Definitions

  • the present invention relates to a device for removing or branching off product segments from a product flow in the industry producing energy cells.
  • Machines for producing battery cells using drums driven in rotation are known, for example, from WO 2016/041713 A1, WO 2020/192845 A1 and DE 10 2017 216 213 A1.
  • switches are required in the production machine which a product flow from web sections or product segments, for example electrodes, separator sheets or monocells, can be separated into several possible paths.
  • the invention is therefore based on the object of providing a device for removing or branching off flat product segments from a product flow of the industry producing energy cells.
  • the device has at least one switchable delivery device which is set up to remove a product segment from the product flow as a result of a switching signal.
  • the switching signal is output by a control device, for example by the machine control. According to the invention, a switchable delivery or transfer of product segments from the production run is made possible.
  • individual product segments for example electrode or separator layers or individual monocells
  • individual test criteria can be checked for correct detection by the internal sensors.
  • the machine sensors can be tested with little effort.
  • Such sensors can also be calibrated in this way.
  • product segments with connection points so-called splices
  • product segments removed according to the invention Checking the internal sensors by comparing the internal measured values with external calibrated measuring means; Calibration of the internal sensors; Production withdrawal to check ongoing quality; targeted splice removal to ensure that these do not end up in the end product.
  • the targeted removal of individual product segments thus enables internal machine sensors to be calibrated. It also enables the product quality to be checked quickly at key process points, which would otherwise only be possible with a lot of effort by stopping and then restarting the machine.
  • a removal device can preferably lead the removed product segment out through a lock from a climatically protected area. This means that the production climate is only minimally disturbed and a time-consuming (re)establishment of the necessary climatic conditions can be avoided.
  • the machine can have one or more removal positions in the transport direction, with each removal position preferably being assigned a delivery device designed according to the invention, via which the intermediate products (segments) present at the respective production point can be removed.
  • the device preferably has a collecting device which is used to receive a product from the dispensing device strom remote product segment, for example below the dispensing device, can be arranged.
  • the collecting device has at least one collecting container which can be arranged in particular below the dispensing device and which can be removed from the machine manually or automatically, for example.
  • a separate collection container can be provided for each extraction point.
  • the collecting device therefore comprises a plurality of collecting containers that can be assigned, in particular, to different removal positions.
  • a removal request is made to the product tracking in the control device.
  • the corresponding product segment is then automatically thrown into the collection container by means of the delivery device.
  • the operator can then remove the collection container with the product segment.
  • At least part of the collecting device is preferably movable, adjustable, traversable or pivotable, in particular between different removal positions and/or out of a machine.
  • a device that can be moved laterally can be provided below these removal points, which device can include a collecting container or can itself be set up to receive discarded product segments.
  • the collection container or, more generally, a part of the collection device is specifically moved under the removal point when removal is required and can wait there, for example, for product segments to be ejected. When the moveable collection container reaches the removal point, there is a wait, for example, until the product segment to be ejected has passed the removal point.
  • the dispensing device is then activated, for example by means of an ejection valve, and the product segment is released or removed from the process flow.
  • This can be done with or without compressed air, for example also mechanically, for example by means of a comber.
  • the products then fall, if necessary, into an intermediate store (buffer device) explained further below or directly into the collecting container or the collecting device.
  • the collection container advantageously moves to a removal sluice of the machine.
  • the ejected product segment is accepted by the operator for further testing.
  • the collecting device can comprise a conveyor device, for example a belt conveyor. If a conveyor belt with a collection container is used, the removal request is sent to the collection container, for example, so that it can then move under the removal point.
  • a buffer device for temporarily storing removed product segments between the dispensing device and the collecting device. From a time point of view, it can be advantageous to provide such a buffer device under each removal point, since the movement time of a movable collection container can be longer than the time until a product segment to be ejected arrives at the receiving device.
  • the removal device can have a holding device, for example a vacuum device, for exerting a holding force, for example a suction force, on the product segment in the product flow.
  • a holding device for example a vacuum device
  • the switchable delivery device is advantageously set up to reduce or eliminate the holding force as a result of a switching signal.
  • the delivery device has at least one rotatably driven delivery drum and the holding device described above is set up to hold and transport at least one product segment by means of suction on the outer surface of the delivery drum.
  • the switchable dispensing device is advantageously set up to reduce or eliminate the suction force as a result of a switching signal. Due to the reduced or eliminated suction force, the product segment located in the delivery area of the delivery device can either fall from the delivery device due to the force of gravity, or be transferred to a receiving device to be explained later.
  • the switchable dispensing device preferably has at least one switchable valve arranged in a vacuum device for interrupting the vacuum acting on a product segment.
  • a product segment By interrupting the vacuum supply, a product segment can be released from the product flow in a simple manner.
  • a compressed air device on the delivery side which can be switched by means of a valve, for example, is provided for conducting compressed air to a delivery point of the delivery device.
  • the negative pressure existing at the delivery point can be broken and neutralized by means of compressed air for delivery of a product segment.
  • the invention can also be applied to a device for branching off product segments from a product stream of the energy cell-producing industry.
  • the device advantageously has a rotatably driven delivery drum, which is set up to hold and transport a product segment on the lateral surface of the delivery drum by means of suction force, and a rotary-driven receiving drum with at least one vacuum sector that can be subjected to negative pressure, in order to move a product segment by means of suction force to keep and transport on the lateral surface of the receiving drum.
  • the device can advantageously be controlled in such a way that, as a result of a switching signal for transferring a product segment, a higher suction force is generated on the receiving drum relative to the suction force on the delivery drum at least in a transfer area between the two drums.
  • the invention takes into account the basic functional principle of a transfer, which is based on the receiving side exerting a greater force on the product segment than the transferring side. This difference in force is advantageously generated by negative pressure of different strengths. Therefore, for the purpose of transferring a product segment, the receiving drum is supplied with a stronger vacuum than the delivering drum. To prevent a transfer for the purpose of further conveying a product segment on the delivery drum, a compressed air device on the receiving side, which can be switched, for example by means of a valve, is preferably provided for conducting compressed air to a receiving point of the receiving drum.
  • the compressed air line on the discharge side and the compressed air line on the intake side are advantageously connected in such a way that at any given time only one of the two compressed air lines applies compressed air to the assigned delivery point or intake point. These two switching positions can be used to implement a reliable switch for the product segments in the machine.
  • compressed air can be fed to the transfer point in both drums involved (delivery drum and receiving drum). However, only one side (discharge side or intake side) is pressurized with compressed air at any given time. If the compressed air is present on the receiving side, the vacuum is broken here and the product segment is transported further on the first drum (delivery drum). When the compressed air is present on the dispensing side, the vacuum is broken here and the product segment is transferred to the second drum (receiving drum).
  • the compressed air can, for example, be fed into the control bodies of the drums via a 3/2-way valve; each of the control bodies is then connected to an outlet of the valve. The signal which position the valve assumes comes from the machine control. This ensures that only one side is ever supplied with compressed air.
  • Several valves can also be provided hen to realize a transfer, for example, a valve per drum (delivery drum and receiving drum).
  • the receiving drum has at least one suction-pressure-free sector, which has no suction pressure or a suction pressure that is lower relative to the suction force on the delivery drum.
  • the rotational position of the receiving drum can preferably be controlled in such a way that the suction-pressure-free sector can be positioned in the transfer area for further conveyance of a product segment on the delivery drum, and the vacuum sector can be positioned in the transfer area for transferring a product segment to the receiving drum.
  • the invention takes into account that the vacuum level usually cannot be switched quickly enough.
  • the receiving drum is therefore designed with at least one sector where the lateral surface is not supplied with negative pressure.
  • the receiving drum As long as the product segments are to be transported further on the first drum, the receiving drum is positioned in such a way that the sector that is not supplied with vacuum faces the first. However, if a product segment is to be taken over, the receiving drum is set in motion in such a way that an area that is supplied with vacuum takes over the product segment.
  • the aspect of the invention described above relates to switches in the machine, at which the product flow of the product segments (composite units, monocells, electrode sheets or separator sheets) is separated into a number of possible paths. The decision as to which product segment takes which path is made, for example, in the machine control based on the properties or designs of the product segments. Because these divisions do not follow a fixed pattern, the transfer at the points should be switchable and activated by the machine control. The invention meets these requirements in the manner described above.
  • a further aspect of the invention relates to a machine in the energy cell producing industry, comprising at least one device according to one of the preceding claims and an electronic control device which is designed to output a switching signal when a removal or transfer request for a product segment is made.
  • a collecting device for the machine is advantageously provided.
  • at least part of the collecting device can be moved out of the machine through a removal sluice or extends through a removal sluice into the machine environment. After filling, this part of the collection device (e.g. collection container or conveyor belt) moves to the central removal lock. There must therefore only be one lock opening in the machine in order to remove removed product segments from the machine, so that the process climate inside the machine is not unnecessarily disturbed.

  • the Ven- til 45 is closed in the second circumferential position (e.g. at 3 o'clock) and then opened again before reaching the 9 o'clock position in order to be able to accept another product segment 82 .
  • the dispensing drum 52 has an ejection or dispensing position 50 at 6 o'clock, for example. If a specific product segment 82 is to be removed from the product flow, the control device 99 controls the corresponding valve 45 as a result of an ejection request by means of a switching signal when the product segment 82 to be removed has reached the dispensing position 50 in order to close the corresponding valve 45. Due to the lack of negative pressure at the delivery position 50, suction force is no longer exerted on the product segment 82 to be removed; this can fall down due to the force of gravity and is thus removed from the product flow. The valve 45 is opened again before the 9 o'clock position is reached in order to be able to receive another product segment 82 . In FIG.

  • the valve 47 in the compressed air line 46 is closed during normal production operation. If a product segment 82 is to be ejected from the delivery drum 52, the control device 90 controls the valve 47 in order to open it.
  • the compressed air then flowing out of the mouth of the compressed air line 46 breaks or neutralizes the negative pressure generated by the vacuum device 41 locally at the removal position 50, so that the suction force on the product segment 82 is eliminated and the product segment 82 can fall out of the product flow due to gravity.
  • FIGS. 4 and 5 can easily be modified in order to realize a branching or division of a product flow into two partial flows, i.e. a product switch in the machine 10, instead of ejecting a product segment 82. This is explained below with reference to FIG.

  • the valve 47 is opened by the control device 90 and the delivery position 50 is pressurized with compressed air in order to break the vacuum generated by the vacuum device 41 there (second switch setting). Since the delivery drum 52 no longer exerts a suction force on the product segment 82 located in the delivery position 50, this is sucked in and taken over by the vacuum sector 49 of the receiving drum 48.
  • product segment 82 is further promoted and can be delivered to one of the receiving drum 48 downstream, not shown te conveyor (second partial flow).
  • the negative pressure of the delivery drum 52 is broken or neutralized by means of compressed air in order to deliver a product segment 82 to the receiving drum 48 .
  • the vacuum of the dispensing drum 52 need not be reduced to zero to dispense a product segment 82 . It is generally sufficient for the transfer if the negative pressure of the receiving drum 48 exerts a stronger suction force on the product segment 82 than the negative pressure of the delivery drum 52.
  • FIG. 1 A further embodiment of a device for branching or dividing a product flow into two partial flows, i.e. a product diverter in the machine 10, is shown in FIG.
  • both the dispensing device 63 and the receiving device 24 are designed as in FIG.
  • the receiving drum 48 thus also has a vacuum device 66 supplied with vacuum from a vacuum reservoir 72 in order to hold and transport product segments 82 on the lateral surface 67 of the receiving drum 48 by means of vacuum.
  • the vacuum device 66 can be embodied in the form of one or more spatially fixed sectors.
  • the vacuum sector extends in the right half of the receiving drum 48 between 12 o'clock (possibly taken over by the delivery drum 52) and 6 o'clock (transfer to a downstream conveyor). Furthermore, a stationary compressed air line 68 with a switchable valve 69 arranged therein is provided, the compressed air line 68 opening out at or in the area of a receiving position 70 of the receiving drum 48 .
  • the control device 90 controls the valves 47, 69 in such a way that at any time one of the valves 47, 69 is open and the other valve 69, 47 is closed.
  • valve 69 When the valve 69 is open and the valve 47 is closed (first switch position), the compressed air emerging from the compressed air line 68 breaks the negative pressure generated by the vacuum device 66, the receiving drum 48 is deactivated and the drum held on the delivery drum 52 and passing through the delivery position 50 Product segments 82 are conveyed further on the delivery drum 52, here for example until 3 a.m. (first partial flow). If, on the other hand, the valve 47 is opened and the valve 69 is closed (second switch position), the compressed air emerging from the compressed air line 46 breaks the negative pressure generated by the negative pressure device 41 .
  • a device for branching or dividing a product stream can alternatively be produced starting from the delivery device 63 designed according to FIG. 4 by adding a receiving device 24 designed as in FIG. 6 or FIG.
  • a receiving device 24 designed as in FIG. 6 or FIG.
  • the central element of the dispensing device 63 in the form of a dispensing drum 52 was described.
  • Other designs are possible, for example in the form of a delivery belt conveyor. The same applies to the design of the receiving device 24.
