Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ring-shaped object handling device that can reliably and easily handle a bundle of ring-shaped objects hung on a stand.

Conventionally, it is necessary to handle ring-shaped objects such as so-called coils or tires, which are formed by winding wire rods, hoop materials, etc. in a donut shape, individually for inspection, measurement, packaging, storage, etc. in the next process. There are many cases where this happens.

For example, in order to separate and take out coils one by one, conventionally, as shown in FIG. C is successively manually shifted laterally so that hook b etc. can be inserted into its center, and then hung using hook b of a forklift or crane and separated, or the hooks are brought close to each other. It is necessary to suspend the coil from the hook by tilting the coil toward the hook, and the handling requires a large amount of man-hours and is inefficient and sometimes even dangerous.

The present invention is based on the use of a ring-shaped object mounting means and a ring-shaped object hanging means having a hook that can move back and forth and up and down relative to the ring-shaped object mounting means and has an inclined upper side. An object of the present invention is to provide a ring-shaped object handling device that can solve the problems associated with the individual handling of ring-shaped objects.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the ring-shaped object handling device of the present invention will be described below with reference to the drawings.

FIG. 1 illustrates a case where the ring-shaped object is a coil and the device of the present invention is used as a coil separation device (in the following examples, the term "coil" will be used instead of the word ring-shaped object).
.

The coil separation device 1 is a first rail 21a installed on the ground surface.

In this embodiment, the hook truck 5 forms a hook hanging means B, and the coil trucks are arranged in two series in parallel, so that when the separation and weighing of the coils placed on one coil truck 2a is completed, the other coil truck 2a is awaited. Separation and extraction of the coils on the coil truck 2b is started to enable continuous coil separation and extraction work.

The coil mounting means A, that is, the coil carts 2a and 2b, is made up of a pair of coil mounting rails 22, 22 whose upper surfaces are arranged in an inverted angle, and a back plate 23 for hanging a coil stand erected at the rear of the rails 22, 22. The rear wheels 24.24 are connected to the first brake-equipped deceleration motor M1, and the first rails 21a, 21 are moved by the deceleration motor M1.
b is moved back and forth intermittently in a predetermined cycle.

Note that the coil carts 2a and 2b have ring-shaped objects, that is, coils c1 to
cn are placed in a line with their center holes aligned.

As shown in FIG. 2, the traveling bogie 4 includes a rectangular frame 42, and a pair of wheels 43 pivoted on the frame 42 are connected to a second reduction motor M2 with a brake via a chain device 44. Said second rail 31 on the portal frame 3
At the same time, the hook carriage 5 is moved by the third rail 41 formed on the upper end of the rectangular frame 42 in the longitudinal direction.
The wheels 51 of the vehicle are guided.

A rond end 81 of an air cylinder 8 is fixed to the hook truck 5, and a base 82 of the air cylinder 8 is pivotally supported by a clevis 45 attached to the traveling truck 4, so that expansion and contraction of the air cylinder 8 is controlled. The accompanying hook truck 5 travels on the traveling truck 4.

Furthermore, the hook cart 5 has a pair of winding discs 52, 52.
A hoisting shaft 53 having a fixedly attached hoisting shaft 53 is pivotally connected to the third brake-equipped reduction motor M3 shown by a chain line through a chain device 54, and a hook guide 5 is attached to the lower surface of the hoisting shaft 53.
5 is hung vertically and the hook 6 is extrapolated.

As shown in FIG. 3, the hook 6 consists of a top part 61, a body part 62, and a hanging part 63 at the lower end. , a pair of left and right mounting holes 66.66 are provided, through which a hoisting chain 67.67, one end of which is fixed to the hoisting discs 52, 52, and a coupling member 68°68 at the other end are inserted and fixed. By tightening, the hook 6 is suspended from the hook truck 5 so as to be vertically movable.

Further, the hook 6 is guided by the hook guide 55 and is held so as not to be able to swing.

A guide shaft 72 on the back surface of the layer plate 71 that holds the coil abutting plates 70, 70 at the front of the body is horizontally and slidably inserted into guide tools 69, 69 installed horizontally on the left and right side walls of the body 62.

Note that a spring a73 is inserted around the guide shaft 72 to constantly bias the coil contact plate 70 forward, and the rear adjustment nut 7
4 regulates its forward position, and an 11th second detector s 1 ; s2 is spaced apart from the rear end of the lower guide shaft 72.
are arranged side by side, and the coil abutting plate 7 is detected by the first detector S1.
0 and the coil is detected to stop the hook truck 5 at a predetermined relative position with the coil, while the output of the second detector S2 causes the hook truck 5 to come to an emergency stop.

The hanging portion 63 is tiltably attached to a support shaft 75 below the body portion 62, protrudes from between the coil abutting plates 70 and 70, and is arranged in a negative row in the coil direction X, that is, as shown in FIG. 4a. It has an upper side 63a that slopes downward toward the coil c1 located in the front row among the coils c1 to cn to be placed.

The projecting length of the hanging portion 63 is approximately equal to the maximum coil width T (illustrated in FIG. 4a) of the coil to be handled.

Therefore, when suspending a coil that is sandwiched between the maximum coil width dimension t, the tip of the hanging portion 63 protrudes from the coil.

The hanging portion 63 is biased clockwise in the figure by a spring b77 hooked to the end of an arm 76 fixed to the pivot portion.

In this embodiment, the hanging part 63 is always tilted at about 15 degrees by the locking pins 78a and 78b, and when the coil is suspended, it is tilted at about 20 degrees and then stopped. Activate the device S3.

A high friction plate 79, for example, a rubber lining, is attached to the upper side 63a of the hanging part 63 to prevent the suspended coil from slipping off, and the tip of the hanging part 63 is attached to the high friction plate 79.
It is bent into an arc shape starting from the vicinity of the front end, and a fourth detector S4 for hook collision detection is protruded from the bent portion.

The hook hanging means B can insert the hook 6 into the coil c1 located in the front row of the lining of the coils 01 to cn placed on the coil cart 2a, as shown in FIG. The hook 6 can be pulled up within a range that does not collide.

Next, the operation of the apparatus shown in FIGS. 1 to 3 will be explained using FIG. 4.

In FIG. 4a, the air cylinder 8 is shortened and the hook truck 5
is located at the rear end of the traveling truck 4, and the traveling truck 4 is
The position of the hook 6 is aligned with the running line of the coil carts 2a and 2b (described below with reference to the coil cart 2a) on which the coils cl, c2...Cn are placed, and the hook 6 is

make you look forward to it.

Next, the coil trolley 2a is advanced and the hanging portion 63 of the hook is
is interpolated into the coil row, and the coil truck 2a is
The foremost coil C1 comes into contact with the coil contact plate 70 and is stopped by operating the first detector S1 (Fig. 4b).
In this example, the coils 01 to cn are interleaved, and the hook 6 is inserted into the coil c1 in the front row, so that the tip of the hanging portion 63 protrudes from the coil c1.

Note that when the coil truck 2a moves forward until the second detector S2 is activated, the truck suddenly stops at that position to prevent damage to the hook.

The first detector S1 detects that the hanging part 63 is the foremost coil c.
1, the output operates the third reduction motor M3 with a brake, and the winding disc 52.52
rotates, and the hook 6 is raised to a position where the upper side 63a of the hanging portion abuts the inner upper end of the coil c1 (FIG. 4C) and the third detector S3 is activated.

Thereafter, the hook 6 is moved again to a distance of 11, that is, approximately 3 in this example.
The coil is raised by about 0 to 50 degrees, and only the tip of the coil C1 is suspended from the hook 6 as shown in FIG. 4d.

Note that the upper side of the hanging part 6a is tilted at 20 degrees and its tip is bent in an arc, so that even when the hook moves up the distance 11, the protruding part does not collide with the adjacent coil c2 and is pulled up. The coil is prevented from sliding down by the high friction plate 79.

In the next step, the coil cart 2a is separated by a distance of 12 meters, that is, approximately 300 to 700 meters in this embodiment, the suspended coil c1 is completely separated, and the third reduction motor M3 with brake is driven to further distance the coil truck 2a by a distance of 13 meters, for example. The weight is raised by about 300 to 400 meters (Fig. 4e), and the traveling trolley 4 is driven to transport it to the weighing machine 9.

Thereafter, the hook is lowered to seat the lower end of the coil, and the air cylinder 8 is extended to retreat the hook 6, thereby removing the coil c1.

After that, the traveling truck 4, air cylinder 8, etc. move forward and return to the initial state, completing one cycle.

Note that the fourth detector S4 at the end of the hanging portion 63 detects a collision with the coil, stops the coil truck 2a, and provides a signal for correcting the initial position of the hook 6.

When the separation of the coils on one coil carriage 2a is thus completed, the expected separation of the coils on the other coil carriage 2b is started.

An empty coil truck is attached to a C-hook (such as a crane).
(not shown) or the like, the coil is placed on the coil mounting rail 22 while leaning against the back plate 23 of the coil truck.

As a result of the device of the present invention having a structure similar to a main ball, when handling a ring-shaped object such as a coil, it is possible to reliably pull up only one ring-shaped object without colliding with an adjacent ring-shaped object, and to use a ring-shaped object mounting means, a hook, etc. Various operations such as separation can be performed by moving the hook forward and backward and up and down relative to the hook hanging means that suspends the hook, and by attaching a high friction material such as a rubber lining to the hanging part 63, the coil can be prevented from falling off. Completely preventable.

In the above embodiment, the coil carts 2a and 2b were described as moving back and forth intermittently, but the ring-shaped object mounting means was left stationary, and only the hook hanging means was moved back and forth with respect to the mounting means. It can also be configured to move relatively up and down.

Furthermore, in addition to the coil separating device, the ring-like object apparatus of the present invention is also provided with a ring-like object aligning and gathering device as shown in FIGS. A device is used in which the ring-shaped body R1 that has been removed is once pulled up by the hook 6 and then placed thereon, thereby aligning it along the adjacent ring-shaped body R2. Alternatively, the ring-shaped body transported from another place by the hook 6 is directly pulled up by the hook 6, and then placed on the hook 6. It can also be used in addition to various devices for inspection, packaging tubes, etc. that align and place the tubes.

The angle of inclination of the hanging part is usually 10° to 30°, which is relatively easy for a ring-shaped object with stable shape, such as a tire, and steeply for something that has a small ability to maintain its shape. degree, and the hanging part 63 is set at the upper side 63 of the tip part.
It is also possible to incline only a.
