However, according to the above configuration, the setting bolt 26 can be replaced and the protruding length can be adjusted relatively freely, which is preferable. It becomes.

  As shown in FIGS. 1 to 3, the insertion shaft 30 is disposed orthogonal to the reference surface 15, and has a male screw portion 32 as a threaded portion in part. The insertion shaft 30 of this embodiment is provided so as to extend vertically above the pedestal 13 and is supported so as to be rotatable about the shaft and movable in the axial direction. Further, a flange portion 33 is provided around the insertion shaft 30 (near the lower end), and a male screw portion 32 is formed below the flange portion 33 (see FIG. 3). A dial-type operation handle 35 is attached to the upper end of the insertion shaft 30 to rotate the insertion shaft 30 about the axis.

  As shown in FIGS. 1 to 3, a predetermined base block 40 and a fine adjustment block 50 are provided by being inserted by the insertion shaft 30. The base block 40 and the fine adjustment block 50 are arranged in parallel in the vertical direction along the axial direction of the insertion shaft 30 through the gap portion 49.

As shown in FIGS. 1 to 3, the base block 40 has a substantially rectangular parallelepiped outer shape, and has a hole portion 42 and a large-diameter hole portion 43 that penetrate vertically. A female screw portion 45 corresponding to the male screw portion 32 of the insertion shaft 30 is formed on the inner wall of the hole portion 42, whereby the insertion shaft 30 and the base block 40 are screwed together. A washer 37 fitted into the large-diameter hole 43 is fixed to the lower end of the insertion shaft 30 with a set screw 38 to prevent the insertion shaft 30 from coming off. A contact portion 47 is formed on the front lower surface of the base block 40 so as to form a flat surface parallel to the reference surface 15. The base block 40 is positioned by the contact between the contact portion 47 and the top portion 26a of the setting bolt 26 in the stopper 20.

  As shown in FIGS. 1 to 3, the fine adjustment block 50 has a slightly thicker outer shape in plan view that is slightly larger than the base block 40, and engages with the guide portion 70 in two directions. Engagement parts 52 and 53 are formed. Similar to the base block 40, the fine adjustment block 50 has a vertically extending hole 55 and a large-diameter hole 56, and the insertion shaft 30 is rotatably passed through the hole 55. A flange portion 33 of the insertion shaft 30 is fitted into the large-diameter hole portion 56 via a washer 39, and the fine adjustment block 50 is sandwiched between the flange portion 33 and a measurement indicator 65 (described later). As a result, the insertion shaft 30 is supported so as not to be relatively movable in the axial direction.

  At the rear end of the fine adjustment block 50, a bent portion 60 as shown in FIGS. 1 to 3 extends downward with the same width as the engaging portion 53. The bending portion 60 includes gripping portions 62 and 62 on both sides, and the base block 40 can be slidably moved up and down in a recess formed thereby. The gripping portion 62 restricts the base block 40 from rotating following the axis of the insertion shaft 30. The bending portion 60 includes a predetermined sliding support surface 63 on the surface opposite to the gripping portion 62, and a mounting portion 64 on which a position adjusting member 80 can be fixed is formed in a protruding shape on a part of the sliding support surface 63. Is formed.

The guide unit 70 guides the base block 40 and the fine adjustment block 50 so as to be movable in the axial direction of the insertion shaft 30. In this embodiment, as shown in FIGS. The guide walls 72 and 73 that are appropriately fixed are formed in a substantially L shape in plan view. Guide grooves 72a and 73a that engage with the engaging portions 52 and 53 of the fine adjustment block 50 and form a vertical plane with the reference walls 15 are respectively provided in the inner wall surfaces of the guide walls 72 and 73 so as to be recessed vertically. Thus, the fine adjustment block 50 (and the base block 40) is guided in the vertical direction while maintaining the horizontal level. The bending portion 60 extending to the fine adjustment block 50 is also guided while the sliding support surface 63 is slidably supported by the groove bottom of the guide groove 73a. The sliding support surface 63 makes it easy for the fine adjustment block 50 to be kept horizontal and allows the position adjustment member 80 to move stably up and down.
Long holes 72b and 73b are further penetrated in the groove bottoms of the guide grooves 72a and 73a, respectively, and a clamp lever 75 as a clamping means is connected through one long hole 72b. The other long hole 73b is vertically movably penetrated to be exposed to the outside of the guide wall 73. A predetermined position adjusting member 80 is fixed to the exposed portion of the attachment portion 64. In FIGS. 1 and 3, reference numeral 73 c denotes an auxiliary groove that is recessed in the outer wall surface of the guide wall 73. By fitting the position adjustment member 80 in such an auxiliary groove 73c, the vertical movement of the position adjustment member 80 can be more easily stabilized.

  In the position adjustment apparatus 10 of the present embodiment, a predetermined measurement indicator 65 is attached to the fine adjustment block 50 as shown in FIGS. The measurement indicator 65 measures and displays the movement amount of the fine adjustment block 50 based on the rotation amount of the insertion shaft 30, and includes a measurement indicator main body 66 and a measurement ring 67 that are inserted through the insertion shaft 30. The measurement indicator main body 66 is fixed on the fine adjustment block 50 using a torque pin (not shown) or the like, but the measurement ring 67 is fixed to the insertion shaft 30 with a set screw 68 (see FIG. 3). And is configured to be rotatable together with the insertion shaft 30. The measurement display body 66 is provided with a known gear transmission mechanism connected to the measurement ring 67 and a digital or analog counter (not shown), and the insertion shaft 30 measured by the measurement ring 67 is provided. The amount of vertical movement of the fine adjustment block 50 obtained by considering the screw pitch of the male thread portion 32 of the insertion shaft 30 based on the number of turns and the rotation angle is the display portion 69 (FIG. 2) of the measurement indicator main body 66. Displayed).

In using the position adjusting device 10 configured as described above, the base block 40 is first positioned at a basic height position. The positioning of the base block 40 is performed by abutting and supporting the contact portion 47 of the base block 40 on the setting bolt 26 of the stopper means 20. By rotating the rotating plate 23 of the stopper 20, a setting bolt 26 having a desired protruding length is selected.

The base block 40 is configured to move integrally with the insertion shaft 30, the fine adjustment block 50, and the like. The base block 40 is temporarily raised while the rotating plate 23 is rotated, and the base block 40 is moved upward. Is preferably separated from the stopper 20. When a desired setting bolt 26 is set directly below the contact portion 47 of the base block 40, the base block 40 and the like are lowered and the contact portion 47 is placed on the top portion 26a of the setting bolt 26. At this time, in the present embodiment, the fine adjustment block 50 (engaging portion 52) can be slidably fastened to the guide portion 70 (guide wall 72) using the clamp lever 75. . As a result, the fine adjustment block 50 is stably supported by the guide portion 70, so that the position of the position adjustment member 80 connected to the fine adjustment block 50 can be more easily finely adjusted.

In the state where the base block 40 is positioned as described above, the position adjusting member 80 is located at a predetermined distance d from the reference surface 15 (see FIG. 3). When it is necessary to finely adjust the level position of the position adjusting member 80 while the carton assembling machine M is in operation (or when changing the type (size) of the carton C), the insertion shaft is connected via the operation handle 35. What is necessary is just to rotate 30 about the axis | shaft of a forward direction or a reverse direction. The rotation operation of the operation handle 35 is preferably performed while applying a slight downward pressing force so that the positioning state of the base block 40 is maintained.

As the insertion shaft 30 rotates, the base block 40 remains stopped, but the insertion shaft 30 is screwed up and down with respect to the base block 40. Thereby, the fine adjustment block 50 moves in the vertical direction together with the insertion shaft 30 so as to be separated from or approach the base block 40. The bent portion 60 slides in the vertical direction between the base block 40 and the guide groove 73a of the guide wall 73, and accordingly, the attachment portion 64 and the position adjusting member 80 are also moved in the vertical direction.

In this way, the distance d from the reference surface 15 of the position adjusting member 80 can be finely adjusted freely. In the case of the carton assembly machine M, the range that needs fine adjustment is usually about 1 to 2 mm at the maximum. In the present embodiment, as described above, since the predetermined measurement indicator 65 is attached, fine fine adjustment can be performed very easily while visually confirming the movement amount of the fine adjustment block 50 (position adjustment member 80). It is like that.

When the basic position of the position adjusting member 80 is to be largely adjusted, such as when changing the type (size) of the carton C, the clamp lever 75 is released and the base block 40 is moved together with the insertion shaft 30, the fine adjustment block 50, etc. After raising again, the rotating plate 23 of the stopper means 20 may be rotated, and an appropriate setting bolt 26 may be selected again. The fine adjustment of the position adjusting member 80 after resetting the setting bolt 26 is as described above. If the setting bolt 26 or the nut 27 is provided with a mark such as a symbol or a color according to the type (size) of the carton C, the selection of the setting bolt 26 can be further simplified.

  According to the position adjusting device 10 described above, the position of the position adjusting member 80 can be easily finely adjusted without taking much trouble such as a large setup change. No special techniques or special skills are required for this fine adjustment, and anyone can easily make fine adjustments. Moreover, since the position adjusting device 10 has the configuration as described above, the position of the position adjusting member 80 can be finely adjusted with high accuracy.

  Further, according to the position adjusting device 10, since the stopper means 20 includes the rotating plate 23 and the plurality of setting bolts 26, the position of the position adjusting member 80 can be easily changed when changing the type (size) of the carton C. And can be adjusted quickly. The position adjustment device 10 finely adjusts the position of the position adjustment member 80 via the fine adjustment block 50 after the base block 40 is positioned at the basic height position by the stopper 20. Therefore, it is not necessary to rotate the insertion shaft 30 many times when the basic position of the position adjusting member 80 is adjusted or finely adjusted. In general, the carton assembling machine M requires a total of 10 to 20 position adjusting members 80. In recent years, the varieties (sizes) of cartons C produced by one carton assembling machine M tend to be diversified. By using the position adjusting device 10, the entire machine leads to significant labor reduction and speed up.

Note that the position adjustment device 10 described above manually performs a series of operations. However, by adding an appropriate configuration as necessary, all or part of these operations may be automated. Good.

The description of the above embodiment does not limit the present invention, and various modifications and design changes can be made without departing from the spirit of the present invention.

  For example, the size, shape, and the like of the stopper means 20, the insertion shaft 30, the base block 40, the fine adjustment block 50, the guide portion 70, and the like can be changed as appropriate. In the above embodiment, the reference surface 15 is formed on the upper surface of the pedestal 13, but the reference surface 15 may be formed at an arbitrary position. The reference surface 15 does not necessarily have to be configured horizontally, and may be a vertical surface or an inclined surface (in this case, the position adjusting device 10 is disposed horizontally or obliquely).

In the above embodiment, the base block 40 is indirectly guided by the guide portion 70 via the bent portion 60 extending to the fine adjustment block 50, but is directly guided by the guide portion 70. It can also be set as a structure. FIG. 4 shows a position adjusting device 110 configured as described above as another embodiment (the same components as those in the above embodiment are denoted by the same reference numerals; the same applies to the following drawings).

As shown in FIG. 4, in the position adjusting device 110, an engaging portion 146 is formed at the rear of the base block 140, and the engaging portion 146 is slightly narrower than the guide groove 73a. By extending to the groove bottom, the base block 140 can slide up and down in the guide groove 73a. Further, in the position adjustment device 110, the bent portion 60 as in the above embodiment is not provided, and the rear end of the fine adjustment block 150 partially extends through the long hole 73b and extends horizontally. Thus, the attachment portion 64 is formed.

Even in such a position adjusting device 110, as the insertion shaft 30 rotates, the attachment portion 64 provided continuously to the fine adjustment block 150 is moved in the vertical direction, and the position adjusting member 80 is moved from the reference surface 15. The distance d can be finely adjusted freely.
The rear end of the fine adjustment block 150 may be extended upward to provide a bent portion having a predetermined sliding support surface. By providing such a bent portion, the fine adjustment block 150 can be easily kept horizontal, and the position adjustment member 80 can be stably moved up and down.
On the other hand, the rear end of the fine adjustment block 150 is extended downward to provide the bent portion 60 as in the above embodiment, and the holding portion 62 for holding the bent portion 60 slidably. And the sliding support surface 63 that is slidably supported by the guide portion 70 (guide groove 73a), the base block 40 can be easily formed in a simple shape with a minimum size, The position adjusting device 10 can be reduced in size. In addition, since no frictional resistance is generated between the base block 40 and the guide portion 70 (guide groove 73a), the base block 40 and the fine adjustment block 50 can be moved up and down together very smoothly. Further, since the base block 40 can be prevented from rattling in the horizontal or vertical direction accompanying the rotation of the insertion shaft 30, fine adjustment of the position adjusting member 80 can be easily performed accurately.

Moreover, in the said embodiment, although the insertion shaft 30 and the base block 40 are screwed together, it can also be set as the structure by which the insertion shaft 30 and the fine adjustment block 50 are screwed together. FIG. 5 shows a position adjusting device 210 configured as described above as still another embodiment.

As shown in FIG. 5, in the position adjustment device 210, a male screw portion 232 is formed above the flange portion 233 of the insertion shaft 230, and the base block 240 and the fine adjustment block 250 are inserted through the gap portion 249. Are arranged along the axial direction.
The base block 240 has an upper and lower through hole 242, and the insertion shaft 230 is rotatably inserted in the hole 242. A flange portion 233 is fixed to the upper surface of the base block 240 via a washer 239, and a washer 237 fitted into the lower surface of the base block 240 is fixed to the lower end of the insertion shaft 230 with a set screw 238. The base block 240 is supported between the flange portion 233 and the washer 237 so as not to move relative to the insertion shaft 230 in the axial direction.
The fine adjustment block 250 has a hole portion 255 penetrating vertically, and a female screw portion 257 corresponding to the male screw portion 232 of the insertion shaft 230 is formed on the inner wall of the hole portion 255. As a result, the insertion shaft 230 and the fine adjustment block 250 are screwed together. In addition, a predetermined bent portion 60 extends downward from the rear end of the fine adjustment block 250.

Also in such a position adjusting device 210, it is possible to finely adjust the distance d of the position adjusting member 80 from the reference plane 15. That is, when the insertion shaft 230 is rotated about the forward direction or the reverse direction by the rotation operation of the operation handle 35, the fine adjustment block 250 moves away from the base block 240 along with the rotation of the insertion shaft 230. Or it is screwed to approach and moves up and down. At this time, in the position adjusting device 210, the vertical positions of the insertion shaft 230 and the base block 240 do not change, but the bent portion 60 slides in the vertical direction between the base block 240 and the guide groove 73a of the guide wall 73, Accordingly, the attachment portion 64 and the position adjustment member 80 are also moved in the vertical direction.

  Moreover, in the said embodiment, although the guide part 70 is comprised by the guide wall (72, 73) which makes planar view substantially L shape, these guide walls are provided only in one direction, two opposing directions, You may make it provide in three directions. The guide part 70 can also be comprised by the guide wall which makes continuous or discontinuous appropriate shapes, such as planar view curved shape. The guide unit 70 may have a configuration other than the guide wall. For example, one or two or more cylinder pipes suspended from the reference surface 15 may be used as the guide unit 70. The base block 40 and the fine adjustment block 50 may be appropriately engaged with the guide block 70 according to the form of the guide portion 70. As guide means for guiding the base block 40 and the fine adjustment block 50, appropriate protrusions, rails, fitting holes, etc. may be employed instead of the guide grooves (72a, 73a).

In the above embodiment, an example in which the position adjustment device 10 is provided in the carton assembly machine M has been described. However, the present invention is not limited to this, and other automatic packaging machines, machine tools, and the like that require the position adjustment member 80. Needless to say, the present invention can be widely applied to industrial machines.
