DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing a packaging material protecting a wound body such as paper or film, and more particularly to an apparatus for removing a packaging material which protects a wound body such as paper or film.
Packing materials such as paper and film surrounding the end surface of the winding body,
The present invention relates to a packaging material removing device for removing a protective material such as a metal stopper or a plastic stopper inserted into an end of a core.

[0002]

2. Description of the Related Art In general, a winding body such as a paper or a film has a peripheral surface and an end surface protected by a packing material, and a protective material may be inserted into an end portion of a winding core. FIG.
(F) shows various examples of the packing state of the winding body, 1 is a winding body, 2 is a core, 3a is an end packing material, 3b is a peripheral packing material, and 4 is the inside of the winding core 2. It is a protective material inserted in.
The protective member 4 includes a member without a flange (see FIGS. 10E and 10F) and a member with a flange (see FIGS. 10C and 10D). When attached so as to be exposed outside the packing material 3a [FIGS. 10C and 10E]
See FIG. 10 (d) and FIG. 10 (f).

Conventionally, in order to remove the packaging material of such a wound body, the boundary between the end packaging material 3a and the peripheral packaging material 3b is cut off to separate them, and the end packaging material 3a and the protection material 4 are separated. After that, the peripheral packing material 3b is cut and removed. Here, an apparatus for cutting the boundary between the end packing material 3a and the peripheral packing material 3b to separate them from each other is disclosed in JP-A-1-103293.

[0004]

However, in the apparatus disclosed in the above publication, the cutting operation is automatically performed.
There is no discharge device for the separated end packaging material,
Therefore, it is necessary for an operator to grasp the end-face packing material by hand and remove it from the end face of the winding body, which is not only unsanitary, but also involves a problem that labor costs are increased due to the necessity of working personnel.

Conventionally, no device has been developed for removing the protective material 4 inserted into the core. Therefore, conventionally, an operator grasps the protective material 4 by hand and pulls it out, or a hook portion is provided at the tip. Pass the formed rod through the center hole of the protective material 4,
The tip of the rod is hooked on the protective material 4 and pulled out, or the protective material 4 is protruded from the opposite side of the core through the rod. However, there is a problem that the method of grasping and pulling out the protective material 4 by hand cannot be adopted when the protective material 4 is tightly fitted in the core. Also, the method of hooking and pulling out the rod tip from the protective material 4 is such that the rod is easily detached from the protective material, and the rod tip is hooked and pulled out only at one position away from the center of the protective material. However, there has been a problem that it is difficult to pull it out. Further, in the method of projecting the rod through the opposite side of the core, it is also difficult to project the protective material, and there is a problem that the operation is troublesome.

The present invention has been made in view of the above-mentioned conventional problems, and it is possible to remove an end face packing material and / or a protective material from a wound body without requiring much troublesome and unsanitary work. It is an object of the present invention to provide a simple packing material removing device.

Another object of the present invention is to provide a packaging material removing apparatus capable of automatically removing an end face packaging material and / or a protective material from a wound body and discharging the material to a predetermined position.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a chuck device having a plurality of opening / closing claws and an opening / closing device for opening / closing the opening / closing claws; A pushing member held by the chuck device so as to be positioned and reciprocate along the central axis of the plurality of open / close claws; and a reciprocating motion for reciprocating the chuck device in the central axis direction of the plurality of open / close claws. The gist of the present invention is a packaging material removing device having a driving device.

Here, it is preferable to provide a rocking device between the chuck device and the reciprocating drive device for rocking the opening / closing claw from a horizontal position to a downward position. Further, it is preferable that a reciprocating drive device, a swinging device, a lifting device for lifting and lowering the chuck device, and a revolving device for rotating the reciprocating drive device, the rocking device, and the chuck device around a vertical axis are further provided.

[0010]

In the apparatus of the present invention described above, with the opening and closing claws of the chuck device closed, the reciprocating drive device moves the opening and closing claws from the end surface of the winding body to the packing material (the end packing material and / or the protective material in the core). ) Is inserted into the core, and then the opening / closing claw is opened by the opening / closing device, and then the opening / closing claw is pulled out of the core by the reciprocating drive device. Alternatively, it is possible to hold the protective materials and remove them from the winding body. When removing the end face packing material, the end face packing material is separated from the peripheral packing material in advance.

Here, when the end face packing material and the protective material are held by the opening / closing claw and removed from the winding body, or when only the end face packing material is held by the opening / closing claw and removed from the winding body, the opening / closing claw is provided. Is moved to the stacking position of the end face packing material, and the pushing member is protruded forward at that position, so that only the end face packing material can be pushed and removed from the protective material or the opening / closing claw. Removal of the end packing material from the opening / closing claw may be performed with the opening / closing claw being horizontal (in a state where the end packing material is vertical). In this case, it is preferable to perform the operation with the opening / closing claw facing down and the end face packing material kept horizontal because the discharged end face packing material can be collected neatly.

The protection member held by the opening / closing claw may be removed manually by an operator. However, as described above, a swinging device is provided between the chuck device and the reciprocating drive device. By turning the open / close claw holding the protective material downward and closing the open / close claw, the protective material can be automatically removed, which is convenient.

When the lifting device is provided, the height of the opening / closing claw can be arbitrarily adjusted by the lifting / lowering device, and the opening / closing claw can be positioned at the winding core position even for winding bodies having different winding diameters. It becomes possible. For this reason, it is possible to remove the packaging material of the winding body having various diameters. In addition, if a swivel device is provided, the opening / closing claw can be swiveled about a vertical axis, and an end face packing material accumulation position and a protection material accumulation position are provided around the vertical axis, and the winding member is moved from the winding body. The removed end face packing material and protective material can be discharged to their collecting position. As described above, by arranging these accumulation positions around the vertical axis, space can be effectively used.

In FIG. 1 and FIG.
Are provided so as to be movable in a horizontal direction indicated by an arrow XX and a vertical direction indicated by an arrow YY. That is, the moving frame 28 is held by a horizontal moving member 40 that is configured to reciprocate horizontally by a motor, a pinion, a rack, or the like (not shown). It is a configuration to do. The horizontal moving member 40, the moving frame 28, etc.
Is reciprocated in the central axis direction of the plurality of open / close claws in a horizontal state.

The moving frame 28 is held by a horizontal moving member 40, and a spherical bearing 44 is provided on a holding portion thereof. In any direction,
It can swing in a small angle range (for example, about ± 5 degrees).
Thereby, even when the position of the opening / closing claw 21 is slightly misaligned when the opening / closing claw 21 is inserted into the protection member 14 attached to the winding body 11, the opening / closing claw 21 is inserted into the protection member 14 without any trouble. be able to. Further, a clamp member (not shown) for fixing the moving frame 28 to the spherical bearing 44 is provided in the moving frame 28.

The elevating device 42 is mounted on a rotary table 46 that is configured to rotate about a vertical axis, so that the moving frame 28, the swinging device 32 held by the moving frame 28, the chuck device 20 and the like are vertically mounted. It is pivotable about an axis. Therefore, the rotary table 46 and its driving device (not shown) constitute a reciprocating drive device, a swinging device, and a turning device for turning the chuck device around the vertical axis. Instead of providing the elevating device 42 on the turntable 46, the turntable 46 itself may be capable of elevating and lowering, which may be used as an elevating device.

In FIG. 2, a sensor 48 for detecting the uppermost position of the winding body 11 is provided at the tip of the horizontal moving member 40. Also, in FIG.
In the vicinity of 8, there are a protection material accumulation position and an end face packaging material accumulation position. In each accumulation position, a protection material container 50 for accommodating the protection material 14 removed from the winding body 11 and the end face packaging material 12 are accumulated. A trolley 51 is disposed.

Next, the operation of the packaging material removing apparatus having the above configuration will be described. The following operations are sequence-controlled by a control device (not shown).

Normally, as shown in FIGS. 1 and 2, the moving frame 28 is at a predetermined raised position, and the chuck device 20 has its opening / closing claw 21 horizontal and faces the direction of the winding body 11. It is in a closed state. The pressing member 26 (see FIG. 3) is in a state of being retracted near the chuck device main body 23.

In FIG. 1, the winding body 11 is supplied onto a packaging material cutting device 16, at which position the winding body 11 is rotated to cut the boundary between both ends of the peripheral packaging material 13 and the end packaging material 12. Is started. During this cutting operation, the packaging material removing device 1
8 is started.

First, the moving frame 2 is moved by the lifting device 42.
8 is lowered, and the chuck device 20 is lowered. The sensor 48 that moves down with the moving frame 28
After detecting the uppermost surface of the winding body 11, the distance between the sensor 48 and the central axis of the chuck device 20 in the height direction is further determined.
After the moving frame 28 is lowered by a distance corresponding to the difference from the radius, the lifting device 42 stops. As a result, the chuck device 20 stops and is positioned at a position facing the winding core 15 of the winding body 11.

Next, the horizontal moving member 40 moves horizontally,
The moving frame 28 is moved toward the winding body 11. As a result, the chuck device 20 advances, and the opening / closing claw 21 penetrates through the protective member 14 and is inserted into the core 15 as shown in FIG. At this time, the position of the opening / closing claw 21 of the chuck device 20 may be slightly shifted from the center of the winding core 15 of the winding body, but the movable frame 28 is freely moved by the spherical bearing 44 by releasing the clamp member in the movable frame 28. Since it can move, it is inserted into the protection member 14 without hindrance. At this time, the support block 30 (see FIG. 4) is at a position where the swing device 32 has been advanced by the internal air cylinder. The moving device 32 is mounted on the support block 30.
Withdrawal, and no trouble occurs.

After that, when the packaging material cutting operation by the packaging material cutting device 16 is completed, the opening / closing device 2 of the chuck device 20 is opened.
2 operates to open the opening / closing claw 21 (see FIG. 5B), and then a clamp member (not shown) in the moving frame 28.
Operates to fix the moving frame 28 so as not to move with respect to the spherical bearing 44. In this state, moving frame 2
The retractable claw 8 pulls the opening / closing claw 21 from the core 15. As a result, as shown in FIG.
4 is hooked and pulled out by the locking portion 21a of the opening / closing claw 21, and the end face packaging material 12 is removed from the winding body 11 while being held by the protection material 14. Here, since the pair of opening / closing claws 21 is provided, the locking portion 21a is hooked at a symmetrical position across the center of the rear end of the protection member 14, so that the hooking is secure and the protection member 14 is axially oriented with respect to the protection member 14. A force can be applied, and the protective member 14 tightly fitted to the core 15 can be reliably pulled out.

When the opening / closing claw 21 is opened, depending on the condition of the packing material [for example, as shown in FIG. 10 (e), there is also the end packing material 3a at the rear end of the protective material 4, and the end packing material 3a. When the opening 3a is pierced by the opening / closing claw], the opening / closing claw 21 may be difficult to open. In that case, the opening force applied to the opening / closing claw 21 may be increased (for example, when an air cylinder is used, the air pressure may be increased). However,
For example, as shown in FIGS. 10A and 10B, when there is no protective material, when the opening / closing claw 21 is pulled out from the core 15 with the opening / closing claw 21 opened by applying a large opening force, The opening / closing claw 21 may be caught on the inner surface of the winding core 15 on the way, causing a trouble. In such a case, the opening and closing claw 2
It is preferable that the opening / closing claw 21 is opened by giving a large opening force to 1 and then the opening force is reduced (air pressure is reduced) and the opening / closing claw 21 is pulled out from the core 15.

As described above, the protective member 14 is
After the end surface packing material 12 is removed from the winding body 11, the rotary table 46 is rotated, the moving frame 28 and the chuck device 20 and the like held thereon are turned, and the moving frame 28 is moved forward. As shown by the dotted line,
The chuck device 20 is located above the carriage 51. Next, the oscillating device 32 (see FIG. 4) operates to turn the chuck device 20 downward, and then the pushing member 26 moves forward as shown in FIG. 5 (d). As a result, the pushing member 26 pushes the end face protection member 12 attached to the protection member 14 downward, and removes the end surface protection member 12 from the protection member 14. Thus, the end face protection member 12 falls downward and is accumulated on the carriage 51. Then, FIG.
, The rotary table 46 rotates in the direction opposite to the previous direction, and the moving frame 28 retreats,
0 is positioned above the protective material case 50 and then the protective material 14 is removed by closing the opening / closing claw 21. Thus, the protective material 14 is discharged into the protective material container 50.

Thereafter, each member returns to the original position, and one package material removing operation is completed. During this time, the end face packing material 1
The winding body 11 from which 2 and the protective material 14 have been removed is discharged to the next step. Hereinafter, by repeating the same operation,
Removal of the end face packing material 12 and the protection material 14 of the winding body 11 is continuously performed.

In the above description, the case where the flanged protective material 14 and the end face packaging material 12 are simultaneously removed from the winding body 11 has been described. However, the packaging material removing device 18 having the above configuration is not limited to this case. 10 (e), it can be similarly used when the protection member 4 without the flange and the end face packing material 3a are simultaneously removed from the winding body having the shape shown in FIG.

In addition, the packing material removing device 18 having the above-described structure
The present invention can be used not only when the end face packing material and the protection material are simultaneously removed from the winding body but also when only the protection material 14 is removed. In that case, before the end face packing material 12 is separated from the peripheral face packing material 13, the opening / closing claw 21 is inserted into the protection material 14, and the opening / closing claw 21 is opened and pulled out, so that only the protection material 14 can be removed. . FIG.
In the winding body 1 of the type shown in (d) and (f), after removing the end face packing material 3a, it can also be used for removing the protective material 4.

Further, as shown in FIGS. 10 (d) and 10 (f), the packing material removing device 18 having the above-described structure is used to remove the protective material 4 from the wound body in which the outside of the protective material 4 is covered with the end face packing material 3a. It can also be used when simultaneously removing 4 and the end face packing material 3a.
FIG. 6 illustrates a case in which the protective member 4 and the end face packing material 3a are simultaneously removed from the wound body of the type shown in FIG. 10D, and the opening / closing claw 21 of the chuck device 20 is attached to the end face packing material 3a. By piercing and inserting into the protective member 4 and then opening and closing the opening and closing claws 21, the end face packing material 3 a and the protective member 4 are held by the opening and closing claws 21 as shown in FIG. It can be removed from the winding body. In order to remove the end face packing material 3a and the protective material 4 from the opening / closing claw 21, first, the chuck device 20 is placed on the protective material container 50 (FIG. 1).
6), and then, as shown in FIG.
At this position, the opening / closing claw 21 is closed, and the pushing member 26 is pushed out to the intermediate position several times to lightly tap the end face packaging material 3a. As a result, only the protection member 4 falls off the nail. Thereafter, as shown in FIG. 6C, the opening / closing claw 21 is opened again,
With the end face packing material 3a held, the chuck device is moved above the carriage 51 (see FIG. 1), the chuck device 20 is directed downward at that position, the opening / closing claw 21 is closed, and the pushing member 26 is advanced. As a result, the end face packing material 3a is dropped downward and collected on the carriage 51. As described above, the end face packing material 3a and the protection material 4 can be removed.

As shown in FIGS. 10 (a) and 10 (b), the packing material removing device 18 having the above structure can be used for removing the end face packing material 3a from a wound body without using a protective material. Also in that case, the chuck device 20 is attached to the end face packing material 3a.
By piercing the opening / closing claw 21, and opening and pulling it out, the end face packaging material 3a can be removed from the winding body 1. However, before that, the end face packing material 3a is
Needless to say, it is separated from b.

Although the packing material removing device 18 of the above embodiment has a structure in which the swing device 32 is provided so that the chuck device 20 can be directed downward, the swing device 32 is not essential to the present invention. Can be omitted. For example, when the packing material removing device 18 is used only for removing the end surface packing material, the swinging device 32 may be omitted, and the opening / closing claw 21 may be always kept in a horizontal state. In this state, after the end face packaging material is removed from the winding body by holding it on the opening / closing claw 21, the pushing member 26 can be advanced in this state to remove the end face packaging material from the opening / closing claw.

Further, in the above-described embodiment, the turning device is provided to turn the chuck device 20 around the vertical axis. However, the turning device can be omitted.
In this case, the moving stroke of the moving frame 28 may be increased, and the accumulation positions of the protective material and the end face packing material may be arranged on a straight line. When the packing material removing device 18 is always used for a wound body having the same diameter, the height position of the winding core is always constant, so that the chuck device 20 is positioned at the height position. In addition, the lifting device may be omitted.

Opening / closing claw 21 used in the above embodiment
Has a configuration in which a locking portion 21a protruding outward is provided at the tip, and the end of the protection member 14 or 4 is hooked by the locking portion 21a. However, when the protection member can be removed relatively easily,
The locking portion 21a may be omitted, and the outer surface of the opening / closing claw 21 may be pressed against the inner surface of the protective material to be held.

In the above description, the pushing member 26 has been described as being used for removing the end face packing material 12 or 3a held by the opening / closing claw 21, but the pushing member 26 is used for other purposes. It is also possible. FIG. 7 shows an example of this. When the opening / closing claw 21 is hooked on the protective material 14 and pulled out, the pressing member 26 is pressed against the end face of the winding body 11. While pressing the pressing member 26 against the end surface of the winding body, the chuck device 20 is moved leftward,
When the protective member 14 is pulled out from the core 15 by the opening / closing claw 21, the pulling force of the protective member 14 against the core 15 is reduced by the pressing member 26.
, And the sum of the pulling force of the opening / closing claw 21 and
Extremely large. Therefore, the tightly fitted protective material 1
4 can be reliably pulled out.

FIG. 8 shows a modification of the chuck device. The chuck device 20A shown in FIG. 8 has an electromagnet 55 attached to the front surface of the chuck device main body 23, and when the iron protection member 14 is pulled out, the protection member 14 is connected to the electromagnet 5
5, the gripping force of the protection member 14 by the chuck device 20A is increased, and the tightly fitted protection member 14 is fitted.
Is configured to be able to be reliably pulled out.
With this configuration, after the protection member 14 is pulled out, the chuck device 20A is turned downward, and the electromagnet 55 restrains the protection member 14 even when the pushing member 26 is advanced to remove the end face packing material 12, so that the protection member 14 Can be prevented from coming off together.

FIG. 9 shows still another modification of the chuck device. The chuck device 20 </ b> B shown in FIG. 9 includes a rotatable auxiliary pawl 56 at a position where the flange of the flanged protection member 14 held by the opening / closing pawl 21 is gripped. This auxiliary claw 56
Normally waits at the position shown by the two-dot chain line in FIG. 9A, and holds the protection material 14 and the end face packing material 12 on the opening / closing claw 21 and at the same time, as shown by the solid line,
The protective member 14 is restrained by entering between the protective member 14 and the flange of the protective member 14 so that the gripping force of the protective member by the chuck device 20B is increased, and the tightly fitted protective member 14 can be reliably pulled out. It is configured as follows. Then, FIG.
As shown in (b), after the chuck device 20B is turned downward, the pushing member 26 advances to push out the end face packaging material 12. As described above, since the auxiliary claw 56 restrains the protection member 14, it is possible to prevent the protection member 14 from coming off together when the end face packaging material 12 is removed. The chuck device 20
In B, the push member 26 has a structure separated at the position of the auxiliary claw 56 so as not to interfere with the auxiliary claw 56 when the push member 26 moves forward.
