Japanese Patent Laid-Open No. 2001-19186

  Since the sawdust is a consumable item, it must be replaced several times during use. At the time of replacement, the operation of peeling off the crust plate stuck to the support member with the adhesive material sometimes causes the adhesive material to remain on the mounting surface of the support member.

  In addition, the attachment surface of the support member to which the plate is attached has a small area, and the adhesive force for fixing the plate is not always sufficient. For this reason, there is a problem that a paper jam occurs when the paper feeding device is used, and when the jammed printing paper is removed from between the conveying roller and the paper board, the paper board is removed together with the jammed printing paper. .

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a Sabaki unit having a Sabaki member mounting structure that is not easily detached during use but has excellent exchangeability.

The Sabaki unit according to claim 1 is:

  According to the Sabaki unit described in claims 1, 2 and 5, the Sabaki member is detachably attached to the support member by fitting the convex portions and the concave portions of both members. The exchangability is excellent.

  According to the Sabaki unit described in claim 3, the recess of the Sabaki member is a through hole having an inlet and an outlet, and a locking portion for retaining is formed at the tip of the convex of the support member. Therefore, if the convex part of the support member is inserted from the inlet of the hole of the Sabaki member and penetrated to the outlet, the locking part at the tip of the convex part can be locked to the outlet of the hole, In particular, it is hard to come off during use, but it has excellent exchangeability.

  According to the Sakiki unit described in claim 4, corresponding to the plurality of convex portions of the support member, the holes of the Sakiki member are partitioned into a plurality by the partitioning portions. For this reason, since the expansion of the hole is suppressed at least in the part where the partition member is provided, it is difficult for the inconvenience that the printing paper hits the surface of the floating member and the jam occurs.

  According to the Sakiaki unit described in claim 6, a flat chamfered portion with worn corners is provided at the rear edge of the Sakiki member that contacts the conveying roller from the beginning.

It can be used as a side.

1. 1st Embodiment (FIGS. 1-4)
The Sakiki unit described in each embodiment of the present invention including this example is a mechanism provided in a paper feeding device such as a printing device, and a Sakiki member that is a member for rolling printing paper with a conveying roller. Has a structure attached to the support member in a replaceable manner.

  A support member 1 shown in FIG. 1 is continuously provided on a plate-like main body 1a attached to a frame or the like of a sheet feeding device (not shown), and an upper portion of the main body 1a. And a mounting portion 1b formed to bulge toward the paper supply source (left side) so that a recess 2 is formed in the paper supply destination (right side) in the paper direction, and at the tip of the mounting portion 1b. Two convex portions 3 and 3 are provided on the paper supply side (right side).

  The two convex portions 3 and 3 in this example are plate-shaped members having a rectangular cross section provided slightly obliquely above the horizontal plane, and a gap with a predetermined dimension is provided between the two convex portions 3 and 3. In addition, a locking portion 4 for retaining is formed at each tip. As shown in the enlarged view in FIG. 1, the locking portion 4 is a substantially prismatic projection that is formed on the top surface of the tip of the convex portion 3 and continues in the width direction (direction perpendicular to the conveyance direction of the printing paper). .

  1 is a block-like member having elasticity (block-like elastic member), and has two holes 6 as concave portions into which the respective convex portions 3 of the support member 1 are fitted. . These two holes 6 are partitioned by a central partition 7 (wall) that is continuous in the direction of conveyance of the printing paper. Each hole 6 has a substantially rectangular cross section and penetrates forward and backward at the front entrance and the front exit in the transport direction of the printing paper.

  As shown in FIG. 2, each convex portion 3 of the support member 1 is inserted from the inlet of each hole 6 of the rust member 5 and penetrated through the outlet, thereby fitting the rust member 5 to the convex portion 3 of the support member 1. By attaching them together and further, the prismatic locking part 4 is locked to the outlet of the hole 6 and restrained by the surface, so that it can be surely prevented from coming off. In addition, when removing the buckle member 5, the buckle member is elastically deformed and forcibly removed.

  Then, as shown in FIG. 3, the support member 1 is attached to a frame 10 attached to a main body of a paper feeding device (not shown) via a movable mechanism (not shown) to form a Sakiki unit. In FIG. 3, with respect to the conveyance direction of the printing paper, the roller roller 11 that exhibits the same function as the roller member 5 is disposed in the recess 2 of the support member 1 at the rear of the roller member 5. .

  When this Sabaki unit is attached to a predetermined position of the paper feeding device as in the conventional example described with reference to FIG. 9, the Sabaki member 5 of the Sakiki unit is moved by a conveying roller (second in FIG. 9). It is arranged so as to abut against the conveying roller 102) from below with a predetermined pressure. If a plurality of printing papers are supplied in an overlapping manner between the conveying roller that is driven to rotate and the buckling member 5, a single printing paper can be sent out by interleaving them.

  According to this example, by fitting the convex portion 3 of the buckle member 5 and the hole 6 (concave portion) of the support member 1, the buckle member 5 is securely attached to the support member 1 while being removable. Moreover, since the convex portion 3 of the support member 1 passes through the hole 6 of the buckling member 5 and the engaging portion 4 at the tip of the convex portion 3 is engaged with the outlet of the hole 6. Compared with the state where there is no portion 4, it is particularly difficult to come off. Therefore, there is a problem that a paper jam occurs when the paper feeding device is used, and when the jammed printing paper is removed from between the conveying roller and the web member 5, the web member 5 is removed together with the jammed printing paper. Does not occur. Moreover, although it is the state of the fitting of the convex part 3 and the hole 6 and the latching | locking part 4 of the convex part 3 latching to the exit of the hole 6, an operator uses normal tools etc. and normal force As long as the work is performed, the work of removing the buckling member 5 from the support member 1 can be performed without any particular problem, and the exchangability is excellent as compared with the structure in which the material is attached with an adhesive material or the like.

  Furthermore, according to this example, since the hole 6 of the surface member 5 is partitioned into a plurality of portions by the partition portion 7, the width of the hole 6 of the surface member 5 is suppressed at least at a portion where the partition portion 7 is provided. That is, if there is no partition portion 7, the upper wall of the hole 6 is a long member that is continuous in the width direction, does not have a special support structure, and is simply in the state of riding on the inserted convex portion 3, for some reason. In such a case, there is a risk that the printer may be bent upward and block the conveyance path of the printing paper. However, in this example, the hole 6 is divided into two parts by being divided by the partition part 7, and therefore, the upper wall of the hole 6 is coupled to the partition part 7 in the middle in the width direction and thus is suppressed. For this reason, even if a force is applied in the upward bending direction, the actual amount of bending is small, and there is little possibility of inconvenience such as jamming by blocking the printing paper conveyance path.

  FIG. 4 is a perspective view showing a modification member 5a of this example. The rear edge of the upper surface of the surface member 5 is a portion that abuts on the conveyance roller, and a chamfered portion 8 is provided in this portion. If the rear edge does not have such a chamfered portion 8 and the rear edge is a normal corner portion, the corner portion is worn as it is chamfered while being used in contact with the conveyance roller that is driven to rotate. As a result, the desired rolling performance cannot be obtained because of the change from the initial state.

  However, according to this modification, a flat chamfered portion 8 having a worn corner is provided from the beginning on the rear edge of the upper surface of the surface member 5 that contacts the conveying roller. A desired angle performance is obtained by appropriately setting the set angle. The chamfered portion 8 of the surface member 5 is less likely to change its shape even if wear occurs due to use, and therefore the corners are worn with use as in the case of the edged member 5 without the chamfered portion 8 and the surface performance is reduced. Compared to a case where the change is made in a short period of time, the original rolling performance is maintained over a long period of use. This is because the edge of the surface member that contacts the conveying roller is not chamfered, and when the portion of the surface member that comes into contact with the conveying roller has a corner, the surface member comes into contact with the conveying roller by a substantially line. This is because although the wear becomes severe, if the chamfer is chamfered, the surface member comes into contact with the transport roller substantially on the surface, so that the degree of wear is reduced.

2. Second Embodiment (FIGS. 5 and 6)
This example is different from the first example in the structure of the surface member 5b.
In this example, the chamfered member 5b has chamfered portions 8 as described in the modification of the first example provided not only at the rear edge of the upper surface but also at the front edge of the upper surface, the rear edge of the lower surface, and the front edge of the lower surface. It has been. That is, the chamfered portions 8 are all provided on the four long edges of the surface member 5 that is substantially rectangular and elongated in the lateral direction as a whole.

  If it is such a structure, when the contact portion with the conveyance roller or the portion where the fed printing paper collides with wear is used, the reverse member 5b is reversed upside down or left and right and replaced with the support member 1, It can be in the same state as when it is replaced with a new Sabaki member.

  That is, when the upper surface side wears with use and becomes unusable, the upper surface and the lower surface are turned over and replaced with the support member 1, whereby the new lower surface can be used.

  Also, if the rear edge side that comes into contact with the transport roller on the upper surface is worn and cannot be used, the right and left sides are replaced with the support member 1, so that the rear edge side of the same upper surface becomes the front edge side, Since the front edge side can be the rear edge side, a new edge (the chamfered portion 8) of the same surface can be used as a side in contact with the conveying roller.

3. Third embodiment (FIG. 7)
In this example, the concave portion 12 provided in the support member 11 and the convex portion 13 provided in the buckle member 15 are detachably fitted.
As shown in FIG. 7, the upper end portion of the support member 11 extends obliquely upward in the printing paper conveyance direction, and mounting grooves 14 penetrating the left and right end surfaces are formed on the upper surface. Two rectangular recesses 12 are formed on the front surface and the rear surface of the inner surface of the mounting groove 14 respectively. The surface member 15 is a rectangular plate, and its length is equal to the length of the mounting groove 14, and its thickness is substantially equal to the depth of the mounting groove 14. Two rectangular plate-like convex portions 13 corresponding to the concave portion 12 are formed on the front surface and the rear surface on the long side of the rust member 15.

  The bakaki member 15 can be attached to the support member 11 by pushing the bakaki member 15 into the mounting groove 14 of the support member 11 and fitting the convex portion 13 of the bakaki member 15 into the concave portion 12 of the support member 11. Although it is difficult to come off during use, as long as the operator works with a normal force using a normal tool or the like, the operation of removing the buckle member 15 from the support member 11 can be performed without any problem, and is pasted with an adhesive material or the like. Compared to the structure, it has excellent interchangeability.

  Also in this example, when wear or the like occurs in a part of the surface member 15, the surface member 15 can be mounted upside down or can be mounted upside down.

4). Fourth embodiment (FIG. 8)
Similarly to the third embodiment, this example also has a structure in which the concave portion 22 provided in the support member 21 and the convex portion 23 provided in the buckling member 25 are detachably fitted.
As shown in FIG. 8, the upper end portion of the support member 21 extends obliquely upward in the printing paper conveyance direction, and a rectangular attachment groove 24 is formed on the upper surface thereof. One rectangular recess 22 is formed in each of the right and left surfaces of the inner surface of the mounting groove 24. The surface member 25 is a rectangular plate, and the outer shape thereof is the same as the inner shape of the mounting groove 24, and the thickness thereof is substantially the same as the depth of the mounting groove 24. A rectangular plate-like convex portion 23 is formed on the right side and the left side on the short side of the surface member 25 corresponding to the concave portion 22.

  By pressing the surface member 25 into the mounting groove 24 of the support member 21 and fitting the convex portion 23 of the surface member 25 into the concave portion 22 of the support member 21, the surface member 25 can be attached to the support member 21. Although it is difficult to come off during use, as long as the operator works with a normal force using a normal tool or the like, the operation of removing the buckle member 25 from the support member 21 can be performed without any particular problem and is pasted with an adhesive material or the like. Compared to the structure, it has excellent interchangeability.

  Also in this example, when wear or the like occurs in a part of the surface member 25, the surface member 25 can be attached upside down or can be attached upside down.
