Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the supply and transportation of paper products, and more particularly to the separation of individual paper products from a pile at extremely high processing speeds.

Generally, prior art feeding and transporting devices for separating and feeding individual paper products from a pile are of the bottom, side or top feeding type. The present invention is limited to archived documents because there is generally a significant variation in the frictional forces induced by pulling a single product against the weight of the pile.

This rod feeding technique often has the drawback of requiring complete withdrawal of one product from the stack before subsequent documents can be processed, thus limiting the flexibility and speed of the device.

In other devices, the timing of the product withdrawn from the pile;
Or there is a defect that does not control the positioning and therefore requires subsequent retiming using synchronized or precisely timed processing equipment with drawn products.

The typical maximum processing speed of a prior art Sakaki processing device that processes one product at a time is approximately 12.0 per hour (divided by 10 units).However, all of these types of devices, unless parallelized, It cannot be directly connected to a high-speed device that can process 40,000 to fio, 000 pieces.

Other deficiencies of prior art devices include ■ complex equipment that is expensive to purchase and maintain, ■ lack of precision in document timing due to synchronous operation of direct-coupled operation, and ■ considerable Consists of the use of space.

It is therefore an object of the invention to improve the state of the art and to
It is an object of the present invention to provide a high-speed feeding device which eliminates the above-mentioned deficiencies and can therefore be used in direct or non-coupled connection with high-speed rotary presses or other high-speed equipment.

Therefore, according to the invention, between 40,000 and 60
A high speed feeding and transport method and apparatus is provided that is capable of separating individual paper products from a pile at a rate of . This device can be used, for example, to separately button feed preprinted folds to a direct-coupled device operating at printing speeds with precise spacing, speed and orientation such that a plurality of signatures can be fed directly to the direct-coupled processing device. You can.

One or more sheets of paper products are stacked edge-to-edge in a substantially vertical position towards the roller stozzo in any quantity. The sheets are bent away from the pile at the bottom of the pile and gripped in the pile by seating them against the recesses of a corrugated rotating member such as a disk or drum for precise spacing and pulling them out of the pile. .

Subsequent paper products are placed and withdrawn from the stack in a generally horizontal direction, thus arranging the products in a chess-to-chest configuration, thus further increasing speed and reducing friction.

The separated product is conveyed in an arc of approximately 180' on the rotating member, so that it is in a substantially horizontal position i at the bottom of the rotating member.
It is released as t is reached. During this arc-travel distance, the shogi-toppling document is held against the circumference of the rotating member by a flexible belt moving at the same speed 11 as the circumference of the path adjacent to the transport arc. The products are then discharged onto a conveyor in a timed sequence for further transportation and some other uses.

Other features, objects, and advantages of the invention will be understood from the detailed description, accompanying drawings, and claims that follow.

60 per hour by feeding a single sheet product from a pile,
There are a number of factors that have prevented the prior art from achieving accurate speeds and spacing at very high speeds such as 1,000,000.

When moving products such as the signatures on page 48, it is customary to use extremely heavy and cumbersome equipment due to the initial inertia and frictional traction forces against the pile. be. However, as can be seen in FIG. 1, the present invention, which operates on a different principle, provides a simple, reliable and inexpensive device.

Therefore, the paper products 15 are placed on the tray 16 which is slightly inclined from the horizontal to hold the products almost vertically.
is deposited on top of the rim. For multi-sheet products, the fold is the bottom. Product stop is a set of rollers 17
The rollers reduce the tensile frictional forces when the product is pulled out of the pile. The stack of products may be such that the number of documents cannot be limited and may be received from the supply mechanism by placing them in bundles or by manual loading. Preferably, a constant feed is applied at the rear of the stack by suitable means (not shown), so as to fix the paper product against the stop roller 17 with a predetermined force. The downward feed slope of the ramp or tray 16 assists in feeding the document towards the stop roller 17.

The rotating member 1B has a corrugated circumferential portion 19 with a plurality of accurately spaced recesses so that the continuous sheets n fed from the bottom of the stack 15 are aligned and fixed in the recesses. The initial separation inertia will therefore be very low since only the lower edge of the product needs to be moved with negligible frictional forces and much less weight than the entire product. .Also, the distance over which those products are moved is smaller, and those products can be moved without interfering with moving vacuum grippers, etc., and those product roots that grip the products after separation have a lower acceleration instead of an instantaneous one. The reciprocating arms are able to work gradually at speeds, so that a reliable high-speed separation of the individual products is facilitated by the suction device located in the reciprocating arms, which move the products into the recesses of the corrugated circumferential part. The rotation of the rotating member 18 is synchronized with the rotation of the rotating member 18 so as to bring about, in this case, exactly the rotation of the rotating member 18.The rotating camshaft 5 therefore reciprocates the bending member accordingly, which bends as the suction member reciprocates. Preferably, the suction material is dispensed synchronously with the suction action to grasp and release each document.

In order to further increase the separation and processing speed for handling paper products n from the stack 15, two bending members are connected to the cam wheel 4.
5, the suction member 2 is reciprocated in an appropriate phase.
3A, the second bending suction member n becomes engaged and activated before the first suction member releases the first product and returns. It is clear that the bending means 23-25 are low inertia mechanisms that do not need to operate at very high speeds. As best seen from FIG. 5, rotating member 1
Advantageously, 8 consists of a set of discs, in which cams 5, suction arms U and similar control mechanisms are suitably mounted between the discs and along and around the axis of rotation of the discs. Can be done. It is important that the mode of movement of the paper product and the short distance between the folded products prevents interference of the separating members and that the short path of travel simplifies operation and thus improves reliability.

Further, as can be fully understood by looking at FIG. 2, the rotating member 18 simultaneously processes a number of single sheet products 22, 22A, etc. The rotating member 18 with the corrugated edging (9) and the four-part side rotates counterclockwise as shown.
The individual products are fixed securely and precisely in known positions, ie at the bottoms of successive recesses. For this purpose, the intervals and timing frequency are precisely controlled to eject individual paper products. The rotating members 18 can rotate at any suitable speed in synchronization with a direct coupling device (not shown) for dispensing their products.

The present invention has the advantage of allowing a low speed rotating wheel assembly,
The clamping therefore ensures that each successive paper product is gripped by the mechanism 31 and thus pulled out of the stack 15 against the rollers and adjacent products. In this way, about 38. A corrugated wheel with corrugations spaced 15 inches apart only needs to rotate at 2,500 revolutions per hour to process 60,000 products per hour. In other cases it is necessary to enable this processing speed of 60
, 000 revolutions per minute, it goes without saying that much more reliable and accurate operation of the device is required. Another advantage consists of low energy, etc. Thus, instead of instantaneously grasping and releasing the entire product at high rotational and surface speeds, the cam 31 is moved gradually and relatively slowly to the appropriate location. Moreover, once the product is received and gripped on the four sides, the clamping does not even have to be moved by the mechanism 31, and when it is moved, if necessary, it is moved with a very low relative acceleration and with a low corrugation wheel speed.

The present invention thus provides a grasping operation with extremely high efficiency and individual throughput, the time during which the grasper must be activated is extended and the product is kneaded over the entire length of the document.
It is gradually accelerated over a stroke of cm (2 inches).

Several products are processed side-by-side at the same time, thus reducing relative travel intervals and increasing single product speeds. It is clear from the mode of product separation that the plurality of products have different directions! From the vertical storage position to the almost horizontal drawer I, which is tangential to the rotary member]8, it has a very short friction path adjacent to the product on either side, and the weight of the compost Travel distance is reduced when compressing a document. In this way, frictional forces are minimized. Moreover, since each family of continuous products is moving, only the total distance between the four adjacent parts becomes the net total frictional polymerization distance when the products are discharged in a chess-to-chest arrangement as shown in the figure.

As can be seen in FIG. 3, the simple mechanism for operating the tightening mechanism 31 consists of a fixed cam wheel 32 about which the rotating member 18 rotates. The mechanism 31 is tightened by the shaft 3.
It is held against the cam wheel by a spring so as to be pivoted around the stop 31B to clamp the product against the stop 31B. Therefore, over the entire outer radius circumference of the cam 32 over the arc 37, the clamping mechanism is activated when receiving a paper sheet into the recess distribution, as shown by paper sheet B in FIG. It is understood that it will be open to the public.

However, the remainder of the rotational arc of the rotating member 18 (the
80°), this clamping means that the clamping device is moved into position and thus holds the paper product in place for transport around the periphery of the rotating member and
As the paper product approaches the position to be released for horizontal transport adjacent to the peripheral seat of 8, it is moved to the release position. Some continued representative tightening conditions are shown corresponding to the grasping features of FIG. It is clear that the shoulder ring 31 on the cam surface (thus releasing the grip of the paper product takes place).

As is clear from the apparatus diagram in FIG. 4, a conveyor belt 4 that is conveyed in a manner similar to the circumference of the shogi-shaped paper-JJ type product rotating member 18 and is typically installed in a horizontal direction.
The shogi pieces are arranged in exactly the same way as the shogi pieces placed on top of zero. However, its direction can be changed.

As the plurality of products rotate around the arc of rotation member 18, the products are, of course, spaced about 3.7 meters (1% inch) apart and have a product surface rate of about 228 cm (90 inches) per minute. The rotational member 18 is restrained by a flexible belt 42 which is carefully and precisely controlled at such a speed that it moves at the same speed as the circumference of the rotating member 18. The accelerator roller 39 then accelerates the movement on the conveyor belt and can perform increasingly gradual four-degree changes in order to avoid shuffling the products, i.e. to separate them, thus allowing the use of separate single products. In this way, a surface speed of 15 m (55 inches) / 60,000 products per hour or 1,000 products per minute
By starting at a speed per minute and continuing to increase speed, the product (30, (12 inches) long) moves separately at 30 m/min.

It therefore turns out that the feed transport mechanism is the simplest and requires only a small amount of floor space. This device is inexpensive and easily maintained, yet is reliable and accurate and operates with improved precision control of document spacing and speed over a greater speed range than has been successfully achieved in the trenches.

Furthermore, it can be seen that the perspective view of FIG. 5 illustrates the simplicity of the multi-disk rotating member 18 and belt arrangement 42. In this arrangement, the tightening mechanism is only provided by two intermediate partial disks.

It should therefore be appreciated that this advance in the art constitutes a patentable improvement and that features which define the spirit and essence of the invention are set forth in the appended claims.

A high-speed separating and feeding conveyor system for paper products is a direct variable speed separating and feeding conveyor system that accurately converts signatures of one page or more from piles of unlimited thickness to printed newsprint at direct variable speed rotary press speeds. The actuator is actuated to provide a oriented, timed and spaced array for further insertion or direct feeding to a processing device. This device can be used advantageously for other paper products fed from stacks for synchronous direct use of other devices requiring precise product speed and separation.
