  In general, this type of cutting apparatus, for example, as shown in FIGS. 19 to 21, with respect to a mountain-shaped lower knife 52 in which a knife bar 53 slides back and forth on a lower knife plate 51 and is arranged in parallel on the lower knife plate 51. A configuration in which a plurality of mountain-shaped knives 54 arranged in parallel on the knife bar 53 are slid and reciprocated from the overlapping positions that pass each other to the overlapping positions that coincide with each other to cut the object to be cut between each lower knife 52 and the knife 54. is there.

  The knife bar 53 for reciprocating sliding is configured to convert the rotational motion to a left and right sliding motion via a crank mechanism or the like and reciprocate on the lower knife plate 51. A slide guide member 61 is provided as a slide guide mechanism for guiding reciprocation.

  Specifically, the slide guide member 61 is overlapped between the guide plates 58 and 59, a rear guide plate 58 that is fastened and fixed to the lower knife plate 51, a front guide plate 59 that is spaced apart from the rear guide plate 58, and the guide plates 58 and 59. The knife clip 60 comprises a gap between the rear guide plate 58 and the front guide plate 59 as a guide gap 62, and the knife bar 53 is slidably fitted into the guide gap 62. The front guide plate 59 is arranged above the knife 54 as a blade pressing bar, and the rear guide plate 58 is threaded through the lower knife plate 51 with two fastening bolts 66. The slide guide member 61 is fixed on the lower knife plate 51 by wearing and tightening and fixing. To have.

  On the lower knife plate 51, a spacer 69 is superposed on the lower guide plate 68 in a stepwise manner to support the knife 54 base on the lower surface of the knife bar 53 and to have the same height as the lower knife 52 base on the lower knife plate 51. The front guide plate 59 is formed between the spacer 69 and the rear guide plate 58 that form a surface 67 and further between the rear guide plate 58 and the knife clip 60 or between the spacer 69 and the rear guide plate 58 that form the step surface 67 on the lower guide plate 68.

Thus, the structure is fastened and fixed via the fastening bolt 66.

  By the way, because of the difference in the width of the knife bar 53 or the slide reciprocation by the crank mechanism of the knife bar 53, the knife bar 53 and the rear guide plate that reciprocate between the guide gaps 62 between the rear guide plate 58 and the front guide plate 59 are provided. 58 and the front guide plate 59 may wear each other, and the wear may cause the width of the knife bar 53 and the guide gap 62 to change with time. To cope with this, the rear guide plate 58 can be finely adjusted. The fastening hole 58a of the rear guide plate 58 is a long hole so that the tightening and fixing position of the rear guide plate 58 can be finely adjusted. Therefore, the guide gap 62 can be adjusted in accordance with the wear as described above, and this is excellent in that the backlash of the knife bar 53 can be suppressed, the vibration of the knife 54 can be suppressed, and the sharpness can be maintained. However, as described above, the slide guide member 61 has a large difference in the amount of wear at each provided position, so that it is very troublesome and requires skill because fine adjustment is made while maintaining the overall wear balance.

When fixing on the knife plate 51, the clearance necessary for the knife bar 53 to slide back and forth between the guide gaps 62 between the rear guide plate 58 and the front guide plate 59 is provided. When the rear guide plate 58 is fastened and fixed via the left and right tightening bolts 66, the rear guide plate 58 and the front guide plate 59 are rotated around one tightening bolt 66 as a result of the tightening rotation of the tightening bolt 66. As a result, the rear guide plate 58 is finely adjusted unless it is an expert. It is always troublesome, and when the knife bar 53 is slid back and forth in a state where the rear guide plate 58 and the front guide plate 59 are inclined, the rear guide plate 58 and the front guide plate 59 are unbalanced and wear unevenly (see FIG. 21). Therefore, as described above, not only the knife bar 53 but also the rear guide plate 58 is heavily worn and requires frequent adjustment or replacement. In addition, for example, when the tightening bolt 66 is loosened due to vibration generated during the operation and the tightening force is reduced, the rear guide plate 58 and the front guide plate 59 are rotated to cause uneven contact. This is the cause and the operating load resistance, and because of the above-mentioned uneven contact, the assembly operation balance is poor, which causes uneven wear and a decrease in strength in the slide guide mechanism.

  The present invention solves such a conventional problem, and comprises a parallel movement locking mechanism by concave-convex engagement between the concave strip portion and the convex strip portion at the overlapping portion of the knife clip and the rear guide plate. Therefore, fine adjustment of the guide gap is easy, assembly is extremely easy, wear resistance is excellent, fine adjustment after assembly is also extremely easy, and as a result, assembly is performed as designed, resulting in an extremely balanced assembly operation. In addition, the strength of the slide guide mechanism can be obtained with certainty, and the uneven wear and slide operation load of the rear guide plate, front guide plate, knife bar, etc. of the slide guide member can be improved. The purpose is to provide an innovative clipper-type cutting device that can suppress vibration and increase the durability and durability of sharpness. .

  With respect to the configuration in which it is possible to confirm whether or not the ridge 15 is engaged with any one of the ridges 14, the lateral width of the rear guide plate 8 (the width in the sliding direction of the knife bar 3) is set to the lateral width of the knife clip 10. In contrast, the left and right exposed portions of the rear guide plate 8 where the knife clip 10 does not overlap are provided on the lateral extension line of the ridges 15 so that the memory 17a is provided. Engagement position visualizing means 17 capable of visually recognizing the engagement position of the concave strip portion 14 of the knife clip 10 that engages with the strip portion 15 is provided.

  Specifically, as described above, the ridges 15 provided in the entire lateral width direction of the rear guide plate 8 are extended to the left and right exposed portions of the rear guide plate 8 where the knife clips 10 are not overlapped. It is provided to function as 17a.

  Therefore, by providing the engagement position visualizing means 17, the wear amount of the rear guide plate 8, the front guide plate 9, and the knife bar 3 in each of the slide guide members 11 arranged in parallel on the lower knife plate 1 can be simplified. For example, it is possible to reliably grasp the situation even in a dirty state after the workpiece 5 is cut. As a result, the situation of the rear guide plate 8 in each slide guide member 11 can be determined between the slide guide members 11. If the wear amount of parts on the slide guide member 11 on one side of the lower knife plate 1 is significant, for example, the slide structure member It will also be possible to grasp the situation of the entire cutting device, such as a warning bell that there may be a problem with

  In this embodiment, the memory 17a is constituted by the ridges 15 provided on the rear guide plate 8. However, when the ridges 14 are provided on the rear guide plate 8, the memory 17a is provided with the memory. 17a may be configured, and the rear guide plate 8 may be provided with marks (dots, lines, etc.) for coloring the rear guide plate 8 even if it is not the above-described convex strip portion 15 or concave strip portion 14. In addition, the memory 17a may be provided only in one of the left and right exposed portions of the rear guide plate 8 where the knife clip 10 does not overlap.

  Further, in this embodiment, a lower guide plate 20 having a step surface 19 which supports the knife 4 base on the lower surface of the knife bar 3 and has the same height as the lower knife 2 base between the lower knife plate 1 and the rear guide plate 8. Further, a shim 21 is interposed between the lower guide plate 20 and the rear guide plate 8 on the upper side of the lower guide plate 20 as necessary, and the lower knife plate 1 has the lower guide plate 20, shim 21, The overlapping portion of the rear guide plate 8 and the knife clip 10 is fastened and screwed by the fastening housing 13 through the fastening holes 1a, 20a, 8a, 10a provided in the respective parts, and the slide guide is placed on the lower knife plate 1. The member 11 is fastened and fixed.

  In this embodiment, the length of the front guide plate 9 in the sliding direction of the knife clip 10 of the slide guide member 11 is set to be longer than the length of the knife bar 3 in the sliding direction, and the rear guide plate 8 is also mounted on the front. The guide gap 12 is set to be as long as the guide plate 9, and the guide gap 12 is set to be longer than the lateral width of the knife clip 10.

  Accordingly, the slide guide mechanism 7 is configured with a minimum number of plates, and in particular, the slide guide member 11 is an assembly of the plate, and is assembled and integrated so as to be adjustable. Since it is configured to be fastened and fixed together, it can be assembled and formed with a plate made of a material with high hardness with less wear, and the guide gap 12 with less wear can be formed without increasing the cost.

  Further, by setting the rear guide plate 8 and the front guide plate 9 longer than the knife clip 10 and forming the guide gap 12 longer, the wear can be further suppressed, and the backlash of the knife bar 3 due to this wear is further suppressed. In addition, even if the rear guide plate 8 and the front guide plate 9 are set to be long and the guide gap 12 is formed to be long as described above, the cost is not so high for the assembly by the plate.

  Further, when the slide guide member 11 is fastened and screwed to the lower knife plate 1, the step of supporting the base of the other knife 4 of the adjusting shim 21 and the same height as the base of the lower knife 2 as described above. The lower guide plate 20 having the surface 19 is interposed and tightened and fixed by the fastening housing 13.

  That is, the lower guide plate 20 is not a two-piece structure, but is integrally formed as a single piece having a stepped surface 19, which is interposed as the lower guide plate 20 and the upper slide guide member 11 and the lower knife plate with the fastening housing 13. 1 is tightened and fixed by screwing, and the strength of the slide guide mechanism 7 is further increased. Therefore, the “deflection” in the longitudinal direction due to the dead weight of the knife bar 3 which has affected the durability, which is a problem of the clipper blade, is eliminated, and the knife 4 that is in contact with the front guide plate 9 of the slide guide member 11 or the like. The uneven wear will be improved, and this can suppress the vibration of the knife and increase the sustainability of the sharpness.

  Therefore, it is possible to suppress wear even though the structure is easy to assemble and difficult to increase in cost, and the strength of the slide guide mechanism 7 is increased, thereby preventing the deflection of the entire length of the knife bar 3, thereby preventing the knife bar 3 from sliding. Therefore, the sharpness is excellent and the epoch-making clipper type cutting device is extremely excellent in sustainability.

  The generation of wear and the adjustment of the guide gap 12 in the clipper type cutting apparatus according to the present embodiment having the above-described configuration will be described.

  The slide guide member 11 is fastened and fixed to the lower knife plate 1 (see (a) in FIG. 7). In this state, the knife bar 3 is slid back and forth by the slide reciprocating mechanism 6, and the knife 4 is slid back and forth relative to the lower knife 2. Thus, the workpiece 5 between the knives 2 and 4 is cut.

The guide surfaces 9b and 8b of the plate 9 and the rear guide plate 8 are worn. In FIG. 7B, the hatched portion is a worn portion, and the rear guide plate 8 depends on various conditions such as the hardness of the material constituting each part and the position of the slide guide member 11 provided on the lower knife plate 1. The guide surface 8b tends to wear well.

  When it is necessary to adjust the guide gap 12 due to the wear of each part, the guide gap 12 is narrowed by the thickness reduced by loosening the fastening housing 13 and wearing it. The operation of narrowing the guide gap 12 is performed by moving the rear guide plate 8 forward. At this time, the optimum recess 14 that constitutes the parallel movement locking mechanism 16 so that the optimum guide gap 12 is obtained. Temporary fixing is performed by engaging the convex portion 15 with the concave and convex portions. In this state, the fastening housing 13 is fastened and the slide guide member 11 is fixed to the lower knife plate 1 again (see FIG. 8).

  Therefore, the fine adjustment of the guide gap 12 can be performed with high accuracy by merely engaging the concave and convex portions 14 and 15 provided between the knife clip 10 and the rear guide plate 8 without any skill. It can be done easily and quickly.
