2. Description of the Related Art In a photographic processor, a known photographic paper is produced by sequentially passing a photographic printing paper, an exposed photographic film, or an exposed photosensitive lithographic printing plate through a development processing tank, a fixing processing tank, a washing tank, etc. Processing is performed. In each of these processing tanks, a large number of resin rollers are arranged along the conveying path for conveying the printing paper, the photographic film, or the exposed photosensitive lithographic printing plate. These rollers require relatively small transport torque, but chemical resistance and light weight are required.

Many rollers are used in photographic processors and the like. For this reason, it is necessary to manufacture a large number of rollers, and an automatic manufacturing line has come to be used. In this automatic manufacturing line, a large number of machines necessary for processing and assembling the rollers are arranged in a plane, and the work is moved between the machines to automatically perform the processing and the assembly. Such an automatic production line is equipped with a pipe supply device for supplying the pipes, which are the main parts of the rollers, one by one.

[0005]

Since such a pipe supply device is provided with a large number of shelves, when the pipes are supplied one by one, after the pipes on one shelf have been taken out, It was necessary to change the shelves. This shelving change operation was performed manually or, when automatically performed, by power. For this reason, there is a problem that it is not possible to fully automate manual shelf changing operations. Further, there is a problem that the configuration becomes complicated when automatically performed by using power.

The present invention is intended to solve the above problems,
It is an object of the present invention to provide a rod-shaped object supply device that does not use power or manually change shelves. The rod-shaped object is not limited to a pipe, but includes a columnar shape, a prismatic shape, and the like that can move by rolling or sliding on an inclined shelf plate of the supply device.

[0007]

In order to achieve the above object, the rod-shaped object supply device according to claim 1 is attached to the lower end portion of each shelf member, and has a retracted position in which it stands up by its own weight. A movable guide member that is rotationally displaced between a guide position in which the rod-shaped object that has moved from the shelf member rotates and is inclined by the weight of the rod-shaped object, and an upper portion of the movable guide member opposite to the shelf member. A locking member that is provided at the tip portion and that prevents the rod-shaped object from falling off from the tip portion at the guide position, and the movable of other shelf members other than the lowest shelf member of the plurality of shelf members. A locking position which is arranged in a position close to the guide member and projects into the movement path of the rod-shaped object in the shelf member to lock the rod-shaped object, and an unlocking position in which the rod-shaped object retreats from the movement path to allow the movement of the rod-shaped object Change between position A stopper member that is freely urged to reach the locking position, the stopper member and the movable guide member immediately below the stopper member are linked, and the guide position of the movable guide member From the retracted position to the retracted position by moving the stopper member from the locked position to the unlocked position.

According to a second aspect of the present invention, in the apparatus for supplying a rod-shaped object according to the first aspect, the movable guide member is rotatably attached to an attachment shaft, and the interlocking means is provided on the movable guide member. Between a ratchet that is fixed to the mounting shaft in the vicinity and a blocking position that is rotatably mounted on the movable guide member and that blocks the rotation of the ratchet, and a blocking release position that cancels the blocking of the ratchet rotation. And the stopper member is unlocked from the locked position by the rotational shift of the pawl member which is moved to the blocking position by its own weight when the movable guide member is in the guide position and the mounting shaft of the movable guide member. It is composed of a shift transmission unit which is placed in a position.

According to a third aspect of the present invention, in the rod-shaped object supplying apparatus according to the second aspect, the uppermost movable guide member among the plurality of movable guide members rotates from the guide position to the retracted position. At this time, a reset means is provided for engaging the uppermost movable guide member to bring the claw members of the movable guide members other than the uppermost stage to the blocking release position.

According to a fourth aspect of the present invention, in the apparatus for supplying a rod-shaped object according to the third aspect, the reset means is moved when the uppermost movable guide member is rotated from the guide position to the retracted position. A driven lever that engages with the movable guide member and is rotationally displaced, and a driven lever that engages with the claw member of the movable guide member except the uppermost movable guide member to bring the claw member to the blocking release position. A lever,
And a link rod that is displaced by the rotational displacement of the drive lever to set the driven lever to the blocking release position.

[0011]

The round pipes, which are the main parts of the rollers, are inserted side by side into the shelf members of each stage. The inserted pipe rolls downward due to the inclination of the shelf member. A stopper member is arranged on the shelf member other than the lowermost stage, and the stopper member is biased so as to project in the movement path of the pipe,
It is in the locked position. Therefore, the pipes inserted in these shelf members do not reach the movable guide member,
A large number of pipes are stored in each shelf member.

Since the pipe inserted into the lowermost shelf member has no stopper member, it moves to the movable guide member and rotates the movable guide member to the guide position. At the guide position, since the pipe at the tip is positioned within the movement trajectory of the take-out member, the pipes are scooped one by one by the upward movement of the take-out member. When all the pipes are taken out from the lowest shelf member, the movable guides arranged on this shelf member rotate to the retracted position by their own weight. By this rotation, the stopper member of the immediately upper shelf member is pulled down by the interlocking means, and the stopper member is retracted from the pipe moving path of the shelf member and set to the unlocking position. As a result, the pipe is moved to the movable guide member and the weight of the pipe causes the movable guide member to be set from the retracted position to the guide position, and the shelf changing operation is automatically performed. Thereafter, in the same manner, each pipe is scooped by the take-out member from the shelf member, and when all the pipes are taken out from the shelf member,
The movable guide member rotates from the guide position to the retracted position by its own weight, and the stopper member immediately above is set to the unlocking position in conjunction with this rotation. Thereafter, in the same manner, the operation of changing the shelves is automatically performed in order from the bottom to the top, and one pipe is scooped by each take-out member from each shelf member.

In particular, in the rod-shaped object supply device according to the second aspect, the movable guide member is rotatably attached to the mounting shaft, and the claw member is rotatably provided on the movable guide member.
Further, the ratchet is fixed to the mounting shaft of the movable guide member. The claw member is moved between a blocking position that blocks rotation of the ratchet and a blocking release position where the ratchet is rotatable, and when the movable guide member is at the guide position, the claw member is moved to the blocking position by its own weight. I am trying to do it. Further, the rotational displacement of the mounting shaft of the movable guide member is transmitted to the stopper member via the displacement transmission portion including the wire wheel and the wire. Therefore, when the movable guide member rotates from the guide position to the retracted position by its own weight, the stopper member immediately above the movable guide member changes from the locked position to the unlocked position. As a result, the shelf changing operation can be easily performed automatically without the need for power or manual operation.

According to a third aspect of the present invention, there is provided a rod-shaped object supplying device.
When the uppermost movable guide member of the movable guide members rotates from the guide position to the retracted position, the uppermost movable guide member engages with the movable guide member other than the uppermost one of the pawl members of the ratchet. Since the resetting means for setting the rotation-releasable blocking release position is provided, when the movable guide member is moved from the guide position to the retracted position after all the pipes are taken out from the uppermost shelf member, the pawl member can rotate the ratchet. The blocking member is brought to the blocking release position, and the stopper member is returned to the locking position by the biasing means. Therefore, when all the pipes are taken out, the stopper member of each shelf member is automatically reset to the locking position, and a new pipe can be received.

According to another aspect of the present invention, there is provided a rod-shaped object supplying device.
When the uppermost movable guide member among the movable guide members rotates from the guide position to the retracted position, the drive lever engaged with this is pushed down. The link rod is lifted by the displacement caused by the depression of the drive lever, and the driven lever is displaced in conjunction with this, and the locking between the pawl member of the movable guide member and the ratchet is released. In this way, the drive lever,
By moving the uppermost movable guide using the link rod and the driven lever, the pawl member can be brought to the blocking release position where the ratchet can rotate, so that the stopper member can be reliably reset.

After being inserted and fixed, and the process of measuring the length of the roller, the roller is assembled. The assembled rollers are discharged to the roller storage device 14 via the discharge conveyor 16, and are sequentially stored in each shelf here.

In the pipe supply device 11, five levels of shelf rails 20 are arranged so as to be inclined with respect to the machine frame 21. The shelf rails 20 are respectively arranged near both side plates 21a of the machine frame 21, and even if the pipe 15 is obliquely inserted between the pair of shelf rails 20, pipes are inserted from the gap between the shelf rails 20. In order to prevent 15 from falling off, auxiliary rails (not shown) are arranged at an appropriate pitch. The inclination angle of the shelf rail 20 and the auxiliary rail is set to 5 degrees with respect to the horizontal direction so that the pipe 15 can move smoothly.

As shown in FIGS. 1 and 3, each shelf rail 2
A movable guide 25 is rotatably attached to a mounting shaft 26 via a bearing 27 in the vicinity of the lower end of 0. The movable guide 25 is erected at a retracted position and a guide position inclined by about 1/4 rotation from the retracted position. It is supposed to change between and. The mounting shaft 26 is horizontally mounted on the machine frame 21 via a pillow block 28.

As shown in FIG. 1, the movable guide 25 is composed of a rectangular metal thick plate with rounded corners. A mounting hole 33, through which the mounting shaft 26 penetrates, is formed in the movable guide 25 at a position decentered from the center of gravity. Further, one side edge serves as a guide surface 25a of the pipe 15, and when the pipe 15 moves from the shelf rail 20, the movable guide 25 rotates about a quarter around the mounting shaft 26 due to its own weight. This guide surface 25
The guide position a is an upwardly inclined state. At this guide position, the guide surface 25a and the upper surface 20a of the shelf rail 20 are flush with each other.
Can smoothly transfer from the shelf rail 20 to the movable guide 25.

As shown in FIG. 4, a stopper rod 35 is horizontally attached to the shelf rail 20, and the stopper rod 35 abuts the movable guide 25 so that the movable guide 25 rotates about 1/4. After reaching the guide position, further rotation is prevented. A locking projection 36 is formed on the tip of the guide surface 25a of the movable guide 25. The locking projection 36 is provided with an arcuate receiving surface 36a and prevents the pipe 15 from falling off the movable guide 25.

The mounting shaft 26 of the movable guide 25 has a
A ratchet 37 is fixed between the pillow block 28 (see FIG. 3) and the movable guide 25. Further, a claw member 38 that engages with the ratchet 37 is rotatably attached to the movable guide 25 via an attachment shaft 39. Also,
A wire wheel 40 is fixed to a mounting shaft 26 of the movable guide 25, and is configured to rotate integrally with a ratchet 37. One end of a wire 41 is fixed to the wire wheel 40. The wire 41 is guided by the guide wheel 42 to the pipe stopper 45 at the stage immediately above, and the other end of the wire 41 is fixed to the lower end portion of the stopper pin 47 of the pipe stopper 45. FIG.
As shown in FIG. 3, since the shelf rail 20, the movable guide 25, and the pipe stopper 45 are not arranged in the upper stage of the mounting shaft 26 of the uppermost stage, the pipe stopper 45 of the upper stage is controlled. Ratchet 37 and claw member 3 for
8. The wire wheel 40 is not provided.

The pipe stopper 45 is arranged close to the lower ends of the shelf rails 20 other than the lowest stage. FIG.
As shown in FIG.
And a stopper pin 47 with a flange 47a, and a coil spring 48. The stopper pin 47 is biased upward by a coil spring 48 via a flange 47a, so that the upper end of the stopper pin 47 projects into the pipe movement path of the shelf rail 20.
It is the locking position of the pipe 15. In addition, the stopper pin 47
The wire 41 is fixed to the lower end of the stopper pin 4 and the stopper pin 4
The upper end of 7 is housed in the case body 46, and the pipe 15
Is the unlocked position.

In this way, the stopper pin 47 and the wire wheel 40 are interlocked with each other, and the movable guide 2 is formed by the engagement of the claw member 38 and the ratchet 37.
Only when 5 is rotationally displaced from the guide position to the retracted position,
Since the movable guide 25 and the mounting shaft 26 rotate integrally, the shelf changing operation can be automatically performed.
That is, as shown in FIG. 5, when all the pipes 15 on the movable guide 25 are taken out and become empty, the movable guide 25
Rotates by its own weight in the clockwise direction in the figure. Due to this rotation shift, the pipe stopper 45 on the immediately upper stage changes from the locked position to the unlocked position. Therefore, the pipe 15 on the shelf rail 20 moves onto the movable guide 25, and the movable guide 25 becomes the guide position due to the weight of the pipe 15, and the shelf changing operation is completed. Further, when the movable guide 25 is rotationally displaced to the guide position, the pawl member 38 does not engage with the ratchet 37, so that the pipe stopper 45 immediately above does not operate.

As shown in FIG. 1, the uppermost movable guide 2
5 and the claw members 38 of the movable guide 25 at each stage except the uppermost stage
A drive lever 50 and a driven lever 51 are engaged with and the levers 50 and 51 are interlocked via a link rod 52, and an interlocking means 49 is configured. The drive lever 50 and the driven lever 51 are
It is rotatably attached to the machine frame 21 via an attachment shaft 53. Therefore, as shown in FIG. 6 (A), the uppermost movable guide 25 moves from the guide position to the state shown in FIG. 6 (B).
As shown in (4), when all the pipes 15 have been taken out and moved to the retracted position, the drive lever 50 engaging with this rotates clockwise to lift the link rod 52 upward. As a result, each driven lever 51 rotates in the clockwise direction and sets each claw member 38 to the blocking release position for releasing the blocking of the rotation of each ratchet 37. Therefore, the engagement between the claw member 38 and the ratchet 37 is released, so that the stopper pin 47 is released.
Is brought to the pipe locking position by the urging force of the coil spring 48 (see FIG. 4) and is returned to the initial state. by this,
Even if the pipes 15 are stored in the empty shelf rails 20 of each stage, as shown in FIG. 7C, only the lowermost movable guide 25 without the pipe stopper 45 is in the guide position, and the other stages are Since the pipe 15 is stopped by the pipe stopper 45, the movable guide 25 is in the retracted position.

As shown in FIG. 1, the take-out member 60 is attached to the endless chain 61 at a predetermined pitch, and the take-out member 60, the endless chain 61, and a motor (not shown) for rotating the endless chain 61 take out the take-out member 60. The conveyor 62 is configured. Then, by the upward movement of the take-out member 60, only the pipe 15 set at the take-out position which is the tip of the movable guide 25 at the guide position is picked up and sent to the conveyor 12 in the next step shown in FIG. As shown in FIG. 4, when the pipe 15 at the take-out position is scooped by the take-out member 60 on the movable guide 25, the next pipe 15 moves to the take-out position by its own weight. Therefore, one pipe after another
5 is scooped out of the movable guide 25 by the take-out member 60,
It is sent to the conveyor 12 in the next step.

As shown in FIG. 5, the take-out member 60 is formed in a U shape, and the lower first horizontal plate 63 is projected longer than the upper second horizontal plate 64. Therefore,
When the take-out member 60 moves upward, the first horizontal plate 6
Only the pipe 15 in the take-out position is scooped by 3, so that it is housed in the take-out member 60. Locking protrusions 63a and 64a are formed at the tips of the horizontal plates 63 and 64 so as to project inward, so that the pipe 15 does not drop out of the take-out member 60.
Further, as shown in FIG. 1, when the endless chain 61 rotates and the take-out member 60 becomes the conveyor 12 side, the pipe 15 rolls in the take-out member 60 and the second horizontal plate 64 becomes the lower side. 2 The pipe 15 is conveyed while being mounted on the horizontal plate 64. A plurality of guide plates 65 are arranged at the connection positions of the take-out conveyor 62 and the conveyor 12, and the guide members 65 are moved by the take-out member 60 moving downward.
Thus, the pipe 15 in the take-out member 60 is scooped and sent to the pipe holding portion 66 of the conveyor 12.

Next, the operation of this embodiment will be described. Figure 6
As shown in (B), in the empty state, the movable guides 2 of each stage are
5 is set to a retracted position in which it stands up by its own weight. Further, the pipe stopper 45 is in a locking position where the stopper pin 47 is projected in the pipe movement path. In this state, as shown in FIG. 7C, a large number of pipes 15 are housed in each shelf rail 20. Each pipe 15 rolls on the shelf rail 20 by its own weight and moves downward.

As shown in FIG. 7C, since the lowermost shelf rail 20 does not have the stopper pin 47, the movable guide 25 is moved from the retracted position to the guide position due to the weight of the pipe 15, and the pipe 15 is moved to the movable guide 25. Guide surface 25a
The pipes are lined up to the take-out position of the upper pipe 15. Further, in the other shelf rails 20, the stopper pins 47 are in the locking position and the pipes 15 are stopped, and the pipes 15 are stored side by side in the respective shelf rails 20.

As shown in FIG. 1, when the take-out conveyor 62 rotates and the take-out member 60 moves upward, only the pipe 15 at the take-out position of the movable guide 25 is picked up by the take-out member 60, which is the conveyor. Sequentially sent to 12. When all the pipes 15 are taken out from the lowermost movable guide 25, the movable guide 25 rotates from the guide position to the retracted position by its own weight as shown in FIG. At this time, since the claw member 38 attached to the movable guide 25 via the attachment shaft 39 is in a state of preventing the ratchet 37 from rotating due to its own weight, the movable guide 25 is attached via the ratchet 37 due to the rotational displacement. The shaft 26 rotates. This allows the wire wheel 40
Also rotates clockwise and the wire 41 is wound up, and the stopper pin 47 of the pipe stopper 45 immediately above moves from the locked position to the unlocked position. Therefore, the pipe 15 moves to the movable guide 25 side by its own weight, and the movable guide 25
Moves from the retracted position to the guide position. In this way, the shelf changing operation is performed, and in the same manner, the movable guides 25 of the shelf rails 20 are sequentially set from the bottom to the top at the guide positions.
The pipes 15 are sequentially taken out from the shelf rails 20 of each stage.

When all the pipes 15 are taken out from the state shown in FIG. 6A and the state shown in FIG. 6B is reached, the uppermost movable guide 25 moves from its guide position (see FIG. 6A) by its own weight. It becomes the retracted position. Due to this rotation shift, the drive lever 50 is pushed down, the driven lever 51 shifts via the link rod 52, and the pawl member 38 is set to the blocking release position for canceling the blocking of the rotation of the ratchet 37. As a result, the engagement between the ratchet 37 and the claw member 38 is released, and the stopper pin 47 is set at the engagement position by the biasing force of the coil spring 48 (see FIG. 4).

In the above embodiment, the shelf member is composed of the shelf rail 20 and the auxiliary rail, but instead of this, a shelf plate may be used as the shelf member. Moreover, the number of steps of the shelf member is 5.
The number of stages is not limited to stages, and may be increased or decreased as appropriate according to the processing capacity of the roller manufacturing machine 13, and preferably the number of stages corresponds to the number of pipes accommodated according to the processing capacity of the roller manufacturing machine 13 per day.

Further, in the above embodiment, the present invention is applied to the pipe supply device 11 which accommodates the round pipe 15 which is a main part of the roller and supplies the round pipes one by one. The present invention may be applied to pipes and a large number of rods each having a round or square cross section and supplied one by one. Furthermore, although the inclination angle of the shelf rail 20 is set to 5 degrees, it is preferable to change this inclination angle as appropriate depending on the pipe or rod to be stored. For example, in the case of a pipe or a rod having a polygonal cross section, since it moves on the shelf rail 20 by a sliding motion, the movement resistance increases, so the inclination angle is increased. Further, in the case of a rod having a circular cross section, the weight increases as compared with a round pipe, so that the locking projection 3 of the movable guide 25
The inclination angle is made small so that the pipe 15 does not fall off after riding over 6.

Further, in the above embodiment, the interlocking means 49 is provided, and the movable guides 25 at the uppermost stage are rotated and moved from the guide position to the retracted position after the pipe is taken out. Although the rotation blocking of the ratchet 37 by the claw member 38 is released, a manual blocking releasing means may be provided instead. In this case, instead of engaging the drive lever 50 of the interlocking means 49 with the uppermost movable guide 25, the drive lever 50 may be used as an operating lever and manually pushed down. This lifts the link rod 52 upwards,
The rotation prevention of the ratchet 37 by each claw member 38 is released, and the pipe stopper 45 is set from the unlocked position to the locked position.

Further, in the above embodiment, the wire 41 and the guide wheel 42 constitute the displacement transmitting portion, but in addition to this, the ratchet 37 and the pipe stopper 45 may be linked by a link mechanism or a gear train. Further, in the above-described embodiment, the stopper pin 47 slides in and out of the pipe moving path, but in addition to this, the locking member may be moved in and out of the pipe moving path by the swinging motion. .

According to the invention described in claim 1, the movable guides are arranged in the vicinity of the lower end portions of the respective shelf members, and the movable guides are retracted from their respective shelving positions where the movable guides are in an upright state by their own weight. The rod-shaped object is rotated and displaced between the guide position where the rod-shaped object is rotated and tilted by the movement of the rod-shaped object. Since the locking member is provided so that it does not exist, it is possible to selectively take out the rod-shaped object from each shelf member by the movable guide in the supply device including a plurality of stages of shelf members.

Further, a stopper member is provided at the lower end portion or in the vicinity of the lower end portion of the other shelf members except the lowermost shelf member, and the stopper member is provided between the locking position and the locking releasing position of the rod-shaped object. Since the stopper member is biased toward the locking position, the stopper member will lock the object even if a rod-shaped object is inserted into the other shelf members except for the lowermost stage. It does not move to the member.

Further, the movable guide member and the stopper member immediately above the shelf member on which the movable guide member is provided are interlocked with each other, and the stopper member is operated by utilizing the transition of the movable guide member from the guide position to the retracted position. Therefore, when the lower rod-shaped object is taken out and becomes empty, the stopper member of the upper shelf member is automatically set to the unlocked position, and the rod-shaped object on the upper shelf member can be taken out. Therefore, it is possible to automatically change the shelves by simplifying the configuration without using power or manpower.

The interlocking means is composed of a ratchet fixed to the mounting shaft of the movable guide member, a claw member provided on the movable guide member, and a displacement transmission unit that operates the stopper member by rotational displacement of the ratchet, and the movable guide member is a guide. Since the pawl member is configured to rotate together with the movable guide member in the blocking position where the rotation of the ratchet is blocked when rotating from the position to the retracted position, the rotation shift of the movable guide member is used to make it higher than the movable guide member. The stopper member can be reliably set to the unlocked position.

According to the invention described in claim 3,
When the uppermost movable guide member rotates from the guide position to the retracted position, it engages with the movable guide member, and the claw members of each movable guide member except the uppermost stage are moved to the blocking release position where the ratchet can rotate. Since the reset means is configured so that after all the pipes are taken out, the stopper member of each shelf member is automatically reset to the locking position by the urging force, and the pipes can be received.

According to the invention described in claim 4,
When the uppermost movable guide member rotates the reset means from the guide position to the retracted position, the drive lever engages with the movable guide member and rotationally shifts, and each movable guide member except the uppermost movable guide member. Of the driven lever that engages with the claw member of (1) to bring the claw member to the blocking release position where the ratchet can rotate, and the link rod that shifts due to rotational displacement of the drive lever to set the driven lever to the blocking release position. With this configuration, when all the rod-shaped objects are taken out from the uppermost movable guide member and the movable guide member rotates from the guide position to the retracted position by its own weight, the claw members of each movable guide member prevent the ratchet from rotating. It is moved from the position to the blocking release position. Therefore, the stopper member can be surely reset without power or manual operation, and the rod-shaped object can be received.
