The Moschino relates to a machine that can be added. In this known mosquito, a large and stack of flexible objects is used, as in the case of a number of pneumatic motors and
With a counting device and a stacking device, such a machine is not suitable for the joUocli lur juriiti; device and with a double series of stacking sheets, speeds of 72,000 bxemmajcn per the same dispatch on each of two final hours. With the Deloscn conveyors, which are known to machine pressure fluctuations in the vertical direction, are arranged in such a way that the stacking plates in the neighboring sections evacuate each other and are assigned to the pneumatic motors Claim times of these moles of the conveyor track are aligned with one another, and with io gates, and this is compatible with a precise rate of control with vertical guides that can be arranged between the. At high speeds with adjacent parts of the conveyor tracks at the rare, sudden stops of the compressed air cylinders are arranged to form stacking blocks, the tunnels damaging the feed. ,
The invention is based on the object of providing a device for driving the conveyors, which are shaded by 15 machine, the cmc higher hourly the payment device can be operated to synchronously process the production rate.
To move the conveyor a predetermined distance, according to the invention, this is achieved because when a predetermined number of objects the drive for the conveyor is counted by a urine motor, such that a pair of stacking sheets is used to catch the conveyors over a bin , which is connected to the feeder feeder, which has a release mechanism and a timer, by means of which cams and a first and second locking lever which can be retracted after a predetermined delay and which can be moved a certain distance from one another by a second predetermined distance The scope of the draw is that the stacking sheets that carry a stack are arranged in cams, that the control device is moved into non-adjacent sections of the conveyor tracks as the drive * of the conveyors, a first control device to drop the stack and that it has, with the connected to the first locking lever a pick-up station, which is below the adjacent and controllable by the counter, is arranged around the first Spcrr conveyor tracks and further with a lever retract when the count of a pre-ejector. certain amount has ended and the r-orderer

on (Fig. 1). The right set of chains 28 extending around upper and lower sprockets that are fixedly mounted to the common upper and lower shafts 32a and 32b, while the left chain set to herumerstreckt in a similar manner around sprockets attached to upper and lower shafts 34 a and 34 b mounted are. The shafts 32 ″ and 32 b and 34 a and 34 b are rotatably mounted in the frame of the machine, not shown. A pair of drive sprockets 36 is mounted on the upper shafts 32 a and 34 a and these drive sprockets are connected by an endless chain 38, which also extends around a pair of guide sprockets 40 on the right side, around the shaft 32a with respect to the shaft 34a reversed to turn.

Although not specifically shown, it should be noted that the guide sprockets 40 are mounted such that their position relative to one another can be adjusted in order to be able to change the position of the right chain set 28 with respect to the left chain set 30. In this way, the guide or surface parts of the corresponding chain sets can be brought into a precisely aligned position. The shaft 34a is connected to a periodically moving drive source 42 and this drive source can have a continuously driven electric motor Af 2, a mechanical single-turn clutch 44 which has a release cam 44a and this drive can also have an electromagnetic brake BR 2, as shown schematically shown in Fig. 8a.

Each of the right and left chain sets 28 and 30 has four equally spaced apart Stacking surfaces or stacking plates 46. These stacking plates of the right chain set 28 are mirror images formed to those of the left chain set 30. The sheets 46 are along the corresponding Chain sets arranged so that when the cooperating sheets are on the adjacent vertical sides of the left and right chain sets are located as described above in such a way can be set that the interacting sheets towards each other in the extend essentially in one plane to form stack dividing platforms, as in particular in Fig. 1 is shown.

With reference to FIGS. 2 and 3 it should be noted that the sheets 46 are at an angle can extend up to the entry side of the machine. Each sheet has a wedge-shaped Side section 46 a, which is bent upwards, in a plane perpendicular to the plane of the sheet. The plates 46 are on special console-like links 28 a and 30 a of the chain sets 28 and 30 secured by having the side sections 46 along the top edge (Fig. 3) with these links are riveted.

The opposite ends of the side sections 46a are shaped to extend perpendicular to the cutting section and away from the metal sheets. Guide rollers 46 /; are mounted at each end portion so as to extend outward therefrom. The axes of the guide rollers 46 lie essentially in the same horizontal plane as the fastening points of the desk sections 46a on the consoles 28a or 30a. The higher end portion of the wedge-shaped side part 46o has a second guide roller 46 c , which is installed on this section in vertical alignment with the shaft 46 on it. The rollers 46fe and 46c extend into it ii guide channels 48 which are mounted on the frame of the machine and which are shaped such that they determine a path parallel to the track of the chain be.

The supplied newspapers leave the entrance and counting section 12 and are on a together Men-acting pair of blades 46 stacked. The front

ίο ren edges of the newspapers are in vertical Direction aligned along a pair of rear guides 50 while the side alignment the newspapers through inwardly angled side guides 52 takes place. As shown, di ( Blades 46 can be recessed in a suitable manner in order to leave the guides 50 and 52 free when di < Shovels move with the chains.

A stack receiving table 4 is arranged immediately below half of the stack section 2. The table A

ao has a pair of upwardly extending sides parts 54 that have outwardly bent upper ends. A narrow segment of a conveyor 5f of free-running rollers is mounted on the table 4 and extends between the open ends that are in front the side parts 54 are limited. These open ends are somewhat narrowed by elastic outlet wedges, which are attached to the sides 54. The outlet wedges 54a are made from a light spring metal and serve to stabilize the stack somewhat when it leaves the table 4.

It is often desirable to make complete stacks made up of two or more stacked sets the stacking station. To compensate for the wedge shape of the individual stacking sets, it is desirable

worth seeing, successive stacking sets by 180 ° to twist against each other. In order to make this possible, the table 4 can be rotated within the frame of the machine stored.

The rotary switch of the table 4 is carried out by the

Output shaft of an associated cam-operated switching drive 58, which is operated by an electric motor M 3 via an electromagnetic clutch CL 3 and a brake BR 3 (FIG. 8). The cam operated gearbox is a commercially available mechanism selected according to the desired speed and acceleration conditions and is classified as a modified sine drive with two stops and a 270 ° shift period. In short, this classification means

cation that the output shaft of the drive 58 over 180 ° for each individual revolution of the input shaft is switched, of which 270 degrees of rotation are used to accomplish the drive, while the remaining 90 ° represent a dwell time to control the drive. The acceleration the output shaft during its 180 ° switching movement is designed in such a way that it is continuous and this acceleration can be plotted as a curve that closely follows a sinusoid

approximates as shown at b in FIG. The output shaft speed achieved by this acceleration is shown as curve α in FIG. 9 and it can be seen that extremely smooth and continuous operation is achieved

which enables the table 4 to be switched quickly without the newspapers lying on the paper being confused or destroyed will. Additional detailed description

To fulfill chains at a distance of half a chain length in such a way that the ejector is required, a second was attached so that these are located along the center lines between the conjugate, cam-actuated switching drive 78 and the left and right shafts of the corresponding. The drive 78 is very similar to the Anchenden chain set in FIG. 4 illustrated drive 58 for the table 4 set up with the normal off position extending outward.
