CONSTITUTION:When taking out an empty storage holder 11 at the top with a supporting force from below using a support device 34, a bead B with filler deposited on the second-stage storage holder 11 is pressed against the storage holder 11 using holding claws which can move in a radial direction where a spring 51 is energized.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] This invention is for use with filler beads, in which the top storage holder from which filler beads have been removed is taken out one after another from a pile stacked in multiple stages with filler beads placed on storage holders. The present invention relates to a storage holder removal device.

0002

BACKGROUND OF THE INVENTION The present applicant has already proposed a take-out device for highly efficient take-out of the uppermost storage holder from which filler beads have been removed from the above-mentioned pile in Japanese Patent Application No. 1-245.
This is proposed in Specification No. 580 (filed on September 21, 1999).

[0003] This device is movable up and down above the mountain of the storage holder and filler beads, and has three guide rods extending vertically so as to guide the storage holder from the outside in the radial direction, and each guide rod. a claw that is swingably supported at the lower end and can come into contact with the lower surface of the lower end of the storage holder when it swings so as to protrude radially inward; and a claw that is attached to each guide rod;
A cylinder for swinging the claw. In this case, when the bead with filler is removed from the uppermost storage holder, the guide rod is lowered to lower the claw to a position slightly below the lower end of the uppermost storage holder. Next, each cylinder is actuated to swing the claws so as to protrude radially inward, causing some of these claws to enter below the uppermost storage holder. Next, when the guide rod is raised, the uppermost storage holder is supported from below by the claws and is raised together with the guide rod, and is removed from the mountain.

0004

[Problem to be Solved by the Invention] However, in such a device for taking out a storage holder for beads with filler, it is difficult to remove the beads with filler placed on the storage holder in the second stage located directly below the top stage. If the filler bead is deformed and a part of it sticks to the uppermost storage holder, there is a risk that the filled bead will be taken out together with the uppermost storage holder.

[0005] This invention makes it possible to reliably separate and take out only the empty storage holder at the top level from the filler bead even if a part of the filler bead immediately below is stuck. An object of the present invention is to provide a device for taking out a storage holder for beads with filler.

[0006]

[Means for Solving the Problem] This purpose is to attach a bead with a filler to a storage holder that has a truncated conical shape that widens toward the bottom and has a truncated conical through hole that penetrates vertically inside the holder. A device for taking out a storage holder for filled beads, which sequentially takes out the storage holder in the uppermost stage from which beads with filler have been removed from a pile stacked in multiple stages in a loaded state, the device being relatively close to the pile. a frame that can be separated; a support means that is attached to the frame and that can enter the underside of the storage holder; and a support means that can support the storage holder from below when it enters the underside of the storage holder; a stopper provided at the lower end of the frame for determining the lowering limit of the elevating object; a spring that biases the elevating object downward; a plurality of presser claws that can pass through the through holes of the storage holder when moved radially inward, and that can come into contact with filler-equipped beads placed on the storage holder when moved radially outward;
This can be achieved by including a moving mechanism that moves these presser claws in the radial direction in synchronization.

[0007]

[Operation] Now, assume that beads with filler are placed on the storage holder to form a multi-level pile. In this state, the filled beads are removed from the uppermost storage holder to empty the uppermost storage holder. Next, the frame and the mountain are brought relatively close to each other, and the elevating body is caused to enter the through hole of the uppermost storage holder. and,
When the presser claw supported by the elevating body reaches a position slightly above the filler-equipped bead placed on the second storage holder located directly below the uppermost stage, the approaching operation is stopped. Next, the plurality of presser claws are moved radially outward in synchronization by the moving mechanism. Next, when the frame and the peak are brought relatively close again, the presser claw is pressed against the filler bead placed on the second storage holder, and even when pressed in this way, the frame and Bring the mountains closer together. As a result, the presser pawl and the elevating body rise relative to the frame, the spring is deformed, and elastic force is stored in the spring. Then, the elastic force of this spring is applied as a force to the presser claw, and the filler-equipped bead is strongly pressed against the second-stage storage holder. Then, when the support means reaches the support position, the approaching operation is stopped. Next, the support means is inserted into the lower side of the uppermost storage holder. Next, when the frame and the mountain are relatively separated, the empty storage holder on the uppermost stage is taken out from the mountain while being supported from below by the support means. At this time, as mentioned above, the bead with filler is pressed against the second storage holder by the presser claw that receives the biasing force of the spring, so the bead with filler is deformed and a part of the bead with filler is pressed against the storage holder on the top stage. Even if the filler beads are sticky, the uppermost storage holder is reliably separated from the filler beads, and the filler beads are not taken out together. When the elevating body descends to the lower limit and contacts the stopper, the elevating body becomes integral with the frame and separates from the mountain.

[0008] Furthermore, with the configuration as described in claim 2, each support claw can be moved over a wide range in the radial direction, so even if the mountain is inclined diagonally, the entire support claw can be moved over a wide range in the radial direction. The uppermost storage holder can be supported from below by the support claws, ensuring reliable removal.

[0009]Furthermore, with the configuration as set forth in claim 3, it is possible to easily take out a plurality of types of storage holders of different sizes.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 11 is a filler bead B
This storage holder 11 stores
is molded from highly rigid resin. Each storage holder 11 has a truncated cone shape that widens toward the bottom, and a through hole 12 that penetrates vertically and has a truncated cone shape that widens toward the bottom is formed inside the storage holder 11 . In addition, each storage holder 1
1 has a truncated conical inclined part 13, and this inclined part 13
has a constant thickness regardless of its axial position, and does not deform even if subjected to some external force. Reference numeral 14 denotes a placing portion that is continuous with the upper end of the inclined portion 13;
It has a ring shape extending radially inward from the upper end, and its inner diameter (minimum inner diameter of the storage holder 11) is the same as shown by the imaginary line even if the sizes are different. Reference numeral 15 denotes a substantially cylindrical support portion extending upward from the lower end of the inclined portion 13, and the axial distance of this support portion 15 is equal to the bead C.
greater than the width of As a result, when the storage holders 11 are stacked upward one after another with the lower end of the support part 15 in contact with the upper end of the support part 15, a space 16 is formed between adjacent storage holders 11. And each storage holder 1
Bead B with filler stored in 1, that is, the mounting part 14
The bead C placed above and the filler F arranged so as to surround the outside of the inclined portion 13 are located within this space 16 . Further, a flange 17 is provided on the outer periphery of the lower end portion of the support portion 15 and protrudes toward the outside in the radial direction. These storage holders 11 are stacked in multiple stages on a mounting table (not shown) which can be raised and lowered with filler-equipped beads B placed thereon, thereby forming a mountain 18.

An elevating plate 20 that is raised and lowered by a cylinder or the like (not shown) is arranged above the mountain 18, and the lower surface of this elevating plate 20 has an elevating plate 20 that is coaxial with the axis of the storage holder 11 that forms the mountain 18. The shaft 21 is fixed. The above-mentioned lifting plate 20 and lifting shaft 21 collectively constitute a frame 22 that can move toward and away from the mountain 18.

As shown in FIGS. 1, 2, and 3, a horizontal substantially triangular plate-shaped support 23 is fixed to the lower end of the lifting shaft 21, more specifically, above the lifting body 37, which will be described later. This support body 23 has a plurality of pairs (here, 3 pairs) spaced apart at equal angles.
A pair of rollers 24 are rotatably supported. Reference numeral 25 denotes a horizontal disc cam coaxial with the lifting shaft 21 and provided directly above the support body 23. The roller 24 rolls into contact with the outer periphery of this disc cam 25, so that the disc cam 25
is rotatably supported by rollers 24. This disk cam 2
5 is formed with a plurality of (three in this case) cam grooves 26 that are inclined in the same direction with respect to the radial direction and extend linearly, and the upper end of the transmission member 27 is inserted into each of these cam grooves 26. There is. Three pairs of guide blocks 28 are attached to the lower surface of the support body 23 at equal angles apart, and support claws 29 extending in the radial direction are supported on each pair of guide blocks 28 so as to be movable in the radial direction. 30
are radially extending cam grooves formed in the support body 23 directly below the transmission member 27, and these cam grooves 30 have the transmission member 27 fixed to the support claw 29.
The center part of is inserted. As a result, the disc cam 2
5 rotates, the support claws 29 are moved in the radial direction by the cam grooves 26, 30 and the transmission member 27. When these support claws 29 move radially inward, they can also pass through the smallest diameter part of the through hole 12 of the storage holder 11, while when they move radially outward, they can pass through the upper end of the through hole 12. The lower surface, more specifically, the lower surface of the mounting portion 14 can be contacted. 31 is a multistage cylinder whose head side is supported by the shaft of one of the rollers 24, and the tip of the piston rod 32 of this cylinder 31 is connected to the disc cam 25. As a result, when the cylinder 31 operates, the disc cam 25 rotates. The aforementioned disc cam 25 and transmission member 27
, the cylinder 31 as a whole constitutes a drive mechanism 33 for synchronously moving the support claws 29 in the radial direction, and the support body 23, the support claws 29, and the drive mechanism 33 as a whole:
A support means 34 is configured that can support the storage holder 11 from below when the storage holder 11 enters the lower side thereof.

In FIGS. 1, 4, and 5, a sleeve 36 is slidably fitted on the lifting shaft 21 below the support 23, and a lifting body 37 similar to the support 23 is attached to the sleeve 36. attached. As a result, the elevating body 37 and the sleeve 36 can be moved up and down relative to the frame 22, specifically, the elevating shaft 21. This elevating body 37
Similarly to the above, a plurality of pairs of rollers 38 are rotatably supported. 39 is a disc cam provided directly below the elevating body 37, and this disc cam 39 is rotatably supported by the roller 38. Cam grooves 40 similar to the cam grooves 26 are formed in this disc cam 39, and transmission members 41 are inserted into each of these cam grooves 40. A plurality of pairs of guide blocks 42 are attached to the upper surface of the elevating body 37, and a plurality of presser claws 43, which are offset in the circumferential direction with respect to the support claws 29, are movable in the radial direction on these pairs of guide blocks 42. Possibly supported. Reference numeral 44 denotes radially extending cam grooves formed in the elevating body 37, into which the central portion of the transmission member 41 fixed to the presser pawl 43 is inserted. When these presser claws 43 move radially inward, they can also pass through the smallest diameter part of the through hole 12 of the storage holder 11, while when they move radially outward,
The bead B with filler placed on the placing part 14 of the storage holder 11 can be contacted and pressed from above. 45 is a multistage cylinder whose head side is supported by the shaft of one of the rollers 38, and the tip of the piston rod 46 of this cylinder 45 is connected to the disk cam 39. As a result, when the cylinder 45 operates, the disk cam 39 rotates and the presser claws 43 move in the radial direction. The aforementioned disc cam 39, transmission member 41, cylinder 4
5 as a whole constitutes a moving mechanism 47 that moves the presser claws 43 in the radial direction in synchronization. A spring 51 is interposed between the sleeve 36 and a step 50 formed on the elevating shaft 21 above the elevating member 37, and urges the elevating member 37 downward, that is, toward the peak 18. A ring-shaped stopper 52 is fixed to the lower end of the elevating shaft 21, and this stopper 52 comes into contact with the sleeve 36 to determine the lowering limit of the elevating member 37 when the elevating member 37 descends to its lower limit. Further, a plurality (three in this case) of arc-shaped guide bodies 53 are fixed to the outer end in the radial direction of the elevating body 37 at equal angles apart, and each guide body 53 extends in the vertical direction. Then, from the axis of the lifting shaft 21, each guide body 5
The distance to the outer surface of the upper end of the storage holder 11 is approximately equal to half the inner diameter of the mounting portion 14 in the storage holder 11, that is, the minimum radius of the through hole 12. Further, the outer surface of the lower end of each guide body 53 is inclined so as to approach the inner side in the radial direction as it goes downward.
Overall, it is tapering off. As a result, even if the top storage holder 11 is displaced from its normal position due to the slope of the mountain 18 due to the removal of the filler-attached bead B, for example, when the elevating body 37 descends, the guide body 53 The storage holder 11 can be easily inserted into the through hole 12 of the storage holder 11, and the storage holder 11 on the uppermost stage can be centered and returned to the normal takeout position. The aforementioned elevating body 3
7. The presser claw 43, the moving mechanism 47, the spring 51, the stopper 52, and the guide body 53 as a whole, when taking out the uppermost empty storage holder 11, the second storage holder 11 located directly below the uppermost storage holder 11. A separating means 54 is configured to press the filler-equipped bead B placed on the storage holder 11 on the second stage and reliably separate it from the storage holder 11 on the uppermost stage.

Again, in FIG. 1, reference numeral 57 denotes a plurality of arms (three in this case) whose base ends are fixed to the lifting shaft 21 above the support 23, and these arms 57 extend in the radial direction. . A guide 58 having an arcuate cross section extending in the vertical direction is integrally formed at the tip of each arm 57. The distance from the axis of the lift shaft 21 to the outer surface of the upper end of each guide 58 is approximately equal to half the inner diameter of the mounting portion 14 in the storage holder 11, that is, the minimum radius of the through hole 12. Also,
The outer surface of the lower end of each guide 58 is inclined toward the inner side in the radial direction as it goes downward, and is tapered as a whole. As a result, when the storage holders 11 taken out from the piles 18 are fitted on the outside of these guides 58, these storage holders 11 are centered by the guides 58, and the piles of empty storage holders 11 are prevented from tilting. Ru.

Next, the operation of one embodiment of the present invention will be explained. It is now assumed that a plurality of storage holders 11 in which filler-equipped beads B are placed on the placing portions 14 are stacked in multiple stages to form a mountain 18, and that this mountain 18 is placed on the placing table. At this time, the frame 22 has risen and stopped, and the empty storage holders 11 centered by the guides 58 are stacked and placed on the support claws 29 that are moving radially outward. In this state, a bead removal device (not shown) removes the filled beads B from the uppermost storage holder 11, thereby emptying the uppermost storage holder 11. Next, the frame 22, the support claw 29, the guide body 5
3 and the empty storage holder 11 etc. supported by the support claws 29 are lowered to approach the mountain 18, and the separation means 54 is inserted into the through hole 12 of the storage holder 11 at the uppermost stage. At this time, by taking out the bead B with filler, the mountain 1
8 is tilted and the uppermost storage holder 11 is deviated from its normal position, the guide body 53 moves the uppermost storage holder 11
By being inserted into the through hole 12, the uppermost storage holder 11 is centered and returned to the normal take-out position. Further, at this time, since the presser claws 43 of the separating means 54 have moved inward in the radial direction, the presser claws 43 do not come into contact with the mounting portion 14 of the storage holder 11. When the presser claw 43 of the separating means 54 reaches a position slightly above the filler-equipped bead B placed on the second storage holder 11 located directly below the uppermost stage, the frame 22 is lowered (the peak 18 approach). At this time, the empty storage holder 11 supported by the support claws 29 is transferred onto the uppermost storage holder 11.

Next, the piston rod 46 of the cylinder 45
is projected, and the disc cam 39 is rotated in the forward direction. As a result, the plurality of presser claws 43 move radially outward in synchronization,
The tips of these presser claws 43 are the second stage storage holder 11
The bead B with filler is placed directly above the filler bead B. Next, the piston rod 32 of the cylinder 31 is retracted, the disk cam 25 is reversely rotated, and the support claws 29 are synchronously moved radially inward. As a result, these support claws 29 are separated from the empty storage holder 11 that they have supported up to now. Next, the mounting table and the mountain 18 are raised by one pitch, that is, the same distance as the height of the support part 15, so that the mountain 18 approaches the frame 22. While the mountain 18 is rising, the filler-equipped bead B placed on the second storage holder 11 is pressed against the tip of the presser claw 43 from below. Since the peak 18 further rises with the filler-attached bead B being pressed against the presser claw 43 in this manner, the presser claw 43 and the elevating body 37 rise with respect to the frame 22. As a result, the spring 51 is compressed and deformed, and elastic force is stored in the spring 51. Then, the elastic force stored in the spring 51 is applied as a force to the presser pawl 43, and the filler-equipped bead B is strongly pressed against the second stage storage holder 11 by the presser pawl 43. Also, at this time, the support means 34
enters into the through hole 12 of the uppermost storage holder 11. Then, when the mountain 18 rises by one pitch, the support claw 29 of the support means 34 moves the filler placed in the second storage holder 11 below the placement part 14 of the top storage holder 11. The support position is reached above the attached bead B. Next, the piston rod 32 of the cylinder 31 of the support means 34 is made to protrude and the disc cam 25 is rotated in the forward direction. As a result, the support claws 29 synchronously move outward in the radial direction, and the tips of these support claws 29 enter the lower side of the placement section 14 of the uppermost storage holder 11. By moving the support claws 29 in the radial direction in this way, each support claw 29 can be moved over a wide range in the radial direction. Even in this case, the tips of all the support claws 29 can be moved below the placement part 14 of the uppermost storage holder 11,
The storage holder 11 can be taken out reliably.

Next, the frame 22 is raised, and the frame 22 and the support means 34 are separated from the mountain 18. At this time, the support claw 29 is attached to the mounting portion 1 of the uppermost storage holder 11.
4, the empty uppermost storage holder 11 is taken out from the pile 18 while being supported from below by the support claws 29. At this time, since the filler bead B is pressed against the second storage holder 11 by the presser claw 43 which receives the biasing force of the spring 51 as described above, the filler bead B is deformed and the filler bead B is deformed to the uppermost stage. Even if a part of the storage holder 11 is stuck, the uppermost storage holder 11 is reliably separated from the filler-equipped bead B, and the filler-equipped bead B is not taken out together with the storage holder 11. Also,
At this time, since the elevating body 37 and the presser pawl 43 are urged downward by the spring 51, they stop at a fixed position regardless of the rise of the frame 22, and as a result, the frame 22
For 2, it will go down. The elevating body 37 and the like descend to the lower limit where the sleeve 36 abuts the stopper 52, and then separate from the mountain 18 together with the frame 22. The storage holder 11 taken out from the pile 18 in this manner becomes the lowest stage of the storage holders 11 stacked on the support claws 29. and,
As the frame 22 rises, the ridges of these empty storage holders 11 are fitted to the outside of the guide 58, and are centered and prevented from tilting. Next, when the frame 22 returns to the initial position, the piston rod 46 of the cylinder 45
is retracted, and the presser pawl 43 moves radially inward in synchronization. The above is one cycle of the operation of one embodiment of the present invention, and this cycle is repeated thereafter, and the storage holder 1
1 is taken out one after another. In addition, if there is a change in the size of the storage holder 11 or bead B with filler,
Piston rods 32 and 4 of the multi-stage cylinders 31 and 45
To deal with this problem, change the stroke in step 6.

In the above embodiment, the cylinders 31 and 4 are used to take out storage holders of different sizes.
Although 5 is a multi-stage cylinder, in the present invention, the disc cam may be rotated by the required amount by an electric motor, a rotary actuator, or the like.

[0019]

[Effects of the Invention] As explained above, according to the present invention, even if a part of the bead with filler directly below is sticky, only the empty storage holder at the top level can be connected to the bead with filler. It can be reliably separated and taken out.
