penetrate the coupling cylinder member 119 in the diametrical direction. In the vicinity of the other end, the second bolt for fixing the operating rod 49 can be tightened and loosened at a position facing the circumferential direction of the coupling cylinder member 119 so that the legs of both the second bolts penetrate the peripheral wall. Screwed.

  In the vicinity of the tip of the rotary input shaft 115 described above, a through-hole having a drum shape in a longitudinal sectional view and penetrating the rotary input shaft 115 is opened in a direction perpendicular to the central axis of the rotary input shaft 115. Then, after fitting one end of the coupling cylinder member 119 to the tip of the rotary input shaft 115 with the first bolt removed, the cup is passed through the through hole of the rotary input shaft 115. The coupling cylinder member 119 is connected to the rotation input shaft 115 by being attached to the ring cylinder member 119. The operating rod 49 is connected to the coupling cylinder member 119 by fitting the tip of the operation rod 49 into the other end of the coupling cylinder member 119 and screwing in the second bolts.

  At this time, since the through-hole opened in the rotation input shaft 115 has a drum shape in a longitudinal sectional view, both ends of the first bolt connecting the coupling cylinder member 119 and the rotation input shaft 115 are at the center of the through-hole. Therefore, the coupling cylinder member 119 can rotate 360 ° around the central axis of the rotary input shaft 115 with the central axis thereof intersecting with the central axis of the rotary input shaft 115. ing.

  The rotational drive applied from the operating rod 49 to the rotary input shaft 115 as the vertical axis through the coupling portion 118 is in a direction orthogonal to the rotary input shaft 115 via the bevel gear disposed in the housing 112. It is transmitted to a rotary output shaft which is a horizontal axis disposed in the.

  By the way, the rotary input shaft 115 described above has a double cylinder structure, and the rotational drive applied to the rotary input shaft 115 by the action of a stopper spring member disposed between both cylinders is a cylindrical rotation output. Although it is transmitted to the shaft, the rotational drive given to the rotation output shaft is not transmitted to the rotation input shaft 115.

  On the other hand, the distal end portion of the rotation output shaft protrudes from the upper center of the rear surface of the housing 112 so as to be orthogonal to the rear surface of the housing 112, and the opening / closing rod 50 described above is disposed at the distal end portion of the rotation output shaft. One end of each is internally fitted and fixed. Then, the winder 110 rotates the open / close rod 50 forward and backward by rotating the rotation output shaft, thereby moving the open / close rod 50 and the winder 110 over the roof pipes 102, 102,. The opening / closing sheet material 105 is wound around the opening / closing rod 50 while being moved in a direction perpendicular to the longitudinal direction of the opening / closing rod 50, or the opening / closing sheet material 105 is rewound from around the opening / closing rod 50. 103 was opened and closed.

  By the way, when the tip of the operation rod 49 is directly connected and fixed to the tip of the rotation input shaft 115, the operation rod 49 cannot pass through a track other than directly below the rotation input shaft 115. Therefore, when the user opens / closes the ventilation opening 103, the user must operate the operation rod 49 while avoiding the obstacle, which makes opening / closing work difficult. However, when the rotation input shaft 115 and the operating rod 49 are connected via the coupling part 118 as described above, even if there is a failure under the track, the user can operate the operating rod with the coupling part 118. By tilting 49 away from the vinyl house 100, the operating rod 49 can be operated at a position away from the obstacle.

  However, such a conventional winder has the following problems. That is, when the opening / closing sheet material 105 is wound around the opening / closing rod 50 by the winding machine 110, the force that the opening / closing sheet material 105 tries to unwind is wound via the opening / closing rod 50. Since the winder 110 tries to rotate around the central axis of the opening / closing rod 50, the operation rod 49 connected to the winder 110 acts so as to prevent the winder 110 from rotating. The winder 110 is held in a posture in which both actions are balanced, that is, in a posture in which the tip of the rotary input shaft 115 is rotated by an appropriate angle from the vertical direction to the center in the width direction of the vinyl house 100.

  On the other hand, since the operation rod 49 is connected to the winder 110 via the coupling portion 118, the posture in the substantially vertical direction is maintained regardless of the posture of the winder 110. Therefore, when the operating rod 49 is rotated, it must be performed in a state where the central axis of the operating rod 49 and the central axis of the rotary input shaft 115 intersect with each other, and therefore, a rotational driving force is applied from the operating rod 49 to the rotary input shaft 115. It is difficult to convey smoothly and the operability when rotating the operation rod 49 is low.

  However, if there is a failure on the trajectory directly below the rotary input shaft 115, it is also important to avoid this.

The fixed portions of the base 33 and the second support portion 62 are covered with the casing 2 described above. The second shaft 42 passes through the bottom 35 of the base 33, the second support 62, the housing 2, and the first support 61, and the first support 61 of the hinge 6 that is folded in half. From the above, it is protruded by a suitable size. A through hole 44 that penetrates through the second shaft 42 and extends in the axial direction of the second shaft 42 is formed at the tip of the second shaft 42.

  On the other hand, a long hole 64 that is long in the direction orthogonal to the axial length direction of the pivot portion 63 is formed at the approximate center of the first support portion 61, and the head portion 54 of the rotary input shaft 5 is formed in the long hole 64. It is allowed to rotate freely.

  The inner diameter of the head portion 54 is larger than the inner diameter of other portions of the rotary input shaft 5, and the outer diameter of the head portion 54 is slightly smaller than the shorter diameter of the long hole 64. The thickness of the portion near the opening end of the head portion 54 is larger than the thickness of the other portion of the head portion 54, and the outer diameter of the thick portion 55 is the short diameter of the long hole 64. It is bigger. In addition, an annular stopper member 56 is externally fitted and fixed at a position on the outer peripheral surface of the head portion 54 at an appropriate distance from the thick portion 55, and the stopper member 56 and the thick portion 55 The long hole 64 is positioned between them to prevent the head portion 54 from being pulled out of the long hole 64.

  The inner diameter of the head portion 54 is appropriately larger than the outer diameter of the second shaft 42, and the tip end portion of the second shaft 42 is inserted into the head portion 54. On the circumferential surface of the thick portion 55 of the head portion 54 described above, fitting holes for fitting both ends of the rod-like connecting pin 8 are provided facing each other at different positions by 180 ° in the circumferential direction. By inserting both ends of the connecting pin 8 slidably inserted in the through hole 44 of the two shafts 42 in the axial length direction of the second shaft 42 into the both fitting holes, the rotary input shaft 5 and the second shaft The shaft 42 is connected.

  As a result, the forward / reverse rotational force applied to the rotation input shaft 5 by operating the operation rod 49 causes the second shaft 42, the first shaft 41, the second bevel gear 32, the first bevel gear 31, and the rotation output shaft 7. The opening / closing rod 50 connected to the rotation output shaft 7 is rotated forward and backward. On the other hand, a rewinding force is applied to the opening / closing rod 50, but is not transmitted to the second shaft 42 and the rotary input shaft 5 as described above by the action of the one-way clutch 43.

  By the way, the rotation input shaft 5 is connected to the base 33 of the winder main body 3 by the hinge portion 6 as described above, while the connection pin 8 passes through the through hole 44 of the second shaft 42 and the shaft of the second shaft 42. Since the rotation input shaft 5 is slidably inserted in the longitudinal direction, the rotary input shaft 5 is swung to the front side of the housing 2 until the connecting pin 8 comes into contact with the proximal end side of the through hole 44 of the second shaft 42. Can do.

  On the other hand, since the rotary input shaft 5 is supported by the hinge portion 6 so as to be swingable in one direction as described above, the rotation input shaft 5 is prohibited from swinging in both directions of the housing 2 and the hinge portion 6 is folded in two. In this state, even during the winding / unwinding operation, the rotary input shaft 5 and the second shaft 42 are coaxial with each other, and the operation rod 49 connected to the rotary input shaft 5 can be operated with high operability. Can be operated.

  By the way, the diameter of the head portion 54 described above is made as small as possible. Therefore, when the rotary input shaft 5 is swung, the connecting pin 8 contacts the proximal end side of the through hole 44 of the second shaft 42. Before, the tip of the second shaft 42 may come into contact with the inner surface of the head portion 54.

  FIG. 4 is a cross-sectional view taken along line IV-IV of the winder shown in FIG. 3 and shows the long hole 64 and the head portion 54 of the first support portion 61.

As shown in FIG. 4, the long hole 64 of the first support portion 61 has a long axis in a direction perpendicular to the axial direction of the pivot portion 63 of the hinge portion 6, and the head portion 54 has a length of the long hole 64. It can slide more than the required dimension in the axial direction.

  Accordingly, when the rotation input shaft 5 is swung so that the connecting pin 8 contacts the proximal end side of the through hole 44 of the second shaft 42, the tip of the second shaft 42 contacts the inner surface of the head portion 54. The rotary input shaft 5 can be swung until the connecting portion 8 comes into contact with the proximal end side of the through hole 44 of the second shaft 42 by sliding the head portion 54 in the direction away from the pivot portion 63. As a result, the tip of the second shaft 42 is prevented from coming into contact with the inner surface of the head portion 54, and even when the rotary input shaft 5 is swung, the load increases when the operation rod 49 is operated. This is suppressed as much as possible.

  On the other hand, since the diameter of the head portion 54 that requires strength can be reduced as much as possible, the head portion 54 can be reduced in weight, and the material cost can be reduced.

  As described above, when the rotary input shaft 5 is rotated forward and backward via the operation rod 49, the winder 1 transmits this rotational driving force to the rotational output shaft 7 and opens and closes by rotational driving of the rotational output shaft 7. The opening / closing rod 50 and the winder 1 are moved in the direction orthogonal to the longitudinal direction of the vinyl house 100 on the roof pipes 102, 102,. The opening / closing sheet material 105 is wound up or the opening / closing sheet material 105 is rewound from the opening / closing rod 50 to open and close the ventilation opening 103.

  At this time, since the rotation input shaft 5 is supported by the hinge portion 6 so as to be swingable in one direction, the rotation input shaft 5 is prohibited from swinging in both directions of the housing 2. Even during the winding / rewinding operation, the rotation input shaft 5 and the second shaft 42 (see FIG. 3) are in a concentric posture with each other. The rotation input shaft 5 has a vertical posture. Therefore, the operation rod 49 can be smoothly operated with high operability.

  On the other hand, when there is an obstacle such as a side groove in the vicinity of the front of the vinyl house 100, the operation rod 49 is moved away from the obstacle by tilting the operation rod 49 in the vertical direction away from the vinyl house 100. Can be operated.
