Description

The invention relates to a film tape container with at least two film supply spools.

Containers for storing photographic roll paper with multiple paper supply rolls are already known. In order to be able to dispense the film tapes individually in such containers, each roll of film is required a transport roller and a pressure roller serving to press the film tape against this roller is provided. Furthermore, in this known device there is a switching device in the form of a plurality of buttons attached, is acted by each on a certain transport roller in such a way that the associated film tape is advanced a small piece from an exit opening common to all tapes and so it can be grasped from the outside and pulled out further. After a certain One revolution of the transport roller then comes into operation. The key pressed remains in its depressed position after actuation and only becomes effective after cutting released, whereby the film tape is withdrawn a short distance so that it is no longer out of the Outlet opening protrudes. With this facility, it is not easily possible to produce film tapes as desired Length to pull out. It is also not advantageous that the film tapes are overcome by hand must be pulled out of the container by friction. These disadvantages are encountered with film tape containers with at least two film supply spools, optionally actuatable switching means and transport means, each film supply reel consist of a conveyor roller and a pressure roller and through the each one of the film tapes output through a common outlet opening and after Cutting is automatically moved back by a small amount, avoided according to the invention, that the conveyor rollers can be driven together and that a lifting device for each conveyor roller Lifting the pressure roller and the film tape is arranged and the lifting members individually from one Lift-off position against spring force and after loosening one that acts simultaneously for all lift-off elements Locking member can be moved into a transport position. The output of the entire desired length of a film tape is done here by driven transport rollers with which the respective Film is brought into contact by lifting members, the lifting members also pulling back of the film after it has been cut. The lifting device thus fulfills two tasks, namely a specific one Release film tape for output and, if another film tape is selected, withdraw the previous film tape. It is ensured that each only one film tape can be transported.

When the locking member is moved, all lifting members are released first, the one previously actuated returns to the withdrawal position by itself. Only then is it possible to use any lifting device to bring into transport position. The position is through the locking member when it is reset in the Starting position fixed.

To actuate the lifting devices, it is useful if a control lever is provided for each lifting device is, each with one of two notches, namely a lifting notch and a transport notch, a locking member to determine the lifting position or the transport position of the associated lifting device is lockable. To ensure that upon actuation of the locking member, d. H. when the issue of the film tape container can be switched from a specific film tape to another film tape should, it is advantageous if when moving the locking member from its locking position into its release position all control levers are moved into their lifting position under the action of a spring and only then the desired lifting device is actuated. It is advantageous if the lifting members as pivotable finger elements are formed which, when the film tape concerned is taken along, in recesses engage the transport roller.

In. In the following description, FIG. 2 will first be dealt with. This figure shows a rectangular, opaque container 10, for mounting on a wall or other vertical mounting surface with mounting arms 12 is provided. The container 10 has an inlet opening 14 and one on its front side cover 16 which can be actuated by a handle 18. On top of the container 10 is one Pawl 20, which presses the cover 16 light-tight. Inside the container 10 are adjacent to the inlet port 14. a number of hollow rollers 22 rotatably mounted on shafts 24, which in turn are mounted on U-beams 25 (See Fig. 3) are attached and arranged so that they are horizontally side by side in pairs and the pairs lie on top of each other. The rollers 22 serve as a carrier for film rolls 26, which are placed thereon and by bundles 28 are held. The film rolls 26 have different diameters and / or different emulsion layers on.

In the container 10 a number of transport rollers 30 are also housed such that each roll of film 26 is assigned a transport roller. The transport rollers 30 are used to transport a specific Film from one of the rollers 26 into one between the rear wall 34 of the container 10 and film guide plates 36 formed passage 32 through which the film is passed down a cutter 38 runs up, where it is cut into pieces of a predetermined length. The transport rollers 30 are on Shafts 31 attached and have recesses 40 (Fig. 3), preferably in the form of partial lengths smaller roller diameter. Next to each transport roller 30 are suitable, finger-like, in the Recesses 40, mating elements 42 attached to shafts 44. The shafts 44 point at their ends each have a lever 46, which are each connected to a spring 48, which on the associated lever 46 and the associated shafts 44 exert a pressure and thereby the finger elements 42 out of the recesses Seek to pivot 40 out. If the finger elements 42 are outside the recesses 40, so they touch the underside of the film of the respective roll 26 and keep the film out of contact with the associated transport roller 30, so that the film is not moved towards the passage 32. At the two walls of the container 10 are articulated at 52 guide rods 50. Between the ends of the Guide rods 50 are rotatable nip rollers 54 which rest on top of the film and press the film against the respective finger element or against the transport roller 30.

The transport rollers 30 are simultaneously by means of a crank 56 via a pawl 58 and a Ratchet wheel 60 (Fig. 5) rotated. Rotation of ratchet wheel 60 causes rotation of the lowest, referred to as the lower shaft shaft 31 and a chain wheel 62 attached to it, which is in a endless chain 63 engages, and a similar sprocket 64 is on the next higher than middle shaft designated shaft 31 so that the rotation of this central shaft 31 takes place simultaneously. One Rotation of the uppermost shaft 31, referred to as the upper shaft, takes place with the aid of another, on the middle shaft mounted sprocket 66 and a similar sprocket mounted on the upper shaft 67 connected by an endless chain 65.

ίο On the outside of the container 10 is a dialing device provided to select the desired transport roller, which a certain film of the Rolls 26 should lead into the passage 32. In the embodiment shown in the drawing, there is the selection device consists of hand-operated control levers 129 fastened at one end to the shafts 44. Pivoting one of the levers 129 counterclockwise (see FIG. 1) pivots the corresponding one Shaft 44, the finger elements 42 in the recesses 40 of the respective transport roller 30

■ be pivoted so that the pivotable guide rods 50 Bring the film into contact with the associated transport roller.

Furthermore, a first locking device is provided so that only one film with certainty Film roll is fed to the cutter. There is a slot to lock the remaining roles 137 having locking rail 131 (Fig. 1) hinged at 133 to the container 10 such that one of these Slot penetrating screw 135 limits its pivot angle. The locking bar 131 is on her inner edge 139 provided with a number of notches 141 and 142 so that each two notches for a lever 129 are provided. If the levers 129 are in the upper notches 141, the finger elements grip 42 into the recesses 40. They are outside of these recesses when the levers 129 engage in notches 142. The edge parts 144 between the notches 141, 142 have such a profile on that by pivoting the locking bar 131 all levers 129 are moved out of the notches 141, before another lever 129 engages in its detent. As a result, no lever 129 can be in the position pivot, in which the associated finger elements 42 lie in their recesses 40, as long as one Another lever is already in this position, and so only one can be used in one operation only roll of film to be driven.

A rotatable display device mounted on a stub shaft 70 outside of the container 10 by means of pins 68 (Figures 3 and 5) indicates the length of film removed from the roll of film. The display device 68 is via a friction clutch 72 through a meshing with a gear 76 Gear 74 driven. The gear 76 can be mounted on the shaft 31 or otherwise by this be driven. The indicator 68 is on its periphery with a suitable scale 78 and the length of the film removed from the rollers 26 can be read on a pointer 80 will. A small lamp 82 enables reading in the dark. The display device has in its Main part handle holes 84 so that they can be loaded by the operator in their by a stop 86

6g correct basic position can be turned back. Since the pawl 58 and the ratchet wheel 60 allow movement in one direction only, movement of the scale 78 can cause the transport rollers 30 do not move or turn backwards. The spring-loaded friction clutch 72, however, allows one

Relative movement between the display device 68 and the gear 74.

The passage 32 ends in an opening provided on the bottom of the container 10. Direct In addition to the opening, a cutting device 38 is attached, which is preferably made of the usual scissors-like Cutting knives. An immovable cutting edge 88 is on the rear of the container a bracket 90 attached, while a movable cutting edge 92 with its one end 94 (Fig. 6) a rod 100 provided with a handle 98 and attached to its other, opposite The end of 96 is pivotable. The rod 100 is between the guide rods 102 and 103 to the movable To keep cutting knife 92 in the correct position relative to the fixed edge 88. Between the top surface of the movable knife 92 and the bottom of the container 10 is located a leaf spring 105 which, together with the knife in its closed position, forms an opaque Forms closure element. The cutting device closes the passage in its closed position .32 so light-tight.

Fig. 4 shows a second locking device between the cutting device and the drive device is provided for the transport rollers to prevent movement of the drive device, when the cutter is closed and the passage 32 is blocked. The locking device consists preferably of a pawl 107 hinged to a side wall of the container 10 at 109, which normally meshes with gear 76 and prevents its rotation. On the pawl 107 a tab 111 is attached near its outer end, the one at its opposite end Approach 113 has. The tab 111 is also on a locking lever provided for the cutting device 115, which is articulated at 117 to the container 10 so that it is pivotable within the guide element 119. The bottom of the Lever 115 has a latch 123 which can strike against the front edge 125 of the rod 100, to prevent retraction of the blade 92 from the closed position. The lever 115 has at its outer end a pivotable bolt 127, which the lever by striking against a Holds projection 128 on the lower guide rod 103 in the rest position (see FIG. 7). If the lever 115 raised to its upper position, the tab 111 brings the pawl 107 out of engagement with the gear 76 so that the drive device can be operated by the crank 56.

The operation of the dispenser is as follows: The operator puts his hand on the Handle 98 of the cutting device, puts the thumb under the projection 113 provided on the tab 111 and presses this projection upwards, whereby the locking lever 115 is raised. Upward movement of the tab 111 brings the pawl 107 out of engagement with the gear 76 so that the drive device can now operate. When moving up of the locking lever 115, the catch 123 is moved away from the front edge of the rod 100, and the knife can be pulled forward to its open position so that it clears the passage 32. When the knife is withdrawn, the pivot pin 127 swings against the stop 146 and strikes against the projection 128 provided on the guide rod 103 and holds the lever 115 and the Pawl 107 in its position.

The operator now determines, if this has not already been done before, the roll of film from which a piece is to be cut off. To this end, she pulls the locking rail 131 forward, whereby at the same time the respective selector lever 129 by hand is lifted. When the locking bar is pulled forwards, the previously set lever '129 lowers up to the stops 148. The locking bar 131 is now released and the lever 129 is placed in the notch 141. As a result, the finger elements 42 are inserted into the recesses 40 of the selected transport roller 30 swiveled in, and the pressure roller 54 presses the film against the transport roller 30.

Then the crank 56 is rotated until the indicator shows that the desired length is the Has passed the cutting device, whereupon the handle 98 pushed back, the cutting device closed and the film is cut. Lower when the rod 100 hits the bolt 127 the locking lever 115, the tab 111 and the locking pawl 107 ″ move into their locking position the display device 68 is rotated back into its starting position up to the stop 86.

Now if the next operator uses the dispenser and a film from one Wants to take another role, it must change the position of the selector lever 129, whereby the finger elements 42 are pivoted out of the recesses. This will end the last cut film is withdrawn from the cutter so that the first film on the next Cut is no longer recorded.
