But, in above-mentioned existing boxing apparatus, have problem as follows.

That is to say, in the above-mentioned existing boxing apparatus of article that the corrugated sheet carton is packed into constant direction (vertically), the space that produces for size owing to corrugated sheet carton and article, though for example can not to the corrugated sheet carton with vertical vanning but so long as the space that laterally just can case article can not be cased.And in such vanning process, the posture of columns of items is mixed and disorderly or the charging efficiency of the posture of the columns of items article of being cased when irregular reduces when the conveying in columns of items.

Summary of the invention

Problem of the present invention just provides a kind of direction that can change the article of packing into for the peristome of corrugated sheet carton, also can be with the feedway and the boxing apparatus that comprises this feedway of article vanning to aforesaid space even make.And, while problem of the present invention also is to make the articles conveyed row of posture that do not destroy the posture of columns of items and rectify columns of items in the course of conveying of the columns of items that is boxed to improve the charging efficiency of vanning.

The feedway of a first aspect of the present invention, the article that will accept one by one from the outside gather and form article group, and this article group is carried, and this device comprises transfering department, mounting portion and control part.Wherein, transfering department, it rotates to erecting posture state and shifts and article are erected after having accepted article, and transfering department downstream side with putting article.Mounting portion, the article that passed on by transfering department of mounting successively form and are in the article group of gathering state; Control part, it is according to desirable passing at interval when gathering form changing transfering department to the mounting portion that moves handling objects successively on throughput direction.

At this,, changed the form of gathering of article group (one group of commodity of queuing) by changing and control transfering department passing at interval during to the mounting portion that on throughput direction, moves handling objects successively.

Pass at interval in this what is called, refer to from transfering department to mounting portion handling objects pass on the position, the described position of passing on is adjacent and be positioned in distance on the throughput direction between the upstream-side-end of article in its downstream with neutralizing in mounting portion.In addition, the desirable state that gathers, for example have to make the form of gathering before and after on the throughput direction towards the article of vertical direction roughly of the area maximum of article, i.e. flat condition to gather with arranging with respect to the stable status of the mounting portion that on throughput direction, moves, arrange before and after on the throughput direction and make that on throughput direction the part of adjacent article is overlappingly gathered, what is called is tiltedly put state, similar but with the above-mentioned form of tiltedly putting to erect the state etc. that stands up that posture is gathered with arranging before and after throughput direction.

In existing boxing apparatus, for example with many article to stand up posture and line up in the horizontal direction and to form article group, on vertical direction, change it with respect to peristome pushing the position and above-mentioned article group is pushed towards the corrugated sheet carton of horizontal direction.Yet, owing to the orientation of one group of such commodity can only be lined up with equidirectional usually, so also can only case with equidirectional.

Therefore, in feedway of the present invention, control part changes at interval passing on, and described passing on is from transfering department passing at interval when the mounting portion that moves at throughput direction handling objects successively at interval.

Thus, can line up with different gestures, change the form of gathering of article group according to passing on the article that will accept one by one at interval from the outside.For example, if fully guarantee to pass at interval, owing to be transferred to article in the mounting portion posture that erects when passing on the position and overturn and fall down to become the state that keeps flat passing on, so can form the form of gathering as flat condition.And for example passing under the at interval not enough situation since pass on be transferred on the position article in the mounting portion be in lean against previous by the state on the article of mounting, so erect posture can keep passing on the time.In the case, can form to erect the form that stands up that posture gathers before and after on throughput direction with arranging.

The result, can pass on by control and form the desirable form of gathering at interval, for example the different position on vertical direction that the different article group of form pushes the peristome of corrugated sheet carton of gathering by forming as mentioned above can change the direction of the commodity of vanning with respect to corrugated sheet carton peristome.

When commodity X when the shovel 122 of upstream side is transferred, the bucket of waiting in the downstream 141 as shown in Figure 4, the interval of side shifting regulation (passing at interval) downstream (below be expressed as pass at interval) CL, mounting is from shoveling the 122 commodity X that pass on.In addition, pass at interval CL, can change the queueing condition of the group of article X, promptly gather form, this is described in detail in the back by change.Below, commodity X is described with the situation that the state that can keep erecting posture is positioned in the bucket 141.

Next, when mounting regulation number from commodity X that upstream side passes on the time, bucket 141 keeps erecting posture is transported to the downstream along throughput direction b drain position R with the groups of commodity X.At this moment, as shown in fig. 1, the bucket of waiting for the adjacent ground connection of upstream side of bucket 141 throughput direction b 142 is side shifting downstream promptly, similarly accepts commodity X to erect posture successively from shoveling 122 with above-mentioned bucket 141.

As shown in fig. 1, in bucket 141,142, be configured to a plurality of base plate 141a, 142a, from upstream side to the downstream angle tilt with regulation, make that base plate 141a, the 142a in downstream are higher when carrying commodity X.Therefore, the base plate 142a in bucket 142 downstream can overlap on the base plate 141a of upstream side of bucket 141 with partly overlapping state.

Thus, bucket 142 is owing to can so can promptly move to the downstream of throughput direction b when the drain position R of side moves downstream at bucket 141, accept commodity X from upstream side at the more approaching location pending that passes on position Q.In addition, bucket 141 can partially overlap on the base plate 142a of bucket 142 upstream side too.

Then, when will be to erect group that posture is positioned in the commodity X of bucket in 141 when discharging by the output mechanism 150 that is described in detail later, bucket 141 further moving on the direction of throughput direction b on the conveying mechanism 140.Then, bucket 141 is waited for around move, move to the upstream side that is right after 142 the throughput direction b of struggling against on the direction opposite with throughput direction b to the bottom of conveying mechanism 140 always when the end in the downstream that moves to conveying mechanism 140.Then, when bucket 142 is accepted the commodity X of regulation number and when shifting to drain position R, bucket 141 moves to the downstream of throughput direction b rapidly from upstream side, with the above-mentioned commodity X that similarly accepts to stipulate number successively from upstream side.

(structure of output mechanism 150)

As shown in Figure 3, the adjacent ground connection configuration of output mechanism 150 with the downstream of above-mentioned conveying mechanism 140, to be transported to drain position R and with the group of the commodity X that erects posture queuing by conveying mechanism 140, the alongside transfer by two steps pushes among the corrugated sheet carton Y.Output mechanism 150 has the first alongside transfer mechanism 151, the second alongside transfer mechanism 152 and lift system 153 as shown in Figure 5.

The first alongside transfer mechanism 151, the group that will move to the commodity X of drain position R in above-mentioned conveying mechanism 140 is carried out alongside transfer on the arrow c direction shown in Fig. 3, be transported on the lift system 153.

Lift system 153 will roughly moved to the position that can be carried out the height of alongside transfer by the second alongside transfer mechanism 152 on the vertical direction by the group of the first alongside transfer mechanism 151 from a plurality of commodity X of conveying mechanism 140 alongside transfers as shown in Figure 5.

The second alongside transfer mechanism 152 is configured in the upper strata of the first alongside transfer mechanism 151, and the group of the commodity X that will be lifted by the lift system of narrating later 153 pushes in corrugated sheet carton Y from lift system 153 and to case.

Boxing apparatus 100 in the present embodiment will change on vertical direction to the position of moving into of corrugated sheet carton Y by the limit, Yi Bian carry out the action of aforesaid output mechanism 150 repeatedly, the state that can become multilayer to take in the commodity assembling box.

[pass on the at interval explanation of the switching controls of CL]

The following describes by what control part 149 carried out commodity X is transferred to the switching controls of CL at interval of passing on that struggled against at 141,142 o'clock from shoveling 122.

What is called is passed at interval CL, refer to pass on position Q and pass on position Q in bucket 141,142 neutralizations adjacent and be positioned in the distance on throughput direction between the upstream-side-end of commodity X in its downstream, in the time of in being illustrated in Fig. 4, Fig. 7 and Figure 10, CL1, CL2 and CL3 are respectively that this passes at interval CL.

In the boxing apparatus 100 of present embodiment, 149 pairs of the control parts intermittent delivery amount when shoveling 122 the intermittent delivery of bucket 141,142 when accepting commodity X is controlled, in other words, the fed distance that bucket 141,142 conveyer chain 143,144 is installed by control changes and passes on CL at interval.

The following describes the kind (stand up form, keep flat form and tiltedly put form) of gathering form and pass on the relation between the CL at interval.

(standing up form)

What is called stands up form, refers to as shown in Figure 4, makes to erect posture still to line up successively and be positioned in state on the bucket 141,142 to erect posture from shoveling the 22 commodity X that accept.

In the boxing apparatus 100 of present embodiment, the CL1 at interval of passing on that will be used to realize to stand up form is taken as only about half of (CL1=t1/2) of the length of commodity X on throughput direction that erects posture.

As present embodiment, commodity X has when the shape that the flexible packing material that grabs a bite for a short time forms is housed, and is the length on the throughput direction of the commodity X that erects posture, as shown in Figure 6, refers to the thickness t 1 of thickness largest portion.At this, according to passing on the at interval definition of CL, CL1=t1/2, but pass on position Q and the distance that is transferred to the center of commodity X on throughput direction in the previous bucket 141,142, be equivalent to the thickness t 1 of commodity X.

In the case, passing on the Q of position, as shown in Figure 6, do not destroy posture ground and still do not lean against on the previous commodity X2 with the state that erects from shoveling the 122 commodity X1 that pass on.Can form thus to make and be in the tandem form of gathering that stands up form of commodity X (X1, X2....) that erects posture when passing on.

(keeping flat form)

What is called keeps flat form, as shown in Figure 7, refer to the area maximum that makes commodity X towards the state of vertical direction roughly, promptly before and after on the throughput direction, arrange the state of ground mounting on bucket 141,142 with so-called flat condition.At this moment, with the length direction of commodity X towards throughput direction, still towards the orientation independent vertical with throughput direction.

In the boxing apparatus 100 of present embodiment, to be used to realize keep flat the CL2 at interval that passes on of form, be taken as (CL2 〉=t2) more than or equal to the length t2 of these commodity X under the state that is transferred to overturnings after the bucket 141,142 at the commodity X that erects posture on throughput direction.As described in present embodiment, commodity X has when the shape that the flexible packing material that grabs a bite for a short time forms is housed, and is the length of commodity X on throughput direction of the posture of falling, and is meant the t2 as shown in Fig. 8 (a).

In the case,, as shown in Fig. 8 (b), do not contact, so the result becomes the state that promptly fell with respect to bucket 141, the 142 the most stable situations that move with previous commodity X2 by mounting passing on position Q from shoveling the 122 commodity X1 that pass on.And, mounting has the rotation track of the shovel 122 of commodity X, as shown in Figure 14, the end of bucket side is in that to pass on position Q almost motionless, end with bucket side opposition side, direct of travel (i direction) at bucket moves and the release commodity, so the upper end side that is the commodity X that erects posture is stably overturn with respect to the direct of travel that struggles against.Thus, pass on the locational commodity X that erects posture, can form the tandem form of gathering that keeps flat form of commodity X (X1, X2......) that makes the state that was fallen in arrow g direction (with reference to Fig. 8 (b)) upset.

And, in the boxing apparatus 100 of present embodiment, pass at interval by the at interval scope adjustment of CL2 of passing on that CL has increased the variation kind of gathering form in regulation as implied above.That is to say,, for example, shown in Fig. 9 (a) and (b), can be increased in the metamorphosis kind that keeps flat in gathering by adjusting amount of space S1, the S2 that mounting becomes the commodity X (X1, X2....) of flat condition.

(tiltedly putting form)

What is called is tiltedly put form, as shown in Figure 10, refers to the state of arranging and gathering before and after a part that makes adjacent commodity X on the throughput direction is overlappingly on throughput direction.At this moment, with length direction towards throughput direction, still towards the orientation independent vertical with throughput direction.

In the boxing apparatus 100 of present embodiment, will be used to realize tiltedly put the CL3 at interval that passes on of form, be taken as (CL3＜t3) less than the length t3 of commodity X under the state that is transferred to bucket 141,142 back overturnings at the commodity X that erects posture on throughput direction.As described in present embodiment, commodity X has when the shape that the flexible packing material that grabs a bite for a short time forms is housed, and is the length on the throughput direction of commodity X of overturning posture, refers to the t3 as shown in Figure 11 (a).

In the case, passing on position Q, do not contacting, so in direction (with reference to Figure 11 (the b)) overturning of arrow h with the commodity X2 of previous institute mounting from shoveling the 122 commodity X1 that pass on.But as shown in Figure 11 (b), commodity X1 does not have overturning to becoming above-mentioned flat condition, but becomes the state overlapping with the part of previous commodity X2.And, mounting have commodity X shovel 122 rotation track as shown in Figure 14, the end of bucket side is in that to pass on position Q almost motionless, end with bucket side opposition side, direct of travel (i direction) to bucket moves and the release commodity, so the upper end side that is the commodity X that erects posture is stably overturn with respect to the direct of travel that struggles against.Thus, the commodity X (X1, X2......) before and after can forming each other with the overlapping state of a part tandem, so-called tiltedly put gather state.

And in the boxing apparatus 100 of present embodiment, CL carries out various adjustment to passing at interval by the scope of CL3 at interval of passing in regulation as implied above, has increased the variation kind of gathering form.That is to say,, for example, as shown in Figure 12 (a) and (b), can increase and tiltedly put the metamorphosis kind of gathering by adjusting lap L1, L2 with the commodity X (X1, X2......) of tiltedly putting the state mounting.

At boxing apparatus 100 as present embodiment, end at bucket 141,142 upstream side is respectively equipped with under the situation of dividing plate 141b, 142b, the distance of first (the file leader of throughput direction) commodity X of group by controlling this dividing plate 141b, 142b and formation commodity X can further increase the variation kind of aggregation method.Thus, for example, tiltedly put under the situation of form in realization, as shown in Figure 10, the mode that can rest on dividing plate 141b, the 142b with the top commodity X of the group that will form commodity X is gathered, perhaps as shown in Figure 11 (a) and (b), with the state aggregation with the complete overturning of top commodity X.

[explanation of casing with output mechanism 150]

In the boxing apparatus 100 of present embodiment, as implied above, realize the diversified form of gathering at interval by in conveying mechanism 140, controlling to pass on, can change direction with respect to the vanning commodity X of corrugated sheet carton peristome.

For example, the group that will be agglomerated into the commodity X of the state that stands up form by output mechanism 150 is cased, the group that will be agglomerated into the commodity X of the state that stands up form equally by output mechanism 150 is cased afterwards, the group that will be agglomerated into the commodity X of the state that keeps flat form by output mechanism 150 is cased then, can carry out the vanning of commodity X as shown in Figure 13 to corrugated sheet carton Y.

[feature of boxing apparatus 100]

(1)

The boxing apparatus 100 of present embodiment as shown in Fig. 4, Fig. 7 and Figure 10, according to the desirable state that gathers, changes from shoveling 122 and pass on CL at interval when bucket 141,142 passes on commodity X.

Thus, can be with the commodity X that accepts one by one from the outside with different posture queuings, and with the group of commodity X gather form change into keep flat form, tiltedly put form, stand up form etc.

As a result, can pass at interval that CL easily forms the desirable form of gathering by change, the peristome that can push corrugated sheet carton Y by the group of the commodity X that will so form changes the direction of vanning commodity X.

(2)

In the boxing apparatus 100 of present embodiment, with respect to the shovel 122 that rotates with constant speed, 149 pairs of handovers of control part are accepted the fed distance of conveyer chain 143 of the bucket 141,142 of commodity X side and are controlled.Specifically, the fed distance of control conveyer chain 143, make from shovel 122 accepted commodity X to accept till the next commodity X, the miles of relative movement of bucket 141,142 on throughput direction b for gather form (keep flat form, tiltedly put form or stand up form) pass on CL at interval accordingly.

Thus, can guarantee and gather form and pass at interval CL (CL1, CL2, CL3) accordingly.

(3)

In the boxing apparatus 100 of present embodiment, as shown in Figure 4, the CL1 at interval of passing on that will be used to realize to stand up form is taken as only about half of (CL1=t1/2) of the length of commodity X on throughput direction that erects posture.

Thus, passing on position Q,, as shown in Figure 6, do not destroying the posture that erects and still lean against on the previous commodity X2 with the state that erects from shoveling the 122 commodity X1 that pass on.Thus, can form and when passing on, to be the tandem form of gathering that stands up form of commodity X (X1, X2.....) that erects posture.

As a result, can form with lean against on the previous commodity X state and with the form of gathering of standing up of arranging of the state of overturning hardly.

(4)

In the boxing apparatus 100 of present embodiment, as shown in Figure 7, the CL2 that passes at interval that will be used to realize to keep flat form is taken as more than or equal to be transferred to bucket 141,142 and the length t2 on the throughput direction of its commodity X under the state of throughput direction overturning (CL2 〉=t2) at the commodity X that erects posture.

Thus, passing on position Q,, as shown in Fig. 8 (b), do not contacting, so it is the state of complete overturning that the result becomes with respect to bucket 141, the 142 the most stable situations that move with the commodity X2 of previous institute mounting from shoveling the 122 commodity X1 that pass on.As a result, can form will be when passing on erect the posture upset and the tandem form of gathering that keeps flat form of commodity X of the flat condition of falling.

(5)

In the boxing apparatus 100 of present embodiment, as shown in Figure 10, the CL3 at interval of passing on that will be used to realize tiltedly to put form is taken as less than being transferred to bucket 141,142 at the commodity X that erects posture and the length t3 of commodity X on throughput direction (CL3＜t3) under the state of overturning on the throughput direction.

Thus, passing on position Q, do not contacting, so fell in the direction (with reference to Figure 11 (b)) of arrow h with the commodity X2 of previous institute mounting from shoveling the 122 commodity X1 that pass on.But commodity X1 is as shown in Figure 11 (b), and not going over to becomes above-mentioned flat condition, but is in the state overlapping with the part of previous commodity X2.

As a result, just can form with tandem with the overlapping state of the part of previous article, so-called tiltedly put gather form.

(6)

In the boxing apparatus 100 of present embodiment, keeping flat under the form, pass on CL at interval by in above-mentioned scope of passing on CL2 at interval, adjusting, increased the variation kind of gathering form.That is to say that amount of space S1, the S2 of the commodity X (X1, X2.....) by being adjusted at mounting under the flat condition as shown in Fig. 9 (a) and (b), can increase the variation kind that keeps flat the form of gathering.

Tiltedly putting in the form, passing on CL at interval, increasing the variation kind of gathering form by in above-mentioned scope of passing on CL3 at interval, adjusting.That is to say,, as shown in Figure 12 (a) and (b), increased the variation kind of tiltedly putting the form of gathering by being adjusted at lap L1, the L2 of the commodity X (X1, X2......) of tiltedly putting mounting under the state.

(7)

In the boxing apparatus 100 of present embodiment, mounting has the rotation track of the shovel 122 of commodity X, and as shown in Figure 14, the end that forms the bucket side is gone up at the direct of travel (i direction) of bucket with the end of bucket side opposition side and moved in that to pass on position Q almost motionless.

Thus, shovel 122 promotes the upper end side of commodity X, can make to be the commodity X upper end side that erects posture and stably to overturn with respect to the direct of travel of bucket.

(8)

In the boxing apparatus 100 of present embodiment, shovel 122 is that the center rotates about 90 ° on the direction of hand of rotation e with S. A. 122a, moves in the position of P2 shown in Fig. 1, commodity X is become erect posture.At this moment, be approximately 90 ° at the shovel 122 of P2 (pass on position Q) with respect to the angle of horizontal direction.

Thus, because commodity X leaves shovel 122 reliably, so can reliably commodity X be passed on to bucket 141,142.

[conveying mechanism 40]

Conveying mechanism 40, as shown in Figure 21, Figure 23 and Figure 24, have a plurality of buckets 41,42, dividing plate 43a, 43b, backboard 44a, 44b and drive motor M1～M3, accept successively from the transfer device 20 of upstream side with erect posture be transported to Figure 21 assigned position Q article M and with the number of each regulation downstream the position R of side carry.

In Figure 24, upstream side and downstream that bucket 41,42 is separately positioned on conveying mechanism 40, along lodge with S. A. 45,46 be between center the sprocket wheel s1 and s1 that rotate, chain between s2 and the s2 moves in the form of a ring.And the bucket 41,42 of Figure 21 is transported to the position R in downstream with the columns of items ML that the mounting group by a plurality of article M thereon constitutes from the assigned position P of upstream side.And bucket 41,42 makes up a plurality of base plate 41a, 42a respectively and constitutes.Base plate 41a, 42a constitute the areal of support of the bottom Mb of supports articles M.

Dividing plate 43a, 43b are installed in respectively on base plate 41a, the 42a that is configured in downstream (file leader's side) among a plurality of base plate 41a, the 42a.The file leader's of the columns of items ML that passed on from transfer table 22 article M still can be remained by this dividing plate 43a, 43b and to erect posture, and make a plurality of article M queuing on each bucket 41,42 of after this passing on.In addition, dividing plate 43a, 43b are driven respectively by sprocket wheel s1, s2 independently by drive motor M1, the M2 (Figure 23) that narrate below.In addition, as shown in Figure 17, dividing plate 43a, 43b are constituted as, with the face of article M butt be the broach shape, can and not contact mutually with the comb-tooth-like portion clutch of above-mentioned transfer table 22.

As shown in Figure 21 backboard 44a, 44b are the parts that are positioned in the columns of items ML on 41,42 that respectively struggles against from rear supporting, respectively each dividing plate 43a, 43b are provided with.In addition, backboard 44a, 44b are installed on the position of putting toward each other in mobile loop by driving as common drive source drives motor M 3 (Figure 23).So, by backboard 44a, 44b are driven by the drive source different with dividing plate 43a, 43b, even under the altered situation of quantity of the article M of the stated number that is boxed, also can between dividing plate 43a, 43b, clip columns of items ML and columns of items ML is transported to drain position R with stable status.Backboard 44a, 44b are constituted as, with the face of article M butt be the broach shape, can and not contact each other with the comb-tooth-like portion clutch of above-mentioned transfer table 22, this point and dividing plate 43a, 43b are same.

Sprocket wheel s1～s3 of Figure 23 is configured in the two end portions of conveying mechanism 40 respectively, has same diameter.Thus, dividing plate 43a, dividing plate 43b, backboard 44a, 44b are moved with identical revolution and with identical speed.

In the present embodiment, as mentioned above, constitute and drive dividing plate 43a, dividing plate 43b, backboard 44a, 44b respectively independently, form first loop by the drive motor M1 that drives dividing plate 43a, form second loop by the drive motor M2 that drives dividing plate 43b, form the 3rd loop by the drive motor M3 that drives backboard 44a, 44b.

Thus, by between dividing plate 43a and the backboard 44a and between dividing plate 43b and backboard 44b, clip columns of items ML respectively and carry, can in conveying mechanism 40, carry with the state that muchs more stable than the past.

At this, the example of enumerating bucket 41 sides specifies by the method for conveying mechanism 40 articles conveyed row ML as follows.Another bucket 42 is also similarly carried with following explanation.

That is to say, the bucket 41 that the assigned position Q that is passed at article M of Figure 21 waits for, when article M when the transfer table 22 of upstream side transports, by dividing plate 43a file leader's article M is accepted to erect posture, and keeps this to erect posture.Then, bucket 41 is with the predetermined distance of the thickness d 1 (Figure 21) of the sack that is equivalent to article M side shifting downstream, thus, and as shown in Figure 25 (a), so that a plurality of article M accepts article M at the state of the rear of the article M that accepts at first queuing.At this moment, backboard 44a waits in the downstream of the assigned position Q (with reference to Figure 26) that accepts article M.With the bucket 42 cooresponding dividing plate 43b in downstream, wait for then in the downstream of backboard 44a.Then as shown in Figure 25 (b), when the columns of items ML that is passed on reaches the regulation number, as shown in Figure 25 (c), between dividing plate 43a and backboard 44a, to clip the state of columns of items ML, as shown in Figure 25 (d), be transported to the position R (with reference to Figure 26) in downstream along second direction Y.At this moment, as shown in Figure 25 (b),, promptly move to the downstream of backboard 44a, accept next group article M from transfer table 22 at the dividing plate 43b that wait in the downstream of the second direction Y that is right after backboard 44a.

[columns of items feedway 2]

Columns of items ML by 40 a/s bags of numbers of line-up device are as shown in Figure 26 lined up is shifted onto on the gig 52 by first push pedal 51.As shown in Figure 16,, released at first direction X by second push pedal 54, and be transported on the conveyor surface 65 of the columns of items feedway 2 shown in Figure 15 after Z1 is lifted above vertical at the columns of items ML on the gig 52.

After this, the lifting push pedal 61 represented of the long and two-short dash line of Figure 16 promotes columns of items ML on first direction X.At this, be provided with directing plate 80 in the both sides of second direction (Width) Y of the conveyor surface 65 of columns of items feedway 2 shown in Figure 15.When lifting push pedal 61 promotes columns of items ML, remain the state of erecting by the pin 91 (Figure 16) that will on second direction Y, be linked to be linearity, the rearward end that is directed the columns of items ML of plate 80 guiding its side Ms is promoted by lifting push pedal 61 and contacts with pin 91 (Figure 16), and each article M is lined up into row.

Then, after above-mentioned queuing, pin 91 (Figure 16) falls down, and columns of items ML is transported on the valve 62.

Then, after above-mentioned conveying, valve 62 is opened, and after columns of items ML was positioned on the bay-lift 63 of the propradation of representing with long and two-short dash line, bay-lift 63 descended to vertical below Z2.On the other hand, setting is in the box B that horizontal mode was fallen and disposed with peristome Bu.Piled up on bay-lift 63 after the columns of items ML, bay-lift 63 drops to the roughly the same position of height of the peristome Bu and the columns of items ML of box B downside.Then, after above-mentioned decline, columns of items ML is shifted onto in the box B case by vanning push pedal 64.

The box B that vanning finishes is rotated and makes peristome Bu up.

The following describes summary as the antidote of the columns of items ML of main portion of the present invention.

[queuing of columns of items ML]

As mentioned above, columns of items ML on the gig shown in Figure 16 52, after vertical top Z1 is lifted, the rear end Md of the columns of items ML that the long and two-short dash line of Figure 27 (a) is represented is promoted at first direction (throughput direction) X by second push pedal 54 (Figure 16), and columns of items ML is transported on the conveyor surface 65 of columns of items feedway 2.

As illustrated below, when pushing columns of items ML with second push pedal 54, the danger that has the front position at the columns of items ML that is pushed by second push pedal 54 to get muddled.

This disorder can be corrected by the pin 91 of the front end Mf that is arranged on columns of items ML, makes the front end of second push pedal 54 neat.

That is to say, when closely on second direction Y, moving and make in the action close to each other to another directing plate 80 as the sack of columns of items ML at the directing plate 80 of Figure 27 (a), columns of items ML becomes arc shape easily, and arc, and dressed the ranks by making columns of items ML and pin 91 butts (contact) can prevent that columns of items ML from becoming.

Make as the sack of columns of items ML close to each other after, when pin 91 begins when the front lower place rotates, the rear end Md of the columns of items ML of Figure 28 (a) is promoted by lifting push pedal 61, as shown in Figure 28 (b),, columns of items ML begins on conveyor surface 65, forwards to carry while being directed plate 80 guiding.So, owing to can when pin 91 begins to keep out of the way action, begin the conveying of columns of items ML, so the high speed that can seek to carry.And, can when columns of items ML passes through on pin 91, pin 91 be returned to original position, so can in the advancing of lifting push pedal 61, enter the action of accepting next columns of items ML.

After this, as shown in Figure 27 (a), 61 couples of next columns of items ML of lifting push pedal prepare and move to than the top of article M more by the holding fix of top.

Shown in the arrow of the long and two-short dash line of Figure 16 (b), lifting push pedal 61 is carried out descending after holding fix upstream direction parallel motion repeatedly, promotes this a series of actions of rear end of columns of items ML at first direction X.

[rectification portion 9]

As shown in Figure 27 (a), be formed with arm 92,92 at the both ends of pin 91. Arm 92,92 is bent into approximate right angle by the both ends with pin 91 and forms.The end of arm 92,92 is fixed on the sidepiece of S. A. 94.S. A. 94 is provided with along the horizontal axis L3 that forms along second direction Y, is provided with first drive division 93 in one end thereof, and S. A. 94 is rotated around horizontal axis L3.

Therefore, by the rotation of S. A. 94, can make arm 92 rotate to various angles.

As shown in Figure 29, Figure 30 (a) and Figure 31 (a), first drive division 93 makes S. A. 94 rotations, makes arm 92 around horizontal axis L3 rotation, just can make pin 91 be positioned at the contact position PT that contacts with the front end Mf of columns of items ML.

Therefore, pin 91, arm 92, first drive division 93 and S. A. 94 have constituted and have suppressed a part of article M from the forwards outstanding rectification portion 9 of columns of items ML.

On the other hand, make S. A. 94 contrarotations, pin 91 is housed in the accepting groove 95 that is arranged on the conveyor surface 65 by first drive division 93, as shown in Figure 30 (b), the retreating position PA that pin 91 is positioned at do not disturb columns of items ML to carry.

The position that is in the pin 91 of retreating position PA is set to the below that is positioned at conveyor surface 65.

[angle initialization of arm 92]

In first drive division 93, stepping motor or pulse motor have for example been used.By motor is controlled, change the angle of the arm 92 that forms by S. A. 94 rotations, the contact position PT of pin 91 can be set in position arbitrarily thus.For example shown in Figure 30 (a), under the smaller situation of article M, make arm 92 in the direction rotation opposite, the feasible distance that reduces lifting push pedal 61 and pin 91 with first direction X.On the other hand, as shown in Figure 31 (a), under the bigger situation of article M, make arm 92 towards first direction X rotation, making increases the distance of lifting push pedal 61 and pin 91.

The angle of arm 92 is provided with by the following method, store each big or small cooresponding stop angle with article M in advance at stop (stopper) the angle storage part as shown in Figure 31 (b), and will comprise that the stop angle of the count number of motor revolution and coder reads from stop angle reservoir accordingly with the size of article M.

[directing plate 80]

As shown in Figure 27 (a)～Figure 28 (b), on two directing plates 80,80,, be formed with circular-arc slit 82 in order to allow pin 91 along the track rotation of pin 91 with arm 92,92 rotations.

As mentioned above, at a directing plate 80A shown in Figure 27, be arranged to go up at second direction Y (Figure 27 (a)) by support 81,81 and move.Connecting second drive division that does not show among the figure on support 81,81, by support 81,81, as shown in Figure 27 (a) and (b), second drive division can make a directing plate 80A go up at second direction Y (Figure 27 (a)) and move.

Therefore, as shown in Figure 27 (b),, directing plate 80 is contacted with the side faces at both ends of the columns of items ML that carries on conveyor surface 65 it is promoted, can shorten the width between centers of the article M among the columns of items ML by making a directing plate 80A near another directing plate 80.

On the other hand, lifting push pedal 61 descends from the top, further, by on first direction X, promoting the rear end Md of columns of items ML, the front end Mf of columns of items ML is contacted with pin 91, and a part that suppresses columns of items ML is forwards outstanding, and columns of items ML can not be transferred dispersedly.

[valve and bay-lift]

Shown in the long and two-short dash line of Figure 30 (b), the upper end that bay-lift 63 drops to columns of items ML is in the position under the valve 62.When carrying next columns of items ML on valve 62, valve 62 is opened, the stacked next columns of items ML that represents with solid line on the columns of items ML that long and two-short dash line is represented.The number of plies that bay-lift 63 is stacked according to columns of items ML, the upper end that drops to columns of items ML successively repeatedly is in the position under the valve 62, columns of items ML superimposed after the regulation number of plies, as mentioned above, drop to the roughly the same position of height of the bottom Mb of the peristome Bu of box B downside and undermost columns of items ML.

When bay-lift 63 descended, valve 62 was closed.After this valve 62 was closed, bay-lift rose a little, between valve 62 and bay-lift 63 columns of items ML was compressed at above-below direction.Even under the situation of size of the columns of items ML that stipulates the number of plies, also can compress the stacked size of single-piece, stacked columns of items ML is pushed in the box B by the action of this compression greater than the size of box B.

[swivel mount 66]

Shown in the long and two-short dash line of Figure 32 (b), the posture that changes columns of items ML sometimes makes the front end Mf of columns of items ML contact with bay-lift 63 and cases.

As shown in Figure 32 (a), on conveyor surface 65, be provided with the swivel mount 66 of a part that constitutes conveyor surface 65.Leading section at swivel mount 66 is provided with S. A. 68, and making swivel mount 66 is the center rotation with horizontal axis L4.S. A. 68 is connected with the 3rd drive division 69 (Figure 27 (a)).

When the rear end of columns of items ML Md is promoted by lifting push pedal 61 and when being transported on the swivel mount 66, making swivel mount 66 by the 3rd drive division 69 of Figure 32 (b) is that the center rotates about 90 ° with S. A. 68, and the front end Mf that changes into article M becomes the posture of lower end.

Under the situation of illustrative example, in the other end of swivel mount 66, end 67 is by inwardly bending, so that the unlikely centnifugal force owing to swivel mount 66 of article M flies out thereafter.

For the angle initialization of arm 92, also can use drg that arm 92 is stopped with the angle of regulation, replace control with this as the motor of first drive division 93.

Rectification portion 9 also can be arranged on except that conveyor surface 65 on the gig 52, earlier the queueing condition of columns of items ML is corrected by second pin that is provided with on gig 52.

Above with reference to description of drawings preferred embodiment, it is contemplated that those skilled in the art after having seen this specification sheets, obviously be easy to expect various changes and correction in scope.

For example, according to the information of the size of article M that is arranged on upstream side or sack, can when the kind (changing layer) of change article, whether judge to the control of arm angle or the rotation of swivel mount automatically.

Therefore, so change and revise and may be interpreted as in the scope of the present invention of claim defined.
