Field of the Invention The present invention relates to a bead with a filler for sequentially taking out the uppermost storage holder from which a bead with a filler has been removed from a plurality of stacked piles in a state where beads with a filler are placed on the storage holder. The present invention relates to a storage holder removal device.

[0002]

2. Description of the Related Art The present applicant has already disclosed a take-out device for taking out the uppermost storage holder from which a bead with a filler has been removed from a mountain as described above in Japanese Patent Application No. Hei 1-245.
No. 580 (filed on September 21, 1999).

[0003] This is provided so as to be able to move up and down above the mountain of the storage holder and the bead with filler, and three guide rods extending vertically so as to guide the storage holder from the outside in the radial direction; The lower end is swingably supported, and when swinging so as to protrude inward in the radial direction, a claw capable of contacting the lower surface of the lower end of the storage holder, and attached to each guide rod,
And a cylinder for swinging the claw.
Then, when the bead with filler is removed from the uppermost storage holder, the guide rod is lowered to lower the pawl slightly below the lower end of the uppermost storage holder. Next, each cylinder is operated to swing the claws so as to protrude inward in the radial direction, and a part of these claws is made to enter below the uppermost storage holder. Next, when the guide rod is raised, the uppermost storage holder is raised together with the guide rod while being supported from below by the claw, and is removed from the mountain.

[0004]

However, in such an apparatus for taking out a storage holder for a bead with a filler, a bead with a filler placed in a second-stage storage holder located immediately below the uppermost stage. When a part of the bead is deformed and sticks to the uppermost storage holder, the bead with filler may be taken out together with the uppermost storage holder.

[0005] According to the present invention, even when a part of the bead with the filler at the lower stage is sticky, only the empty storage holder at the uppermost stage can be reliably separated and taken out from the bead with the filler. An object of the present invention is to provide a takeout device for a bead storage holder with a filler.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a bead with a filler in a storage holder having a truncated conical shape diverging downward and having a truncated conical through hole formed therein. A storage device for a bead storage holder with a filler that sequentially removes the uppermost storage holder from which a bead with a filler has been removed from a plurality of stacked piles in a mounted state, and is relatively close to the mountain. A frame that can be separated, supporting means attached to the frame, which can enter the lower side of the storage holder, and which can support the storage holder from below when entering the lower side of the storage holder; A lifting / lowering body movably supported, a stopper provided at a lower end of the frame to determine a descent limit of the lifting / lowering body, and a split for urging the lifting / lowering body downward And is supported by the elevating body so as to be movable in the radial direction, can pass through the through hole of the storage holder when moved inward in the radial direction, and is placed on the storage holder when moved outward in the radial direction. A plurality of pressing claws capable of contacting a bead with a filler,
A moving mechanism for synchronously moving these presser claws in the radial direction.

[0007]

Now, it is assumed that a plurality of stacked piles are formed with the beads with filler placed on the storage holder. In this state, the beads with filler are removed from the uppermost storage holder, and the uppermost storage holder is emptied. Next, the frame and the mountain are relatively approached to each other, and the elevating body is caused to enter the through hole of the uppermost storage holder. Then, when the pressing claw supported by the elevating body reaches slightly above the bead with the filler placed in the second-stage storage holder located immediately below the uppermost stage, the approaching operation is stopped. Next, the plurality of pressing claws are synchronously moved outward in the radial direction by the moving mechanism. Next, when the frame and the mountain relatively approach each other again, the pressing claw is pressed against the bead with the filler placed on the second-stage storage holder. Get closer to the mountains. As a result, the presser pawls and the elevating body rise with respect to the frame, the spring is deformed, and the elastic force is stored in the spring. Then, the elastic force of the spring is applied to the pressing claw as an urging force, and the bead with the filler is strongly pressed against the second-stage storage holder. When the support means reaches the support position, the approach operation is stopped. Next, the supporting means is caused to enter the lower side of the uppermost storage holder. Next, when the frame and the mountain are relatively separated from each other, the uppermost empty storage holder is taken out of the mountain while being supported from below by the support means. At this time, since the bead with the filler is pressed against the second-stage storage holder by the presser claw receiving the urging force of the spring as described above, the bead with the filler is deformed and partly becomes the uppermost storage holder. Even if the adhesive beads are adhered, the uppermost storage holder is reliably separated from the filled beads, and the filled beads are not taken out together. Then, when the elevating body descends to the lower limit and comes into contact with the stopper, the elevating body separates from the mountain integrally with the frame.

Further, according to the second aspect of the present invention, since each support claw can be moved over a wide range in the radial direction, even when the mountain is inclined obliquely, the entire support claws can be moved. The uppermost storage holder can be supported from below by the support claws, and the take-out is ensured.

Further, according to the third aspect, it is possible to easily take out a plurality of types of storage holders having different sizes.

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 11 denotes a storage holder for storing a bead B with a filler, and the storage holder 11 is formed of a highly rigid resin. Each of the storage holders 11 has a truncated conical shape that expands downward and has a through hole that penetrates up and down and expands downwardly.
12 are formed. Each of the storage holders 11 has an inclined portion 13 having a truncated cone shape. The inclined portion 13 has a constant thickness irrespective of the axial position, and does not deform even when subjected to some external force. Reference numeral 14 denotes a mounting portion that is continuous with the upper end of the inclined portion 13, and the mounting portion 14 has a ring shape extending radially inward from the upper end of the inclined portion 13, and has an inner diameter (the minimum inner diameter of the storage holder 11). Have the same diameter as indicated by the imaginary line even if the sizes are different. Reference numeral 15 denotes a substantially cylindrical supporting portion extending upward from the lower end of the inclined portion 13, and the axial distance of the supporting portion 15 is larger than the width of the bead C. As a result, when the storage holders 11 are sequentially stacked upward with the lower end of the support portion 15 abutting on the upper end of the support portion 15, a space 16 is formed between the adjacent storage holders 11. The beads B with filler stored in the storage holders 11, that is, the beads C mounted on the mounting portion 14 and the fillers F arranged so as to surround the outside of the inclined portion 13, are located in the space 16. I do. A flange 17 protruding radially outward is provided on the outer periphery of the lower end of the support portion 15.
And these storage holders 11 are beads B with filler.
Are stacked in a plurality of stages on a vertically movable mounting table (not shown) in a state where they are mounted to form a mountain 18.

An elevating plate 20 which is moved up and down by a cylinder or the like (not shown) is disposed above the hill 18, and an up-and-down movement coaxial with the axis of the storage holder 11 constituting the hill 18 is provided on the lower surface of the elevating plate 20. The shaft 21 is fixed. The elevating plate 20 and the elevating shaft 21 as described above constitute a frame 22 that can be relatively approached to and separated from the mountain 18.

As shown in FIGS. 1, 2 and 3, a horizontal substantially triangular plate-shaped support 23 is fixed to a lower end portion of the elevating shaft 21, specifically, an elevating shaft 21 above an elevating body 37 which will be described later. A plurality of pairs (here, three pairs) of rollers 24 are rotatably supported on the support 23 at equal angles. 25 is a horizontal disk cam provided coaxially with the elevating shaft 21 and provided directly above the support 23,

The disc cam 25 is formed with a plurality of (three in this case) cam grooves 26 which are inclined in the same direction with respect to the radial direction and extend linearly. Is inserted. Three pairs of guide blocks 28 are attached to the lower surface of the support member 23 at equal angles, and support claws 29 extending in the radial direction are supported by the pair of guide blocks 28 so as to be movable in the radial direction. Reference numerals 30 denote radially extending cam grooves formed in the support 23 immediately below the transmission member 27, and the central portions of the transmission member 27 fixed to the support claws 29 are inserted into these cam grooves 30. Have been. As a result, when the disc cam 25 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 inward in the radial direction, they can also pass through the minimum diameter portion of the through hole 12 of the storage holder 11, while when they move outward in the radial direction, the upper ends of the through holes 12 The lower surface, specifically, the lower surface of the mounting portion 14 can be contacted.
Reference numeral 31 denotes a multi-stage cylinder whose head side is supported by a shaft of one of the rollers 24, and a piston rod of the cylinder 31.
The tip of 32 is connected to the disc cam 25. As a result, when the cylinder 31 operates, the disc cam 25 rotates. The disc cam 25, the transmission member 27, and the cylinder 31 described above constitute a drive mechanism 33 that moves the support claws 29 in the radial direction in synchronization with the support 23, the support claws 29, and the drive mechanism 33. As a whole constitutes a support means 34 capable of supporting the storage holder 11 from below when it enters the lower side of the storage holder 11.

1, 4 and 5, a sleeve 36 is slidably fitted to the elevating shaft 21 below the support 23.
An elevating body 37 similar to the support body 23 is attached to the sleeve 36. As a result, the elevating body 37 and the sleeve 36 can move up and down with respect to the frame 22, specifically, the elevating shaft 21. A plurality of pairs of rollers 38 are rotatably supported on the elevating body 37 as described above. 39 is the lifting body 37
The disk cam 39 is rotatably supported by a roller 38. A cam groove 40 similar to the cam groove 26 is formed in the disc cam 39,
Transmission members 41 are inserted into these cam grooves 40, respectively. A plurality of pairs of guide blocks are provided on the upper surface of the elevating body 37.
A plurality of pressing claws 43 circumferentially displaced from the supporting claws 29 are supported on the paired guide blocks 42 so as to be movable in the radial direction. Reference numeral 44 denotes cam grooves formed in the elevating body 37 and extending in the radial direction. These cam grooves 44 have a transmission member 41 fixed to the pressing claw 43.
Is inserted at the center. When the holding claws 43 move inward in the radial direction, the holding holder 11
Can also pass through the minimum diameter portion of the through-hole 12, while
When it moves outward in the radial direction, it can be pressed from above by contacting the bead with filler B placed on the placement portion 14 of the storage holder 11. Reference numeral 45 denotes a multi-stage cylinder whose head side is supported by a shaft of one of the rollers 38. The tip of a piston rod 46 of the cylinder 45 is connected to the disc cam 39. As a result, when the cylinder 45 operates, the disc cam 39 rotates, and the pressing claw 43 moves in the radial direction. The disk cam 39, the transmission member 41, and the cylinder 45 described above constitute a moving mechanism 47 that moves the pressing claw 43 in the radial direction synchronously. A spring 51 for urging the elevating body 37 downward, that is, toward the mountain 18 is interposed between a step 50 formed on the elevating shaft 21 above the elevating body 37 and the sleeve 36. A ring-shaped stopper 52 is fixed to the lower end of the elevating shaft 21.
52 is a sleeve when the elevating body 37 is lowered to the lower limit.
The lower limit of the elevating body 37 is determined by contacting the elevating body 37. A plurality (three in this case) of arc-shaped guide bodies 53 are fixed to the radially outer end of the elevating body 37 at equal angles, and each of the guide bodies 53 extends vertically. The distance from the axis of the elevating shaft 21 to the outer surface of the upper end portion of each guide body 53 is half the inner diameter of the mounting portion 14 in the storage holder 11, that is, the through hole 12
Is approximately equal to the minimum radius of Further, the outer surface of the lower end of each guide body 53 is inclined so as to approach the inside in the radial direction as it goes downward, and is tapered as a whole. As a result, for example, by taking out the bead B with filler,
Even if 18 is inclined and the uppermost storage holder 11 is displaced from the normal position, when the elevating body 37 is lowered, the guide body 53 is easily inserted into the through hole 12 of the uppermost storage holder 11,
Moreover, the uppermost storage holder 11 is centered and returned to the normal take-out position. The above-described lifting / lowering body 37, presser claw 43, moving mechanism 47, spring 51, stopper 52, and guide body 53 as a whole, when taking out the empty storage holder 11 at the uppermost stage, the second stage located immediately below the uppermost stage. The bead with filler B placed in the storage holder 11 of
The separation means 54 is configured to be pressed against the storage holder 11 at the tier to reliably separate from the storage holder 11 at the uppermost tier.

Again, in FIG. 1, reference numeral 57 denotes a plurality (here, three) 57 whose base ends are fixed to the elevating shaft 21 above the support 23.
These arms 57 extend in the radial direction. At the tip of each arm 57, an arc-shaped guide 58 extending vertically is integrally formed. The distance from the axis of the elevating shaft 21 to the outer surface of the upper end of each guide 58 is half the inner diameter of the mounting portion 14 in the storage holder 11, that is, the through hole 12
Is approximately equal to the minimum radius of Further, the outer surface of the lower end of each guide 58 is inclined so as to approach the inside in the radial direction as it goes downward, and is tapered as a whole. As a result,
The storage holder 11 removed from the mountain 18
When they are fitted to the outside of the
The center of the empty storage holder 11 is prevented from being inclined by the center 58.

Next, the operation of the embodiment of the present invention will be described. Now, it is assumed that a plurality of storage holders 11 on which the beads B with filler are respectively placed on the placement unit 14 are stacked to form a peak 18, and the peak 18 is placed on the placing table. At this time, the frame 22 is raised and stopped, and the empty storage holders 11 centered by the guides 58 are stacked and placed on the support claws 29 moving outward in the radial direction. In this state, a bead take-out device (not shown) removes the bead B with filler from the uppermost storage holder 11 and empties the uppermost storage holder 11. Next, the empty storage holder 11 and the like supported by the frame 22, the support claw 29, the guide body 53 and the support claw 29 are lowered to approach the mountain 18, and the separating means 54 is inserted through the uppermost storage holder 11. Hole 12
Let in. At this time, the guide body 53 is inserted into the through hole 12 of the uppermost storage holder 11 even if the peak 18 is inclined due to the removal of the bead B with filler and the uppermost storage holder 11 is displaced from the normal position. Then, the uppermost storage holder 11 is centered and returned to the normal take-out position. At this time, since the pressing claw 43 of the separating means 54 is moving inward in the radial direction, the pressing claw 43 does not come into contact with the mounting portion 14 of the storage holder 11. When the pressing claw 43 of the separating means 54 reaches a little above the bead B with filler placed on the second-stage storage holder 11 located immediately below the uppermost stage, the frame 22 descends (the peak 18). Stop approaching). At this time, the support claws 29
The empty storage holder 11 supported by is transferred onto the uppermost storage holder 11.

Next, the piston rod 46 of the cylinder 45 is protruded, and the disk cam 39 is rotated forward. As a result, the plurality of pressing claws 43 move outward in the radial direction in synchronization with each other, and the tips of the pressing claws 43 reach directly above the beads B with filler placed on the second-stage storage holder 11. Next, the piston rod 32 of the cylinder 31 is retracted, the disc cam 25 is rotated in the reverse direction, and the support claw 29 is synchronously moved inward in the radial direction. As a result, these support claws 29 are detached from the empty storage holder 11 that has been supported up to now. Next, the mounting table and the mountain 18 are raised by one pitch, that is, by the same distance as the height of the support portion 15, so that the mountain 18 approaches the frame 22. In the middle of the ascent of the mountain 18, the bead with filler B placed in the second-stage storage holder 11 is pressed against the tip of the holding claw 43 from below. Since the bead B with the filler is pressed against the pressing claw 43 in this manner, the peak 18 further rises, so that the pressing 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 the spring 51 stores an elastic force. Then, the elastic force stored in the spring 51 is applied to the pressing claw 43 as an urging force, and the bead B with the filler is strongly pressed against the second-stage storage holder 11 by the pressing claw 43. At this time, the support means 34 enters the through hole 12 of the uppermost storage holder 11. And mountain 18
Is raised by one pitch, the support claws 29 of the support means 34
Is lower than the mounting portion 14 of the uppermost storage holder 11 and 2
It reaches the support position above the bead with filler B placed on the storage holder 11 of the tier. Next, the support means
The disc cam 25 is rotated forward by projecting the piston rod 32 of the cylinder 31 of 34. As a result, the support claws 29 move radially outward in synchronization with each other, and the tips of the support claws 29 enter the lower side of the placement portion 14 of the uppermost storage holder 11. When the support claws 29 are moved in the radial direction in this manner,
Since each support claw 29 can be moved over a wide range in the radial direction, even when the mountain 18 is inclined, the tips of all the support claws 29 are held at the uppermost storage holder. The storage holder 11 can be moved below the placement section 14 of the storage section 11 and the removal of the storage holder 11 is ensured.

Next, the frame 22 is raised, and
22. Separate the support means 34 from the peak 18. At this time, the support claws 29 come into contact with the lower surface of the mounting portion 14 of the uppermost storage holder 11, so that the empty uppermost storage holder 11 is taken out of the mountain 18 while being supported from below by the support claws 29. . At this time, since the bead B with filler is pressed against the second-stage storage holder 11 by the pressing claw 43 receiving the urging force of the spring 51 as described above, the bead B with filler is deformed and Even if the storage holder 11 is partially adhered, the uppermost storage holder 11 is reliably separated from the bead B with filler, and the bead B with filler is not taken out together with the storage holder 11. Also, at this time, since the lifting body 37 and the presser claw 43 are urged downward by the spring 51, they stop at a fixed position regardless of the raising of the frame 22, thereby
The frame 22 will descend. Then, the elevating body 37 and the like descend to the lowermost limit at which the sleeve 36 contacts the stopper 52, and thereafter, the
Separated from 18. Thus, the storage holder 11 taken out from the mountain 18 becomes the lowermost stage of the storage holder 11 stacked on the support claw 29. Then, the mountains of these empty storage holders 11 are raised
Is fitted to the outside and is prevented from being centered and inclined. Next, when the frame 22 returns to the initial position,
The piston rod 46 of the cylinder 45 retracts, and the pressing claw 43 moves synchronously inward in the radial direction. The above is one cycle of the operation of the embodiment of the present invention. Thereafter, this cycle is repeated, and the storage holders 11 are taken out one after another. When the sizes of the storage holder 11 and the bead B with filler are changed, the strokes of the piston rods 32, 46 of the multi-stage cylinders 31, 45 are changed.

In the above-described embodiment, the cylinders 31 and 45 are multi-stage cylinders for taking out storage holders having different sizes. In the present invention, however, the disk cam is required to have a required amount by an electric motor, a rotary actuator or the like. It may be rotated only.

[0019]

As described above, according to the present invention, even if a part of the bead with the filler at the immediately lower stage is sticky, only the empty storage holder at the uppermost stage is used to remove the bead with the filler. Can be reliably separated and taken out.
