APPARATUS FOR STACKING AND TRANSFERRING BUNDLES OF PRINTED SHEETS IN SUPER-IIIGII-SPEED ROLLING PRESS BACKGROUND OF THE INVENTION When the running speed of a rolling press increases from ordinary 100,000 sheets per hour up to 160,000 sheets per hour SUMMARY OF THE INVENTION This invention relates to an apparatus to accumulate a predetermined number of bundles of printed sheets into a stack and then to transfer said stack automatically and continuously harmonizing with the.running speed of a super high speed rolling press.

The object of this invention is to construct an apparatus where the mass of moving parts is extremely cut off at the same time the range of motion of the moving parts is shortened beyond the ordinary steps of consideration.

A further object of this invention is to create a new type of turntable which usually occupies most part of moving mass and improve the mechanism cooperating with the same. That is, the ordinary circular form of the turntable is cut away by a straight line in the front and rear sides to take off the superfluous mass and to let the front and rear guide partition plates provided adjacent to the front and rear straight edges participate in the necessary functions.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan of the invention.

FIG. 2 is a front view in section along the line 2-2 of FIG. 1.

FIG. 3 is a side view in section along the line 3-3 of FIG. 1.

FIG. 4 is a front view illustrating one of the essential parts of the invention.

FIG. 5 is a further plan of the invention.

FIG. 6 to FIG. 8 illustrate the essential parts of the invention in operation.

In the drawing, reference numeral 9 is the bed; 10 is the frame; 1] is a turntable of partly circular form in which the superfluous parts have been cut off in straight lines at the front and rear side of the turntable. Part 12 is a pivot of said turntable. Part 13 is a vertical bearing. Part 14 is a rotary torque actuator of known construction which acts to rotate said tumtable as far as 180 with every drop of bundles l5, 15', 15'', arranges them in opposite direction to each other, stops the rotation of the same when a predetermined number of bundles have accumulated forms a stack and transfers the finished stack. Parts l6, 16' are guide plates fixed on the turntable for arranging the side edges of the printed sheets of the bundle. Parts l7, 17 are brackets to support said guide plates finnly. Parts l8, 18' are free rotatable rolls arranged on the turntable for transferring the stack. Parts l9, 19' are bearing frames supporting said rolls. Parts 20, 20', 20", 20" are transferring rolls. Part 21 is a relay roll provided adjacent said transfer roll 18 which can swing up and down. Part 22 is a transferring roll situated adjacent to the turntable, the spindle thereof being the fulcrum of said swinging relay roll 2]. Parts 23, 23 are rocker arms which are supported by spindle of transferring roll 22 at one end supports the relay roll 21 at the other end. Part 24 is an oil cylinder and part 25 is the piston of the same.

According to the invention, by the downward motion of piston 25, the relay roll is made to swing down so as to prevent blocking of the passage of the protruded portion of the turntable lll during rotation. The roll 21 is raised to the level of the transferring rolls when the predetermined number of bundles are accumulated to make a stack, except that time it is lowered under the level of the turntable 11. I

Part 26 is a chain for driving the transferring rolls. Parts 27, 27' are wire belts by which the stack is transferred off. Guide plates 28, 28 are provided adjacent to the front straight edge of the turntable for arranging the front edges of the accumulating bundles. Said guide plates 28, 28 can swing forward and rearward around their axles 29, 29'. The guide plates 28, 28' are made so as to swing rearward to push the finished stack when it is to be transferred, while being able to swing forward for making the turntable rotation without hindrance. (See FIG. 8 and 7).

Rear guide plates 30, 30' are provided adjacent to the straight edge of the turntable to arrange the rear edges of the bundles. Plates 30, 30" are able to swing rearward around the axles 31, 31 to pass the protruded part of the turntable when it turns. The plates 30, 30' are made so as to be displaced up or down. This is done by bellcrank levers 32, 32' pivoted at 36, 36' respectively and connected together by a link 40. One of said bellcrank levers has a projection 33 worked by a roller 35 which is worked up and down by an oil cylinder 34. When the stack is to be transferred, the rear guide plates 30, 30 are raised to the upper position, as shown with the chain lines in FIG. 4. The mechanism to swing the rear guide plates rearward to pass the protruded edge of the turntable 11 is shown in details in FIG. 5, where electric magnet 37 and spring 38 pull back the arm 39 by the attraction of the magnet 37 when it is released. Said arm 39 pivoted at a vertical axle 31 carries said bellcrank levers 32 and 32' which also carry one of the rear guide plates. Therefore, when the magnet 37 is excited, the rear guide plates swing rearward to open the passage of the turntable.

The apparatus of this invention operates as follows: Bundles 15, 15', 15" having a fixed number of printed sheets are dropped one after another upon the row of free rolls 18, 18, 18" in the space limited by the lateral guide plates l6, 16', front guide plates 28, 28' and rear guide plates 30, 30' as seen in FIG. 6. When the predetermined number of bundles accumulated and a stack has been formed, the turntable is rotated as far as I. In this instant, the front and rear guide plates 28, 28 and 30, 30' swing outward around their vertical axles 29, 29' and 31, 31' respectively to pass the protruded edges of the turntable; and the relay roll 21 is dropped down as shown with chain lines in FIG. 3 so as not to block the passage of said table.

When a stack has been formed by the accumulation of bundles, it is then transferred outward. In this instant, the turntable 11 is fixed on a definite position and the relay roll 21 is raised to the upper position by the action of the oil cylinder 24. At the same time front guide plates 28, 28' swing toward the stack pushing it rearwardly. In this instant, the rear guide plates 30, 30' are already raised to their upper position. Therefore the stack is transferred upon the moving transferring rolls 20, 20, 20". This action is repeated automatically and continuously by any prior art electric control means.

As this invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, the present embodiment is therefore illustrative and not restrictive, and since the scope of the invention is defined by the appended claims, all changes that fall within the metes and bounds of the claims or that form their functional as well as conjointly cooperative equivalent are therefore intended to be embraced by those claims.

I claim:

1. In combination with an apparatus for stacking and transferring bundles of printed sheets in super high speed rolling press where a predetermined number of bundles is accumulated upon a turntable, said bundles being arranged in opposite direction to each other and to form a definite stack, a rotatable partly circular formed turntable having straight edges at the front and rear side thereof, means for rotating said turntable, a pair of front guide plates pivotably mounted vertically adjacent to said straight edge at said front side and acting to guide the dropping bundles as well as being swingable about their vertical axes to allow passage of any protruded portion of said turntable and to push the stacks out, a pair of rear guide plates pivotably mounted vertically adjacent to said straight edge at said rear side and acting to guide the dropping bundles and swingable around their vertical axis to make passage for any protruded portion of said turntable and being movable so as to raise up when the stack is to be transferred from said turntable, and relay rolls which are swingably mounted so as to swing down out of the passage of said turntable as it rotates and transfer said stacks from said apparatus when pushed by said front guide plates.

2. The combination of claim 1 wherein said relay means are rollers which are synchronized for movement below the protruded portion of said turntable.

3. The combination of claim 1 including means for synchronizing said front and rear guide means with the rotation of said turntable.
