Abstract

PURPOSE:To achieve automatic discharge of preceding group by predetermined amount by driving a partition into material stacked continuously in zigzag on an elevator finger with timing thereby separating perfect into preceding group and following group. CONSTITUTION:Upon reaching of material stacked in zigzag on an elevator finger 4 to predetermined amount, a partition 30 is driven between the upper face of the stacked material and the following paper chip T'. Consequently, direct stacking of following paper chip T' onto said material T is prevented. Then the stacked material T lower than said partition 30 is lowered without disturbing the zigzag condition, thus to form a gap between the stacked material and the following paper chip T' supported on said partition 30 in zigzag. Then the uppermost paper chip R1' of said stacked material T and the lowermost paper chip P2' of the following paper chip group T' are separated. The rised uppermost paper chip P1' is sunk into the upper face of said stacked material T while the falling lowermost paper chip P2' is applied with horizontal force from the rear to be converged to the bottom face of the following paper chip group T'.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for automatically taking out a zigzag-folded stack of towel paper or similar paper, which is stacked by continuously folding two sheets together in a zigzag manner.

[Prior art and its problems]

Towel paper is a relatively thick paper unlike tissue paper, but like tissue paper towels, it is widely used because it is convenient and can be quickly taken out and thrown away after wiping hands and face.

In order to make this towel paper the most convenient to use,
Continuation - (Two systems) of towel paper are alternately shifted and folded in a zigzag pattern. For this reason, conventionally, rotary folding devices consisting of a pair of rotating rolls have been mainly used.

This (dl) Two sheets of paper are cut separately from the web fed by two systems, and the cut edges are shifted from each other, and the two sheets are combined between a pair of rolls to produce a continuous zigzag-shaped folded product. Such automatic folding equipment is operated at a high speed due to the requirements of mass production, and therefore the towel paper produced is folded in a zigzag manner at a high speed. In order to make a product, a certain amount of the knob-zab-folded material must be separated into boxes, packaged, and disposed of in the next process, but the zigzag-folded material is produced one after another at high speed. In any part of the paper, two types of paper strips are folded over each other to form a continuous shape, so it is difficult to separate the quantitative amounts in an orderly manner without disturbing the zigzag folding state, making it difficult to mechanize. In reality, marks were placed every few stitches on the stack that was folded in a continuous zigzag pattern by an automatic folding machine, and the items were separated manually using these marks as guides.

(7) However, there are various points of separation in such conventional methods.

First, while there is a need to make automatic folding machines larger and faster in order to increase production efficiency, it is not possible to automate the processing (quantitative extraction) of the output, so it is necessary to rely on human labor. Although this is a good thing, human abilities are naturally limited, which poses obstacles to increasing the size and speed of folding machines themselves.

Secondly, the work environment where automatic folding machines are installed is full of machine noise and paper dust, so it is not healthy for people to work non-stop while the machines are running. There are many problems, and there is a strong demand to reduce the human labor involved in the extraction work.

Thirdly, not only are the feeding, cutting, and folding of base paper automated, but also the output (towel R1, etc.)
) boxing and packaging work has also been automated, and only the quantitative extraction work that connects these two automated parts is not automated and is largely manual work, so there is a request to completely automate this manual work part. There is a strong 1.

[Purpose of the invention]

The present invention has been made to solve these problems, and its purpose is to continuously form towel paper or similar relatively thick paper into zigzag folds without hindering the process. Another object of the present invention is to provide an automatic taking-out method that can orderly take out a certain amount without disturbing the zigzag folds that have been formed, and an apparatus for carrying out the method.

[Summary of the invention]

Method of the present invention ← 1. A method in which two sheets of relatively thick and stiff paper, such as paper towels, are folded together in a continuous zigzag pattern, and a predetermined amount of the accumulated material is taken out. , the number of folded items to be accumulated is counted, and when it reaches a predetermined amount, a partition is inserted between the zigzag folds that are about to be formed, and the zigzag folds above it are Prevent the subsequent part that is about to be folded from directly folding over the part +- that has already been zigzag folded and accumulated, and then separate the accumulated part below the partition from the subsequent part above the partition and fold it between them. By creating a gap between the uppermost piece of paper in the stacked part and the lowermost piece of paper in the succeeding part, the uppermost piece of paper in the stacked part settles on top of the stacked part by its own weight, and the lowest piece of paper in the subsequent part A mechanical or pneumatic force is applied to the paper pieces in a substantially horizontal direction from the back side to the front side to cause the paper pieces to converge on the bottom surface of the succeeding part, and then the accumulated part is further lowered and discharged to the next process, and the above-mentioned upper part The subsequent part consists of waiting for a predetermined amount of new accumulation and repeating each of the above steps.

The device of the present invention for carrying out such a method has a pair of slide posts erected under the automatic folding machine, and a horizontally installed slider that can move up and down along the child ride posts. A large number of elevator fingers are erected at predetermined intervals to receive the continuous zigzag folded material from the folding machine, and a swinging arm is installed in front of the elevator fins so that the elevator fins are intermittently driven into the upper surface of the predetermined amount of folded material. A count finger is provided which also serves as a temporary support for the accumulated material, and behind the elevator finger, the elevator finger and count finger are attached to a support par installed horizontally on the slide post line [block so as to move back and forth. A large number of support fingers are erected at intervals that do not interfere with the elevator finger, and a clamp/f finger that temporarily presses the rear edge of the elevator finger during the descent of the elevator finger carrying a certain amount of folded items is placed in conjunction with the elevator finger. A discharge conveyor is provided in combination to discharge the folded material at approximately the same height as the lowered elevator finger.

[Embodiments of the invention]

A preferred embodiment of the present invention will now be described with reference to the drawings. Fig. 1 shows the present invention implemented as an automatic metering device for taking out continuous zigzag folds from a rotary towel folding machine. A conceptual diagram of the example as seen from the front is shown, and FIG. 2 is a cross-sectional side view of the main part of the apparatus shown in FIG. 1.

In Fig. 1, one folding roll R is shown by a button line, but in reality, as shown in Fig. 2, it is configured as a pair of folding rolls R, , R2, each roll R, , R2. As shown in Fig. 2, a continuous web-like material (towel-like paper) P+, F2 is fed from the left and right as shown in Fig. 2, and is held on the roll surface by suction or other means until it reaches the cutting section C. , , and C2, respectively. However, the cut pieces of paper are still held on the circumferential surfaces of the rolls R, , R, and are sent to the contact area between the two rolls without separating from the web-like base paper that follows in the running direction. Cutting is performed when the cutting edge Cu protruding from the roll circumferential surface comes into contact with each of the cutting parts C, C2, but as can be seen from FIG. For example, R2
Since one cutting blade of R is placed between the two cutting blades of The cut edge of the other piece of paper is placed on the edge of the other piece of paper. The two cut paper pieces thus combined are alternately held mechanically or by suction on the surface of either roll R1 or R2, and are allowed to alternately swing under each roll as they are carried downward from the contact area. When it is peeled off from the roll surface by the provided folding par F or F2, it is pressed from above by the folding par and folded to become a zigzag folded material T. In Figure 2, S is the swing shaft of the folding par. The groove in which this folding par enters the roll surface for stripping is indicated by G in FIG.

In Fig. 2, the already folded and twisted cut paper piece P,
' (ordinary towel wave - length of eJ sheets) is folded over half of another cut paper piece P2', and the remaining half of P2' overlaps and is continuous with the first half of P1' that follows P1'. It forms a zigzag shape and is about to fold onto the accumulation T by the folding par F2. The present invention provides a device for automatically and orderly taking out a zigzag-folded product from such an automatic folding machine in fixed amounts without disturbing its folded state or interfering with the folding operation. Since the automatic folding machine itself is just one example, it is not limited to the one shown in the figure, and other forms may be used.

Returning to FIG. 1 and explaining the automatic take-out device of the present invention,
A pair of slide posts 2.2' are erected inside the pair of frames 1 and 1'.

A sea urchin elevator Par 3 is installed horizontally so that it can slide up and down along the slide post J2.2'. A large number of elevator fingers 4 on which zigzag folded products T (see FIG. 2) are placed are attached to the elevator par 3 at intervals.

Although the zigzag folding material T is not shown in FIG. 1, the material T is formed under the folding roll R over a length approximately equal to the length of the roll surface (length in the axial direction), and is formed in large numbers. It is laid across the elevator finger 4. As will be described later, this aggregate T is longitudinally cut into a width of about 20 crn (the width of one ordinary towel towel) in the next step.

Referring to FIGS. 2 and 3, the elevator finger 4
A rack 5 is installed between the elevator par 3 to which the elevator par 3 is attached and a slide block 3' provided below it so as to be able to slide up and down along the same slide block 2.2'. is fixed to the transverse shaft 7. As shown in FIG. 3, the drive mechanism for the shaft 7 is such that an input gear 8 is fixed to the center of the shaft 7, and a gear 9 that meshes with the input gear 8 is connected to one end of a powder clutch 10. The other end is connected to a gear 12 via a gear 11, an arm 15 is attached to a gear 14 that meshes with a gear 13 integrated with the gear 12, and a cam follower 16 supported by the arm 15 is engaged with a cam 17a. With this mechanism, the shaft 7 is rotated in both directions as shown by the arrows in FIG.
is moved up and down along the slide post 2.2'.

The elevator finger 4 is associated with a clamp finger 20, as shown in FIGS. 2 and 4. The clamp finger 20 temporarily holds (clamps) the upper edge of the zigzag folded material T on which the elevator finger 4 is descending (the upper left edge in FIGS. 2 and 4).
It's no good. Specifically, as shown in FIG. 4, the upper end of the Franz 0 fin 20 is formed as a bent end 20a, the lower part of the clamp finger 20 has a clamp inserted through the id 21, and a projecting pin 20b provided in the middle. protrudes from a curved slot 22 formed in the tube wall of the clamp guide 21. The crank 0 finger 20 is raised when the elevator fin moves up and down with 4, and the clamp is moved up and down at idle 2.
1 is fixed, when the elevator finger 4 starts to descend, the clamp finger 20 also descends, and its projecting pin 20b moves along the curved slot 22, causing the clamp finger 20 to move as shown by the circular arrow in FIG. The folded end 20a advances to the position shown by the chain line and presses the trailing edge of the zigzag folded material T.

The bent end 20a of the curved slot 22 is in the retracted position when the elevator finger 4 is at the lowest and lowest position, and the curved slot 22 is pivoted so as to overlap the trailing edge of the stack T in the middle. It can be formed into a shape that looks like this.

Solenoid 2 placed near the lower end of clamp guide 21
3 (FIG. 4), the protruding pin 23a is engaged with the notch 20c of the clamp finger. When it is detected that a predetermined amount of the zigzag folded material T, in which the elevator fins 4 are collected, has reached a predetermined amount, the protruding pin 23a is retracted, and the crank fin 20 can be lowered. 24
, 25°26 are compression springs.

Referring to FIGS. 2 and 5, the elevator finger 4
A count finger 30 is provided on the front side facing the counter. When a predetermined amount of the zigzag-folded material T is detected, the counting finger 3° is inserted as a partition between the upper surface of the predetermined amount of the material and the subsequent paper strips, and the subsequent paper strips that are subsequently folded in a zigzag manner are This is to prevent the predetermined amount from being directly folded onto the accumulated material T. The position where the count finger 30 is driven is between P÷ and Pl in FIG. 2, and the count finger 3o driven into this position is in the state shown by the chain line in FIG. 5.

A large number of counting fingers 30 are provided at intervals in a horizontal line, as shown in FIG.

The multiple count fingers 30i are attached at predetermined intervals to a support par 31 that is horizontally suspended in front of the elevator fingers 4. Both ends of the support par 31 are connected to the swing arm 32 (fifth
(details shown in the figure), and the swinging arm 32 is connected to another swinging arm 34 via a fulcrum shaft 33. Swinging arm 34
17) The lower end is tensioned by a tension coil spring 35. Return is performed by cylinder 35'.

A hook 36 (FIGS. 2 and 5) is constantly engaged with the count finger 30 to hold it in the inoperative position (the position shown by the solid line in FIG. 5). A sector 38 is pivotally attached to the hook 36 via a fulcrum pin 37, one end of the sector 38 is connected to a protrusion of a solenoid 39, and a ratchet pawl 43 is pivotally attached to the other end of the sector 38. ratchet boil 42
A cam 41 is fixed coaxially with this, and a follower 40 supported at the lower end of the hook 36 engages with the cam 41. When a predetermined amount of zigzag folded material T is detected on the elevator finger 4, the solenoid 39 is energized and the protrusion is retracted, so the ratchet boil 42° cam 41 is rotated and the follower 4o is pushed up and counted. The finger 3o can now be driven from the position shown by the solid line in FIG. 8 to the position shown by the chain line. Note that 45 is a ratchet wheel par, and its rear end is connected to a cam ring 46.

Returning to Figure 2 again, the back side of the elevator finger 4 (
A support finger 50 is arranged on the left side in FIG. While the elevator finger 4 descends with a predetermined amount of zigzag folded material on it, discharges the collected material to the carry-out conveyor 70, and then ascends again, the Zaport finger 50 continues to fold the subsequent zigzags that are formed one after another. The function of receiving origami pieces on behalf of the elevator finger 4, and the function of receiving the paper pieces hanging at the bottom of the following paper pieces group when a predetermined amount of preceding zigzag folded material is separated from the following paper pieces group as described later. It functions to apply a mechanical horizontal force to the group of paper strips to converge them to the bottom surface (downward correction).

The support I finger 50 is a slide block 5 provided so as to be able to slide up and down along the slide post 2゜2'.
] (Fig. 2) A slide/gift 52 is extended and fixed almost horizontally to the rear of the slide/gift 52, and a support par 5; A large number of them will be erected. As shown in FIG. 1, the support finger 50 is also the elevator finger 4.
The count fingers 30 are arranged at intervals that do not interfere with each other.

Referring to FIG. 6 regarding the drive mechanism of the support finger 50, the vertical movement of the support finger 50 is controlled by an air cylinder or hydraulic cylinder 54 connected to a slide block 51.
The back and forth movement is achieved by a rod 55 and a lever 56 (also visible in FIG. 1) connected to both ends of the support par 53. The lever 56 has a short arm 58 via a pivot shaft 57, and when the follower (dotted line) supported by the lever 56 is moved by a force l·60, it swings between the solid line position and the chain line position to move the support par 53, support finger 50
move back and forth.

The method of the present invention will now be described in conjunction with the apparatus described above with reference to FIGS. 7 et seq.

First, in FIG. 7, when the zigzag folded material T reaches a predetermined amount on the elevator fin 4, the elevator finger 4 is lowered slightly at the same time (
At the same time as arrow a), a counting finger 30 is placed between the top surface of the predetermined amount of accumulated material T and the succeeding piece of paper as shown in FIG.
Insert it as a partition (arrow b). At this time, the piece of paper closest to T of the counting finger 30 is cut from the right web p, (see Fig. 2) and is already completely =
It is the upper half P1' of the folded paper strip, and the one closest to the upper surface of the counting finger 30 is the lower half P1u of the paper strip held on the circumferential surface of the roll R1 whose upper half is half-length. P,' and P,'' are the continuous web P1 before passing through the cutting part C1 (Fig. 2).The web P1 that is on top of Pl' is a web cut from the web P2 coming from the left. This is the upper half of the folded one, and its lower half P2' has entered under P1' under the counting finger; ′ must be carefully removed, the predetermined amount of accumulated material T cannot be separated in an orderly manner from the succeeding group of paper pieces.

As shown in FIG. 9, the counting finger 30, which is driven as a partition at the position where a predetermined amount of accumulated material T is separated, is placed on top of the counting finger 30, as shown in FIG.
Subsequent paper strip groups T' are accumulated one after another (note that the folding bars F, , F2 are vertically oscillated by the number of folds formed under each from FIG. 8 to FIG. 9). ).

The counting finger 30 temporarily receives the succeeding sheet group T' in this way, and when the later-described Zahot finger 50 appears (Fl
Wait for Figure 1). In the meantime, the elevator finger 4 is further lowered (arrow C in FIG. 9) to create a gap between the predetermined amount of accumulated material T and the succeeding paper strip group T'.

Along with this lowering, the crannofin 20 is turned as shown by the circular arrow in FIG. 9, and its bent end 20a presses the rear upper edge of a predetermined amount of the accumulated material T.

In this way, the fold line on the rear side of the predetermined amount of accumulated material T is held down so that it does not collapse, and the uppermost piece of paper P1' is clamped at its lower half edge, so that it cannot be pulled out to one side. On the other hand, F2 hanging down from the succeeding paper strip group T'
The upper half is above the count finger 30, and subsequent knob-zab folds are formed one after another on top of it, so it is effectively held down by either the folding par F or F2 on the seat and is pulled out downwards. I never release it. When the elevator fin lowers 4 and the predetermined amount of accumulated material T above it, as shown in FIG. The lowest piece of paper P2' of the succeeding paper piece group T' is P,' stands up, and P2' is released from overlapping with each other in a vertical position, disturbing the folded state of each other's 11 sheets. 3. The towel cover and other materials are relatively thick paper and stiff, so the top layer of paper separated as shown in Figure 10)"l III'N1, Flutters in the wind. It is stored in such a way that it sinks a predetermined amount into the upper surface of the stack T due to its own weight (see P1' in FIG. 11).3 This is referred to as "upward adjustment" in the present invention.

The pieces of paper P21 hanging down from the following group of paper pieces T' must be converged to the bottom of the following group of paper pieces T' (this operation is referred to as "downward correction" in the present invention)4. The downward revision is
After the predetermined amount of the accumulated material T has descended sufficiently, this can be done by applying a mechanical force or, if necessary, an aerodynamic force from the back to the front of the hanging piece of paper P2' in the direction of the water. The figure shows an example of using mechanical force. That is,
71 will wait at the rear at that moment? -＋・play)
50 in the direction of arrow d and raised in the direction of arrow e, the hanging paper piece P2' is scooped up and approached to the bottom of the succeeding paper piece group T', and at the same time,
The subsequent sheet group T' itself is counted from the counting finger 30 to the s5 1. Hand it over to finger 50. The count finger 30 is immediately pulled out in the direction of arrow f and returns to its original position.

In this way, the upper surface of the descending predetermined amount of accumulated material T is paper j-1"
On the other hand, due to the self-weight of l', a downward correction of the group T' which is forming a subsequent nog fold is caused by the 71
made by e-toff rate 50 and two groups T and T
' are separated cleanly, then the elevator finger 4 is further lowered and its mounting surface 4. a (FIG. 12), when it reaches almost the same height as the carry-out conveyor 70, the clamp blade 20 rotates again as described above and removes the bent end 20a from the trailing edge of the stack T3. The predetermined amount of accumulated material T is transferred to the carry-out conveyor 70 with the paper pieces P,' completely submerged and discharged to the next process (in the direction of arrow g). In addition, as mentioned above, since the above-mentioned /ζζ aggregate has a long surface length that is almost the same as the surface length of the folding roll R (see Fig. 1), the next step is to remove it from an ordinary towel -ε −・
This is the process of longitudinally cutting the web Pl to the width of one sheet of web Pl before it enters the folding roll R or from being passed through the folding roll R.

If P2 is cut vertically (slit) to the width of one sheet, the next step is a boxing and packaging step.

Immediately after the elevator finger 4 has finished discharging the accumulated material T, it ascends again (as indicated by the 1.31\1 arrow h) and approaches the Zaport finger 50. When the elevator finger 4 comes into contact with the bottom of the trailing group T' on which the support I fins 50 are steadily folded, the support finger 50 slightly descends (arrow i) as shown in Fig. 1/1. It is pulled out backwards (arrow J), then rises and returns to its original state (Fig. 7). When it is detected that the subsequent group T', in which the elevator fins have been taken over on 4, reaches the predetermined amount again.
- is repeated. The present invention is not limited to the embodiments described above. For example, if the count finger 30 is configured to increase the amount of the succeeding sheet group T' temporarily received by the count finger 30, the second fin 50 can be omitted.
I can do it. This counter finger functions both as a partition and as a temporary support until the elevator fins rise, but when the support fins are
It does not have the function of downwardly correcting the succeeding paper strip group T' as shown in FIG.

Therefore, in this case, as shown in FIG. 15, the succeeding group T' on the count finger 30' is
′ hanging down until elevator finger 4 or 1 rises.
If the elevator finger 4 is left as an ox, the following rock τT'
When approaching the bottom surface of P2', the horizontal cuff 6 is applied from the rear to the front of P2', and the elevator finger 4 is brought into close contact with the bottom surface of the succeeding group T' to perform a downward adjustment. As the horizontal cuff 6, mechanical force such as (I'j:, 70)/yufinger may be used, but air blowing is preferable.

The present invention is applicable not only to the above-mentioned towel waver, but also to automatic quantitative removal of zigzag folds of relatively thick and stiff paper or other materials. But it's hard.

〔Effect of the invention〕

As explained above, according to the present invention, the elevator fins are driven into the pile by coordinating the quimming to the stack of elevator fins that are continuously folded in a zigzag manner, and the trailing group above the partition and the leading group below the partition are separated. , it is possible to separate the groups in an orderly manner without disturbing the folded state of any group, and discharge the preceding group in fixed quantities without having to do it manually, making it possible to fully automate the manufacturing process of zigzag folded products, eliminating the traditional bottlenecks. It is possible to solve this problem in a brotherly manner.

Unfortunately, in the device of the present invention, by inserting a clutch into the drive system of the elevator finger, even if the folding height changes due to changes in the number of products or the paper thickness, it can be skillfully handled and automatic removal can be performed smoothly. You can do something like that. Furthermore, by inserting a clutch between the folding device and the folded article take-out device, there is an advantage that the number of sheets to be taken out can be easily changed.
