Description

Detailed Description of the Invention: This shaft extracts 4i of material from a coil attached to an uncoiler.
This invention relates to a device for automatically supplying a coil to an upper ad uncoiler on a shirring line that is cut to a predetermined length while being pushed out.

As shown in Fig. 7, the shirring line usually involves feeding out material C from coil b attached to uncoiler a.
First, curls are removed using a leveler d to bring it into a growing state, then the surface of the material C is cleaned using a cleaning device e, and then the material C is cut to a predetermined length using a shearing device f to form a material g of a predetermined length.

By the way, in order to supply the coil b to the uncoiler a, conventionally, the uncoiler 8 is made rotary, and this uncoiler is equipped with two arms h for attaching the coil 14,
h' is provided protrudingly, and during the shearing of coil b, the next coil b' is attached to arm h' for setup, and when coil b is used up, uncoiler a is rotated 180 degrees to replace coil b'. It was common to use it for shearing.

However, in such a conventional coil supply device, there is a limit to the number of arms h and h' that can be obtained with the uncoiler-aK arrangement, and the limit is 8, so the coil b.

b' to arms h and h', respectively, and then
The time it takes for a person to install the next coil is short, and it is unavoidable that the coils must be installed more frequently, requiring 1 out of 7 workers per job. Furthermore, with conventional devices, it is almost impossible to automate the supply of coils, which has been a bottleneck in automating the shearing line.

The present invention provides a coil car that is provided with a plurality of coil carts on which individual coils are placed so that they can run along mutually parallel routes, and that can selectively receive these coil carts and run in a direction across the above-mentioned routes. Provided, the end of the coil car is Qm 1
If you set the coil on the selected coil trolley to the uncoiler in the row position (face down), you can automate the supply of coils, and you can obtain multiple stages of coil trolleys without any restrictions. Coil once on all coil carts W, t f
By leaving the coil in the uncoiler position, the coils can be automatically set to the uncoiler one after another without any human intervention until all the coils are used up, and all of the above problems can be solved. (This is an attempt to provide an automatic coil supply device for a shirring line characterized by -R configuration.

Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments.

is a roller 20 attached to the tip of the arm 19 so as to be rotatable for 1 m.
This is driven by a motor 2]. Arm 10
is rotated by a hydraulic cylinder 22, and as a result of this rotation, the roller 20 is appropriately pressed against the outer peripheral surface of the coil 18. This It;'? The roller '20 tightens the outer periphery of the coil 18 to prevent the tip of the coil 18 from springing up when the band is cut by the band cutter 6 as described later, and also to tighten the coil 18 so that material is fed out from it as shown in FIG. It can be rotated and driven in the counterclockwise direction of the hour hand.

The band cutter 6 includes a cutter head z4 attached to the tip of an arm z8, and an arm 2'? ) to hydraulic cylinder 2
5 allows rotation 1, and this rotation brings the cutter head 24 into contact with the outer periphery of the coil 18. The cutter head '24 detects the tip of the coil while the coil 18 is being rotated in the material feeding direction 5, and cuts the band at the outer circumferential surface of the coil and the gap between the bands.

The band cut in this way falls from the coil 18, and this band is placed in one piece and transferred to the magnetic conveyor 2.
6, and by this conveyor the band chip device z

The leveler 7, the cleaning device 8, and the shearing unit 8 are ordinary ones, but the leveler 7 is provided with a fixed guide 29 and a movable guide 81 that can be rotated by a hydraulic cylinder 80, and the tip of the coil 18 is disposed between them. to ensure that it is guided to the leveler 7. The tilt conveyor 1o can be tilted by a hydraulic cylinder 82 between the solid line position and the imaginary line position in FIG. The conveyor lO is located at the imaginary line position K, and the above-mentioned tip and end crystals are disposed of in the storage tank 83. However, the material cut to a predetermined length by the yarning device 9 is stored in the stacker 11 by the tilt conveyor 1o at the solid line position. Then let it cool and use it for processing.

Figure 8 shows the details of the coil truck 1 and tow truck 2 viewed from the side, and Figure 4 shows the details of the tow truck 2 seen from above. As shown in Fig. 1, a frame 84 is provided, and wheels 85 are mounted at each of its four corners.
is provided for each rotation. A rail 13 corresponding to each wheel 35
By arranging it so that it rolls over the top, the coil truck I is made to move 44 i'hj on the rail/I/18. The pedestal 84Vc further includes a pair of coil support members 86 that receive the outer peripheral surface of the coil 1B and are inclined in the tangential direction of the coil, thereby positioning the coil 12 in the rolling direction relative to the coil truck 1. so that it can be placed on top. The pedestal 84 is also provided with two pairs of claws 81 and 88 for preventing the coil 12 from falling down, and one pair of claws 87 is provided with the hand-if (il
1, and the other pair of claws 88 are arranged close to the opposite side of the coil 12 in FIG.
A rotatable shaft 39 is fixed to the frame 34.

A lever 40 is fixed to each shaft 89, and a hydraulic cylinder 4z (only one of which is visible in the CVS diagram) is pivotally attached to the tip of the lever via a pin 41. Thus, the pawl 88 is rotated by the hydraulic cylinder 4z between the open position shown by the solid line and the imaginary line (closed) fjkli which is located at a distance J' overlapping the pawl 87 and prevents the coil 12 from falling. can move.

As shown in FIGS. 8 and 4, the towing turret 2 is provided with a mount 44, and a wheel holder 5 is rotatably provided at each of the four inner corners of the mount 44.

Each wheel 45 is arranged so as to roll over the corresponding rail 18, thereby making the tractor 2 movable on the rail 18. Then, a motor 46 is installed on the frame 44, and the intermediate ll1b4a is rotatable via a bearing 47. Binions 51 are fixed respectively. Drive pinion 49
and the middle southeast 50 are aligned 1.1 with each other, and the driven binion 51 is engaged with the rack 5z fixed to the rail 1B' (Lill).

Thus, when the motor 46 is applied with a force of 11 or more, the rotation is transmitted to the driven pinion 51 via the drive pinion 49, the intermediate gear 5o, and the intermediate shaft 48, and this driven pinion rolls on the rack 5zKe. , Sumibiki Tadashi 2 can run on the rail 13 by itself.

In this way, a hook 53 projecting toward the coil truck l is fixed to the self-propelled truck 3 44 of the self-propelled truck 2, and the hook 54 that engages with the hook 53 is attached to the coil truck fft, 1 as shown in FIG. t
r>Fixed to the pedestal 84. Therefore, the surface coil truck 1 on which the towing vehicle 2 self-travels can also move integrally on the rail 18. The shapes of the hooks 53 and 54 are selected so that they can be engaged and disengaged in the vertical direction (direction perpendicular to the drawing in FIG. 4), as shown in FIG. 4, so that the purpose described below can be achieved.

Next, details of the coil car 3 will be explained with reference to FIGS. 5 and 6. The coil car 3 also includes a mount 55, and the 4
Wheels 56 are provided at each corner. Each wheel 56 is arranged to roll over the corresponding rail 14, the paired wheels 56 are wedged to a common axle 57, and each gourd 57 is rotatably supported on a pedestal 55. A drive pinion 6 is mounted on one side of the axle 57, and this gear is fixed to the four outputs 11 of the Tanabata 59 on the mount 55.
0 mesh.

Thus, when the motor 5g is driven, its rotation causes the drive pinion 60, the driven tooth ijj 58, and the associated city shaft 5 to rotate.
The coil car 8 is transmitted to the car 56 mounted on this axle via 7, and each wheel 56 rolls on the rail 14, making the coil car 8 self-propelled on the rail 14.

The frame 55 is further provided with a pair of rails 61 extending perpendicularly to the rails 14 on its upper part, and these rails are arranged at the same level as the rails 1B as shown in FIG. 8, and the width between the rails 61 is The width should be equal to the width between the rails 13. Thus, while the coil car 3 is stopped at a position 4 where the rail 61 is aligned with the rail 13 as shown in FIGS. and can be located on the coil car 3 as shown in FIG. As shown in FIG. 6, a lifting platform 6z is provided for raising the coil truck 1, and this lifting platform is connected to a frame 5.
It is supported on a hydraulic cylinder 68 attached to 5. The hydraulic cylinder 63 moves the lifting table 62 from the lowering position shown in the actual record in FIG. It can be raised through the imaginary line position in figure a, or conversely lowered.

In order to prevent the lifting platform 62 from shifting laterally or rotating during vertical movement, a pair of guide rods 64 are provided protruding from the lower surface of the lifting platform 62, and these guide rods are connected to the mount 55, respectively.
It is slidably inserted into the guide bush 65 provided in the guide bush 65.

Further, a guide frame 66 is fixed to the upper surface of the lifting table 6z 12.
, when the lifting platform (52) rises to the imaginary 6-position in FIG. The shape of this guide frame 6G is selected so that it can penetrate closely.

This causes the coil stand 17.1 to rise further, causing the coil stand 17.1 to move away from the rail 61.
Temporary figure in Figure 6? 1E (even when the coil car is falsely lifted at the f9 position), the coil platform can stop the shoulder and descent (1z, therefore, the positional deviation θ relative to the coil car 8) by 315 degrees.

The operation of the above-mentioned F& structure according to the present invention will be briefly explained.0 Before starting the shearing line, each coil truck 1 is retreated by the tractor 2 to 1 t■ as shown in the 1st ■ and z [41]. It is stopped at this position. When the worker places the coil 12 on the coil cart l as shown in Figures 1 to 3 and starts the shearing line, the device of the present invention automatically supplies the coil as follows. Do the following. 17
11th, coil car 3 reaches rail 14 due to self-propulsion of the front 6 cars.
, then move to °0 and first prioritize 1st place (for example, ?K
Coil Taitun 17 of 11 Zo 1 Middle Ding (11111)! l
'$ ili Align the rail 61 with the rail 13 to be applied (see Figures 1 and 2) and automatically stop at this position. Detecting this stop, the coil truck 1 is moved forward to the left in Figures 1 to 3 by the self-propelled movement of the towing vehicle 2, and transfers from the rail 13 to the rail 61 (however, the towing vehicle 2 (remain between rails 13). When this transfer is completed, the coil truck l is moved to a predetermined position on the coil car 3 as shown in FIG. When it reaches this point (tJi), the towing vehicle 2 stops its self-propulsion and the coil truck 1 is stopped at this position.

At the same time, the oil field cylinder 63 automatically extends and lifts the lifting platform 62 ;f! Figure 5 shows Bozu-F limited standing position 1 with real legs 6
Place the upper back between the middle points shown by the imaginary lines in the figure. This lifts the coil truck l, and its hook 54 (ff
The engagement with the hook 53 (see Figure i4) is removed, and the connection between the coil base 1 and the towing vehicle 2 is released. After that, the coil car 8 automatically starts the above-mentioned self 7L, and the rail 14
15@ of uncoiler 4 by moving upward in Figure 1 along the
The vehicle temporarily stops at this position (the traction ff12 remains at the advanced position of 1 qtl).

At this time, if any previous coils still remain on the mandrel 17 of the uncoiler 4, which one is detected and the coil car 8
is directly 1111st and 1115' of uncoiled sea 4 (!I) and waits until the coil is finished being shirred.

When the coil on the mandrel 17 is exhausted, the oil 1 cylinder 63 further extends and valves the lifting platform 62, causing the coil truck 1 to rise by -1 from the 6th temporary resuscitation section (jLji'-). Light V protrusion shown in Figure 1: J, 4 J
ji is the vertical line 1 [(and the coil 1
8 is detected, and when this intersection α reaches a predetermined level as shown in FIG.
Stop the above increase in z. Then, the coil car 3 moves forward further, and the coil 18 (see Fig. 2) on the coil stand 1 (1°1) placed on it is fitted and set on the mandrel 17 (the mandrel 17 holds the coil as shown in 4 above). (The diameter of the coil truck is reduced inwardly when it disappears).Up to this point, the claw 88 of the coil truck has been closed to the position of the imaginary line in Fig. 3 by the hydraulic cylinder 42. , 8
Hold the coil 12 (1B) on 81rl and attach the coil stand Tl.
(On l, this coil 12 (18) continuously during τe movement
It is possible to prevent J1: from falling down.

When the coil car 8 is fully advanced, the coil 18 on the coil stand TLl mounted on it is moved to the mandrel 17 as shown in Fig. 2.
Once the 11 coils have been set, the coil car 8 automatically stops, and the mandrel 17 expands its diameter to clamp the 18 coils. Thereafter, the corner 1 on the coil stand 1 is opened at the corner j1 (the claw 88 is solid in FIG. The coil stand 11 can be transferred from the uncoiler 4 without interfering with the coil stand 11. Next, the coil car 8 moves backward along the rail 4 in a direction away from the uncoiler 4 (downward in FIG. Close it to the imaginary line position in FIG. When the coil car 8 returns to the received position VC as shown in FIG. The lower limit position and 1-position are indicated by . At this time, each wheel 35 of the coil truck 1 rides on the rail 61, and the hook 54 of the coil truck 1 is connected to the hook 5 as shown in 4+R+.
8 to connect the coil truck 1 to the towing vehicle 2.

In this state, the towing vehicle 2 moves backward by self-propulsion as described above, and lifts the coil truck 1 from the rail 61 to the rail 1B''21C.
Then, the coil truck 1 automatically stops the backward movement at point 11, when the coil truck l reaches the backward limit position from vg 1 v+ to the backward limit position in FIG.

When the coil 18 is completely fed onto the mandrel 17 as described above, the roller 20 of the coil presser 5 and the cutter head 24 of the band cutter 6 shown in FIG. Ru. The roller 2o rotates the coil 18 in the material feeding direction (counterclockwise in the piZz diagram) r = M < fJ3, and the cutter head z4 detects the tip of the coil 18 during this rotation and cuts the outer peripheral surface of the coil existing here and this In the gap between the bands that fasten the band
It is possible to feed out the material from. Note that the roller 20 can prevent the coil 18 from jumping up due to this band cutting ~i. One end of the cut band as described above is adsorbed by the magnetic conveyor 20 and carried into the band chipping device 27, where it is cut into chips and discarded in the storage 1N92s.

After cutting the band 1, the cutter head 24 is removed from the coil 18 by the hydraulic cylinder 25, but the roller zO continues to be pressed against the outer peripheral surface of the coil 18 to rotate them. As a result, the tip y11 of the coil 18 initially comes into contact with the movable guide 31, which has a position of 9 in FIG. Thereafter, the material from the coil 18 is moved one step by the leveler 7, and since the rotation of the coil 18 by the roller 20 is not necessary, the roller 20 is separated from the coil 18 by the hydraulic cylinder 22. Further, after the coil tip field is carried into the leveler 7, the movable guide 31 is flipped up by the hydraulic cylinder 80, and is directed toward the leveler 7 while guiding the material to be paid out between it and the fixed guide 29.

After the leveler 7 removes the curls from the material being fed out, the material is poured into a cleaning device 8 where the material is cleaned. After that, the material is sequentially cut into predetermined lengths by the shearing device 9, but the monthly yield at the tip and end of the coil 18 is unusable due to leakage and poor quality of the straight 9, so these ketilt conveyors lO Around 1, it is disposed of in the storage tank 88 by tilting (virtual line position 1 shift in Figure 2), and the remaining cut to regular length is stored on the stacker 11 by the tilt conveyor 10 at the solid line position in Figure 2, It is used for the next processing.

During the shearing process of the coil 18, the coil car 8, which has returned the coil car 1 to the original rail 1B as described above, moves to the next coil car 1 (for example, the second coil car J(1) from the bottom in FIG. 1). The traveling rail 1BK rail 61 is self-traveled along the rail 14 in order to make it full, and then receives the coil stand in the same manner as described above, waits at the position immediately before the uncoiler 4, and then the coil 18 is Wait for the shearing process to be completed. When this shearing process is completed, the coil on the coil truck l mounted on the coil car 8 is set in the uncoiler 4 as described above.

Thereafter, by repeating the above action, until fy when there are no more coils on the uncoiler 4, the coils on each coil truck 1 are sequentially supplied onto the uncoiler 4, and all the coil trucks 1 are supplied to the uncoiler 4.
Coils can be automatically supplied to the uncoiler 4 without any manpower until the upper coil is used up.

Thus, the device according to the invention can be operated, for example, as described above.

A plurality of coil carts l each carrying a coil lZ,
A coil car 8 is provided which can run along mutually parallel routes 13 and can selectively receive these coil carts l and run in a direction across the route 18.
Since the coil 18 on the selected coil truck 1 is set in the uncoiler 4 at the terminal running position of the uncoiler 4, the supply of coils can be easily and completely automated using various well-known limit switches, photoelectric detectors, sensors, etc. Also, if you can install a large number of coil carts without any restrictions and place coils -IK on all of these coil carts, it will take a considerable amount of time (for example, one day's operation) until all the coils are used up. Time) - Coils can be automatically supplied to the uncoiler 4 one after another without the need for manual labor, making it possible to omit a dedicated worker.
