Description

[Detailed Description of the Invention] [Industrial Application] The present invention is useful for transferring a plurality of cylindrical objects such as cheese in a spinning process from a winding position to an accumulation position, for example. The present invention relates to a multi-transfer device used.

[Prior Art] Conventionally, a multi-purpose machine is capable of holding a plurality of cylindrical objects at once and transferring them to a stacking table using a plurality of vertically and horizontally movable chucks provided at regular intervals. Transfer devices are known.

[Problems to be solved by the invention] By the way, for example, in the case of cheese etc. in the spinning process, -
°The intervals at the winding position are wide so that the winding operation is not obstructed, and conversely, when stacking on the mount placed on the stacking table, it is necessary to close the intervals to save space. There is.

However, the conventional multi-transfer device has a problem in that it cannot meet the above-mentioned requirements because it simply moves and reloads the cylindrical object while leaving the interval between the chucks unchanged, that is, the interval between the cylindrical objects to be transferred.

Means for Solving Problem L] The measures taken to solve the above problem will be explained with reference to FIG. 1, which corresponds to an embodiment of the present invention. A width adjustment rail 2 is provided, a chuck 3 is provided to be slidable along the width adjustment rail 2, and a connecting rod drive stand 4 that can be moved close to and separated from the pedestal 1 is supported on the pedestal 1. Rod drive base 4 and the chuck 3
A connecting rod 5 is pinned diagonally between them, and the chuck 3 is slid along the width shifting rail 2 as the connecting rod 5 tilts as the connecting rod drive base 4 moves. The above-mentioned problem is solved by the chuck width adjustment mechanism of the loading device.

[Function] If the interval between the chucks 3 is adjusted to the interval between the cylindrical objects 6 to be transferred and then the pedestal l is moved to the position of the cylindrical objects 6,
A cylindrical object 6 can be held in each chuck 3, and by subsequent movement of the pedestal 1, the cylindrical object 6 can be transferred to a predetermined position.

When the connecting rod drive base 4 is moved with the cylindrical object 6 held in each chuck 3, each connecting rod 5 is tilted, and the chuck 3 is accordingly slid along the width adjusting rail 2. At this time, if the slope and length of each connecting rod 5 are added appropriately,
Each chuck 3 slides along the width adjustment rail 2 in the direction of convergence, and the intervals are made even. In this way, the intervals between the chucks 3, in other words, the intervals between the respective cylindrical objects 6 held on the chucks 3 are reduced, and the pedestal is moved to a predetermined position, and the cylindrical objects 6 are removed from the chuck 3. If this is released, the cylindrical objects 6 can be transferred with a smaller interval between them.

On the other hand, even if the pedestal 1 moves, the connecting rod drive base 4 supported on the pedestal 1 also moves, so the connecting rod 5 does not tilt due to the movement of the pedestal 1, and each chuck 3 The adjusted interval is maintained by moving the rod drive base 4.

[Example] In FIG. 1, cylindrical objects 6, such as cheese used in a spinning process, are arranged upright on a workbench 7 at intervals suitable for winding operations and the like. A stacking table 8 is provided adjacent to this working table 7, and the cylindrical objects 6 that have been subjected to the required work on one working table 7 are transferred onto the collecting table 8 at short intervals.

A traveling rail 9 is provided above the workbench 7 and the accumulation table 8, and the pedestal 1 is suspended from a pedestal vehicle 10a traveling on the traveling rail 9 via a hydraulic cylinder 11a arranged upward. ing. Therefore, this gantry l is moved horizontally when the gantry car 10a travels on the running rail 9, and is moved vertically when the hydraulic cylinder 11a is actuated to move between the work platform 7 and the accumulation platform 8. It has become.

The pedestal 1 is provided with a plurality of width-adjusting rails 2 directed toward one point on a plane. A chuck 3 is provided on each of the valley width shifting rails 2 so as to be slidable along the width shifting rail 2. The pedestal 1 has a hollow frame shape, and each chuck 3 projects downward from the pedestal 1.

At the top of the hydraulic cylinder 11a that suspends the pedestal 1, there is a
A fixed base 12 is attached, and the connecting rod drive base 4 is suspended from the fixed base 12 via a hydraulic cylinder 11b arranged downward. Therefore, the connecting rod drive base 4 moves in the horizontal and vertical directions as the pedestal 1 moves, and when the hydraulic cylinder 11b is actuated, it is moved close to and separated from the pedestal 1 in the vertical direction.

A mounting piece 13 protrudes from the bottom surface of the connecting rod drive stand 4.
A connecting rod 5 is connected between this mounting piece 13 and the base of the chuck 3.
is pinned. The connecting rods 5 are each tilted in the same direction as the width shifting rail 2. Although the vertical movement of the connecting rod drive stand 4 and the moving direction of each chuck 3 differ depending on the direction of inclination of the connecting rod 5, in this embodiment, each chuck 3 moves up and down as the connecting rod drive stand 4 moves up. As the connecting rod 5 tilts in the upright direction, it moves in the direction of convergence to a point on the plane toward which the valley width shifting rail 2 is directed, and when the connecting rod drive base 4 descends, the connecting rod tilts in the direction of collapse. It moves in the direction of diffusion.

The mechanism for adjusting the width of the chuck 3 as the above-mentioned connecting rod drive base 4 moves up and down will be further explained.

In FIG. 2, it is assumed that the chucks 3 are provided in 3 x 4 rows, and their positions are indicated by O marks (A+ to D3) and 0 marks (A'+''D'3).

The 0 marks (A+ to D3) are the positions corresponding to the spacing of the cylindrical objects 6 on the workbench 7, and the 0 marks (A'1 to D'2) are the positions for accumulating the cylindrical objects 6 on the stacking table 8. The position where the chuck 3 is biased is shown.

As is clear from the figure, in the illustrated case, B
Centripetal biasing is performed centering on the chuck 3 located at position 2. That is, the chuck 3 at 32 points is fixed to the pedestal l, and except for this point B2,
The chuck 3 at points A+ to D is connected to the connecting rod drive stand 4
Due to the tilting of the connection s5 with the rise of
'Move to 3 points, and the intervals between each chuck 3 are evenly reduced.

Further, the biasing rail 2 is provided in the sliding direction of the chuck 3 shown in the figure, that is, on a radial line extending from point B2 to other points A1 to D3, and guides the movement of each of the chucks 3. . If you want to further reduce the interval between the cylindrical objects 6 to be transferred onto the stacking table 8, by further raising the connecting rod drive table 4, the positions indicated by the Δ marks (A″1 to D″3) in the figure can be reached. Each chuck 3 can be moved to the next position.

In this embodiment, the biasing rail 2 is provided toward one point on the plane, but if biasing is only required in one direction vertically or horizontally, the valley width shifting rails 2 may be provided in parallel. Moreover, if the biasing amount is different in the vertical direction and the horizontal direction, the biasing rail 2 will not move toward one point.

Here, as shown in FIG. 3, the fulcrum 14a of the connecting rod 5 on the chuck 3 side is separated by A in the horizontal direction and B in the vertical direction from the fulcrum 14b of the connecting rod 5 on the connecting rod drive base 4 side. When the connecting rod drive base 4 is raised and the fulcrum 14b is pulled up by y, the chuck 3 moves toward the biasing rail 2.
It is assumed that the fulcrum 14a moves by X by sliding along the axis. Letting the length of the connecting rod 5 at this time be expressed as follows, the following equation holds true.

Sentence 2 =A2+B2...(1
)12 = (A-x) 2 + (B+y) 2
・-(2) The tilting of the M connection 5 is the same as the connecting rod drive base 4.
Assuming that y is the same for all chucks 3, the difference in biasing amount
It can be adjusted by setting the initial position of 14b. For example, for a certain chuck 3, the amount of bias up to the 0 mark in FIG.
, the amount of bias up to the Δ mark is x2, and the corresponding lifting amount of the connecting rod drive stand 4 is Yl, Y2, then from equations (1) and (2) above, the following simultaneous equation (3) is obtained. To establish.

X2. From A, B and the statement for each chuck 3 obtained as a function of V2 and determined based on this, the connecting rod 5
What is necessary is to adjust the length and the positions of both fulcrums 14a and 14b.

Returning to FIG. 1 for further explanation, first, the intervals between the chucks 3 are adjusted to the intervals between the cylindrical objects 6 on the workbench 7, and the pedestal 1 is correctly positioned directly above the workbench 7, and then the hydraulic cylinder 11a is activated to lower the pedestal 1. As a result, the tip of each chuck 3 is inserted into the head of the cylindrical object 6, so that the cylindrical object 6 is held by spreading the tip of each chuck 3.

After each chuck 3 holds the cylindrical object 6 in this manner, the hydraulic cylinder 11a is operated again to raise the pedestal 1. After the gantry 1 has been sufficiently raised, the hydraulic cylinder 11b is operated to raise the connecting rod drive stand 4-, and the chuck 3 is biased by the aforementioned biasing mechanism. After this biasing or while performing biasing, the gantry vehicle 10a is run to move the gantry 1 in the horizontal direction and position it directly above the stacking platform 8. At this time, the platform car 10b for supplying the paper 15 onto the stacking table 8 has been moved to a position where it does not get in the way.When the platform l has moved to just above the stacking table 8, the platform car 10a
is stopped, and the hydraulic cylinder 11a is activated to lower the pedestal 1 again. When the cylindrical objects 6 held by each chuck 3 are properly received on the mount 15 on the receiving table 1B of the stacking table 8, the tips of the chucks 3 are closed and the pedestal 1 is raised to complete the transfer. . The cylindrical object 6 transferred onto the mount 15 is sent together with the mount 15 to the next stage of the process, and onto the receiving table 16 of the stacking table 8 is attracted by the suction nozzle 17 and transported by the mount vehicle lOb. The new mount 15 that has been brought is lowered and replaced by the operation of the hydraulic cylinder 11c. □ In this embodiment, each chuck 3 is provided facing downward, but the illustrated chuck width adjusting mechanism may be oriented horizontally or upwardly, so that each chuck 3 can be oriented horizontally or upwardly.

By the way, the cylindrical objects 6, such as cheese, for example, are normally stacked in an upright state with their cores inserted into insertion holes provided in the mount 15 on the receiving table 16.

Therefore, the mount 15 is placed in the correct position on the receiving table 1B, and the core of the cylindrical object 6 is placed on the mount 1B despite the slight deviation.
It is necessary to guide it to the insertion hole No. 5.

The stacking table 8 that performs center alignment with the mount 15 will be explained with reference to FIGS. 1 and 4.

The receiving table 16 of the stacking table 8 is formed with openings 18a corresponding to the number of cylindrical objects 6 to be transferred at one time, and a tubular core 19 is placed onto the receiving table 16 from each opening 18a. stands out. A collar body 20 is attached to the base of this core body 18. The upper surface of the collar body 20 is located at a position that substantially coincides with the upper surface of the receiving table 1B.

'A support body 21 is attached to the lower part of the collar body 20.

Further, below this, a rack table 2 is supported by a hydraulic cylinder lid provided upward on the fixed table 22.
3 is located, and on this rack table 23, a guide rail 24 is provided toward a point on the plane, similar to the width adjusting rail 2 described above. A support body 21 attached to the lower part of the flange body 20 is attached to be slidable along this guide rail 24. Therefore, when the hydraulic cylinder lid is operated and the rack table 23 is moved in the vertical direction, the core body 18 is retracted or protruded from the receiving table 16 accordingly.

A hydraulic cylinder lie is attached to the rack table 23 facing downward, and the connecting rod drive table 25 is suspended by this hydraulic cylinder lie. An opening 18b corresponding to the opening 18a of the receiving table 16 is formed in the rack table 23. A connecting rod 2B, which is inclined toward the guide rail 24, is pinned between the support body 21 and the connecting rod drive table 25 through this opening 18b. Therefore, the protruding position of the core body 19 can be adjusted within the range of the openings 18a and 18b by moving the connecting rod drive table 25 in the vertical direction using the hydraulic cylinder lie, in the same manner as in the width adjustment mechanism described above. It can be adjusted according to the width adjustment amount. However, for example, the core body 18 located at the 32 points explained in FIG.
It is fixed to the rack table 23 and does not move in the horizontal direction as the connecting rod drive table 25 moves.

A plurality of grooves 27 are formed in the vertical direction on the peripheral wall of the core body 19, and from each groove 27, a groove 27 is bent into a 6-shape and can be pushed in elastically when the cylindrical object 6 is fitted. The spring 28 is bulging. The upper end of the spring 28 is fixed to the head of the core unit 8, and the lower curved part is connected to the groove 27.
It bulges out from the Further, the outer diameter connecting the expanded spring 28 almost matches the inner diameter of the insertion hole of the mount 15 and the outer diameter of the core of the cylindrical object 6, and the lower part of the upper part of the core 18 receiving table IB. The outer diameter substantially matches the inner diameter of the core of the cylindrical object 6 (the inner diameter of the cylindrical object 6).

First, the core body 18 is projected onto the receiving table 16 at a position corresponding to the widthwise transfer position of the cylindrical object 6 to be transferred.
put. Then, when the mounting car 10b is positioned directly above this and the mounting paper 15 is supplied, even if the position of the supplied mounting paper 15 is slightly shifted, the insertion hole of the mounting paper 15 is inserted into the core body 19 forming the tapered tube shape. By getting into it and being guided by it,
It is automatically corrected to the correct position and placed on the receiving table 16.

Then, instead of the frame car lOb, the frame car foa is moved to the stacking platform 8.
The pedestal 1 is moved upward, and the pedestal 1 is positioned directly above the receiving table 18, and the chuck 3 holding the cylindrical object 6 is lowered. At this time, even if the position of the protruding core body 19 of the cylindrical object 6 held by each chuck 3 is slightly shifted, the inner periphery of the cylindrical object 6 will still fit into the tapered core body jll. You will be guided. Moreover, the spring 2 expands until the core of the cylindrical object 6 pushes the spring 28 and the core fits between the core 27 and the flange 20.
Since the mount 15 is maintained in the correct position by the mount 8, there is no possibility of a transfer failure due to a positional shift of the mount 15 once the mount 15 is placed in the correct position.

After inserting the core of the cylindrical object 6 into the insertion hole of the mount 15 and transferring it as described above, the hydraulic cylinder lid is operated to lower the rack table 23 downward, and the core 19 is transferred to the receiving table 18. If you pull it in from above, the transferred cylindrical object 6 will be placed on the mount 1.
Each step can be easily sent to the next process.

[Effects of the Invention] According to the present invention, the cylindrical objects can be transferred with the widths of the cylindrical objects narrowed and the intervals narrowed.1 For example, when the transferred cylindrical objects are directly packed, etc. , it can be made into a small package without any manual intervention. Furthermore, there is no need to manually re-arrange them at closer intervals, which greatly simplifies the work.
