Description

  The present invention relates to an apparatus and a manufacturing method for a grid-like core material, and further relates to a flash panel using the grid-like core material manufactured by this manufacturing method.

  In recent years, so-called flash panels are widely used as building panel materials used for building interior materials, furniture materials, etc., in which a core material is arranged in a rectangular frame and face materials are attached to the front and back surfaces. .

  Conventionally, as a core material of such a flash panel, a cardboard material such as a honeycomb shape or a foaming agent is used.

  However, the corrugated cardboard material and the foaming agent have poor rigidity, and there is a problem that the strength of the flash panel cannot be sufficiently increased.

  For this reason, for example, as disclosed in Patent Document 1, a combination of vertical bars and horizontal bars in a lattice shape is considered as a core material.

  However, in order to combine the vertical beam and the horizontal beam in a lattice shape, there is a problem that notches are formed in each of them, and manpower is required, and the work is complicated and troublesome.

As shown in FIG. 1, the control device 6 includes an input unit 71 and a display unit 72, and controls driving of the various motors based on an input signal from the input unit 71, a detection signal from the sensor, and the like. Thus, a lattice-like core material is formed as described later.

(2. Operation)
Next, the operation of the lattice-shaped core material manufacturing apparatus configured as described above will be described with reference to the flowcharts of FIGS.

  In this manufacturing apparatus, the length of the vertical beam 10 and the horizontal beam 51 and the position of the notch formed in each beam are determined in advance by input values at the input unit 71 and the like. Then, as shown in FIG. 13, based on the start operation of the start button or the like (step S1), the vertical rail supply process (step S2) and the horizontal rail supply process (step S3) are performed in parallel as follows. Run. Then, the horizontal beam 51 is assembled to the vertical beam 10 (step S4). Thereafter, after the vertical beam is conveyed in the longitudinal direction by a predetermined pitch (step S5), if the core material is not completed (step S6: NO), the process returns to the step S3 to set the horizontal beam supply process and the horizontal beam 51. Repeat the process. And if a core material is completed (step S6: YES), a series of processing will be completed and a completed core material will be carried out (step S7). By performing these series of processes continuously, a plurality of core materials are continuously formed.

(2-1. Vertical rail supply processing)
In the vertical beam supply process, as shown in the flowcharts of FIGS. 14 and 15 and the time chart of FIG. 17, first, the vertical beam pusher 12 is driven, and the vertical beam 10 positioned at the bottom of the vertical beam magazine 11 is driven. Are supplied to the first guide member 13 in order (step S11). The first guide member 13 closes the first shutter 18 and waits until a predetermined number of vertical bars 10 are supplied (step S12). Further, the second guide member 14 is moved along the first support block 19 and positioned so as to be continuous with the first guide member 13 (step S13). When the supply of the predetermined number of vertical bars 10 to the first guide member 13 is completed (step S14: YES), the first shutter 18 of the first guide member 13 is opened and the vertical bars 10 held by the first guide member 13 are opened. Is transferred to the second guide member 14 (step S15). And the 2nd guide member 14 is moved to the upper direction of each conveyance rail part 15, and the vertical rail 10 to hold | maintain is supplied one by one (step S16). Here, the second shutter unit 24 is closed or the next vertical beam 10 is pressed by the second shutter unit 24 and the first shutter unit 23 is opened, so that only the vertical beam 10 located at the head is transferred to the transport rail unit 15. And supply. Then, the first shutter 18 is closed and the second shutter 22 is opened, so that the next vertical rail 10 can be supplied. Thereafter, similarly, the second guide member 14 is moved to the upper side of the next transport rail portion 15 and the vertical rails 10 are supplied one by one.

  When the supply of the vertical beam 10 to each conveyance rail portion 15 is completed (step S17), the movable roller 29 is moved closer to the fixed roller 28 and the vertical beam 10 is sandwiched between the rollers 28 and 29 (step S18). ). Then, the fixed roller 28 is driven to rotate, and the vertical rail 10 is conveyed in the longitudinal direction toward the assembly member 45 (step S19). At this time, the clamping member 38 is previously positioned at the contact position (indicated by a two-dot chain line in FIG. 8), and the clamping piece 40 is closed. Thereby, the front end surface of the vertical rail 10 conveyed from the conveyance rail portion 15 comes into contact with the stopper surface 41 formed by the both clamping pieces 40.

  If the sensor detects that the front end surface of the vertical beam 10 abuts against the stopper surface 41 and is positioned at the reference position (step S20), the driving of the fixed roller 28 is stopped (step S21). The movable roller 29 is separated (step S22). Thereby, conveyance of the vertical rail 10 is interrupted. Accordingly, the longitudinal beam notch forming member 9 is driven to close the rotating piece 42, thereby forming a notch in the short direction in the longitudinal beam 10 (step S23).

  If the longitudinal rail 10 is formed with a short cut, the clamping piece 40 is opened, the vertical beam transporting member 8 is moved to the conveyance start position (shown by a solid line in FIG. 8), and the clamping piece 40 is again formed. The vertical rail 10 is gripped by closing (step S24). After the vertical beam 10 is conveyed by a predetermined pitch by the vertical beam transfer member 8 and positioned at the notch forming position (step S25), the vertical beam notch forming member 9 is driven again to close the rotating piece 42. A notch in the short direction is formed in the vertical beam 10 (step S26). At this time, the previously formed notch is positioned at the assembly position.

  In the same manner, the vertical beam 10 is moved by a predetermined pitch by the vertical beam transfer member 8 to sequentially form notches in the short direction.

(2-2. Horizontal rail supply processing)
On the other hand, in the horizontal beam supply process, as shown in the flowchart of FIG. 16 and the time chart of FIG. 18, the belt conveyor 53 is driven, and the horizontal beam 51 positioned at the bottom of the horizontal beam magazine 52 is changed to the horizontal beam standby unit 54. (Step S31). In the horizontal beam standby unit 54, when the conveyed horizontal beam 51 enters between the upper and lower flat plates 55 and is detected by a sensor (not shown) (step S32), the air cylinder 57 is driven to move the horizontal beam 51 to the horizontal beam 51. It pushes out to the transfer part 47 (step S33).

  In the horizontal beam transfer section 47, the pushed horizontal beam 51 is held in the holding recess 60 formed at the tip of the support arm 59 located at the horizontal beam holding position. Since the ball of the ball plunger 61 protrudes from the holding recess 60 as described above, the holding state of the horizontal rail 51 is stable.

  In FIG. 12, the horizontal beam 51 held in the holding recess 60 is moved to the horizontal beam cutting position by rotating the support disc 58 by 90 degrees clockwise about the support shaft 58a (step S34). At the horizontal beam cutting position, one end surface of the horizontal beam 51 is pressed by the horizontal beam pusher 64 and positioned at a predetermined position (step S35). At this time, the cutter 63 is positioned at the separation position, and if the crosspiece 51 is positioned at the predetermined position, it is cut to have a constant dimension (step S36).

  If the horizontal beam 51 is cut by the cutter 63 and has a certain size, the horizontal beam transfer part 47 is further rotated 90 degrees in the clockwise direction to move to the notch formation position (step S37). At the notch forming position, the motor 66b is driven and the position of the horizontal beam with respect to the horizontal beam notch forming part 49 is adjusted by the positioning pusher 66c (step S38). That is, when the horizontal beam 51 is assembled according to the number of the vertical beams 10 transferred to the vertical beam assembly position, the notches are formed so that the protruding dimensions of the horizontal beam from the vertical beam 10 located on both sides thereof are equal. Adjust the position to form. Then, the rotary piece 65 is opened to advance toward the horizontal rail 51, and the rotary piece 65 is closed, thereby forming a notch in the lateral direction in the horizontal rail 51 (step S39).

  If a plurality of cutouts are formed in the horizontal crosspiece 51, the horizontal crosspiece transfer portion 47 is further moved 90 ° clockwise to move to the horizontal crosspiece assembly position (step S40). This horizontal beam assembly position coincides with the position where the vertical beam 10 is conveyed by one pitch from the vertical beam notch position. Therefore, by raising the pushing plate 67 of the pushing portion 50, the notch of the horizontal beam 51 can be engaged with the notch of the vertical beam 10, and the horizontal beam 51 can be assembled to the vertical beam 10. .

  In this way, a notch is formed in the vertical beam 10 and conveyed by a predetermined pitch in the longitudinal direction by the vertical beam transfer member 8, while a notch is formed in the horizontal beam 51 at a position corresponding to each row of the vertical beam 10. It is rotated by the crosspiece transport unit 47 so that the cutout of the horizontal crosspiece 51 matches the cutout of the vertical crosspiece 10. The vertical beam transfer member 8 and the horizontal beam transfer unit 47 are both positioned with respect to the lower support base 4 of the apparatus main body 1. Therefore, the notch of the horizontal beam 51 can be accurately aligned and engaged with the notch of the vertical beam 10.

  Therefore, as described above, the pushing plate 67 is raised by driving the air cylinder 67a, and the horizontal beam 51 is assembled to the vertical beam 10 (step S4).

  Similarly, the vertical beam 10 is conveyed by a predetermined pitch (step S5), and the horizontal beam 51 is assembled to complete the core material. In each step of completing the core material in this way, there are only a cut end generated when each crosspiece is cut into a predetermined size and a cut piece generated when the cutout is formed. In other words, it is possible to minimize the generated waste material. Whether or not the core material is completed may be determined based on whether or not the number of horizontal rails 51 assembled to the vertical rail 10 has reached the number of notches registered in advance.

  The completed core material reaches the discharge member 68 and is sandwiched between the upper roller 70 and the lower roller 69 moved upward, and the lower roller 69 is rotationally driven to rotate the apparatus main body 1. (Step S7).

  The discharged core material moves to the next step, and if a decorative board or the like is attached to the front and back surfaces by an assembly device (not shown), it becomes a flash panel. The completed flash panel can be used as a shelf, a door, a wall, or the like.

(3. Other embodiments)
In addition, this invention is not limited to the structure described in the said embodiment, A various change is possible within the range described in the claim.

  For example, in the above-described embodiment, the notch is formed in the lower edge of the vertical beam 10 and the horizontal beam 51 is assembled from the lower side. However, the vertical positional relationship can be reversed.

  Moreover, in the said embodiment, although the arrangement | positioning space | interval of each vertical cross 10 was made into the specific value, this space | interval can be changed freely. In this case, the position of the notch formed in the horizontal rail 51 may be changed.
