Description

  The present invention relates to a transport device that supports and propels a carrier that supports an object to be transported by driving rollers disposed at appropriate intervals along a transport path.

  Each drive roller in this type of transport device is pivotally supported between the frames on both sides of the transport path, and hangs a pair of left and right roller parts that support the carrier and a belt that interlocks the front and rear drive rollers. A pulley unit for tensioning and cannot be disclosed by citing patent literature, but in this type of conventional conveying device, a rotating shaft to which the pair of left and right roller units and a pulley unit are attached Both ends of the frame were supported on the both side frames so as to be rotatable by bearings.

  In the conventional configuration as described above, when performing maintenance work such as replacement of a belt that interlocks the front and rear drive rollers with each other or replacement of a worn drive roller, the bearings that support both ends of the rotating shaft are removed from both side frames. Although it is necessary, in order to extract the bearings from both ends of the rotating shaft so that the rotating shaft can be handled in the upper space between the both side frames, the bearings must be mounted on the both side frames. . When adopting such a configuration, almost the whole of the rotating shaft and the pair of left and right rollers and pulleys attached to the rotating shaft protrude above the both side frames. It is necessary to attach a detachable side cover on the top, which leads to a significant increase in the cost of the entire facility. In addition, if a configuration is adopted in which bearings are attached to the side surfaces of both side frames to support the rotating shaft, almost all of the rotating shaft and a pair of left and right roller portions and pulley portions attached to the rotating shaft can be accommodated between the side frames. However, when removing the rotating shaft for maintenance work, move the rotating shaft in the axial direction with the bearing removed, and remove it from the frames on both sides. There must be. In order to make it possible to remove the rotating shaft, the fixing of the pair of left and right roller portions and the pulley portion with respect to the rotating shaft is released, and the rotating shaft is axially moved with respect to the pair of left and right roller portions and pulley portions. In addition to being configured to be able to be pulled out, at least one of the both side frames requires a working space wider than the length of the rotating shaft, in which the rotating shaft can be pulled out in the axial direction, The floor usage efficiency is significantly reduced.

The drive roller body 11 is adjacent to a pair of left and right roller portions 13 and 14 that support the carrier 23 in the front-rear direction. And a pulley portion 15 for tensioning a belt 8 for interlocking the drive roller main bodies 11 to be engaged with each other. Both side frames 2a and 2b are free to move both ends of the fixed shaft 12 in the axial direction. A support hole 20 is provided for supporting the fixed frame 12 in a fixed position, and the support hole 20 of at least one frame includes a lower half 20a that supports the end of the fixed shaft 12 in a fixed position and a support of the other frame. The fixed shaft 12 with one end portion removed from the hole 20 is composed of an upper half portion 20b for allowing the one end portion to be in an inclined posture positioned above the other frame, and supports the both side frames 2a and 2b. Locking means (notch groove 19, locking plate 21 and bolt nut 22) for stopping the axial movement of the fixed shaft 12 supported at both ends in the hole 20 is provided.

  In carrying out the present invention having the above-described configuration, specifically, as described in claim 2, the pulley portion 15 of the drive roller body 11 is one of the pair of left and right roller portions 13 and 14. The drive roller main body 11 is configured by providing a cylindrical shaft 16 that integrates one roller portion integrated with the pulley portion 15 and the other roller portion, and is integrated and integrated in the axial direction. Both ends of the drive roller body 11 can be supported on the fixed shaft 12 via bearings 17. In this case, as described in claim 3, the cylindrical shaft 16 can be inserted to both ends of the drive roller body 11, and both ends of the cylindrical shaft 16 can be supported on the fixed shaft 12 by bearings 17.

  According to a fourth aspect of the present invention, the locking means includes the notch groove 19 provided on the peripheral surface of the end of the fixed shaft 12 and the notch groove 19 in a state where the side is fitted. The locking plate 21 can be configured to be detachably fixed to the frames 2a and 2b on the upper side of the fixed shaft 12.

  Further, according to a fifth aspect of the present invention, the pair of left and right roller portions 13 and 14 includes one flanged roller portion 13 and the other wrinkleless roller portion 14, and the carrier 23 includes one wrinkle roller portion. The one vertical frame member 24 fitted to and supported by the attached roller portion 13, the other vertical frame member 25 supported by the other wrinkleless roller portion 14, and the two vertical frame members 24, 25 are connected to the roller portion 13. , 14 connecting horizontal frame members 26a to 26c that are connected at a height that does not interfere with each other, and two front and rear frames that are mounted so as to be adjustable in the longitudinal frame material length direction across the vertical frame members 24 and 25.

From the attachment 33) It can be formed.

  According to the conveying device of the present invention having the above-described configuration, when the driving roller is removed for maintenance work, the entire driving roller is removed in a state where the locking means that stops the axial movement of the fixed shaft is released. Slightly move in the axial direction, pull out one end of the fixed shaft from the support hole of one frame, and then lift the end of the fixed shaft that is extracted from the support hole to a height above the frame on the same side The entire drive roller may be moved in the axial direction with the tilted posture so that the entire drive roller is inclined and the other end portion of the fixed shaft is pulled out from the support hole of the other frame in this state.

  That is, according to the configuration of the present invention, the drive roller supported between the left and right side frames can be removed slightly above the left and right side frames by moving the drive roller slightly in the axial direction. Can be supported between the left and right frames. Therefore, since the entire drive roller can be accommodated between the left and right side frames, there is no need to attach a side cover on the upper side of the left and right side frames to ensure safety, and for maintenance work. As with the case where both ends of the drive roller are pivotally supported on the upper side of the left and right side frames, the drive roller can be easily attached and removed in the upper space of the left and right side frames. In addition, the conventional problem of having to secure a wide working space for extracting the rotating shaft can be solved, and the use efficiency of the floor surface can be improved. In addition, when removing and installing the drive roller, the fixed shaft and the drive roller body fitted and supported on the fixed shaft can be handled as a single unit, and the rotating shaft and the roller unit or pulley unit can be relatively moved as in the past. There is no need to extract in the axial direction, and in this respect, the work can be efficiently performed and the cost of the drive roller itself can be reduced.

  In addition, according to the structure of Claim 2, compared with the case where a pair of left-right roller part and pulley part are separately supported by the fixed position of a fixed shaft with a bearing, the number of bearings can be reduced, and drive The roller can be configured at low cost. In this case, by adopting the configuration according to claim 3, a drive roller body having sufficient bending strength can be easily and inexpensively manufactured.

  Further, according to the configuration of claim 4, the locking means for stopping the axial movement of the fixed shaft can be implemented at a low cost with a simple configuration, and not only the axial movement of the fixed shaft is stopped, The fixed shaft can also be prevented from moving to the upper half of the support hole, that is, lifted upward, and the fixed shaft and thus the driving roller can be reliably installed at a fixed position.

  Furthermore, according to the structure of Claim 5, a carrier can be comprised easily and lightly from a commercially available frame material, and the support position can be freely changed back and forth and left and right according to the size of the conveyed object. Can be adjusted. In addition, simply sticking a belt-like material that has a large frictional force against the peripheral surface of each roller part of the drive roller to the belt-like bottom surface of the left and right vertical frame members supported by the drive roller.

The gantry 1 may have any structure except the left and right side frames 2a and 2b which are essential requirements.

  A driving roller 7 is pivotally supported between the left and right frames 2a and 2b of the gantry 1 at appropriate intervals in the frame length direction, and the driving rollers 7 adjacent to each other in the front-rear direction are linked to each other by a timing belt 8. The driving roller 7 positioned at one end is interlocked and connected by a timing belt 10 and a motor 9 supported inside one end of the gantry 1.

  As shown in FIG. 5, the drive roller 7 includes a combination of a drive roller body 11 and a fixed shaft 12. The driving roller main body 11 includes a roller portion 13 with a flange at one end, a roller portion 14 without a wrinkle at the other end, a pulley portion 15 disposed between both roller portions 13 and 14, and a cylinder that concentrically integrates the three members. It is composed of a shaft 16. In this illustrated example, a cylindrical shaft 16 having a length substantially equal to the distance between the outer surfaces of the pair of left and right roller portions 13 and 14 is used, and the flanged roller portion 13 is fitted and fixed to one end of the cylindrical shaft 16. A pulley portion 15 having two belt hooking portions 15a and 15b arranged in parallel in the axial direction is integrally formed on the inner roller portion 14 in a concentric manner, and the wrinkleless roller portion 14 and the pulley portion 15 are integrated. A component is externally fitted and fixed to the other end of the cylindrical shaft 16, and bearings (radial bearings) 17 are fitted and fixed to both ends of the cylindrical shaft 16.

  As shown in FIGS. 4 and 7, the left and right frames 2 a and 2 b of the gantry 1 are made of grooved steel so that the groove portions face outward, and the fixed shaft 12 is formed on the left and right frames 2 a of the gantry 1. , 2b is slightly longer than the inner width between the left and right frames 2a, 2b. As shown in FIG. 5, the fixed shaft 12 is inserted into the cylindrical shaft 16 (bearings 17 at both ends) of the driving roller body 11 and protrudes from the both ends of the driving roller body 11 by the same length, for example, a bearing. The drive roller body 11 cannot be moved in the axial direction with respect to the fixed shaft 12 but can only be rotated by attaching a stop ring 18 adjacent to the outside of the shaft 17 in a circumferential groove provided on the fixed shaft 12. It has been. Further, a notch groove 19 is formed in the fixed shaft 12 in the same direction at a position entering the inside from both ends.

  As shown in FIGS. 6 and 7, support holes 20 are provided in the left and right frames 2 a and 2 b of the gantry 1 at each position where the drive roller 7 is pivotally supported. As shown in FIG. 7B, each of the support holes 20 includes an upper open semicircular lower half 20a that supports the end of the fixed shaft 12 at a fixed position, and a lower open half that has a larger diameter than the lower half 20a. It is formed from a circular upper half 20b.

  The timing belt 8 for interlockingly connecting the driving rollers 7 adjacent to each other in the front and rear directions has an appropriate tension between the pulley portions 15 of the driving rollers 7 adjacent to the front and rear when the timing belt 8 is supported by the pair of left and right support holes 20. The length that can be hung is set. Therefore, no tension adjusting means is used in combination with each timing belt 8.

  Each driving roller 7 having the above-described configuration has a wrinkle-free roller portion 14 between the left and right side frames 2a and 2b in order from one end of the left and right side frames 2a and 2b, for example, the driving roller 7 on the side directly interlocked with the motor 9. They are assembled in the same direction (in FIG. 3, on the side frame 2b side). More specifically, the driving roller 7 at the end on the motor 9 side is assembled in a state where the timing belt 8 and the timing belt 10 are loosely fitted. The procedure is as follows. For example, as shown in FIG. 6A, one end portion of the fixed shaft 12 protruding from one end on the side far from the pulley portion 15 corresponds to the support hole 20 that forms a pair on the left and right frames 2a and 2b. The support hole 20 on the side to be inserted is inserted obliquely from above. At this time, due to the presence of the large-diameter upper half portion 20b of the support hole 20, one end portion of the fixed shaft 12 can be inserted without difficulty. Then, as shown in FIG. 6B, the driving roller 7 is placed in a horizontal posture so that the driving roller body 11 and the other end of the fixed shaft 12 enter between the left and right frames 2 a and 2 b, and the timing belt 10 is placed in the driving roller 7. The drive roller 7 is moved in the axial direction so that the other end of the fixed shaft 12 is inserted into the support hole 20 on the corresponding side in a state of being stretched between the belt hook 15a of the pulley 15 and the pulley on the motor 9 side. Slide. Also at this time, due to the presence of the large-diameter upper half 20b of the support hole 20, the other end of the fixed shaft 12 can be easily inserted into the support hole 20 in a state where the timing belt 10 is tensioned.

  With the drive roller 7 spanned between the left and right frames 2a and 2b as described above, the position of the drive roller 7 is adjusted in the axial direction, and the notch grooves 19 at both ends of the fixed shaft 12 are respectively upward and left and right. Adjacent to the inner side surfaces of both side frames 2a, 2b. In other words, the notch groove 19 is formed so that the interval between the outer sides thereof is substantially equal to the inner width between the left and right frames 2a and 2b. Then, a rectangular locking plate 21 having a lower side portion fitted in each notch groove 19 is detachably fixed to the inner side surfaces of the left and right frames 2a and 2b with bolts and nuts 22, so that the drive roller 7 (fixed shaft) is fixed. 12) is fixed so as not to move in the axial direction with respect to the left and right frames 2a and 2b. Note that bolt holes are provided in advance in the locking plate 21 and the left and right side frames 2a and 2b so as to match each other. Of course, the locking plate 21 is provided with screw holes, and bolts inserted from the outside of the left and right side frames 2a, 2b are screwed into the screw holes of the locking plate 21 to attach the locking plate 21. Also good.

  If the motor 9 can be installed in the direction in which the timing belt 10 is stretched, the timing belt 10 that interlocks the first driving roller 7 on the motor 9 side with the motor 9 is connected to the driving roller 9. The length of the timing belt 10 may be adjusted so that the tension of the timing belt 10 is adjusted by adjusting the position of the motor 9 after the driving roller 7 is supported.

  Each of the second and subsequent drive rollers 7 from the motor 9 side can also be supported between the left and right frames 2a and 2b as described above, but one drive roller 7 except for the last drive roller 7 is provided. The timing belt 8 is loosely fitted in advance, and when the driving roller 7 is supported between the left and right side frames 2a and 2b, the timing belt 8 that is already loosely fitted on the previous driving roller 7 is supported. The belt drive portion 7 of the pulley 15 in the front drive roller 7 and the belt drive portion 15a of the pulley 15 in the rear drive roller 7 to be supported are fitted to each other. In this manner, it is supported between the left and right frames 2a and 2b. As a result, the timing belt 8 stretched between the supported drive roller 7 on the rear stage and the front drive roller 7 supported on the front is moderately tensioned, and both the front and rear drive rollers 7 are connected to the timing belt 8. Are securely linked together.

  As described above, each driving roller 7 supported at a predetermined interval between the left and right side frames 2a and 2b has a part of the peripheral surface of the flanged roller part 13 and the wrinkleless roller part 14 on the left and right side frames 2a, 2a, 2b. In this state, it protrudes slightly above the upper surface of 2b, and all the drive rollers 7 can be rotated by the motor 9 at the same peripheral speed, and the assembly of one conveyor unit is completed. Although not shown in the drawings, a cover plate having an opening through which a part of the peripheral surface of each roller portion 13, 14 protrudes between the upper surfaces of the left and right side frames 2a, 2b, or the left and right side frames 2a, 2b, A work floor can be installed on the outside of 2b flush with the cover plate.

  It is necessary to remove the driving roller 7 in order to perform maintenance work such as replacement of the timing belts 8 and 10, replacement of the driving roller 7 itself, or replacement of the driving roller body 11 including the roller portions 13 and 14 in the driving roller 7. When this occurs, the drive roller 7 can be removed from between the left and right frames 2a, 2b in a procedure that is exactly the reverse of the procedure for assembling. That is, the locking plate 21 constituting the locking means for locking the fixed shaft 12 to the left and right frames 2a and 2b is removed from the left and right frames 2a and 2b, and the entire drive roller 7 is moved as shown in FIG. 6B. One end of the fixed shaft 12 is moved in the axial direction, for example, one end close to the pulley portion 15 is extracted inward from the support hole 20 of one frame 2a, and the drive roller 7 and the previous drive roller 7 are interlocked. With the timing belt 8 to be coupled removed from the pulley portion 15, the drive roller 7 is in a slanted inclination posture by lifting one end portion of the fixed shaft 12 that has become free, as shown in FIG. 6A. In this state, the drive roller 7 may be moved in the axial direction so that the end of the opposite fixed shaft 12 is extracted from the support hole 20 of the frame 2b.

  As shown in FIG. 5, the drive roller body 11 in the above embodiment uses a plurality of axial circumferential grooves 16a formed on the outer peripheral surfaces of both ends of the cylindrical shaft 16, and uses the cylindrical shaft 16 as a core material. The wrinkle-free roller portion 14 and the pulley portion 15 are formed integrally with the cylindrical shaft 16 and the wrinkled roller portion 13 is formed integrally with the cylindrical shaft 16, but the wrinkled roller configured separately from the cylindrical shaft 16 The portion 13, the wrinkle-free roller portion 14, and the pulley portion 15 can be externally fitted to the cylindrical shaft 16 and both can be coupled by appropriate coupling means such as keying. Of course, the drive roller body 11 is not limited to that of the above embodiment.

  For example, as shown in FIG. 8A, the drive roller main body 11 is configured by concentrically connecting a flanged roller part 13 and a pulley part 15 and a flanged roller part 13 to both ends of a cylindrical shaft 16. As shown in FIG. 8B, the wrinkleless roller portion 14, the pulley portion 15, and the cylindrical shaft 16 are integrally formed, and the wrinkled roller portion 13 is attached to the free end portion of the cylindrical shaft 16. The drive roller main body 11 can also be configured by concentric connection. The integrated component of the wrinkle-free roller portion 14 and the pulley portion 15 and the connecting method of the roller portion 13 with the wrinkle and the end portion of the cylindrical shaft 16 are also fitted to each other in the axial direction as shown in FIG. In addition to the fitting coupling structure that couples to each other, a flange coupling structure may be used. Of course, although the example using the integral component of the wrinkle-free roller part 14 and the pulley part 15 was given, you may integrally mold the pulley part 15 in the roller part 13 with a flange. Furthermore, the roller portion 13 with a flange, the roller portion 14 without a flange, and the pulley portion 15 can all be independent components, and these can be concentrically fixed to the cylinder shaft 16. Further, in some cases, the pulley portion 15 can be arranged outside the roller portion 13 with a flange or the roller portion 14 without a flange, and the two belt hook portions 15a and 15b necessary for the pulley portion 15 are separate parts. It is also possible to configure them by attaching them to the cylinder shaft 16 in a state where they are adjacent to each other or at positions separated from each other.

  In the above embodiment, the locking means of the fixed shaft 12 is constituted by the notch groove 19 and the locking plate 21 provided at positions near both ends of the fixed shaft 12 and the bolt nut 22 for mounting the locking plate. However, it is not limited to this.

A pair of left and right supporting horizontal frame members 27a and 27b, and a pair of left and right mounting units mounted on the supporting horizontal frame members 27a and 27b so that the mounting position can be adjusted in the length direction of the horizontal frame member. It is comprised from the support | pillar 28a, 28b for a to-be-conveyed object.

  As illustrated in FIG. 9, the left and right vertical frame members 24 and 25 and the supporting horizontal frame members 27a and 27b have, for example, a rectangular cross section (the ratio of the long side to the short side is 2: 1) and the short side portion. For example, a mold member made of aluminum or the like formed so that one member and two member mounting grooves 29 are continuous over the entire length of the long side portion can be used, and the connecting lateral frame members 26a to 26c can be used. The support support columns 28a and 28b are formed in such a way that the cross-sectional size is a square cross-section of the half of the mold material, and one member mounting groove 29 is provided on each side continuously over the entire length. A mold material made of aluminum or the like can be used. When the carrier 23 is constituted by such a combination of mold materials, each mold material is loosely fitted inside the angled connecting fitting 30 and the member mounting groove 29 so as to be movable only in the mold material length direction. 31 and a bolt 32 that couples them can be used to easily assemble one having an arbitrary size, and the two front and rear supporting horizontal frame members 27a and 27b can be adapted to the size of the object to be conveyed W. It is also possible to easily change the interval and change the interval between the pair of left and right conveyed object support members composed of the conveyed object supporting columns 28a and 28b and the conveyed object supporting attachment 33.

  The cross-sectional shape of the mold shown in FIG. 9 is an example, and is not limited to the illustrated one. In addition, the angle-shaped connecting bracket 30 used for the assembly is also one bolted on both sides, one bolted on one side, two bolted on the opposite side, and two bolts on both sides (not shown). It can be used properly according to the place of use, such as a stop. In addition, as shown in FIGS. 1-3, the to-be-conveyed object support attachment 33 matched with the shape of the to-be-supported part of the to-be-conveyed object W is attached to the upper end of each to-be-conveyed object support | pillar 28a, 28b. .
