Description

BRIEF DESCRIPTION OF THE FIGURES

(1) FIG. 1 schematically shows a labeling machine with a protective element according to an embodiment.

(2) FIGS. 2A-2C show embodiments of different handles with pushbuttons.

DETAILED DESCRIPTION

(3) FIG. 1 shows a labeling machine 100 according to an example of the present disclosure. In the example shown in FIG. 1, the labeling machine comprises a carousel 101 at the periphery of which several container holders 150 are provided in which containers can be clamped. As the carousel 101 rotates, the containers gradually reach the labeling unit 140, where a label is applied to the containers at least with the aid of cylinder 141.

(4) The labels may be applied, for example, with the aid of self-adhesive labels (e.g., from continuous rolls or already cut into pieces in magazines). Alternatively, cold-glue or hot-melt labels can also be used for this purpose, which are first cut to size if necessary and then provided with glue before the labels are applied to the container.

(5) The example of the labeling machine with a carousel is not imperative. An example can also be provided in which the labeling machine is configured as a linear machine. Furthermore, not only one labeling unit 140 must be provided at the periphery or along the labeling machine, but several labeling units may also be provided, which may also apply different labels to the containers in some examples.

(6) Furthermore, the labeling machine, in the example shown here in particular the carousel, comprises a protective element 110. In the example shown here, this protective element 110 is configured as a door, whereby the door can be configured in particular as a door leaf which can be pivoted into position 111.

(7) The door leaf comprises a handle 130, which is intended for moving the door leaf or, more generally, the protective element. For this purpose, the handle 130 can be connected to the protective element via connecting elements 133 (even only one connecting element or more than two connecting elements are conceivable here), so that an operator who actuates or pulls or presses the handle in an appropriate manner can move the protective element. In the embodiment shown here, pulling the handle 130 can therefore open the door, whereas pressing the handle when the door is open will close it.

(8) According to the present disclosure, the handle 130 comprises at least one pushbutton (also called switch) 131 or 132 with which upon actuation the movement of the protective element can be released and/or blocked. In the embodiment shown here, two buttons 131 and 132 are provided, which together form the pushbutton according to the present disclosure. Upon actuation, one of these buttons may allow the opening of the protective element in such a way that a movement from the closed state is released. In this embodiment, the other button may be used to close the open door or to block the movement of the protective element when actuated.

(9) Alternatively or additionally, one of the buttons, e.g., button 131, may be used to block and release the movement of the protective element and the second button (e.g., button 132) can be used for acknowledgement. In such an example, the operator can open and close the protective element by actuating the button 131. While the protective element is open, the machine may be configured to not enable an operator to operate the machine at all. After the operator has closed the protective element (for example by actuating button 131), it can be provided that the operation of the machine is nevertheless not immediately released. Instead, acknowledgement or confirmation by the operator by pressing the second button 132 can be provided as a necessary signal for restarting the machine, so that the operator checks via button 132 before acknowledgment whether any other persons are in the area of the labeling machine or even inside the protective element and only then enables operation of the labeling machine by actuating button 132.

(10) Such a button for acknowledging or confirming that the labeling machine can be put back into operation can also be provided as a third button or switch in addition to the examples described here, whereby a first (and second) button can be used to release and block the movement of the protective element (e.g., respectively).

(11) While the protective element in the example shown in FIG. 1 is configured as a door leaf or general door, it may also be provided that the protective element is configured in the sense of a hood and movement of the protective element takes place at least in part in a vertical direction. For example, a protective element 110 may be arranged on the periphery of the carousel 101, and the protective element may be moveable upwards or downwards, substantially parallel to the rotation axis of the carousel. Such examples may be used if the space available in the plane is too small to allow doors to be opened.

(12) In such a case, the arrangement of the handle shown in FIG. 1 may be modified, as the illustrated arrangement may not be as ergonomic as other arrangements to the operator in such a way that the lift protection segment provided can be lifted. In the case of providing the protective element 110 as a lift protection segment, the handle may be arranged transversely, e.g., tilted by 90 with respect to the embodiment shown in FIG. 1.

(13) The configuration of the handle 130 as a cuboid, as schematically shown in FIG. 1, is also not to be understood as imperative or restrictive. All examples can be used here, also ergonomically more suitable ones for associated uses.

(14) In order to generally prevent slipping from the handle during the movement of the protective element, the handle may include and/or have applied thereto an anti-slip coating. In some examples, the pushbutton may also include and/or be provided with such a coating.

(15) FIGS. 2A to 2C show different examples of the handle and the pushbutton.

(16) FIG. 2A shows a handle 210 on a protective element 209, which may be an example of protective element 110 of FIG. 1. On a side facing the protective element 209 (in contrast to the embodiment shown in FIG. 1), the handle 210 has a single button as pushbutton 211. This pushbutton may be configured as a dead man's device, so that the movement of the protective element 209, to which the pushbutton is attached, is only possible if pushbutton 211 is also actuated. When the pushbutton is released, the movement of the protective element may be completely blocked. The arrangement of the pushbutton on the back or the side of the handle facing the protective element 209 may protect the pushbutton from unwanted environmental influences. Furthermore, unwanted actuation by an operator pushing against the handle may be avoided, whereas at the same time a good accessibility of the pushbutton is achieved when gripping around the handle in some manner (shown here by hand 212).

(17) In the embodiment shown in FIG. 2B, handle 220, as a pushbutton as shown in FIG. 1, comprises two buttons 221 and 223. One of these buttons may be used to release the movement of the protective element not shown here (e.g., where the handle 220 is integrated with, mounted on, mechanically or electrically connected with, and/or otherwise associated with a protective element of a machine), while the other is configured to block the movement of the protective element. Alternatively, it may also be provided that one of the buttons (e.g., button 221) allows the opening of the protective element when actuated, whereas the other button (e.g., button 223 in this case) allows the labeling machine to be closed again and then put back into operation when actuated.

(18) To make it easier for the operator to select the right buttons, a light element, for example an LED, may be assigned to each button. In the embodiment shown in FIG. 2B, this is achieved by the ring light element 222 or 224 around the button 221 or 223, respectively. This ring of light or, more generally, the light element, may light up if the subsequent movement of a protective element requires actuation of the associated button. If, for example, the protective element is in the closed state, opening is the only possible movement for the protective element. If button 221 is intended for opening the protective element or for releasing the movement required for this, the light element (e.g., ring) 222 may light up (e.g., permanently) in the closed state of the protective element. Furthermore or alternatively, it may be provided that the respective light element is only activated and flashes, for example, if a movement is attempted without actuating any buttons 221 and 223 or the wrong button (e.g., a button that is not actuatable to enable the attempted movement) is actuated. Furthermore, the light elements may include or present different colors or markings under different conditions in some examples. For example, if the wrong button is actuated (e.g., input is made to a button that is actuatable to release the protective element when the protective element is already released, or input is made to a button that is actuatable to block movement of the protective element when movement of the protective element is already blocked), the corresponding light element may flash red, whereas the light element for the correct button lights green.

(19) Other colors or signal patterns are also conceivable here.

(20) The examples of pushbuttons shown in FIGS. 2A and 2B may be provided in analog and/or electronic form. To control the release or blocking of the movement of the protective element 110, the electronic pushbuttons can be connected to a control unit, for instance the central control unit of the labeling machine, in particular a computer, which in turn controls certain, electrically controllable closing mechanisms of the labeling machine and controls the mechanisms depending on the actuation of the pushbutton.

(21) FIG. 2C shows an embodiment of handle 230 with an analog pushbutton 231, which is shown here as a single button. This button may, for example, be configured as a dead man's device in accordance with FIG. 2A and only allow the protective element 110 to move during actuation of the button.

(22) The analog pushbutton 231 is mechanically connected to a closing element 232 in such a way that actuation of pushbutton 231 is translated into a movement of the closing element 232, which releases the movement of an associated protective element at least when pushbutton 231 is actuated. Such an analog version of the pushbutton can be advantageous, as this ensures safe opening and closing or general movement of the protective element even when the central power supply to the labeling machine is switched off.

(23) The description of embodiments has been presented for purposes of illustration and description. Suitable modifications and variations to the embodiments may be performed in light of the above description or may be acquired from practicing the methods.
