Description

  The present invention relates to a side block storage device, and more specifically, for each of storage chambers configured in multiple stages, a side block for setup change and a traction / guide means for towing / guidance of an existing side block can be stored. The stored side change-use side block can be paid out, and the existing side block can be pulled and guided by the pulling and guiding means to be accommodated in the multi-stage storage chamber. The present invention relates to a side block storage device.

  When continuously producing rigid polyurethane foam panels (hereinafter sometimes referred to as “panels”) that are frequently used for heat insulation boards, etc., generally, a rigid polyurethane foam stock solution is supplied from the mixing head onto the bottom material sent at a predetermined speed. The composition (hereinafter, simply referred to as “foaming stock solution”) is discharged, and the same is covered with a top material that is fed out at a predetermined speed, while maintaining the temperature at a predetermined temperature and adjusting the position to a predetermined height. It passes between the upper and lower belt conveyors (double conveyor) made (for example, patent document 1).

  Meanwhile, the foaming stock solution discharged onto the lower surface material begins to foam while being sandwiched between the upper surface material, and is molded into a predetermined shape and cured so as to have a predetermined thickness so as to have a predetermined thickness.

  At this time, since the discharged foaming stock solution expands even toward the side surface, side blocks are arranged on both side surfaces of the double conveyor to prevent the foaming stock solution from expanding and overhanging beyond a predetermined width. This side block has a structure in which a number of hard resin blocks are connected to a chain, and the height of the hard resin blocks corresponds to the thickness of the rigid polyurethane foam panel.

  And when manufacturing the panel of different thickness, another side block provided with the block made from hard resin corresponding to the height is prepared, and it replaces (stage change).

  Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a plan view showing an arrangement state of the side block storage device according to the present embodiment in the panel production line, FIG. 2 is a diagram showing the start of the side block changeover, and FIG. FIG. 3B is a right side view, FIG. 3 is a diagram showing a state where the side block is completely changed, FIG. 3A is a front view, and FIG. 3B is a right side view.

  In the panel continuous production line shown in FIG. 1, as described above, the side blocks SB are arranged on both sides of the double conveyor DC (represented as an occupied place in order to avoid complication), and the positions of the upper and lower surface members in the horizontal direction are arranged. At the same time, the foamed foam is prevented from projecting in the panel width direction. As described above, the side block SB is configured by connecting a number of hard resin blocks to the chain, and the total length of the side block SB is 50 m, and the pair of sprocket wheels 7 are arranged along the panel production line. It is wound in a loop shape.

  Side block storage devices 1 are arranged outside both side blocks SB adjacent to both side blocks SB, respectively. The side block storage device 1 is movable on the rail 2 (only one is shown). Usually, the side block storage device 1 is arranged on the wall W side and it is necessary to change the setup. Sometimes, it can be moved on the rail 2 to be close to the side block SB.

  As shown in FIGS. 2 and 3, the side block storage device 1 is configured with two storage chambers, and when changing to a side block having a different thickness, an empty rack for storing is set in the lower stage. Set the rack for the new side block to be used on the upper level. And when manufacturing the panel from which thickness differs, the side block accommodated in the upper stage is pulled out, and it replaces with the side block in use.

  The side block SB accommodated in the upper storage chamber 1a of the side block storage device 1 is arranged at one place in the longitudinal direction as shown in FIG. 1 in plan view, and is mounted on the electric motor 8 (attached to one rotary drive shaft). 2), and the winding state is plural in the vertical direction in each storage chamber of the side block storage device 1 as shown in FIGS. 2 (a) and 2 (b). The wheels 6 arranged in stages are sequentially wound and stored in a spiral shape (in FIG. 2, a side block SB to be replaced is stored on the upper storage chamber 1a side). That is, the plurality of wheels 6 arranged at two locations in the longitudinal direction are arranged with their height positions somewhat shifted from each other, and the side block SB wound around these wheels 6 is folded back to the wheel 6. Every time the direction is changed, the height changes. Here, the wheel 6 provided with the electric motor 8 corresponds to a rotation driving means. The wheel 6 also has a sprocket structure and is equipped with a clutch mechanism (air clutch or the like). When a load outside the design is applied when the side block SB is wound up, a chain or a device connected with the chain is used. Can be prevented from being damaged.

  On the side of the lower storage chamber 1b of the side block storage device 1, a guide chain 3 that pulls the side block SB is spirally wound between the wheels 6 from the upper stage to the lower stage and stored. The lowermost stage of the guide chain 3 is connected to the uppermost guide chain and arranged in a rope shape as a whole. Then, one end side of the drawing chain 4 having a length of about 500 mm is connected to the uppermost step portion of the guide chain 3, and the other end side of the drawing chain 4 is connected to the tip of the side block SB. The wheel 6 is rotated by driving 8, and the side block SB is pulled toward the lower storage chamber 1b and stored in the lower storage chamber 1b of the side block storage device 1.

Then, the drive motor (not shown) of the sprocket wheel 7 of the side block SB and the drive motor 8 of the wheel 6 in the side block storage device 1 are simultaneously rotationally driven at a predetermined speed (for example, about 4 to 8 m / min), The side block SB is pulled into and stored in the side block storage device 1.

  On the other hand, the right side block SB separated at point A is temporarily pulled to move to point B as the left side block SB moves, and temporarily stops the operation of the drive motor of the sprocket wheel 7. Then, the front end side of the new side block SB stored in the upper storage chamber 1a of the side block storage device 1 is pulled out somewhat by driving the drive motor of the wheel 6, and the rear end side of the existing side block SB and Connecting. The new side block SB corresponds to a panel having a different thickness, and is mounted with a hard resin block having a height different from that of the existing side block.

  Thereafter, the drive motor of the sprocket wheel 7 of the side block SB is restarted, and the drive motor of the wheel 6 in the upper storage chamber 1a of the side block storage device 1 is simultaneously rotated at a predetermined speed, so that the side block SB is A new side block SB is pulled out from the upper storage chamber 1a of the block storage device 1 and pulled to the point C. At this time, most of the existing side blocks are spirally stored in the lower storage chamber 1 b of the side block storage device 1.

  At point C, the connection between the existing side block SB and the new side block SB is disconnected, and the existing side block SB is continuously pulled and guided by the guide chain 3 to the lower storage chamber 1b of the side block storage device 1. The stored new side block SB is pushed out to the point B by the drive motor of the wheel 6 in the upper storage chamber 1a of the side block storage device 1. But you may move the front-end | tip of the new side block SB in this case using transfer apparatuses, such as a hoist arrange | positioned in a factory. Then, at the point B, the front end of the new side block SB is connected to the rear end of the new side block SB from which the connection of the guide chain 3 is released. This connection is made by connecting the chain portions of the two. For the other side block, the setup is changed in the same manner.

  In this way, the changeover start state shown in FIGS. 2 (a) and 2 (b) is changed to the changeover completion state shown in FIGS. 3 (a) and 3 (b). Requires 2 to 3 people (1/2 to 1/3 compared to the prior art), and most of the work is automated and easy, and the operator needs to touch the blocks that make up the side blocks. Since there is no work safety, it is possible to perform setup change efficiently while smoothly handling side blocks that are difficult to handle with long objects (the setup change time is about 0.5 hours, which is less than 1/3 of the conventional one) ) In addition, the side blocks of the long object can be easily taken out, and can be spirally stored in a three-dimensional manner. Therefore, the payout is easy, and the occupation space can be collected in a compact manner.

  Further, as shown in FIGS. 2 and 3, the side block storage device 1 described above is configured as a rack having a specific shape. The entire block is enclosed by a sheet or the like, and warm air is circulated inside the block. It can be easily heated, and when changing the setup, a new side block can be placed in the double conveyor line in a heated state.
