And a take-out mechanism 40 that feeds out the stored roll sheets 2, 2,.
Further, as shown in FIG. 1B, the roll sheet 2 is obtained by winding a sheet material 6 around a central portion of the core material 3, and has step portions 4 and 4 having outer diameters larger than those of the core material 3 at both ends. Is provided.

  Next, as shown in FIG. 2 (a), the winding mechanism 8 is attached to the left and right ends at the upper stage of the frame 50, and the bracket 13 clamps the three bearings 9, 10, 11 in a rotatable state. 14 and recesses 52 and 52 that hold the shaft portion of the handle 7 when the handle 7 is inserted into the shaft hole 5 of the core member 3 as shown in FIG.

  Further, as shown in FIG. 3, the misalignment prevention mechanism 15 includes height adjustment bolts 17 and 18 for adjusting the left and right heights relative to the guide arm 16 in which rods are combined in an inverted H shape, and the bracket 13. It is comprised with the support plate 12 on the semicircle standing upright to the side.

  In addition, as shown in FIG. 4A, a feed mechanism 25 is provided at the subsequent stage of the winding mechanism 8, and the guide arm 16 that rotates around the shaft portion 26, As shown in FIG. 4 (b), the roll lever 2 receives the roll sheet 2 in conjunction with the operation of the guide arm 16 and rotates around the rotation shaft 21, as shown in FIG. 19.

  In addition, as shown in FIG. 5A, the tilt prevention mechanism 29 is provided with star-shaped rotating plates 31 and 31 at both ends of the support link 30, and at the lower ends of the rails 53 and 53, the rotating plates 31 and 31 are This is a structure that rotates in the direction indicated by the arrow in FIG.

Next, as shown in FIG. 6A, the clogging prevention mechanism 35 is provided with a guide rail 36 curved in an L shape on the back side of the lower ends of the left and right rails 53, 53, and at a constant interval from the lower end of the rail 53. The guide rail 37 is provided in a vertically standing state on the upper end side of the rails 54 and 54, and an inclined surface 38 is provided at the lower end of the guide rail 37.
In addition, as shown in FIG. 3, a guide rail 55 and a guide rail 56 having an inclined surface 57 formed at the lower end are provided between the rails 54 and 60. A guide rail 62 and a guide rail 63 having an inclined surface 64 formed at the lower end are provided between the rails 60 and 61, and an inclined surface 64 is provided at the lower end of the guide rail 63. Yes.

  Next, as shown in FIG. 7A, the take-out mechanism 40 provided on the front end side of the rail 61 rotates according to the rotation of the handle 43 in the direction indicated by the arrow, as shown in FIG. A fishhook-like sheet stopper 41 rotates around an arm 42.

The winding, storing and laying of the sheet material 6 by the sea track 1 configured in this way are performed as follows.
First, the step portions 4 and 4 of the core material 3 are placed between the left and right bearings 9, 10, and 11 of the sea track 1 shown in FIG. 8. As a result, the core material 3 is held in a horizontal state by the winding mechanism 8 and can rotate between the left and right bearings 9, 10, 11.
Thereafter, the shaft portion of the handle 7 is inserted into the shaft hole 5 of the core member 3 shown in FIG. As a result, as shown in FIG. 2 (b), the shaft portion of the handle 7 is sandwiched by the notch of the recess 52, and when the handle 7 is rotated, the cores 3, 3 are accordingly moved to the left and right bearings 9, It will rotate between 10 and 11.

  Next, one end of the sheet material 6 laid on the floor or the like is attached to the shaft portion of the core material 3. At this time, as shown in FIG. 8, the sheet material 6 is passed between the rods formed in the inverted H shape of the guide arm 16 from the state of passing through the frame of the support arm 20, and then the shaft of the core material 3. Attach to the part. When the handle 7 is rotated in this state, the laid sheet material 6 is wound around the core material 3, whereby the roll sheet 2 is formed.

Here, prevention of the positional deviation of the sheet material 6 by the positional deviation prevention mechanism 15 is performed as follows.
When the sheet material 6 is wound by the sea track 1, the sheet material 6 is greatly affected by the state in which the sheet material 6 is laid on the floor surface. Therefore, the rotation direction of the winding mechanism 8 and the longitudinal direction of the sheet material 6 are aligned in the same direction. Although necessary, it is difficult to perfectly match these orientations.
On the other hand, the sheet material 6 is distorted in a certain direction in advance, and this distorted state is corrected thereafter, so that the positional deviation is generated when the roll sheet 2 is formed by winding the sheet material 6. It becomes possible to prevent.
Specifically, among the height adjustment bolts 17 and 18 that adjust the left and right heights of the guide arm 16 shown in FIG. 3, the height adjustment bolt 17 is adjusted to be higher than the height adjustment bolt 18. The guide arm 16 is inclined from the height adjustment bolt 17 side to the height adjustment bolt 18 side. Then, since the sheet material 6 moving on the guide arm 16 moves along the inclination of the guide arm 16, the sheet material 6 is distorted in the same direction. When the side surface of the sheet material 6 is brought into contact with the support plate 12 in this state, the roll sheet 2 without misalignment is formed by correcting the distortion.

Thereafter, the shaft portion of the handle 7 inserted into the shaft hole 5 is pulled out, and as shown in FIG. 4A, when the guide arm 16 of the feed mechanism 25 is rotated around the shaft portion 26 in the clockwise direction indicated by the arrow, The left and right shaft portions of the guide arm 16 abut on the portion of the core material 3 where the sheet material 6 is not wound, and the roll sheet 2 moves backward from the winding mechanism 8 as shown in FIG. It will be pushed up.
At this time, the roll lever 2 that moves on the guide arm 16 by the lock levers 19 and 19 contacting the guide arm 16 rotating in the counterclockwise direction indicated by the arrow about the rotation shafts 20 and 20 is the core material. 3 and 3 are received in contact with the lock levers 19 and 19.
Then, as shown in FIG. 4C, when the guide arm 16 is returned to the original horizontal state from this state, the roll sheet 2 moves between the rails 53 and 53, and the same arrow as the inclination of the rail 53 indicates. Advance along the direction.

Next, as shown in FIG. 5A, when the roll sheet 2 moves forward to the lower ends of the rails 53, 53, as shown in FIG. The parts 4 and 4 come into contact.
Here, the rotating plates 31 and 31 are provided at both ends of the support link 30. When one rotating plate 31 rotates, the other rotating plate 31 rotates at the same time. Only does not rotate. Accordingly, when the stepped portions 4 and 4 move forward on the rails 53 and 53, a speed difference is caused between the left and right sides. If it does not contact 3, the rotating plates 31, 31 do not rotate, so that the roll sheet 2 is not moved after the tilt prevention mechanism 29.

Next, as shown in FIG. 6 (a), when the roll sheet 2 that is in contact with the rotating plates 31 and 31 and whose inclination is corrected moves in the direction indicated by the arrow A (roll sheet 2c), the steps 4 and 4 are formed. After coming into contact with the guide rails 37, 37 of the clogging prevention mechanism 35, it is lowered from the guide rail 36 (roll sheet 2d). And when the step parts 4 and 4 contact | abut to the inclined surfaces 38 and 38, it will move on the rail 54 from the direction which the arrow B shows (roll sheet 2e).
This is because, as shown in FIG. 6B, the guide rail 36 is not provided between the conventional rails 53 and 54, and only the guide rail 37 without the inclined surface 38 is provided. After the roll sheet 2 advances from the rail 53 in the direction indicated by the arrow C (roll sheet 2d ′), the roll sheet 2 descends in the direction indicated by the arrow D, and the previously stored roll sheet 2 is on the rail 54 (roll Sheet 2 f ′) and fit between the guide rail 37 and the rail 54 (roll sheet 2 e ′), and when a new roll sheet 2 is further lowered from the rear, the roll sheet 2 is interposed between the rail 53 and the guide rail 37. This is because it gets caught and prevents the forward movement.

Thereafter, as shown in FIG. 9, also when moving from the rail 54 to the rail 60, after the stepped portions 4, 4 abut against the guide rails 56, 56 (roll sheet 2 h), between the guide rails 55, 56. , The stepped portions 4 and 4 abut on the inclined surfaces 57 and 57 (not shown) and move on the rail 60.
Further, when moving from the rail 60 to the rail 61 after that, after the stepped portions 4 and 4 are brought into contact with the guide rails 63 and 63, the stepped portions 4 and 4 are lowered between the guide rails 62 and 63. It moves on the rail 61 in contact with inclined surfaces 64, 64 (not shown).

Then, as shown in FIG. 7A, when the roll sheet 2 moves forward on the rails 61 and 61 (roll sheet 2n), the step portions 4 and 4 are locked to the fishhook-like sheet stoppers 41 and 41, and are taken out. The forward movement of the roll sheet 2 is regulated by the mechanism 40 (roll sheet 2o).
Thereafter, when the sheet material 6 is newly wound and the roll sheets 2, 2... Are sequentially advanced, as shown in FIG.

Next, a procedure for taking out the roll sheet 2 from the roll sheets 2, 2... Stored in the sea track 1 and laying the sheet material 6 from the roll sheet 2 on the floor will be described.
When the roll sheet 2, 2... Is stored in the sea track 1 and the handle 43 is rotated in the clockwise direction indicated by the arrow, as shown in FIG. 41 rotates, and as shown in FIG. 7B, the roll sheet 2 is unlocked and moves forward in the direction indicated by the arrow. At this time, as shown in FIG. 7C, the rotation center portion of the sheet stopper 41 abuts on the succeeding roll sheet 2 and the forward movement is restricted. Then, after the roll sheet 2 has passed through the take-out mechanism 40, when the handle 43 is returned to the original position indicated by the arrow, the subsequent roll sheet 2 moves forward and is locked by the sheet stopper 41 and stopped.

  Next, as shown to Fig.10 (a), the step parts 4 and 4 of the roll sheet 2 which passed the stopper mechanism 40 are mounted between the left and right bearings 22 and 23 (roll sheet 2p). Then, as shown in FIG. 10B, a part of the wound sheet material 6 is pulled out to the outside of the sea track 1 and laid on the floor surface. After the laying of the sheet material 6 is completed, the core material 3 is removed, the sea track 1 is moved to a predetermined position, and then the same procedure is repeated, so that the sheet materials 6, 6. Will be laid.

  The sea track 1 configured as described above is disposed at the starting end of the storage passage, and the winding material 8 that forms the roll sheet 2 by winding the sheet material 6 around the core material 3 and the sheet material 6 are wound.

In addition, the sheet material 6 can be easily laid.

  In addition, the misalignment prevention mechanism 15 is arranged such that the height of the guide arm 16 formed in the inverted H shape is different on the left and right sides, and the sheet material 6 is stretched over the guide arm 16 to incline the sheet material 6. After the addition, the inclination of the sheet material 6 is corrected by the support plate 12 with which the end portion of the sheet material 6 abuts on the inclined downward side, thereby preventing the occurrence of positional deviation.

  Further, a pair of rotating plates 31, 31 that rotate in the traveling direction of the roll sheet 2 are connected by a support link 30, and the pair of rotating plates 31, 31 rotate in synchronization after both ends of the core members 3, 3 come into contact. By doing so, it is possible to accurately advance the roll sheet 2.

  Further, the clogging prevention mechanism 35 has guide rails 36 and 37 arranged between the upper and lower rails 53 and 54 on the inner side and the outer side in the vertical direction of the portion where the roll sheet 2 descends, and the lower end of the outer guide rail 37. Is provided with an inclined surface 38 inclined on the lower rail 54 side, and the step portion 4 contacts the inclined surface 38 and advances toward the lower rail 54 side, whereby the roll sheet 2 is accurately advanced. Is possible.

  In addition, the take-out mechanism 40 is controlled to advance by the core member 3 being locked to a fishhook-like sheet stopper 41 provided in the forward direction of the roll sheet 2, and by the rotation operation of the sheet stopper 41 by the handle 43. By releasing the restriction, the stored roll sheets 2, 2... Can be sent out one by one.
