Abstract

With the aid of suitable transfer devices, special slide holders or commercially available types of holders are rearranged in a space-saving fashion from a compartmentalised change magazine into a storage box and vice versa.

Description

Storage devices for slide frames have been around for a long time known. However, they usually have the disadvantage that they either have space consuming (Leitz change magazine; slide transfer magazine Pat. 12 48 975), or are cumbersome to use, because the slide frames are individually, by hand, from a change magazine to a "box folder for slides" (Pat. 1 15 495) have to be decanted.

The task of the new system is to have a minimum of work and effort To create space. There are several possible solutions for this goal of which four are described in the following text.

I. The following system consists of the four components ( Fig. 1)

• Slide frame,
  Exchange magazine,
  Transfer housing and
  Storage box.

The slide frame differs from the commercially available model in that it has a groove on each outside. With the help of these grooves, the Slide frame over two webs that engage in the grooves and an inclined plane form, be lifted out of the change magazine, then in a storage box to slide.

The lateral guidance of the change magazine as well as the slide frame is thereby taken from the transfer housing, which the geometric conditions of the change magazine and the slide frame. In addition, the webs that are used for Formation of the inclined plane are necessary, firmly mounted in the front housing.  

For better threading of the slide frames into the guide bars, are on Bottom of the decanting case fixed two webs, which the frame from below to lift.

The force required to slide up the slide frames on the inclined plane is required, results from the translational movement of the change magazine in the transfer housing. A critical point is reached when the last slide frame has left the interchangeable magazine, because now there is no strength left the translational movement of the change magazine can be obtained. In order to this slide frame also runs up the inclined plane, the transfer housing, or the complete system, as far as ge relative to the gravitational acceleration sector that, from a physical point of view, the slide frame is an inclined plane slides down until it arrives in the storage box. The empty The exchange magazine is placed under the storage box in the transfer magazine guided. The storage box filled in this way can now be removed from the transfer housing taken and archived.

With a 2 mm thick slide frame, the space saving is compared with the transfer or Leitz change magazine, approx. 60%. The transfer process is done in a few seconds with skilful handling.

To the slide frames that are in the storage box close together without Intermediate elements are arranged one behind the other, again in the change To get magazine, the slide frames must be used individually with one device be isolated from the box and then into the compartments of the removable magazine to convict. Such an isolation device can e.g. B. only with help of "potential energy".

There are four bars in the storage box that follow the slide frames Leaving the inclined plane when threading. These bridges can again form an inclined plane by the rear, closed part of the Storage box is raised. The potential energy of the slide frame will slowly greater than the frictional forces that arise on the guide bars (Overcoming static friction) and the slide frames can be used to open the  Slip box. There they are held by a holding plate that is approximately 2.5 mm in front of the opening, braked. Due to the lateral friction of the Slide frame on the holding plate prevents the frame from going through the gap slips. The reduction of lateral forces (normal forces) can be achieved by reducing the slope of the inclined plane until just the Condition of static friction occurs (compensation of the potential forces by the frictional forces). The moments caused by the non-parallel hanging of the Slide frames arise relative to the gravitational acceleration vector, are broken down, when the slide frames slide up a second inclined plane until they're parallel hang on the acceleration vector.

The ratio of the length of the two levels to each other is a function the pitch angle with the boundary condition that at the end of the second skew Level, a slide frame is vigorously isolated, d. H. he only has one Weight force pointing in the direction of the gravitational acceleration vector, and all Moments from the last two slide frames become zero.

At the end of the storage box, a spring is attached, so dimensio is niert that they filled the storage box up to the above-mentioned Stei angle increases. Will the opening of the storage box that is in front of it located holding plate is now still rotatable, and you bring the system by an impulse to the oscillation, a slide frame becomes with each oscillation isolated and falls through the gap. The system only comes to rest when the last slide frame has left the storage box. The energy that The system keeps moving from the decrease in potential energy the slide frame won (undamped forced vibration).

The slide frames isolated in this way are now inserted into a guide shaft Subject of the change magazine headed. The change magazine is also located on an inclined plane and is locked by a latch that turns into a control nut grips, protected from sliding down.

The falling slide frame opens after it is halfway into the compartment of the Exchange magazine has fallen, the lever via a lever mechanism, so the magazine can slide forward. When sliding down, the lever mechanism becomes released again, the bolt snaps into the next control groove and locks the change magazine.  

The two movements now have to be synchronized so far that the oscillation period T is greater than or equal to the time required for the slide frame to fall into the interchangeable magazine and for the magazine to slide to the next free compartment. This is achieved by a vibration damper (forced damped vibration).

All components described above are constructive in the decanting housing and the storage box included.

Variants for isolating a slide frame could be created using mechanical Devices can be realized. The lateral forces at first Slide frames act through a slider moving up and down compensated. It is located above the gap and has a stroke length that the Height of a slide frame corresponds and is either manual or with a Motor driven. This system is satisfied with only one inclined plane and a constant slope.

Solutions in which the interchangeable magazine and the Storage box does not match the holding plate and the push mechanism different, but next to each other. In addition, the potential Forces that are introduced into the system by gravity suitable machine elements are replaced (storage box / spring; change selmagazin / gearbox with motor or hand crank).  

II. This system also consists of four components ( Fig. 2-4),

• the slide frame,
  the change magazine,
  the transfer magazine,
  and the storage box.

The slide frame tapers symmetrically over one on all four sides Width of four millimeters, forty percent of its absolute thickness (two millimeters). The edges and corners are rounded.

The decanting magazine is half the height of a slide frame and corresponds in width, length and subject structure to the Leitz change magazine. The con The structural difference to the change magazine is that the distances between the individual subjects can be varied.

This is achieved by the webs of the change magazine through two plates spring segments are replaced, both of which have the geometric shape of a large one Own "H" and consist of three disc springs connected in series will. A web is therefore replaced by two disc spring segments, the the right and left side wall at the same height, arranged without connection net, each have a web length of four millimeters and through which Sidewalls are both held and guided. This segment can e.g. B. can be punched and shaped from just a rectangular spring plate. Doing so a disc spring (left or right high bar of the "H") that the The distance between the individual segments in the relaxed state is just as large is like the distance between the individual webs in the Leitz change magazine. In the ge tensioned state, the distance is reduced until it is the thickness of a Slide frame corresponds. This spring lies outside the decanting housing. Form the other two springs that are inside the decanting housing the actual jetty. When relaxed, it is so wide that the Diarah men only has a clearance of less than one millimeter (in comparison Leitz change magazine: play about three millimeters, at two millimeters thick frame). In the tensioned state, the two springs are at block length compressed, d. H. they have the width of their thickness, that of one  Razor blade corresponds.

The segments are separated from each other by a T-shaped spacer separates. They ensure that the forces exerted by a hand slide in the Both spring systems are initiated, from segment to segment up to Reproduce housing wall and that the springs that form the webs on block length together. The hand slide is at the beginning of the Transfer case, connects the two spring systems with force, is the same guided and held by the side walls like the T-shaped spacers and has a locking mechanism that enters the system by hand introduced tension forces in the frame of the decanting magazine.

The storage box has the shape of a square column, the Height and width are slightly larger than the edge length of a slide frame and the length of which is calculated from the number and thickness of the slide frames to be recorded leaves. It is divided in the middle and thus becomes two symmetrical structures share, the edges of which are shaped so that they are joined together form a firm bond.

The transfer process from the Leitz change magazine into the storage box and vice versa is done with the decanting magazine. Are the slide frame in the interchangeable magazine, the springs in the decanting magazine must match the Hand slider can be set to maximum relaxation. The compartments of the both magazines are now identical, and the decanting magazine is over the Exchange magazine slipped over. If you turn the two magazines by one hundred and eighty Degrees, the frames fall from one magazine to another. The two magazines are separated. With the hand slider, the fan spacing is reduced to its mini mum reduced, and there is no distance between the slide frames. Single Gaps have formed at the edges due to the taper. In these Gaps grab the webs. They don’t touch the frame because they’re thinner, than the width of the gaps. Half of the storage box is over the slide frames protruding from the transfer magazine, and by a Rotating one hundred and eighty degrees will drop the slide frames into the storage box. After separating, the box is closed with the second half and archived.  

III. The third system consists of four components ( Fig. 5, 6),

• 1. the change magazine,
  2. the slide frame,
  3. the subject book and
  4. the storage box.

In principle it works like System II, but has the advantage that it doesn't need a special slide frame. It is also suitable for round magazines.

The difference to System II is that the transfer magazine through a pocket combination is replaced, which is made of a plastic (or cardboard) consists. For each slide frame there is a plastic bag on the sides and / or are welded or glued to one another on the floor and thus form one Form a subject network. The combination automatically turns every bag into a bag Spring because the plastic material has a spring-like character (e.g. poly styrene). It should also be mentioned that the subject network is also in one Injection molding machine can be produced in one casting.

The storage box can hold two filled plastic bag assemblies if the slide frames do not exceed two millimeters thick It is as long as the Leitz change magazine; one of his halves can be used to clamp the plastic bag assembly while the others have already added a filled composite. To be stretched the front of the storage box is only firmly connected to the floor to the There is a gap of approximately three millimeters on the sides. So arises in front and a tongue in the back of the box, over which the first or last pocket of the composite are turned up, the bottoms of which are removed have been separated.

In the case of round magazines, the two ends are connected directly to one another (Adhesive connection, clamps); they then form a stable ring with the diameter of the respective round magazine. So in theory it is it is also possible to transfer slides from a round magazine into an interchangeable rail, since the composite is both a round and a linear structure can form.  

The advantage of this system is that there is no special one Slide frame required and suitable for both round and straight magazines is. However, it has the disadvantage that it has a slightly larger space needs because the bag bundle must also be archived.  

IV. This system consists of five components ( Fig. 7),

• 1. the change magazine,
  2. the slide frame,
  3. the storage magazine,
  4. the transfer device and
  5. the storage box.

The change magazine and the slide frame correspond to those in the trade usual types.

The storage magazine is basically structured like the guide Change magazine, but it is not so long because the intermediate bars are missing and the slide frames stand side by side.

The decanting device consists of two adjacent guides web. They are constructed in exactly the same way as the guide bars in a Leitz Slide projector and each have a feed device for the magazine and a slide frame slide, with the appropriate mechanics are coupled. The feed speeds and directions are below different. During the transfer process, the slide frame slide guides a slide frame from the Leitz change magazine through a guide bar into the storage magazine. Then the change magazine is pushed forward by one compartment and at the same time the storage magazine by one slide frame width to the rear. So that the slide frames in the storage magazine don't tip over, that's all System tilted about fifteen degrees relative to the horizontal. After the the last slide frame has left the removable magazine, the storage magazine removed from the transfer device and in a dust-tight Box archived. By changing the feed device and the slide direction the process can be reversed.

The feed speed for the storage magazine is with the help mechanical or electronic components varies and therefore each adapted slide frame thickness. The space saving is as big as in the first two systems. The advantage here is that it is not only can be used for a certain type of slide frame and that it no manual operation required.  

In summary, systems I and II are also suitable for commercially available Braun Paximat Compact magazine and for round magazines own. The basic structure remains the same, it only has to different geometrical boundary conditions of the magazines more or less Be taken into account. System IV is for everyone on the market suitable magazine system, and thus the most flexible of all systems presented, if one also takes into account that one With this device, the slide frames can also be moved from a round magazine to a grade Change magazine, or rearrange any other type of magazine.
