The specific embodiment

Preferred embodiment of the present invention will explain referring to accompanying drawing hereinafter.

In Fig. 1, be shown in the preferred embodiment of the present invention to the structural representation of the main portion of a bundled sheets processing apparatus 1 (following is the easy processing machine 1 that is called).Processing machine 1 receives the sheet material of a fixed number and pricks bundle t (being 100 sheet materials in the present embodiment), lamination utilizes a band K to tie up, from a preparative treatment machine 10 (arrow T1) and after checking the state of tying up with band K, transmit and prick bundle t to follow-up process (arrow T2).The direction of transfer of pricking bundle t be basically with a direction of the direction quadrature of sheet material lamination.In addition, in the present embodiment, only have a band be wrapped in direction of transfer on the position of trailing flank bevel of sheet material, and along the short direction of sheet material.

Processing machine 1 has a chute unit 2 (pricking the bundle receptor) to receive the bundle bundle t that is released at direction of arrow T1 by a push rod 11 of preparative treatment machine 10.Chute unit 2 has a chute 2a (first forwarder) and is tilted to down along following right; Here it is, the arrow T1 direction in Fig. 1 and receive along chute 2a by self weight and to prick bundle t.The bundle that chute unit 2 is placed and is included on the chute 2a along the sheet material stack direction is restrainted t.Moreover chute unit 2 receives a bundle bundle t who is arranged in a primary importance place state shown in Fig. 1 inside solid.

Along arrow T1 direction, a hill holder 4 is set at the end of chute unit 2, it has a mating surfaces 4a and is used to stop at one in the chute 2 and pricks bundle t, and at this moment the end by it withstands on direction of transfer along the surface of chute 2a.In the present embodiment, hill holder 4 moves by a screw actuator, sees aftermentioned for details, but it can integrally make with chute unit 2, for example makes a sheet material of flat-panel component.

Mating surfaces 4a partly relies on the transfer path of pricking bundle t thereby make on the narrow width of the thickness of pricking bundle 5 on the sheet material stack direction than one.Mating surfaces 4a is risen with almost right angle by the chute 2a of chute unit 2 significantly, with and highly be lower than a thickness of pricking bundle t.Therefore, when a band K who pricks bundle is loose, one prick in the bundle t some sheet materials might be not in mating surfaces 4a (in the present embodiment at several sheet materials) near the stack direction top of separating by chute 2a may prick bundle t by one and protrude.

Hill holder 4 has one and falls horizontal component, and inside mating surfaces 4a rises and a stop surfaces 4b on direction of transfer, near extending abreast with mating surfaces 4a.The function of stop surfaces 4b is to withstand stop surfaces 4b and stop a bundle bundle t by the end bump of pricking the sheet material of bundle t protrusion by one.Therefore, when sheet material protruded, the sheet material of protrusion had fully been avoided pricking bundle t by one and has been deviate from.

Hill holder 4 fall that horizontal component 4c makes a hole (not shown) so that an optic axis by a pathosis detector 6, its function is to be used for surveying as a detector protruding.When an end of pricking bundle t moved the mating surfaces 4a that withstands hill holder 4, pathosis detector 6 was surveyed and is pricked bundle t by one and protrude from sheet material outside the mating surfaces 4a.Here it is, and pathosis detector 6 is surveyed the protrusion when the crossing sheet material of the optic axis of the end of the sheet material that protrudes and pathosis detector 6.

In addition, on the chute 2a of chute unit 2, make a hole (not shown) and pass through it with the optic axis that allows a hold mode detector 8.Hold mode detector 8 is positioned at a position, and the state of chute unit 2 was to be adjusted to that the primary importance shown in the solid line and detection are conveyed into that of chute unit 2 pricks bundle t and by its discharging when its optic axis advanced by this hole herein.

Chute unit 2 is arranged to like this, and it can tilt versatilely to the center on an axle 2b.

Chute unit 2 is to rotate between the second place shown in the primary importance shown in the solid line and the dotted line in the drawings.In the present embodiment, be to be tilted on the different direction when chute unit 2 is adjusted in primary importance with the second place.Chute 2 by it self weight fall the next bundle bundle t that contains along with figure in the chute 2a of the second place bevelled state shown in the dotted line.And at this moment, prick bundle t for one to fall, and the rear end on direction of transfer is positioned at the front along direction of arrow T1.

Below chute unit 2, feed belt 14 that a belt conveyor 12 (second carrying device) belt conveyor 12 has an annular is set transmits roller 13 around one and twine, it is rotated by an electrical motor, sees below explanation.Feed belt 14 is pressed the T2 of the direction of arrow shown in figure running, releases an end (the back end on direction of transfer is as following explanation) of pricking bundle t and is fallen on direction of arrow T2 by chute unit 2.Here it is, when a bundle bundle t transmits on direction of arrow T2, twines one and prick the leading flank that a band K who restraints is positioned at direction of transfer.

A rubber roller 3 is shown in Fig. 2, and its function is as a pushing unit of the present invention.Rubber roller 3 is by a contact/separation device rotatably support.See below explanation, moreover, rubber roller 3 is provided with between the two positions: position is in the side that the squint surface 2a that pricks bundle t by that is received in chute unit 2 separates, thereby another position is to realize contact/separation separating on the direction of arrow S upwards to make to a state on the direction of arrow S that it might be shown in the figure.

Rubber roller 3 direction of arrow R shown in the figure go up by an electrical motor and rotate, and see below explanation, keep contacting with an end face of sheet material under this state.Therefore, the sheet material on the top and several sheet material that accompanies with it are pushed the stop surfaces 4b near hill holder 4.In other words, rubber roller 3 promotes the sheet material that can not contact with hill holder 4 (mating surfaces 4a) on direction of arrow T1.

And at this moment, several sheet materials near end face are promoted by the rotation of rubber roller 3, even these sheet materials do not protrude by pricking bundle t, only withstand the mating surfaces 4a of hill holder 4 when their operations, therefore and when a band is loose slightly, several sheet materials are forced to protrusion.

Here it is, when the detection accuracy of the bundle pencil attitude of restrainting t is pricked in one of hope raising, rubber roller 3 is set with operation.Yet rubber roller 3 is not requisite parts of the present invention.Usually, it only need be with an angle of inclination of the primary importance of regulating chute unit 2, thereby regulates the angle of the leaning angle of chute 2a a hope according to detection accuracy.

Fig. 3 illustrates a screw actuator 5, its function be as a moving device with mobile hill holder 4 and an interior guide 7a and an outer guide 7b, their both functions are to guide one to prick bundle t and advance by hill holder 4 near belt conveyor 12 as guide device.

Screw actuator 5 is mobile hill holder 4 between a stop position and bleed position.Stop position is such position, the mating surfaces 4a of hill holder 4 pricks on the transfer path of restrainting t at one herein, at this moment prick bundle t and transmit, and chute unit 2 is adjusted to primary importance (position shown in the dotted line in Fig. 3) by the chute 2a of it self weight along chute unit 2.Bleed position is such position, and mating surfaces 4a is bled by pricking bundle t transfer path upwards and allow one to prick bundle t and directly advance by chute unit 2 (position shown in Fig. 3 inside solid) herein.

Interior guide 7a is arranged on the end of chute unit 2, is arranged on primary importance with continuous position and attitude, and is crooked, thereby the end that makes one of guiding prick the direction of transfer of bundle t passes through chute unit 2 to belt conveyor 12.Moreover outer guide 7b is arranged on a position relative with interior guide, heads on its end of pricking the direction of transfer of bundle t and is withstood by 2 operations of chute unit, can not protrude under the effect of operation power thereby make.

When hill holder 4 be by Fig. 3 A in the stop position shown in the dotted line move to finding time during the position shown in the solid line, in chute unit 2 one pricks bundle t by two

guide

7a and 7b guiding and fall to belt conveyor 12.And at this moment, on direction of transfer one rear end of pricking bundle t is by being arranged on the optic axis of the hold mode detector 8 in the chute unit 2, and the output that will survey is as a binary pair, and the belt conveyor 12 that is in halted state brings into operation.This state at this moment is shown in Fig. 3 B.

When the end of a bundle bundle t contacted feed belt 14 on direction of transfer, a bundle on direction of transfer was restrainted the end of t owing to the friction with feed belt 14 is pushed out at direction of arrow T2, and can not change the direction of transfer (Fig. 3 D) of a bundle bundle t.Here it is, restraints t when direction of arrow T2 transmits when a bundle, ties up one and prick the end profile that a band K who restraints t is positioned at direction of transfer.

In addition, the function of screw actuator 5 is as a moving device, with mobile hill holder 4 with as the interior guide 7a of guide device and outer guide 7b, it can be provided with independently and not provide a mechanism to rotate chute unit 2 illustrated in figures 1 and 2, and perhaps one can provide with screw actuator 5 and interior and

outer guide

7a and 7b in combination in order to the mechanism that rotates chute unit 2 illustrated in figures 1 and 2.

When hope changes the direction of transfer of a bundle bundle t of lamination in chute unit 2, in having the equipment that a mechanism and screw actuator 5 and interior and outer guiding

tube

7a and 7b rotate the chute unit in combination, it might be changed a bundle bundle t and return, at this moment by the second place of rotating in the state of chute unit 2 when hill holder 4 is arranged in stop position, shown in the dotted line of Fig. 3 A.On the other hand, when not wishing to change the direction of transfer of a bundle bundle t of lamination in chute unit 2, prick bundle t for one and can pass through, and at this moment by arranging hill holder 4 at bleed position, shown in solid line, and guide to belt conveyor 12 by two

guide

7a and 7b.

Fig. 4 is a block scheme, and the control system of the control operation of bundled sheets processing apparatus 1 is shown.

The operation of its control processing machine 1 of a CPU20 (treater) is connected with hold mode detector 8 with above-mentioned pathosis detector 6.In addition, 23, one screw actuators 5 of 22, one electrical motors of 21, one contact/separation devices of an electrical motor and an electrical motor 25 are connected to CPU20.

Electrical motor 21 rotates chute unit 2 between first and second positions.Contact/separation device 22 moves rubber roller 3 at direction of arrow S.Electrical motor 23 is at the moment of torsion rotation rubber roller 3 of direction of arrow R with a regulation.Screw actuator 5 is mobile hill holder 4 between stop position and bleed position.Electrical motor 25 is at direction of arrow T2 running belt conveyor 12.

The CPU20 of processing machine 1 is connected with the CPU30 of preparative treatment machine 10.The CPU30 of preparative treatment machine 10 is connected with a band detector 31, be used for surveying a direction of pricking bundle t by the winding position of surveying band K, and a transfer bar mechanism 32 is used to operate push rod 11.Photo pricking bundle t of band detector 31 picked-ups, and the position of surveying band K according to the CF of the band K on the image of picked-up photo.A band K is wrapped in a vertical last single side face position of pricking bundle t; Here it is, direction of transfer, and therefore a direction of pricking bundle t can be detected, at this moment by the winding position of surveying band K.

In addition, above-mentioned CPU20, chute unit 2 (chute 2a), and hill holder 4 (mating surfaces 4a and stop surfaces 4b), the function of pathosis detector 6 and rubber roller 3 is the parts as bundled sheets processing apparatus.

Below, in the processing machine 1 of above-mentioned structure, prick the manufacturing procedure of bundle t and will explain referring to a diagram of circuit shown in Figure 5.Moreover, state to start with, chute unit 2 is arranged in primary importance, wait for that receiving one pricks bundle t, and hill holder 4 is arranged in stop position.

Before operation, a direction of pricking bundle t is surveyed by the band detector 31 of preparative treatment machine 10, notifies to the CPU20 of processing machine 1.Here it is, and a direction of pricking bundle t is to survey according to the winding position of the band K that surveys with band detector 31.In the present embodiment, only when a bundle bundle was wrapped in position of the single side face on the side, rear end in the direction of transfer with a band K, its transmitted and enters chute unit 2, as shown in Figure 1, a bundle bundle t is converted and returns, at this moment by the second place shown in tip chute unit 2 to Fig. 1 dotted lines.Here it is, and the bundle bundle t that advances by processing machine 1 all is sent to follow-up procedure of processing, and the end of the bundle bundle of the side of twining with band in front.

CPU20 judges whether a bundle bundle t who prepares processing was in correct direction before being sent out by preparative treatment machine 10, judgement is the notice (step 1) according to the CPU30 of preparative treatment machine 10.In sent out the present embodiment of pricking bundle t by preparative treatment machine 10, the attitude (attitude in Fig. 1) that is wrapped in the bundle bundle t of a position of the single side face on the side, rear end in the direction of transfer with a band is judged as correct direction.When bundle bundle in step S1 is judged as correct direction (step S1; YES), then pricking bundle t transmits by 10 dischargings (step S2) of preparative treatment machine and by the push rod 11 of preparative treatment machine 10 and enters chute unit 2.And at this moment, 2 interior reception held state detectors 8 of pricking bundle t are surveyed in the chute unit, and notice (step S3).Whether an end of pricking bundle t moves the mating surfaces 4a that withstands hill holder 4 on direction of transfer subsequently, judges by pathosis detector 6, have sheet material to protrude (step 4) by pricking bundle.And at this moment, when part sheet material was surveyed by pathosis detector 6 by the protrusion of a bundle bundle, the inferior-quality state of tying up of pricking bundle t was judged (step 4; NO).When the output of pathosis detector 6 is eliminated, if do not surveyed by pathosis detector 6 by a sheet material of pricking the protrusion of bundle t, the state of tying up of pricking bundle is judged as well (step 4; YES).Chute unit 2 is turned to the second place by electrical motor 21 under this state, and (step 5) and a bundle bundle t fall to belt conveyor 12, shown in the dotted line of Fig. 1 to make hill holder 4 be arranged in stop position.

Subsequently, do not prick bundle t (step S6) when hold mode detector 8 detects in chute unit 2, electrical motor 25 rotates and the operation of belt conveyor 12 begins (step S7).Fall at one on the belt conveyor 12 bundle bundle t and on direction of arrow T2, transmit; Here it is, to next procedure, under this state and make a band be positioned at the top, pricks bundle to transmit one.After this, chute unit 2 is rotated and is back to primary importance by electrical motor 21, shown in Fig. 1 inside solid.On the other hand, be judged as nonconformity (step S4 in step S4 when the state of tying up; NO), the electrical motor 21 of chute unit 2 does not drive with processing machine 1 and preparative treatment machine 10 and jointly stops (step S8).Here it is, and CPU20 exports a signal, and the bundle bundle that inferior-quality band of expression pathosis detector 6 detections is tied up is to stop processing machine 1.When processing machine 1 stopped, a door (not shown) of processing machine 1 was opened (step S9).And the bundle bundle t that inferior-quality band is tied up is taken out (step S10) by an operator by processing machine 1.

Moreover, when a bundle bundle is judged as not (step 1 on correct direction by band detector 31; NO), carry out and of the processing of above-described step 2 to the identical step S2 ' of step 4 to step S4 '.Subsequently, the state of tying up of pricking bundle t at step S4 ' be judged as nonconformity (step S4 '; NO) process is transferred to the process of step S8 to step S10.

Moreover when a direction of pricking bundle t is judged as mal in step S1, but the state of tying up is in step 4 ' in be judged as good (step 4 '; YES), hill holder 4 is moved to bleed position, (step 11) as shown in Fig. 3 A by screw actuator.When hill holder 4 moves to bleed position, prick bundle t for one in chute unit 2 and guide to belt conveyor 12, shown in Fig. 3 B and Fig. 3 C by hill holder 4 and by two

guide

7a and 7b.

Afterwards, prick bundle and be present in held state detector 8 detections (step S12) in the chute unit 2, electrical motor 25 drives and belt conveyor 12 brings into operation (step S13).A bundle bundle t who guides to belt conveyor 12 transmits on direction of arrow T2; Here it is, to next procedure, under this state and make a band K be positioned at a head side of pricking bundle t.After this, hill holder 4 is returned to stop position by screw actuator 5.

As previously discussed, according to present embodiment, prick bundle t for one and transmit along chute 2a with it self weight and enter chute unit 2 and meanwhile, the state of tying up of pricking bundle t can be detected.After this, can change by the direction of transfer that selectively rotates chute unit 2, one bundle bundles t.Here it is, and the structure of checking the state of tying up to use can partly be used as changing and prick the structure that bundle t direction is used.Therefore, the structure of equipment can be simplified and the manufacturing expense of equipment can reduce.

Moreover, according to present embodiment, clash into some sheet materials of mating surfaces 4a that withstand hill holder 4 by the end of a bundle bundle t on direction of transfer and be forced to protrusion, and therefore the state of tying up of a band K can more properly be verified.And when the testing accuracy of tying up state wished to improve, it was enough operating rubber roller 3 shown in Figure 2.Therefore, it is loose that state of tying up of pricking bundle t can be avoided becoming, and when transmitting in the procedure of processing in the back, falls and can be avoided reliably as loose result and the sheet material of a band K.

Below, the bundled sheets processing apparatus 50 (abbreviating processing machine 50 hereinafter as) among other the embodiment of the present invention will be explained referring to Fig. 6 to 8.In addition, will represent with identical figure number with parts similarly identical on the function of above-described processing machine 1, with and detailed explanation omit herein.Fig. 6 illustrates a transparent view of processing machine 50.Fig. 7 illustrates its front elevation, and Fig. 8 illustrates its lateral plan.

In other words, processing machine 50 has a holding element 52 near hill holder 4, and the end of a bundle bundle on direction of transfer that transmits along chute 21 withstands it, with the sheet material that is protruded by mating surfaces 4a on the direction that remains on the sheet material lamination.Holding element 52 is made up of one group of panel element, and they are separated from one another along a Width of pricking bundle t, and are fixed to chute unit 2.Here it is, and processing machine 50 in the present embodiment is structures, is used to change return whole bundle bundle t, and it does not have structure to be used for bleeding of hill holder 4, explain like that as Fig. 3, and so hill holder 4 and holding element 52 be to be fixed to chute unit 2.Moreover chute unit 2 is bevelleds between described in the above first and second positions, at this moment by the cam follower 61 of a turning cylinder that is fixed to electrical motor 21 be fixed to the effect of a cam 62 of the lower surface side of chute unit 2.

In more detail, holding element 52 has a bevelled guiding surface 52a, pricks sheet material (not shown) outside the mating surfaces 4a that bundle t protrudes from hill holder 4 to stop surface 4b with guiding by one.In other words, contact with a part of pricking bundle before and then the guiding surface 52a of each holding element 52 contacts with mating surfaces 4a, and the end that transmits the sheet material of contact; Here it is, protrudes the sheet material that surpasses mating surfaces and be sent to stop surfaces 4b.

Therefore, protrude from sheet material outside the mating surfaces 4a of hill holder 4 and avoided swing on stack direction, and avoided pricking falling fully truly of bundle by one.

In addition, the present invention is not limited to above-described embodiment, but can make various changes within the scope of the invention.For example, in the above-described embodiment, a kind of situation of explanation is by electrical motor 21 chute unit 2 to be tilted, but is not limited to this, and chute unit 2 also can not use driver train and by it own wt and tilt, as shown in Figure 9.

Here it is, axle 2b can be arranged in the chute unit 2, contain within it thereby make chute unit 2 can tilt to the primary importance shown in the solid line and under this state, do not prick bundle t, and tilt to the second place shown in the dotted line, and contain within it at the next bundle t that pricks of this state.In other words, axle 2b can be arranged as such location, making and restrainting t when a bundle is not when being included in the chute unit 2, the center of gravity of chute unit 2 is positioned at the side of the hill holder 4 that leaves a 2b, and when one to prick bundle be when containing within it, the center of gravity of chute unit 2 is positioned at the side of the preparative treatment machine 10 that leaves a 2b.

Therefore, rotate the driver train of chute unit 2 and can cancel, and the structure of equipment can further be simplified.Moreover in the present embodiment, a return spring is arranged on chute unit 2, in order to return chute unit 2 positively to primary importance.

Moreover in the described in the above present embodiment, a kind of situation of explanation is that the sheet material that survey to protrude is by pricking bundle t and bump withstands hill holder vertically transmitting one.Yet, should not be limited to this kind situation, to prick bundle t be during almost with the stack direction quadrature of sheet material when one, it can transmit on short direction.

Under any circumstance, it is enough to clash into and has loose of tying up of band and prick the bunchy top and live hill holder, thereby some sheet materials are protruded by pricking bundle.

Moreover in the above-described embodiment, surveying by a sheet material of pricking the bundle protrusion is that an end of pricking bundle withstands hill holder on the direction of transfer by partly impinging upon, and it is by a quantity of pricking a regulation of transmission rat of bundle.Yet, should not be limited to this kind situation, the mating surfaces of hill holder can be arranged on and leave a position of transmitting the surface, at this moment considers thickness of pricking bundle on the sheet material stack direction.In such cases, be detected near the side of transmitting the surface by a sheet material of pricking the bundle protrusion.Here it is, can be detected by a sheet material part of pricking the lower surface side protrusion of bundle t.

Moreover in the above-described embodiment, a kind of situation is when being received one by preparative treatment machine 10 when pricking bundle, makes one to prick bundle and use it self weight to transmit along chute 2a by tip chute unit 2 to primary importance.Yet, should not be limited to this kind situation, chute unit 2 is arranged as almost level and another connecting gear can be set.

As explained above, according to the job operation of the Fabricating machinery and a bundled sheets of a bundled sheets of the present invention, the state of tying up of the sheet material of tying up can be checked reliably, prick the distortion of bundle attitude and can avoid, and dropping out of sheet material can be avoided.
