[0003] Furthermore, the document DE 19 05 581 U discloses a device for collecting pieces of conductor wire which have been cut to length by a machine and stripped at the ends for use in electrical circuits, characterized by a collecting container which extends in the direction of the resulting wire ends and whose cross-section has a V-shaped or U-shaped profile and in which a length stop for the wire ends is adjustable and on both sides of the container cams are provided which are triggered by the cutting tool of the machine or by tappets arranged thereon.

[0004] The technical object of the present invention is to improve the state of the art in such a way that safer and simpler maintenance, operation and operation are enabled.

[0005] The technical problem is solved by an object having the technical features according to the independent claim. Advantageous embodiments are the subject of the dependent claims, the description, and the drawings.

[0006] According to one aspect of the invention, the technical object of the invention is achieved by a partially automated stripping device for assembling conductors surrounded by an insulating sheath, the device comprising a stripping unit, a screen, wherein the screen shields the stripping unit from a surrounding area of ​​the device, a container space arranged below the stripping unit, a collecting container arranged in the container space, wherein the collecting container is designed to receive severed sections of the sheath and / or severed sections of the conductor, a positively opening contact, wherein a motor current operating the device is separably closed via this contact, characterized in that the device has a safety unit assigned to the collecting container, wherein the safety unit has a removal protection device and an insertion protection device,When the collecting container is removed from the device, the positively opening contact is separated by means of the removal lock, and the insertion lock prevents the collecting container from being inserted into the device and thus the positively opening contact from closing again if the cover is removed.

[0007] Advantageously, the collecting container can be removed from the device at any time, and the device is deactivated as soon as the collecting container is removed. If, for example, the cover is removed for maintenance purposes, reinsertion of the collecting container and thus restoration of the device's functionality is prevented. The insertion protection can be designed, for example, as a mechanical lock that prevents reinsertion of the collecting container and thus release of the motor current when the cover is removed. The cover can, for example, comprise a blade holder plate or a cable clamping plate, which is arranged in particular above the collecting container and can preferably be designed to protect against injuries during intervention.

[0008] In a technically advantageous embodiment, it is provided that the removal lock has an actuating arm and an actuating link formed on the collecting container, wherein the actuating arm and the actuating link form a positive engagement and wherein the actuating arm is designed to separate the contact.

[0009] According to the invention, the cover protects against accidental contact and, as a result, against injuries, particularly during service or maintenance work on the device. Furthermore, the actuation arm can be designed, for example, as a slider or similar device.

[0010] Furthermore, the invention provides that the collecting container can be designed, for example, as a waste tray.

[0011] This advantageously allows for a simple design option, which simplifies production, minimizes costs and can further improve operation.

[0012] In a further technically advantageous embodiment, it is provided that the actuating arm is always firmly connected to the actuating link by means of the positive engagement until the collecting container is removed from the device.

[0013] Advantageously, a process-reliable guidance of the collecting container can be ensured over the entire movement distance that the collecting container travels during insertion or removal, which can have an additional advantageous effect.

[0014] Furthermore, in a technically advantageous embodiment, it is provided that the removal protection device comprises a pressure opener, so that by means of a pressure effect, in particular a pulse-like pressure effect, on the collecting container in its insertion direction, subsequent removal of the collecting container against the insertion direction is possible.

[0015] For the purposes of the invention, a push-to-open device is a component that, for example, utilizes a spring-loaded mechanism to eject the collection container according to the "push-to-open" principle. For example, a spring can be tensioned upon closing, which is held tensioned, for example, by a magnet, until it releases the stored spring force upon opening, facilitating removal when the collection container is ejected.

[0016] Advantageously, existing technology can be used cost-effectively in production and the use of this technology can also simplify and facilitate operation.

[0017] In a further technically advantageous embodiment, it is provided that the actuating arm is arranged in the longitudinal direction and at an angle relative to an insertion direction.

[0018] This advantageously allows for a compact installation space, furthermore a transverse component of the movement is available and a form fit by means of a diagonal movement can be achieved.

[0019] In a further technically advantageous embodiment, it is provided that, in addition to the actuating arm, a gear element and a pressure element for actuating the pressure opener are provided, wherein the actuating arm, in engagement with the gear element, forms a path transmission such that an effective range of the pressure opener is translated relative to an effective range of the positive engagement.

[0020] This allows for greater flexibility in design during production, enabling a wider range of applications and more cost-effective production.

[0021] Furthermore, in a technically advantageous embodiment, a switch is provided on the safety unit, which enables deactivation of the machine, in particular via a switching gate on the actuating arm.

[0022] This can also advantageously ensure simpler and more reliable operation of the device.

[0023] In a further advantageous embodiment, it is provided that a switch is provided on the safety unit, which enables deactivation of the machine, in particular via a switching gate on the pressure element.

[0024] This can also have the additional advantage of making the device easier and more reliable to operate.

[0025] In a further technically advantageous embodiment, it is provided that the collecting container has an additional release element, in particular an electrically conductive closing element, for detecting the presence of the drawer, wherein the release and / or the closing element preferably dips into an opening provided for this purpose in the security unit.

[0026] This can also improve the device’s usability.

[0027] Further embodiments of the invention are illustrated in the figures and are described in more detail below.

[0028] They show: Fig. 1 is a schematic side view of a stripping device in a first state; Fig. 2 a schematic representation of a bottom side of the stripping device in the first state; Fig. 3 a schematic side view of the stripping device in a second state; and Fig. 4 a schematic representation of an underside of the stripping device in the second state.

[0029] In a summary of the Fig. 1 to 4 schematically illustrate a semi-automated stripping device 1 for assembling conductors surrounded by an insulating sheath. The device comprises a stripping unit 2 and a shield 3, wherein the shield 3 shields the stripping unit 2 from a surrounding area 4 of the device. A container space 5 is arranged below the stripping unit 2. The device further comprises a collecting container 6 arranged in the container space 5. The collecting container 6 is designed to receive severed sections of the sheath and / or severed sections of the conductor.Furthermore, the device comprises a positively opening contact 7, wherein a motor current operating the device 1 is separably closed via the positively opening contact 7, wherein the device 1 has a safety unit assigned to the collecting container 6, wherein the safety unit has a removal safety device 9 and an insertion safety device 10. When the collecting container 6 is removed from the device 1, the positively opening contact 7 is separated by means of the removal safety device 9, wherein the insertion safety device 10 prevents the insertion of the collecting container 6 into the device and thus, if the cover 3 is removed, prevents the positively opening contact 7 from closing again.

[0030] This allows the collection container 6 to be removed at any time, thereby disabling the device. If, for example, the cover 3 is removed for maintenance purposes, reinsertion of the collection container 6 and thus restoration of the device's functionality is prevented.

[0031] Furthermore, a synopsis of the figures shows that the removal lock 9 has an actuating arm 11 and an actuating link 12 formed on the collecting container 6, wherein the actuating arm 11 and the actuating link 12 form a positive engagement, and wherein the actuating arm 11 is designed to separate the positively opening contact 7. The actuating arm (11) is always firmly connected to the actuating link 12 by means of the positive engagement until the collecting container 6 is removed from the device.

[0032] The removal lock 9 comprises a pressure opener 13, so that by applying pressure to the collecting container 6 in its insertion direction 14, subsequent removal of the collecting container 6 is possible in the opposite direction to the insertion direction 14. The actuating arm is arranged in the longitudinal direction and angled relative to the insertion direction 14.

[0033] Advantages include, among other things, process-reliable guidance of the collecting container over the entire movement distance, as well as the possibility of a compact design, whereby an additional transverse component of the movement is available and a resulting form closure can be achieved by means of diagonal movement.

[0034] In addition to the actuating arm 11, a gear element 15 and a pressure element 16 are provided for actuating the pressure opener 13. The actuating arm 11, in engagement with the gear element 15, forms a path transmission such that an effective range of the pressure opener 13 is transmitted relative to an effective range of the positive engagement. Furthermore, a switch 17, comprising the positively opening contact 7, is provided on the safety unit, which enables deactivation of the device 1 via a switching gate on the actuating arm 11. The switch 17 is formed on the safety unit, which enables deactivation of the device 1 via a switching gate on the pressure element 16.

[0035] This can provide additional benefits in terms of more flexible design and easier manufacturing.

[0036] In the Fig. 1 and Fig. 2, the device 1 is shown in a first state, in which the collecting container 6 is partially withdrawn from the container chamber 5 and released for removal. In this state, the device is deactivated, in particular, a motor current is disconnected, and operation of the device is prevented because the positively opening contact 7, like a switch 17, is open.

[0037] In the Fig. 3 and Fig.4, the device 1 is shown in a state in which the collecting container 6 is fully inserted into the container space 5 and removal is prevented. The collecting container 6 is in a home position, and the positively opening switch for the motor current is closed. The cover 3, shown as a cable clamping plate by way of example, is screwed on, whereby the insertion lock 10, by means of a locking lever shown by way of example, releases the insertion of the collecting container 6. In other words, it is provided here that when the collecting container 6 is pulled out, a driver on the inclined actuating arm 11, designed as a slide, pulls a switching cam forward and against the insertion direction 14. At the same time, a locking pawl tilts into a position in which a gear, which can be provided, for example, in the gear element 15, is locked.Re-inserting the collecting container 6 is only possible by unlocking this latch using a key attached to the collecting container 6.

[0038] The possibility of manually inserting the inclined actuating arm 11 is not possible, which can have an advantageous effect on the user-friendliness, among other things.
