DETAILED DESCRIPTION OF THE INVENTION

[0001]

Field of the Invention The present invention relates to a tube for cutting a tube extruded from an extruder into a plurality of rings of a predetermined width continuously and efficiently without stopping the extruder. The present invention relates to a body cutting device and a cutting machine.

[0002]

2. Description of the Related Art As a rubber roller for paper feeding or the like used in office equipment such as a copying machine, a facsimile machine, and a printer, for example, a rubber member having a small width rubber ring pressed around a core material is used. There are cases.

In order to form this ring body, conventionally, as shown in FIG. 16, (1) a tubular body a continuously extruded from an extruder
Are sequentially cut with a guillotine cutter b to prepare in advance a long tubular base a1 having a length of an integral multiple of the width of a desired ring body a2 + α (corresponding to an ear); (2) this tubular base A temporary core d coated with a lubricant c is inserted into a1; (3) The tubular base a1 with the temporary core is mounted on a lathe supporting both ends, and fixed cutter blades f arranged at intervals of a predetermined width.

However, the conventional method has the following problems. Since the tubular base a1 is pressed against the cutter blade f while rotating the tubular base a1, distortion of the tubular base a1 at the time of insertion of the temporary core and runout of the temporary core d and the cutter blade f result in double cut marks. Good products are easy to invite. In the case of the guillotine cutter b, the blade itself must have strength, and the blade becomes thick. As a result, the tubular body a is greatly deformed at the time of cutting, and distortion occurs at both ends of the tubular base a1. Therefore, it is necessary to form the tubular base a1 long by the length of α, and to cut off both ends together with the distortion, thereby causing waste of material. It is necessary to perform two-stage cutting in the order of “tubular body a” → “tubular base a1” → “ring body a2”, and transport work, temporary core insertion work, and removal of the ring body a2 from the temporary core during that time. In addition, the production efficiency is inferior, for example, an operation of cleaning the removed ring body a2 and removing the attached lubricant is required.

[0005] Accordingly, the present invention provides a method for guiding a tube-shaped body continuously extruded from an extruder to a cutting position through a festoon, and for pressing the tube-shaped body at the cutting position to a comb-shaped holding member. In a state where the cutting blade is pressed against the cutting table and the cutting blade is passed through each comb of the pressing tool, the tubular body is continuously formed without stopping the extruder, and a plurality of rings having a predetermined width are formed. An object of the present invention is to provide a tube-shaped body cutting device and a cutting machine capable of automatically and efficiently cutting a body with high accuracy and solving the above problems.

[0006]

In order to achieve the above object, the invention of claim 1 of the present application is to cut a tubular body continuously extruded from an extruder by a predetermined width in a longitudinal direction.

Thereby, the continuous movement of the tubular body W supplied from the extruder 2 via, for example, a cooling tank or a conveyor, and the movement at the time of intermittent cutting on the downstream side are adjusted. The festoon 3 is provided with, for example, three sensors SW (photoelectric sensors in this example) for detecting the storage amount, and detects the supply timing of the tubular body W to the cutting means 9 and the abnormality when the storage amount is exceeded. It is carried out.

Next, as schematically shown in FIG. 3, the receiving conveyor 4 of the cutting machine 100 comprises a non-driven roller conveyor attached to a gantry 11 in this embodiment, and the tube-shaped body W from the festoon 3 is removed. It is formed to include a main conveyor section 12 which receives and guides in the length direction F to the cutting table 6. In this example, the case where the receiving conveyor 4 includes the main conveyor portion 12 and a centering portion 13 including vertical guide rollers 13R disposed above and on both sides thereof is illustrated. In addition, the vertical guide roller 13 </ b> R is, for example, in the length direction F through a mounting frame 14 that straddles the gantry 11.
Are arranged in a line on both sides along the center line, and the tube-shaped body W is guided between the roller lines to perform centering. The centering portion 13 is configured so that the interval between the roller rows can be adjusted according to the thickness of the tubular body W.

In the main conveyor section 12, the most upstream roller is formed by a one-way roller 15L for preventing reverse rotation to the upstream side, and a tube is provided above the one-way roller 15L between the one-way roller 15L. A pinch roller 15U is provided so as to be able to move up and down to prevent the tube-shaped body W from moving backward in the upstream direction by pressing the tube-shaped body W.
In this example, the pinch roller 15U is pivotally supported by a rod lower end of an advancing and retreating tool 17 such as a cylinder, and the advancing and retreating tool 17 is held by, for example, a support bracket 18 that rises from the main conveyor section 12. .

Next, the cutting table 6 is arranged in parallel with the receiving conveyor 4 so as to be transitable, and the tubular body W is cut at the upper surface thereof. In the present example, the upstream end of the cutting table 6 is pivotally supported at a pivot point J provided on the gantry 11 and, as shown in FIG. An example in which it is supported to be tiltable to a position X2 will be exemplified. This tilting operation is performed by a rod operation of an advancing / retreating tool 19 such as a cylinder attached to, for example, a leg of the gantry 11.

At the payout position X2, the cutting table 6 is connected to a discharge conveyor (not shown) for discharging rolls, for example, through a shooter 20 having the same inclination.
In addition, at the stationary position X1, the downstream end of the cutting table 6 is supported by a support means 22 having a receiving metal member 21 which can move forward and backward in the longitudinal direction F so as to be freely detachable.

The support means 22, as shown in FIG.
It has an advancing and retreating tool 23 such as a cylinder to be attached to the gantry 11, and the receiving metal fitting 21 supported by a rod end 23A. The receiving fitting 21 has a pair of receiving pieces 21A having a receiving surface for receiving the lower surface of the downstream end of the cutting table 6, and each receiving piece 21A is connected to the rod end 2 via a connecting fitting 24.
3A, and is guided in the longitudinal direction F by, for example, a U-shaped guide guide 25.

Next, the guiding means 5 picks up the tubular body W on the receiving conveyor 4 at the picking position Y1 and guides it to the cutting position Y2 on the cutting table 6. As shown in FIG. 4, the guiding means 5 includes a chuck 27 for detachably holding the downstream end We (sometimes referred to as a distal end We) of the tubular body W, and a longitudinal direction F of the chuck 27. And a chuck moving tool 29 for moving the chuck.

The chuck moving tool 29 is provided on the moving table 3 movably arranged along a rail 36 extending in the longitudinal direction F.
7 and a moving means 39 for moving the moving table 37. The chuck 27 is attached to the movable table 37 via a support rod 40, and the rail 36 is
For example, it is supported by the gantry 11.

In the present embodiment, the moving means 39 is exemplified by a case where two reciprocating members 39A and 39B such as cylinders are connected in series.
Further, the other reciprocating tools 39B are fixed to the moving table 37, respectively.

Therefore, the moving table 37 is moved to the position Z on the most upstream side due to the contraction of both the reciprocating members 39A and 39B.
1 and an intermediate position Z2 by extending only one of the reciprocating members 39A, and a most downstream position Z3 by extending both of the reciprocating members 39A and 39B, and can move freely at three positions Z1 to Z3. . And the position Z on the most upstream side
1, the chucking tool 27 is positioned at the take-up position Y
The distal end We of the first tubular body W is gripped and received, and the distal end We gripped at the intermediate position Z2, which is the cutting position Y2, is released. After release, the chuck 27
Retreats to the most downstream position Z3 and waits for the next reception of the tubular body W.

As shown schematically in FIG. 5, the chuck 27 has a pair of insertion pieces 30 inserted into the distal end We of the tubular body W, and can move the respective insertion pieces 30 to the left and right sides. And an insertion piece holding means 31 for holding the distal end We of the tubular body W by pressing it flat and wide. In this example, the insertion piece 30 has a half columnar shape, and has a small diameter columnar shape which is easy to be inserted into the tube-shaped body W by approaching each other.

In the present embodiment, as the insertion piece holding means 31, as shown schematically in FIG.
And a pair of laterally moving pieces 33 having a slope 33S engaged with the wedge surface 32S of the wedge piece 32 and capable of sliding to both sides by the forward and backward movement of the wedge piece 32. . Reference numeral 34 in the figure denotes a spring for urging the respective laterally moving pieces 33 inward, and reference numeral 35 denotes a rod for driving the wedge piece 32 such as a cylinder or the like. In addition, as the insertion piece holding means 31, other well-known various mechanisms such as a mechanism using a cam to move laterally and a mechanism using a rack and pinion can be adopted.

Next, as shown in FIGS. 7 to 9, in the present embodiment, the fixing means 7 is moved up and down on a portal-shaped support frame 41 which straddles the cutting table 6 in a direction perpendicular to the length direction F. And a comb-shaped holding member 43 supported so as to be able to move up and down via the member 42.
Then, by the lowering of the presser 43, the tubular body W at the cutting position Y2 thus guided is pressed against the cutting table 6 and fixed flat.

The supporting frame 41 is composed of side frame members 41a and 41b erected on the gantry 11 and an upper frame member 4 connecting the upper ends thereof.
1c, and a mounting plate 44 is attached to one side frame member 41a.
The lifting and lowering tool 42 is fixed via the.

Here, in the present embodiment, the fixing means 7 includes a first fixing means 7A having a first holding member 43A for fixing the upstream half region of the cutting of the tubular body W, and the first fixing means 7A. An example is shown in which a second fixing means 7B having a second pressing member 43B which is arranged in parallel with the pressing member 43A and fixes the downstream half region of the cutting of the tubular body W is used.

The first and second fixing means 7A, 7B
The first and second holding members 43A, 43B are attached to the lower end of the rod 42a of the lifting / lowering member 42 supported by the mounting plate 44, respectively. The lifting device 4
As a second example, the present example illustrates a case where a cylinder with a built-in guide shaft 45 is used.

Each of the holding members 43A and 43B has a thick main portion 46 fixed to the lower end of the rod 42a, and a long elongated portion extending from the main portion 46 at right angles to the longitudinal direction F. A plurality of pressing shafts 47 are formed in a comb shape. Note that the comb eyes, which are the gaps G between the pressing shafts 47, 47, are formed at pitch intervals according to the width of the ring body W1 to be formed.

The reason why the fixing means 7 is constituted by the first and second fixing means 7A and 7B is that the guided tubular body W is prevented from being free and being displaced during fixing. To do that. That is, FIGS.
As shown in (B), the distal end We of the tubular body W guided to the cutting position Y2 is still the chuck 27
The holding tool 43A of the first fixing means 7A is lowered while being held by the first fixing means 7A. Thereby, the upstream half region of the region for cutting the tubular body W is pressed flat and fixed to the cutting table 6. Next, in this fixed state, the chuck 27 is released from the tip We and the standby position Z3
After retreating to the second position, the holding member 43 of the second fixing means 7B
B is lowered, and the remaining part (downstream half area) of the area to be cut is fixed.

As described above, by pressing down in two stages, the entire area of the tubular body W to be cut can be fixed with high accuracy without displacement. At this time, the chuck 27 also functions as a centering mechanism for fixing.
Note that the pressing force of the fixing means 7 is, for example,
The working air pressure on the descending side that operates is controlled by adjusting the precision pressure reducing valve. In this example, as shown in FIGS. The tubular member W comes into contact with the member and is pressed by a force that flattens the tubular member W into a band shape.

This flattening eliminates the necessity of cutting while rotating the tubular body W as in the prior art, thereby preventing the occurrence of double cut marks. Furthermore, in the cutting blade 49, the blade thickness can be greatly reduced together with the blade width, thereby preventing the cutting surface of the guillotine cutter from being distorted and enabling high-precision cutting.

Further, by making the holding member 43 in a comb shape, the tubular body W can be cut at once while using a plurality of cutting blades 49 and firmly holding the vicinity of each cutting blade 49. That is, it is possible to achieve both the high-precision cutting and the efficient cutting.

Next, as shown in FIGS. 7 to 10, the cutting means 9 separates the cutting blades 49 by a predetermined width. The tubular body W is cut into a plurality of ring bodies W1.

More specifically, the cutting means 9 includes a cutting tool 50 in which the cutting blades 49 are separated by a predetermined width,
And a moving tool 52 for moving the lifting / lowering tool 51 in a direction perpendicular to the longitudinal direction F.

In this embodiment, the moving tool 52 comprises a guide rail 53 laid on the upper frame member 41c of the support frame 41,
A movable table 54 which is engaged with the guide rail 53 and is movably guided at right angles to the length direction F;
And the rod end is formed from an advancing and retreating tool 55 such as a cylinder connected to the moving table 54 at the rod end.

In the present embodiment, the elevating and lowering tool 51 comprises a cylinder having a guide shaft 56 built therein, and is supported by the movable table 54 with its rod 51A directed downward.

As shown in an enlarged view in FIG. 10, the cutting tool 50 includes, for example, a U-shaped holding metal fitting 57 attached to the lower end of the rod 51A, a support shaft 59 supported by the holding metal fitting 57, and A plurality of the cutting blades 49 are detachably and rotatably supported on a support shaft 59.

The cutting blade 49 is a thin disk-shaped round blade, and is alternately arranged with the ring-shaped spacer 60 on the support shaft 5.
By extrapolating around the periphery of 9, they are arranged at intervals of the predetermined width. Both ends of the support shaft 59 are bearing pieces 61A,
It is exchangeably held on the side plate portions 57A, 57A of the holding metal fitting 57 via an end spacer 61B, a retaining ring 61C, and the like. The change of the cutting width and the number of ring bodies W1 formed by one cutting can be performed by changing the width of the spacer 60 and the number of the cutting blades 49 attached.

Here, the position of the cutting blade 49E on the most upstream side is changed by the change. Therefore, in this example, the reduced length of the rod of the one reciprocating tool 39A (shown in FIG. 4A) is configured to be adjustable using a stopper or the like. By adjusting the reduced length, the take-up position Y1 is adjusted to the position of the cutting blade 49E on the most upstream side.

As described above, in the cutting means 9 of this embodiment, as shown in FIGS. 8 and 9, the cutting tool 50 is located above the cutting table 6 and outside the holding tool 43 (left side in the figure). It waits at the steady position U1. When the tubular body W is pressed by the fixing means 7 and flattened, the cutting tool 50
Is lowered by the operation of the lifting / lowering tool 51 to the lowering position U1A where the cutting blade 49 contacts the upper surface of the cutting table 6. Thereafter, the moving tool 52 is operated, and the cutting blade 49 is moved to the gap G.
The tubular body W is cut by rolling to the transverse position U1B crossing the tubular body W through the inside.
For this purpose, in the present embodiment, the length of the pressing shaft 47, that is, the length L1 of the gap G is determined by the flat width L2 when the tubular body W is flatly crushed and the diameter L3 of the cutting blade 49. Is set to be larger than the sum L2 + L3.

Next, the overall operation of the cutting machine 100 of the present embodiment is conceptually schematically shown in FIGS. First, the chuck member 27 of the guiding means 5 moves from the standby position Z3 to the most upstream position Z1, and grips the distal end We of the tubular body W held at the receiving position Y1, and at the intermediate position Z2 in the gripped state. And stop (Fig. 11 (A)
-(C)). That is, the tubular body W at the receiving position Y1
To guide to the cutting position Y2.

With the chuck 27 holding the front end We, the presser 43A of the first fixing means 7A is lowered, and firstly, the upstream half of the cutting area is pressed flat and fixed. Next, after the chuck tool 27 releases the front end We and retreats to the standby position Z3, the pressing tool 43B of the second fixing means 7B descends and flatly presses and fixes the remaining downstream half area (FIG. 11 (D) to FIG.
(B)). As a result, the entire area to be cut can be fixed with high accuracy without displacement.

In this fixed state, the cutting tool 5 of the cutting means 9
0 descends from the standby position U1 to the descending position U1A, and in this descending state, the cutting blade 49 rolls through the gap G to the transverse position U1B and laterally moves.
The tubular body W is cut into a plurality of ring bodies W1 having a predetermined width (FIGS. 12B and 12C).

The cut ring body W1 is discharged out of the apparatus through the shooter 20 (shown in FIG. 1) as the cutting table 6 tilts around the pivot point J to the dispensing position X2 (see FIG. 1). FIG. 12 (D)).

Next, a second embodiment of the fixing means 7 is shown in FIGS. In the second embodiment, the fixing means 7
Includes one long holding member 43 for fixing the entire region of the cutting of the tubular body W, and a lifting member 70 for moving the holding member 43 up and down. And the lifting / lowering device 70 is
14A to 14D, the entire area of the cutting of the tubular body W is pressed against the cutting table 6 in a state where the tubular body W is gripped by the chuck 27 as shown in FIGS. After the chuck tool 27 releases the tubular body W and moves to the standby position Z3 in the temporarily fixed state, the cutting of the temporarily fixed tubular body W is performed. The entire area is lowered to two positions including a second lowering position P2 where the entire area is further pressed flat and fixed to the cutting table 6.

More specifically, the lifting / lowering device 70 is
As schematically shown in FIGS. 7A and 7B, a main lift 71 which is a cylinder for raising and lowering the presser 43, and sub-lifts 72 and 7 which are cylinders for regulating the rod stroke.
2 and the main and sub lifting devices 71 and 72 are supported by the mounting plate 44 in this example.

In the present embodiment, the main lifting / lowering device 71 is a cylinder with a built-in guide shaft 71A, and the holding device 43 is attached to each lower end of the rod 71a and the guide shaft 71A. Further, the guide shaft 71A is provided with the main lift 7
1, is inserted and protrudes upward, and at the upper end thereof is formed a contact portion 74 that contacts the stopper 73. In this example, the contact portion 74 is constituted by a connecting piece connecting the upper ends.

The sub-elevating tool 72 has a rod 72
a through hole 73A through which the guide shaft 71A passes
And a stopper 73 having the same.

Accordingly, the auxiliary lifting / lowering device 72 moves the stopper 73 downward to the standby position Q by the extension of the rod 72a.
It can move from 1 to the ascending position Q2.

The main lifting / lowering device 71 has its rod 71
By the extension of “a”, the presser 43 is lowered from the upper standby position R. At this time, the stopper 73 is in the raised position Q2.
In this case, the contact portion 74 comes into contact with the stopper 73, and the extension of the rod 71a is restrained.
Stops at the first descending position P1 where the tubular body W is temporarily fixed.

When the rod 72a of the auxiliary lifting / lowering device 72 is reduced and the stopper 73 is lowered to the lower standby position Q1, the restraint of the stopper 73 on the contact portion 74 is released, and the pressing device 43 is connected to the tube. The body W can be lowered to the second lowering position P2 for fixing the same.

Here, the temporary fixing means a state in which the tubular body W is pressed lightly so as not to move. Therefore, in this example, the spacer 75 is detachably attached between the stopper 73 and the contact portion 74 to adjust the first descending position P1. As shown in FIG. 15A, the spacer 75 has a U-shaped hole 75A that can be inserted into the guide shaft 71A from the side, thereby facilitating replacement. The spacer 75 can be fixed to the stopper 73 by, for example, a magnet, or a ball plunger 76 can be provided so as to be able to come and go as in this embodiment. Note that the spacer 75 may be divided into two as shown in FIG.

As described above, since the stop at the first lowering position P1 is possible, the first and second fixing means 7A and 7B can be stopped while avoiding interference with the chuck 27 in the gripped state.
As in the case of the fixing means 7 of the first embodiment, the entire region of the tubular body W can be fixed with high accuracy without displacement. Also, it is preferable that the pressing force at the time of fixing is a force for crushing the lumen of the tube-shaped body W and flattening it into a band shape as in the case of the first embodiment.
The working air pressure on the descending side is controlled by a precision pressure reducing valve.

In the first embodiment, the first and second
The stress on the tubular body W, which tends to occur near the boundary between the holding members 43A and 43B, can be prevented by the fixing means 7 of the second embodiment, so that the deformation of the cut surface due to the stress is suppressed. It is preferable in terms of quality improvement.

Although the preferred embodiment of the present invention has been described in detail above, the present invention is not limited to the illustrated embodiment, but can be implemented in various forms.

[0054]

Since the present invention is configured as described above,
The tubular body can be cut into a plurality of rings of a predetermined width continuously and efficiently with high accuracy without stopping the extruder.
