Description

The present invention relates to a device for transporting a diagram board to and from a recording position in a recording device in which the diagram board can be inserted through a slit.

Prior Art When it is important to have a quick overview within a limited time in data detection, so to speak, instant information (Sofort Information), data is often detected in a distributed manner and presented in a directly readable manner, that is, recorded. is essential in the technical field of This has the possibility of self-management through on-site data recording, immediate involvement in the production process and monitoring by an anonymous data processing device remote from the workshop. This also applies to the psychological effects of people who do not need to feel that they are in a manufacturing machine, for example. Furthermore, the records are personal, i.e. they include an individual's attendance or working hours, and these may have to be recorded in various locations, so that there is no substantive location other than the diagram board. There is no record carrier.

Such complex recording issues are a problem, for example, for vehicles in the transportation industry. Here, the diagram board is used as a record carrier that allows drivers to change places and vehicles to change places, on which important data are recorded at the correct time, and where this record carrier can be used by operating personnel and management authorities without any technical assistance. can be read by

Previously, attempts were made to replace the diagram board with a data card assigned to the driver with a data memory, which had a built-in electrical memory. In this case, if the stored data is to be visualized, it is necessary to make an indirect and time-displaced representation on the document as an evaluation, which means increased costs and also the possibility of data errors. at least with the risk of transmission disturbances, and the documentary value of such representations is therefore questionable compared to a directly readable record on a diagram board.

The reason why diagram plates are often not considered as actual record carriers is not the limited recording range or limited resolution possibilities in many applications, but generally the troublesome replacement of the diagram plates. As is well known in conventional recording devices that use a diagram board as a record carrier, in order to replace the diagram board, open the flap or cover, remove the fastening member that holds the written diagram board in place, and remove the diagram board. It is then necessary to take it out of the device, insert a new, unmarked diagram plate into the centering and driving rod, operate the fixing and clamping elements again, and close the cover again.

Such a charging process can, of course, be carried out incorrectly or if the diagram board or its sensitive recording layer is damaged due to improper handling, and if the cover is opened, access to the recording mechanism may be compromised. There is a danger that this recording mechanism could be manipulated, for example, with the intention of deception.

It has therefore been proposed to provide a recording device adapted for use with a diagram board with a slot which can be inserted through the diagram board and with a centering and fixing device which can be operated from the outside (West German patent no. 1266036 specification).

Such a recording device has the advantage of being relatively flat, which makes it possible to meet today's demands for easy integration into instrument and control panels.
Moreover, it can be used universally as a recording module. However, there are demands regarding the operability of modern recording devices, in particular the handling of record carriers, which cannot be met by the recording devices described in the above specification. Apart from the fact that the centering of the diagram board must be carried out by hand, which means that there is a risk that this action may be forgotten, the loading of the diagram board also depends on the personal attentiveness of the operator with this device. . Among the disadvantages is that the diagram board must be moved by hand to the recording position. This means that if the inserted diagram board must not protrude from the device, the diagram board can no longer be gripped sufficiently at the end of the insertion movement, i.e. it has to be pushed in with a finger, but the final This means that it must be accessible from the outside.

Problem to be Solved by the Invention It is an object of the present invention to provide a recording device in which a diagram board used as a record carrier is inserted and taken out through a slit, and to improve the handling of the diagram board and, in particular, to improve the handling of the diagram board and, in particular, to and positioning should not be dependent on the operator's personal attentiveness.

Means for Solving the Problem The above-mentioned problem is solved according to the invention by the features set out in claim 1.

Embodiments According to a preferred embodiment, the transport member is driven by an adjusting motor, which is driven by a photosensitive sensor which can be switched by the diagram board when the diagram board is inserted. , and can be controlled by key operation when taking out the diagram board. A two-armed lever is provided as the transfer member, which can be pivoted in a plane parallel to the path of movement of the diagram board, and which is moved by means of a roller attached to the arm and used as a driver. It is adapted to engage into the travel path of the plate. A receiving chamber constituting a movement path for the diagram board is provided, which is accessible from the insertion slit and includes two guide walls parallel to the diagram board and at least one end wall serving as a guide member for the diagram board. It consists of

Effects of the invention The advantage offered by the device according to the invention is that the diagram board to be inserted can be removed from the hand while being inserted into the insertion slot and is automatically brought into the recording position, yet the diagram board is no longer accessible from the outside. It is to be brought to a recording position that is not.

Furthermore, it is advantageous that the insertion process according to the invention does not come into contact with the recording layer of the diagram board, and that the positioning of the diagram board always takes place with constant precision. In this case, the invention makes use of the rolling properties of the diagram plate, i.e., even if in this situation the angle of action is unfavorable and the force component acting in the transport direction is small, the transfer lever will not move the diagram when inserting the diagram plate. Immediately after the center of the plate passes through the insertion slot, it acts on the circumferential surface of the diagram plate. Therefore, even if the diagram board still protrudes to a significant extent from the insertion slot, it can still be transported using the device according to the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The functional diagram in FIG. 1 shows the invention in a state in which a manually inserted diagram board 1 (which switches, for example, a photoelectric sensor 2) initiates the automatic transfer of this diagram board. A transfer device is shown. The transfer takes place by means of a two-armed lever 3, which is supported on a shaft 4 and is pivotable in a plane parallel to the path of movement of the diagram board 1. The lever 3 is drivingly connected to an adjustment motor (not shown in FIG. 1) in a force-transmissible manner (idle gear 6) via a segment gear 5 configured in one arm. Furthermore, tongue pieces 7 and 8 are integrally formed on each arm of the lever 3, and the lever 3 is connected to the circumferential surface 9 of the diagram board 1 via the tongue pieces.

inserted within. The accommodation chamber 12 has an insertion slit 13
The end wall 14 is provided between the insertion slit 13 and the recording position (not shown in detail) and used for guiding the diagram board 1.

Diagram board 1 with lever 3 shown in FIG.
When the tongue piece 7 is turned counterclockwise at the insertion position, the tongue piece 7 acts on the circumferential surface 9 of the diagram board 1 as described above. Therefore, diagram board 1
is supported on the end wall 14 of the storage chamber 12 and is rolled into the recording position after further movement of the lever 3. The recording position is determined by a switch 15 cooperating with lever 3. If the diagram board 1 is to be removed again, the adjusting motor is reversed by actuation of the appropriate signal generator, ie the lever 3 is moved in the clockwise direction. In this case, the tongue 8 acts on the circumferential surface 9 of the diagram board 1 and the diagram board 1 (which again
(rolling or sliding along the end wall 14 of 2) into the removal position. The removal position is determined by another switch 16. The switch limits the movement of lever 3.

FIG. 2 is a front view of a recording device equipped with an advantageous embodiment of the diagram board transfer device according to the present invention. Inside this recording device, diagram board 1 is placed on front board 1.
It can be inserted through an insertion slit 13 formed in 7 and having a grip recess 18 . By means of the lock 19 it is possible to control, for example, a locking element assigned to the insertion slot 13, so that the recording device (the casing is designated by the reference numeral 20 in FIG. 3) can only be operated by a range of qualified personnel. It is possible.
FIG. 2 also shows a key 21, which is arranged on the front panel 17 of the recording device and is preferably constructed as a luminous key.
It is shown. By means of this key, it is possible to start sending out the above-mentioned diagram board 1.

In a preferred embodiment, the receiving chamber 12 has a plate 23 on an intermediate bottom plate 22 which serves as an assembly plate.
It is structured by the people assigned to it.
The side surfaces of the intermediately integrated strip 24 are end walls 14 for guiding the diagram board 1. In contrast to the principle example of FIG. 1, the diagram plate 1 in the recording position is assigned a roller 25 arranged in a suitable recess in the strip 24, the axis 26 of the roller being connected to the intermediate bottom plate 22 and the plate 23. It is supported between
Moreover, the peripheral surface of the roller slightly protrudes into the housing chamber from the end wall 14. Furthermore, it is also possible for the end wall 14 to be interrupted by a plurality of rollers or to be constructed by a row of rollers.

Furthermore, as can be seen from the embodiment according to FIG.
Rollers 29, 30 are supported in the housing, and the rollers pass through the storage chamber 12 and engage therein. For this purpose, appropriate cutouts 3 are made in the plate 23 and the intermediate bottom plate 22.
1 and 32 are formed. Therefore, the diagram board 1 in the recording position is moved by three rollers 25, 2.
Guided times are between 9 and 30. Furthermore, the lever 3 carries a roller 34 which is rotatably mounted on a shaft 33 and is electrically connected to a slide 36 under the action of a tension spring 35 acting on the lever 3. A slide 36 formed with a control cam 37 cooperating with a roller 34 supports a rack 38 and an adjustable supported ramp 39, which ramp is provided with an oblique plane 40. The slider is movable with additional rollers 41, 42 on one side.
and a guide stand 45 and gear pairs 46, 47 on the other side.
and cooperates with switches 15 and 16 that determine the recording position or the take-out position. The additional rollers 41, 42 are supported on shafts 43, 44 fixed in the plate 23, and one gear 46 of the gear pair 46, 47 is meshed with the rack 38.

Gear 4 of gear pair 46 and 47 supported on shaft 48
7 is another gear pair 50 supported on the shaft 49;
It is connected via 51 to a worm 53 disposed on the shaft (not shown) of an adjustment motor 52 so as to be able to transmit force.

Instead of the photosensitive sensor 2, other switching means may also be arranged, for example a simple contact switch, which cooperates with the sheet inserted into the receiving chamber 12.

Although not included in the transport device according to the invention, it is further noted for the sake of completeness that the arm 55, which is pivotably mounted in a bearing bridge 54 formed in the intermediate base plate 22, is connected to the driver 56. It cooperates by means of a power transmission connection with a lamp 39 via which it can be controlled, ie raised and lowered. Arm 55 is diagram board 1
It supports a core rod 57 corresponding to the centering and entrainment opening of , which core rod is rotatably supported on a shaft 58 fixed to the arm 55 and is driven in a suitable manner, for example in a timely manner. . A slit designated by 59 in the plate 23 is used for accessing the diagram board 1 through which the recording mechanism is inserted.

If the selected recording method requires contact between the recording mechanism and the diagram board, the recording mechanism as well as the centering and entrainment member must be lifted and lowered from the slit when inserting and removing the diagram board. First, this is preferably carried out by means of a transport device which is used for positioning the diagram board. In this case, when taking out the diagram board, it must be lifted before the transport of the diagram board begins, and conversely, the diagram board is already in the recording position before the centering/carrying member and the recording mechanism are lowered. must be maintained.

Whereas the sectional view of FIG. 4 is used merely to complete the illustrated embodiment, but also reveals the particularly low structural height of the device according to the invention, the cross-sectional view of FIG. The principle diagram shows an embodiment in which the diagram board can be removed even when the current has stopped.

In this embodiment the lever 3 is coaxially supported,
Similarly, it is connected to a two-armed control lever 60 via a spring 61. For example, another spring (transfer spring) 64 that acts on one arm 62, which is used to raise and lower the centering/carrying core rod 57 in cooperation with a ramp 63 assigned to the arm 55, drives the transfer when the diagram board 1 is taken out. Acts as a member. The other arm 65 of the control lever 60 is connected to the spring 6
In cooperation with a pawl 67 under the action of 6, the pawl can be actuated by means of a spring-resiliently supported key 21 via a suitable coupling member 68. Additionally, the arm 65 has an adjustment motor 52 (not shown in FIG. 5).
A driving body 70 arranged on a disk 69 driven by the actuator 70 acts.

When transferring the diagram board 1, the control lever 6
0 and at the same time the lever 3 connected to this control lever 60 is pivoted by means of a driver 70 which moves in a counterclockwise direction from the position indicated by the dotted line, i.e. first the lever 3 is brought into the recorded position on the diagram board. It is brought up to a stopper 71 that defines the. Arm 62 of control lever 60 and lamp 63
After a certain overstroke which lowers the arm 55 and thus the centering and entraining rod 57 in cooperation with the control lever 60 or the arm 65, the pawl 67
It is locked by. The spring 64 is tensioned and the driver 70 is returned to its starting position by means of a one-turn mechanism of the disk 69.

When the diagram board 1 is to be removed, the recording mechanism is first lifted from the diagram board 1 by operating the key 21 (not shown) based on the certain play of the coupling member 68. The control lever 60 is then unlocked, the spring 64 is released, and the control lever 60 is returned to the stationary driver 70, in which case the arm 55 is first lifted before the diagram board 1 is transferred. It will be done.
