Description

[Detailed description of the invention] Circulation rearrangement device for sheet bundles 〔Technical field〕 The present invention circularly rearranges the east of a substantially rectangular sheet, e.g. a photographic print. related to a device for Such devices are described in WO39104991, WO39109 947 and DE-A-4118390. The present invention This is related to the improvement of equipment, and such equipment is hereinafter referred to as a "photo changer". say. Some details of the configuration are the same as those disclosed in WO37103106. etc.

[Background technology]

A conventional photo changer consists of a housing and a slider (a drawer-type member). ), the slider moves between the inner end position and the outer end position within the housing. It is possible to recover. When you pull out the slider, the east side of the photo print will appear. is left on the housing by the retaining means and the remaining print is provided on the slider. It is transported out of the housing by a multi-layer transporter. At this time, the carrier and the Prints that are carried away are those that pass over the prints left in the housing. Ru. When the slider is in its outermost position, a single print in the housing Completely cross the east side of the road and the train, and cross the side of the print near the train. Edge (one of the four sides of the square print, relative to the direction of slider movement) (sides in the perpendicular direction) are free. At this time, the movement system is inside the housing. When you move one of the prints to the other side of the east side and push the slider in, Place one print on that side of the east (from the bottom of the east to the top or ). This single print passes through the return gap between the carrier and the housing. The second transverse end is then held by a print stop within the housing.

Conventional photo changers work satisfactorily in many cases. But in case Therefore, the print remaining on the housing may get stuck when inserting the slider inside. If the slider is not moved any further, the changer may be damaged. There is.

The present invention improves known photo changers so as to prevent the worst-case scenario. The purpose is to

[Disclosure of the invention]

According to the invention, the inner transverse edge of only one print left in the housing is stopped. Capturing means are provided to ensure alignment with the tool. Here, "lining up" means inside The position of the transverse end is said to match the position of the stopper with respect to the direction of slider movement. meaning, and whether or not the inner transverse end actually contacts the stop depends on the outer transverse end. Depends on the state being used.

It turns out that the worst-case scenario described above actually occurs due to the following: did. i.e. the outer transverse edge of the sheet left in the housing, i.e. This occurs because the edge that the vessel passed last is not released, and the cause is This may be because the user pushes the slider back from the middle position rather than from the outer end position, or Or, the transporter may have left behind a second print, and that second print may have been Cover the outer transverse edge of the separated sheet to be replaced and place it in place in the transfer system. This is because the functions of If you push the transfer vehicle in this condition, the transfer delay will occur. The carriage may have pushed the one or two prints inward, causing at least If the inside transverse edge of the print to be repositioned has advanced past the stop, Put it away. Prints in such a position cannot return to the correct east side again and are It becomes crunchy. However, the inside transverse edge of the print is far from the stop. If the print is carried forward, the print will be crushed. outside Prints whose end position is pressed between the carrier and the housing are , cannot touch the stop or go under the stop. like this Print replacement is not possible in a situation of severe dysfunction, and instead an isolated Return the sheet to one end of the bundle on the side from which it was separated. The capture means according to the invention The "released" transverse edge of the released print stays in line with the stop and its Therefore, ensure that the reordering cycle is restarted on the next slider round trip.

[BEST MODE 3 FOR CARRYING OUT THE INVENTION FIG. 1 shows a plan view of the photo changer with the ceiling shell removed. ceiling shell is provided with a display window. The slider 40 is formed as a sliding member 49 and a separating rod 16. Equipped with an east holder. Rail 1 is attached to the bottom of the housing, and the spring 11 (see FIG. 2). The rails l are each covered with a retaining tape 14 and and an oscillator 4, and the oscillator 4 has a hook for holding the print to be separated from the east. 5 is provided. The photo changer movement system is a lifting bracket 46. The lifting bracket 46 includes a transverse leg 48 and a control leg 50.

Ribs 78 and 80 in pairs are useful for separating one print from the east. .

When the slider is pulled out with a stack of prints placed on the slider, the hook 5 will be placed on the slider. Hold the prints that are directly against the push the tip outward. When the slider is in its outer end position, the separating rod is attached to the housing. swing past the outer edge of the print held in the lifting bracket. the bottom of the separated print and lift it away from the rail. Ru. This causes the other, or inner, transverse end of the stop 66 to while the outer transverse termination is connected to the separation bar and the ceiling shell of the housing. is placed before the return gap defined by . Push the slider in again. The separation rod goes under the separated print and the slider reaches its inner end position. the print is placed on top of the stack. In other words, the bottom east The print is brought to the top of the stack by reciprocation of the slider.

Although we briefly explained how the changer operates, the structure for this operation is described above. It is equivalent to the prior art changer.

According to the invention, the bottom 90 of the housing includes two molded symmetrically located A socket 92 is provided. Each socket 92 supports a leaf spring 94, which The leaf spring 94 is attached to the socket by a rivet at position 90 in the figure. It is being These leaf springs are parallel to the slider withdrawal direction and vice versa. tL, whose free end 98 is bent. Also fold the fixed end of the leaf spring 94. A bend 100 is provided, and this bend 100 corresponds to the position of the spring on the socket 90. The location has been decided. After attaching the spring 94 to the bottom of the housing in this way, The lifting bracket 46 is fitted into the bearing 102, and the cross leg 48 is connected to the spring 94. It abuts between the east and east of the print placed on the rail. Push the slider completely Then, the sliding material 49 passes over the control leg 50 of the bracket and Push down the bracket and then push down the leaf spring 94. In this way, figure 2, the leaf spring 94 is placed in a "sunken" position relative to the bundle.

Figure 3 shows the slider in an intermediate position moving from its inner to outer end position. vinegar. Assume that the slider is pushed in again without being completely pulled out.

Print with separated hook formed by bent free end 98 of leaf spring 94 "Catch" the inner transverse end of 32 so that the print 32 passes over the stop 66 and then to prevent the inner end from being forced under the stopper 66 and to keep the inner end aligned with the stop 66. I will do it.

Figure 4 shows the slider slightly before the fully pulled out position, and the slider is not lifted up. The lifting bracket has already lifted the inner transverse end of the print 32 in front of the stop 66. Indicates the condition. In this state, the leaf spring 94 is loose or almost loose. Suppose that When the slider is completely pulled out, the print 32 will be free and the slider will The lift spring 52 (shown only in FIG. 5) attached to the sliding member of the The outer transverse end of the vent 32 is raised to face the return gap 7. slider return In the return stroke (FIG. 5), the print 32 passes through the return gap 7. inside the slider As the printer moves, the leaf spring 94 is pushed further by the inner bracket, and the printer located along the inner transverse end of the groove 32. However, the print 32 is inside the return gap. , so the end of the spring actually releases the print 32 and causes the print 32 to is supported by stop 66 for the remainder of the slider's inward movement. Ru.

The bent free end of leaf spring 94 securely holds the inner transverse edge of print 32. It is necessary to support them. On the other hand, these spring ends are damaged at the inner transverse end of the print 32. Its edges must be easily released as soon as they are pressed to avoid causing damage. be. As a result, the manufacturing tolerances required for such designs are limited and require large This makes it unsuitable for mass production. Furthermore, there are also the following dangers: sand Straw, even if you operate normally, i.e. the slider reaches its outer end position Even if you pull it all the way out until the east holder moves outward, It is possible to "lose" a second print adjacent to the print left in the print. There is sex. In this case, if you push the slider in, you may press it too hard and the print will not be printed. The transmitted pressing force increases, the leaf spring 94 bends downward, and the print is It curves upward and ends up crumpling.

For these reasons, the second embodiment described below is preferable. This example is mostly is equivalent to the first embodiment, and corresponding components are designated by the same reference numerals. below describe only those parts that differ in design and/or function.

A stop spring device (200>) is added to the print changer of the first embodiment. The stop spring device is hereinafter referred to as a "monitoring spring." This spring device 200 is attached to the top of the housing. It is attached to the well shell and placed in the area of symmetrical surfaces between the rails. housing The free spring end extending into the interior of the spring serves as the active part of the guard spring.

Figures 6 through 9 show "normal" reordering operations without malfunction or improper operation. Indicates the state in which In the initial position, the slider is at its inner end, as shown in Figure 6. position, with the free end of guard spring 200 bent out of the way.

When the slider is pulled out, the force applied to the free end of the monitoring spring 200 is relaxed. Then, as shown in FIG. 7, it returns to its rest or monitoring position. Figure 8 shows the slider 2 shows the relative positions of the various components immediately after the start of the inward movement of the . surveillance The spring 200 is provided with a bend 202 that, when viewed from the direction of inward movement of the slider, The bent free end 98 (the hook part for catching the print) of the leaf spring 94 placed in front. The print 32 to be replaced is already in the return gap. and is supported by a guard spring. Bend 202 over the inner transverse end of print 32 move in the direction. At this time, the monitoring spring is in its natural state and is hardly deformed. I haven't. FIG. 9 shows that the slider approaches its inner end position and leaf spring 94 is pre-loaded. Press it again with the inner lifting bracket 46 without touching the inner edge of the component. Indicates a blown state.

Figure 10 shows a malfunctioning state where two prints are separated, that is, the east holder is outside. This shows the situation when the second print is "lost" on the way to the side. This is a photo Occurs when lint sticks together due to friction; When the slider starts to be pulled out, the prints 32 move together with the prints 32 to be separated. Put it away. However, only the print 32 remains in the housing due to the hook 5. the Meanwhile, the second print is moved away from print 32 and placed along the slider for a certain length. carried over a long distance. Therefore, as shown in Figure 10, the slider must be completely pulled out. The outer transverse edge of the print 32 cannot be lifted off the rail even if the print 32 is installed.

The reason is that the overlapping second print 204 cannot be pressed under the separation rod. This is because it becomes an obstacle. In contrast, the inner transverse end of print 32 is shown in FIG. By the same method as shown, it has already been moved to a position facing the monitoring spring 200. being lifted up.

As mentioned above, in such a situation, at the beginning of the return stroke of the slider, the A large pressing force is applied to the print 32. Furthermore, the force is downward Contains tropic components. As a result, the resistance of the monitoring spring 200 is insufficient and the print 32 The inner transverse end cannot be supported, for example, as shown in Figure 12, the guard spring 200 is deflected. The inner transverse edge of the print 32 extends downwardly along the guard spring 200. It slides, is caught by the catch hook 98 of the leaf spring 94, and is pulled downward.

As mentioned above, under normal operating conditions, these hooks should not touch the print edge. do not have. However, in the event of malfunction or improper operation, these hooks may The lint end is not separated (this point differs from the first embodiment). For this reason, the hook is bent. It can be too low or too high, and can capture multiple print edges. It may be as high as possible.

In the second embodiment described above, the fixed stop 66 is not superfluous. . The reason for this is that in the inner end position of the slider as shown in Figure 6, the monitoring spring does not move. Without the stop 66, the print 32 connects its end to the separation rod and the housing. This is because it cannot be stopped between the ceiling and wall of the room. When the monitoring spring 22 passes It is not appropriate to provide large and deep recesses in the separating rod to allow the separation rods to pass through. The reason is , because the separation rod is subjected to large stress. for the small stop 66 to pass through. It is good to provide similar small depressions.

FIG. 13 shows a perspective view of how to attach the monitoring spring 200 to the ceiling shell 206. FIG. 15 shows a cross-sectional view. The monitoring springs are two separate overlapping springs 200a. , 200b, each having a recess 208, and this recess 208 It interacts with a recess 210 in the well shell to position the guard spring assembly. spring The free end extends through an additional recess 212 in the ceiling shell. The top surface of the spring 200a is It fits tightly against the ceiling surface of the inner frame 214 of the ceiling shell. ceiling shell The inner frame 214 of the , covered by an externally fitted transparent viewing window 218 (partially shown).

Using two separate springs 200a, 200b allows them to slide against each other and lean backwards. I can wam. However, there must be sufficient resistance to hold the print 32. There is.

Thus, the second embodiment includes a detection system, which detects the print When the print returns to normal and is placed in the gap position, the spring device 200 is applied to the print. By detecting whether contact has been made and transmitting a small force, the spring device can be moved back to the slider. direction, or if the abutting print is pressed under the separation bar. It is possible to detect whether or not the object is being moved and transmit strong force in that direction.
