  The size in the width direction of the cushioning material produced by the conventional cushioning material forming apparatus of Patent Document 1 can be produced with a desired length, but the length is determined by the length of the corrugated paper that has been input and is produced and discharged. The For this reason, when using it by packing etc., it cut | disconnects and uses it separately to length required. Further, when cutting to a desired length, it is necessary to separately provide a cutting part, which makes the entire apparatus longer and more complicated. Furthermore, in the shock absorber manufacturing apparatus of Patent Document 2, a perforation is formed in the cutting part and can be easily separated, but the perforation needs to be separately formed in advance on the paper material to be supplied. In addition, there is a need to separately manufacture a paper material in a roll shape. Furthermore, it is inconvenient when using corrugated paper such as scrap.

  Therefore, the present invention can use a plate-like material such as corrugated paper, and can easily produce a cushioning material used for packaging etc. in one process, and the cushioning material is manufactured by cutting into a certain length. An object is to provide a shock absorber manufacturing apparatus.

  In order to solve the above problems, an upper roller cutter and a lower roller cutter having a horizontal rotation axis provided in parallel vertically are arranged, and a plate-like material passed between the upper roller cutter and the lower roller cutter In the shock absorber manufacturing apparatus provided with the notch forming part for forming the slit and the downstream guide part of the plate-like material provided downstream of the notch forming part, the notch forming part is provided for the supplied plate-like material. Proposed shock absorber manufacturing device characterized by intermittently forming slits parallel to the flow direction and cutting and separating the plate material at regular intervals in the flow direction in a direction perpendicular to the flow direction. is there.

  Moreover, in the cushioning material manufacturing apparatus described in the column 0005, the upper roller cutter and the lower roller cutter of the incision forming part are each configured by overlapping disk-shaped cutters at regular intervals in the axial direction, The upper roller cutter and the lower roller cutter are arranged so as to overlap each other so that the outer circumference of the upper roller cutter and the lower roller cutter are slightly engaged with each other in a side view. A notch is provided as appropriate, and the concave notch is provided with a concave notch having a rounded corner formed by the outer periphery of the cutter of the concave notch, and one of the corners provided at an acute angle. There is a concave notch formed at the corner, and the supply plate-like material is orthogonal to the flow direction by the action of the concave notch having the corner provided at the acute angle. In which it proposed a buffer material manufacturing apparatus characterized by cutting separation direction.

  According to the invention of claim 1, the slits parallel to the flow direction of the plate-like material supplied in the notch forming portion are intermittently formed, and the plates are arranged at regular intervals in the flow direction in a direction perpendicular to the flow direction. In order to cut and separate the material, the manufactured cushioning material is manufactured with a certain length. For this reason, it is possible to easily adjust the amount of use by using a necessary amount of cushioning material cut and separated at the time of packing. In addition, since the corrugated cardboard such as waste material can be used as the plate-like material to be supplied, the manufacturing cost of the buffer material can be suppressed, and a buffer material manufacturing apparatus with high versatility of the supply material can be provided.

  According to the second aspect of the present invention, the supply plate-like material is perpendicular to the flow direction by the action of the concave notch having a corner provided with an acute angle between the concave notch and the outer periphery of the cutter. The slit forming portion configured to cut and separate into two can simultaneously perform slit formation and lateral cutting with a simple structure. Therefore, it is possible to provide a shock absorber manufacturing apparatus that is easy to check and adjust and that is configured compactly.

  An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view of a shock absorber manufacturing apparatus showing an embodiment of the present invention, FIG. 2 is a side sectional view of a main part of the shock absorber manufacturing apparatus into which a plate-like material is charged, and FIG. 3 is an upper roller cutter and a lower roller cutter. FIG. 4 is a plan view of the plate-like material after passing through the notch forming portion, and FIG. 5 is a timing chart of the concave cut-out portion of the disc-shaped cutter and the plate-like material forming portion. It is explanatory drawing which showed these contrasts.

  The shock absorber manufacturing apparatus 1 includes an upstream guide portion 12 on the side where a plate-like material W such as corrugated cardboard to be molded is introduced, a forced feeding portion 5 that forcibly feeds the introduced plate-like material W, and a downstream side thereof. The notch forming part 2 for forming the slit 60 and the separating part 61 in the plate-like material W and the downstream guide part 13 for forming and discharging the ridges on the plate-like material W are sequentially arranged in the horizontal direction, and the upstream guide If the height of the part 12 is set to a height at which the operator can easily put the plate-like material W, the burden on the operator can be reduced. In addition, a drive motor 3 for driving the apparatus is installed below these parts.

  The forced infeed section 5 has two forced infeed rollers 51 arranged in parallel in the vertical direction, sandwiching the loaded plate-like material W between the upper and lower forced infeed rollers 51, and feeding the plate-like material to the downstream side of the making side. They are provided so as to rotate in the reverse direction in the feeding direction. The forced feeding roller 51 is provided with protrusions radially on the outer periphery, so that the plate-like material W can be securely held and fed.

  An inlet cover 11 is provided on the upstream guide part 12 side of the forced feeding part 5 to prevent the operator from being caught, and the gap between the lower surface of the upstream guide part 12 and the inlet cover 11 is a plate-like material. It is provided as close as W can pass.

  The notch forming part 2 is provided with an upper roller cutter 21 and a lower roller cutter 22 that are two roller cutters as shown in FIG. The upper roller cutter 21 and the lower roller cutter 22 are attached to the upper rotary shaft 23 and the lower rotary shaft 24, respectively, and are driven in reverse rotation to each other in the direction of sandwiching the upstream plate-like material W up and down and feeding it to the downstream side. .

  Each of the upper roller cutter 21 and the lower roller cutter 22 has a large number of disk-shaped disk-shaped cutters 25 each having a thickness of several millimeters stacked on the upper rotary shaft 23 and the lower rotary shaft 24 with a gap of several mm. It is attached. The inter-axis dimension of the rotating shaft is set so that the outer circumference of the upper roller cutter 21 and the lower roller cutter 22 overlaps with each other in a slightly meshed state in a side view so as to enter the gap between the disk cutters 25. .

  The disc-like cutter 25 is partially provided with a concave cutout portion 251 on the outer peripheral portion, and by setting the phase of these concave cutout portions 251 of the adjacent disc-like cutters 25, a plate-like shape is obtained. The slit 60 can be formed in the material W, or the portion without the slit 60 can be continuously formed. For example, when the disk-shaped cutter 25 of the lower roller cutter 22 is located between the disk-shaped cutters 25 on the upper roller cutter 21 side, and neither of the overlapping disk-shaped cutters 25 has the concave notch 251. The disk-shaped cutter 25 on the upper roller cutter 21 side of the upper roller cutter 21 in the overlapping portion is formed on the plate-shaped material W into which the slits 60 are inserted in parallel with an interval corresponding to the thickness of the disk-shaped cutter 25 of the lower roller cutter 22. If the concave notch 251 is formed in the slit 60, the slit 60 is not formed. Thus, the pattern of the slit 60 to be formed can be adjusted by adjusting the phase timing of the concave notch 251 in the overlapping portion of the upper roller cutter 21 and the lower roller cutter 22.

  The concave notch 251 includes a concave notch formed by an R-shaped corner 252 having a smooth corner formed by the outer periphery of the disk-shaped cutter 25 of the concave notch 251 and one of the corners. There is a concave cutout portion formed by an acute angle portion 253 provided at an acute angle, and the overlapping portion of the upper roller cutter 21 and the lower roller cutter 22 is located at a portion where the concave cutout portion 251 is not located on both sides. When the acute angle corner 253 of the concave notch 251 is positioned on the disk-shaped cutter 25, the plate-like material W is cut by the acute angle corner 253 in a direction orthogonal to the flow direction by the cutter width. This action part is installed in one of the adjacent slits, and the position is slightly shifted in the direction of the flow and installed in the adjacent slit part, so that the plate is zigzag in a direction perpendicular to the direction of the flow. The shaped material W is cut.

  The plate-like material W that has passed through the cut forming portion 2 is sent to the downstream guide portion 13 further downstream. In the downstream side guide part 13, it inserts and sends between the table of a horizontal surface, and the downstream side press board 42 which rotates to the upper direction on the upper side by using the base side of the downstream side guide part 13 as a rotation fulcrum. A weight 43 is attached to the upper surface of the downstream pressure plate 42, and the other end pivots downward about the rotation fulcrum on the base side and presses with the weight of the weight 43. For this reason, resistance acts in the feeding direction on the plate-like material W that is sent, and the plate-like material W is softened by a large number of slits 60 formed by the notch forming portion 2, so that it is deformed or uneven in a corrugated plate shape. It is deformed into a shape and provides a cushion function as a cushioning material. The deformed plate-like material W is sequentially discharged out of the apparatus while resisting resistance in the feeding direction.

  A drive motor 3 that drives the shock absorber manufacturing device 27 is installed below the notch forming portion 2, and a lower roller cutter 22 is attached by a roller chain 33 that is spanned from a drive sprocket 32 that is fixed to the output shaft. The power is transmitted to the lower roller sprocket 27 fixed to the end portion of the lower rotary shaft 24 to be driven to rotate.

  A cutter interlocking gear 35 for interlocking the rotations of the upper and lower cutters 21 and 22 is provided and meshed with the end of the lower rotating shaft 24 and the end of the upper rotating shaft 23. For this reason, the positional relationship of the concave notch 251 of the disk-shaped cutter 25 is maintained constant. Further, an upper roller sprocket 26 is fixed to the end of the upper rotary shaft 23, and the feed roller sprocket 53 and the roller chain 34 of the forced feed portion 5 are wound around this to transmit power to the forced feed portion 5 and drive it. is doing. The feed roller sprocket 53 is fixed to the end of the feed roller rotating shaft 52 to which the forced feed roller 51 is attached. In addition, a feed roller interlocking gear 36 is provided and meshed with the end portion of the feed roller rotating shaft 52 so that the upper and lower rollers 51 and 51 rotate in conjunction with each other.

  The process in which the slit 60 and the separation part 61 are formed in the plate-like material W in FIG. 5 will be described. In A part, it cut | disconnects by the acute angle corner | angular part 253 of the lower roller cutter 22 in the direction orthogonal to a flow. Furthermore, it rotates and is cut | disconnected by the acute angle corner | angular part 253 of the upper roller cutter 21 in B part. Moreover, when forming the continuous slit 60 in the flow direction as in the C portion, the slits 251 of the upper and lower cutters 21 and 22 are formed when the portions that do not have each other overlap. Furthermore, at the D position where the slit 60 is not formed, the concave cutout portion 251 having only the rounded corner portion 252 of one of the upper and lower cutters is positioned so that the slit 60 is not formed at the passage portion.

  The E portion is formed by a cutter provided adjacent to the cutter that forms the A portion of the lower roller cutter 22, and the slit of the F portion, the non-slit portion of the G portion, and the slit forming portion of the H portion are sequentially cut into concave shapes. They are formed by the combined arrangement of the notch portions 251.

  In order to manufacture the buffer material with the buffer material manufacturing apparatus 1 having the above-described configuration, the apparatus is activated by the activation switch 16 provided above the apparatus, and the plate-like material W to be molded is placed on the table of the upstream guide unit 12, It is inserted into the slot formed by the gap between the front slot cover 11 and the table 14. When the inserted plate-like material W reaches the forcible feeding portion 5, it is sandwiched between the upper and lower forcible feeding rollers 51, 51 and sent to the downstream side. On the downstream side of the forced feeding portion 5, there is a notch forming portion 2, which is inserted so that the plate-like material W is sandwiched between the upper roller cutter 21 and the lower roller cutter 22 positioned above and below, and the slit 60. Are formed, and separation parts 61 are formed at regular intervals in the flow direction. When the downstream guide portion 13 is further fed, it is inserted between the table fixed on the horizontal plane and the downstream press plate 42 that rotates in the vertical direction above it, and the downstream press on which the weight of the weight 43 acts. The plate-like material W is pressed by the plate 42, and a sandwiching resistance that prevents the flow acts to reduce the flow speed. On the other hand, since the upstream sending side feeds at a constant speed, a force acts on the plate-like material W in the horizontal direction, which is the flow direction, and buckling continuously occurs. Is formed and discharged as a cushioning material. Since the discharged cushioning material is cut and separated to a certain length, there is no need to cut it again to the required length when using it for packing, etc. If the fixed length is not enough, use the required number Good. An emergency stop switch 15 and a reverse rotation switch 17 are provided on the upper surface of the apparatus, and can be stopped and reversed to be removed when a foreign object is caught or the drive resistance increases.
