In this apparatus, roll veils placed on the ground can be loaded and the wrapped roll veils can be raised and lowered by rotation, gripping and release of the loading arm.

  This loading arm is mounted on the body of the wrapping machine by a fulcrum shaft provided in the vicinity of the front end on one side, from a substantially upright position to a substantially horizontal position on one side of the front position of the bale support base. It is mounted so that it can rotate between.

  At the front end side of this loading arm, a gripping member is provided that holds the circumferential surface of the roll bale from the front, which is placed in a posture in which the axial direction is orthogonal to the longitudinal direction of the loading arm at the front position of the bail support base. On the base end side, a gripping member that holds the peripheral surface of the roll bale from the rear is provided.

  In addition, a support member at a position that supports the lower peripheral surface of one end in the axial direction of the roll bale when the roll bale is lowered in a posture in which the roll bale is lowered is disposed at an intermediate portion in the longitudinal direction of the loading arm. A stand-down unit is provided that switches to a position that deviates from the lower peripheral surface.

Japanese Patent No. 4036645

  Next, the unloading process of the unloading apparatus 2 will be specifically described.

<Roll bale loading process>
First step (FIGS. 1 and 2): The traveling device 1 is caused to travel with the roll bale support portion 3 in the standing state so that the loading arm 2A is in a parallel state and the axis of the unloading member 20C is parallel to the axis of the loading arm 2A. The roll bail support portion 3 faces the outer peripheral surface of the roll bale R and stops at a position where the outer peripheral surface of the first gripping member B contacts the outer peripheral surface of the roll bail R.

  Second step (FIGS. 3 and 4): The second holding member 2C is rotated in the roll bale holding direction, the rear outer peripheral surface of the unloading member 20C is brought into contact with the front outer peripheral surface of the roll bail R, and the first holding member The roll bale R is held by 2B and the unloading member 20C.

  Third step (FIGS. 5 and 6): The roll bale support 3 is tilted to erect the loading arm 2A, the held roll bale R is lifted from the field, and the roll bale support 3 is brought into a collapsed state. At the same time, the loading arm 2A is raised.

  Fourth step (FIG. 7): The second gripping member 2 </ b> C is rotated in the roll bale holding release direction, and the rear outer peripheral surface of the unloading member 20 </ b> C is separated from the front outer peripheral surface of the roll bale R. The holding is released and the roll bale R is moved onto the roll bale support 3.

  In a state where the roll bale R is supported on the roll bale support 3, the film F is wound around the roll bale R by the wrap film winding device 4 (not shown). The next roll bale unloading process is performed after this wrap film winding process.

<Roll bale unloading process>
First step (FIGS. 8 and 9): In a state where the roll bale support portion 3 is tilted, the third gripping member 2D is rotated in the roll bale holding direction so that the lower outer peripheral surface of the holding member 21D is above the roll bale R. Contact the outer peripheral surface. The second gripping member 2C that rotates with the rotation of the third gripping member 2D is such that the rear outer peripheral surface of the unloading member 20C and the rear outer peripheral surface of the support member 21C are in one half of the axial direction of the front outer peripheral surface of the roll bail R. Hold in contact. As a result, the roll bale R is held by the second gripping member 2C, the third gripping member 2D, and the roll bale support 3. At this time, the axial direction (longitudinal direction) of the unloading member 20 </ b> C and the axial direction (longitudinal direction) of the support member 21 </ b> C are perpendicular to the axial line of the roll bail R in the vertical direction.

  Second step (FIGS. 10 and 11): The roll bale R held down is brought close to the field by bringing the roll bale support 3 into an upright state and the loading arm 2A in a parallel state. In this state, the axial direction (longitudinal direction) of the loading / unloading member 20 </ b> C and the axial direction (longitudinal direction) of the support member 21 </ b> C intersect with the axial line of the roll bail R in the front-rear direction. Further, one axial half of the lower outer peripheral surface of the roll bail R is held so as to be placed on the unloading member 20C and the support member 21C, and the front outer peripheral surface is held by the rear outer peripheral surface of the holding member 21D. The roll bale R in this state is in contact with the roll bale support 3 and is held so as to be sandwiched between the roll bale support 3 and the third gripping member 2D. The roll bale R held in this way is in a state separated from the field with the axis parallel.

  Third step (FIGS. 12 and 13): The holding of the roll bale R is released by rotating the third gripping member 2D in the roll bale holding release direction. The roll veil R whose holding has been released is supported by a support member 21C at one half of the axial direction, and the opposite end is in contact with the field B with the support member 21C as a fulcrum.

  Fourth step (FIGS. 14 and 15): By tilting the roll bale support portion 3 and raising the loading arm 2A, the support member 21C lifts the lower half of the roll bail R in the axial direction, and this roll bale R Stand up. At this time, the support member 21 </ b> C that moves upward along with the standing operation of the loading arm 2 </ b> A slides while supporting the outer peripheral surface of the roll bale R, so that the roll bale R can be gradually raised. When the roll bail R stands up to a certain angle by the support member 21C, the axis rises up to the vertical state due to the weight of the roll bale R after this angle.

  Through the above steps, the roll bale R placed on the field can be loaded, wrapped, and the wrapped roll bale R can be erected and unloaded.

  According to such a wrapping apparatus A, when the roll bale R is loaded, the support member 21C is not brought into contact with the roll bale R, and the unloading member 20C and the first gripping member 2B in the second gripping member 2C are used. The roll bale R can be held and the roll bale R can be loaded without breaking. Therefore, the cylindrical shape of the roll bale R can be maintained, and the roll can be securely wrapped while maintaining this cylindrical shape. can do.

  When the roll bail R is unloaded, when the support member 21C supports the roll bale R, the roll bail R rotates integrally with the loading / unloading member 20C rotated by the expansion / contraction force of the cylinder 21A and moves to a position where the roll bale R is supported. Therefore, the roll bale R can be reliably supported, and the roll bale R can be unloaded while being raised, and the support member 21C is in contact with the roll bale R (supported state). Then, the support member 21C can be arbitrarily moved to a position where the support member 21C is not in contact with the roll bail R (a state where it is not supported).

  Further, since the second gripping member 2C and the third gripping member 2D rotate in the holding direction and the non-holding direction so as to hold and release the roll bale R, the rotation amount in the holding direction is reduced to the roll. By changing according to the diameter of the bail R, the roll bale R can be reliably held regardless of the diameter.

  Further, by rotating the second gripping member 2C and the third gripping member 2D in the non-holding direction to a position where they do not overlap with the roll bale support portion 3 in the front-rear direction, the first step in the roll bale loading step described above is performed. By being able to perform reliably and performing this 1st process reliably, the 2nd process in the above-mentioned roll bale loading process can be performed reliably.

  FIGS. 16-19 is a block diagram of the unloading apparatus 5 in the lapping apparatus which concerns on 2nd Embodiment of this invention. The loading / unloading device 5 is provided with the second gripping member 2C and the third gripping member 2D so as to rotate independently in the holding direction and the non-holding direction, respectively. In addition, description about the site | part which overlaps with the unloading apparatus 2 in the wrapping apparatus A is abbreviate | omitted by attaching | subjecting the same code | symbol, and only the unloading apparatus 5 vicinity is shown in figure.

  The loading / unloading device 5 includes two loading arms 2 </ b> A and 2 </ b> A ′, and is supported by the roll bale support 3.

The member 2D is supported.

  The support structure of the second gripping member 2C with respect to the loading arm 2A is the same as that in the first embodiment. The second gripping member 2C is supported by the connecting member 20A rotatably supported by the loading arm 2A, and the cylinder 21A. The second gripping member 2C is rotated by rotating the connecting member 20A by the link portion 22A.

  The support structure of the third gripping member 2D with respect to the loading arm 2A ′ is the same as the support structure of the second gripping member 2C with respect to the loading arm 2A, and the third gripping by the connecting member 20A rotatably supported by the loading arm 2A ′. The second holding member 2C is rotated by supporting the member 2D and rotating the connecting member 20A by the cylinder 21A and the link portion 22A.

  Next, the unloading process of the unloading apparatus 5 will be specifically described.
