Description

LATCHES FOR FINISHING DEVICES

BACKGROUND

[0001] Printing systems, such as printers, copiers, etc. may generate text or images on to print media (e.g., paper, plastic, etc.). Printing systems generally include a stacking region for the collection of print media. The stacking region may be an output region where a user may receive the print media. In some examples, printing systems may include a finishing device where print media may be collected for a finishing process, such as stapling, three-hole punching, etc. The printing system may connect a media pathway to a finishing device to perform a finishing process on the print media.

[0008] Finishing devices and systems are described herein. Finishing devices are devices that may be coupled to printing devices for post processing. Printing devices, such as printers, copiers, etc., may generate text and/or images from a computing device on to print media, such as paper. A printing device may include a finishing device to perform post processing on print media utilized by the printing device.

[0009] A finishing device may include mechanisms to process print media following the printing process. For example, after the printing process is completed, print media may be transported to the finishing device. Processing print media may include transporting, stacking, aligning, collating, stapling, etc. the print media. The finishing device may utilize various mechanisms to process the print media. For example, the finishing device may utilize various mechanisms to control the print media throughout the post-print processing. The type of mechanism and/or sequence of utilizing the mechanisms may be influenced by the type of printing device being utilized.

[0010] in some examples, the finishing device may include a latch hook to receive a latch pin from a printing device and couple the printing device to the finishing device. In some examples, the finishing device may include a sensor flag to separate the finishing device from the printing device. For example, the sensor flag may extend towards the printing device causing the finishing device to separate from the printing device. In some examples, the finishing device may include a separation wedge to transition the sensor flag toward the printing device.

[0011] A finishing device may be connected to a printing device. In some examples, print media may be collected for a finishing process, such as stapling, three- hole punching, etc. As stated above, finishing is a term used for post processing of print media. For example, the finishing device can be coupled to a side of a printing device that includes an output of the printing device or an output of a print zone where printing fluid is applied to the print media, etc. In some examples, the finishing device may be adjacent to the printing device. For example, the finishing device may cover an output of the printing device or an opening of a print zone used to remove print media blocking the media pathway. As used herein, a media pathway refers to a path in printing device and/or finishing device in which print media is transported during the printing process.

[0012] For example, the latch hook of the finishing device may contact a latch pin of the printing device causing the finishing device and the printing device to be coupled together. However, the finishing device coupled to the printing device may prevent print media lodged in the media pathway from being removed. Accordingly, this disclosure describes systems and methods that allow a finishing device to be attached and detached from a printing device.

[0013] Figure 1 illustrates an example finishing device 100. The finishing device 100 may be implemented in a variety of printing devices, such as printers or copiers, for example. In some examples, the finishing device 100 may be coupled to a printing device. For example, the finishing device 100 may be an external finishing device that is attached to a printing device for post processing.

[0014] As used herein, external finishing device refers to a finishing device that conducts post processing of print media outside of the printing process in some examples, the printing device may have print media blocking the media pathway. As used herein, a blocked media pathway refers to print media blocking the media pathway, print media being jammed or lodged in the media pathway, a printing device being unable to remove or eject print media, or the printing device being unable to function properly until unwanted print media is removed from the media pathway.

[0015] When print media is blocking the media pathway the print media may be removed via an opening for the printing device to function properly (e.g., function according to manufacturer specifications, etc.). However, in some examples, the finishing device 100 when coupled to the printing device may block an opening that allows for removal of print media blocking the media pathway. Thus, the finishing device 100 may be detached from the printing device to allow for removal of print media blocking the media pathway.

[0016] in some examples, the finishing device 100 may include a latch hook 102- 1 , 102-2 to receive a latch pin (e.g., latch pin 514 as illustrated in Figure 5) from a printing device. For example, the latch hook 102-1 , 102-2 may contact and hold the latch pin in place causing the finishing device 100 and the printing device to couple together. In some examples, the latch hook 102-1 , 102-2 securely holds the latch pin in place when the finishing device 100 and the printing device are coupled together. In some examples, when a release mechanism is triggered the latch hook 102-1 , 102-2 may move out of contact with the latch pin removing the secure hold between the finishing device 100 and the printing device.

[0017] In some examples, the latch hook 102-1 , 102-2 may be comprised of a material capable of holding the weight or mass of the printing device. For example, the latch hook 102-1 , 102-2 may be comprised of different metals capable of holding the weight of the printing device, such as, steel, titanium, tungsten, inconel, nickel, cobalt, chromium, or a combination thereof. In some examples, the finishing device 100 may include a plurality of latch hooks 102-1 and 102-2 to attach and detach the finishing device 100 to the printing device. In some examples, the latch hook 102-1 , 102-2 may transition in a direction, along the axis, as denoted by the arrow 133. For example, the latch hook 102-1 may move towards the sensor flag 104-1 when the finishing device 100 is detaching from a printing device. Likewise, the latch hook 102-2 may move away from the sensor flag 104-2 when the finishing device 100 is detaching from a printing device. In some examples, the latch hook 102-1 may move away from the sensor flag 104-1 when the finishing device 100 is being coupled to a printing device. Likewise, the latch hook 102-2 may move towards the sensor flag 104-2 when the finishing device 100 is being coupled to a printing device.

[0018] in some examples, the finishing device 100 may include a separation wedge 106. In some examples, the latch hook 102-1 may cause the separation wedge 106 to transition in a direction, along the axis, as denoted by the arrow 133. For example, the separation wedge 106 may move towards the sensor flag 104-1 when the latch hook 102-1 is transitioning towards the separation wedge 106 and the finishing device 100 is detaching from the printing device in various examples, the separation wedge 106 may move away from the sensor flag 104-1 when the latch hook 102-1 is transitioning away from the sensor flag 104-1 and the finishing device 100 is being coupled to the printing device.

[0019] The separation wedge 106 is a wedge that may be adjacent to the latch hook 102-1. For example, the separation wedge 106 may comprise a body with two arms opposite one another, as illustrated in Figure 1. In some examples, the two arms may comprise a thin end furthest away from the body that transitions into a thick end closer to the body. In some examples, the separation wedge 106 may contact the sensor flag 104-1. For example, the thin end of the separation wedge 106 may contact the sensor flag 104-1. In various examples, the thick end of the separation wedge 106 may transition behind a sensor flag 104-1 to alter the position of the sensor flag 104-1.

In some examples, the separation wedge 106 may be comprised of a material to alter the position of the sensor flag 104-1. In some examples, the separation wedge 106 may be comprised of a polymer material such as plastic. For example, the separation wedge 106 may be comprised of different plastics capable of alter the position of the sensor flag 104-1 , such as, thermoplastic, polypropylene, or a combination thereof.

[0020] in some examples, the sensor flag 104-1 , 104-2 may move towards a printing device or away from the finishing device 100 when the thick end of the separation wedge 106 transitions behind the sensor flag 104-1. in some examples, the sensor flag 104-1 , 104-2 may move towards the finishing device 100 when the thick end of the separation wedge 106 is not behind the sensor flag 104-1. In some examples, sensor flag 104-1 , 104-2 may be adjacent to the latch hook 102-1 , 102-2. In some examples, the sensor flag 104-1 may be adjacent to the separation wedge 106. In some examples, the sensor flag 104-1 , 104-2 may be comprised of a polymer material such as plastic to separate the finishing device 100 from the printing device. For example, the sensor flag 104-1 , 104-2 may be comprised of different plastics, such as, thermoplastic, polypropylene, or a combination thereof.

[0021] in some examples, the sensor flag 104-1 , 104-2 may transition towards the sensor flag receptacle of the printing device in some examples, the finishing device 100 may include a plurality of sensor flags 104-1 and 104-2 to detach the finishing device 100 from the printing device. For exampie, the sensor flag 104-1 , 104-2 may cause the finishing device 100 to detach from the printing device by contacting the printing device. For exampie, when a release mechanism is triggered the latch hook 102-1 , 102-2 may move out of contact with the latch pin removing the secure hold between the finishing device 100 and the printing device. When the latch hook 102-1 ,

102-2 is no longer coupled to the latch pin the sensor flag 104-1 , 104-2 may push the finishing device 100 away from the printing device to cause the finishing device 100 to detach from the printing device.

[0022] Figure 2 illustrates an example finishing device 200. As illustrated in Figure 2, the finishing device 200 may include release mechanism 218 coupled to a latch hook 202. In some examples, the release mechanism 218 may be a release button to initiate a movement of a latch hook 202. For example, the release mechanism 218 may alter the position of the latch hook 202. In some examples, the release mechanism 218 may cause the latch hook 202 to transition in a direction, along the axis, as denoted by the arrow 233. For example, the release mechanism 218 may cause the latch hook 202 to move towards the sensor flag 204 when the finishing device 200 is detaching to a printing device in some examples, the latch hook 202 may move away from the sensor flag 204 when the finishing device 200 is being coupled to a printing device. In some examples, the release mechanism 218 may trigger the release of the finishing device 200 from the printing device by initiating the separation of the latch hook 202 and the latch pin (e.g., latch pin 514 as illustrated in Figure 5). In some examples, the release mechanism 218 may be located on a side of the finishing device 200 that is perpendicular to the latch hook 202.

[0023] in some examples, the finishing device 200 may include a latch hook 202 to receive a latch pin from a printing device. In various examples, the latch hook 202 may contact and hold the latch pin in place, coupling the finishing device 200 and the printing device. For example, the latch hook 202 may securely hold the latch pin in place when the finishing device 200 and the printing device are coupled together. In some examples, when a release mechanism 218 is triggered the latch hook 202 may move out of contact with the latch pin removing the secure hold between the finishing device 200 and the printing device. In some examples, the latch hook 202 may be comprised of steel in some examples, the finishing device 200 may include a plurality of latch hooks 202 to contact with a plurality of latch pins.

[0024] in some examples, the finishing device 200 may include a separation wedge 206. In some examples, the separation wedge 206 may be adjacent to the latch hook 202. In some examples, the latch hook 202 may cause the separation wedge 206 to transition towards the sensor flag 204 (i.e., along the axis denoted by the arrow 233). In some examples, the latch hook 202 may cause the separation wedge 206 to move towards the sensor flag 204 when a release mechanism 218 is actuated. For example, when a release mechanism 218 is triggered the latch hook 202 may transition towards the sensor flag 204 causing the separation wedge to transition towards the sensor flag 204. In some examples, the finishing device 200 may include a plurality of separation wedges 206 to transition towards the sensor flag 204. In various examples, the separation wedge 206 may move away from the sensor flag 204 when the latch hook 202 is transitioning away from the sensor flag 204.

[0025] in some examples, the separation wedge 206 is a wedge that may be adjacent to the sensor flag 204. In various examples, the separation wedge 206 may be in contact with the sensor flag 204. For example, the separation wedge 206 may comprise of a body with two arms opposite one another. In some examples, the two arms of the separation wedge 206 may have a thin end furthest away from the body that may transition into a thick end closer to the body. In various examples, the thin end of the separation wedge 206 contacts the sensor flag 204. In various examples, the thick end of the separation wedge 206 may transition behind a sensor flag 204 and contact the sensor flag 204 in order to alter the position of the sensor flag 204

[0026] For example, the separation wedge 206 may cause the sensor flag 204 to transition away from the finishing device 200 when the thick end of the separation wedge 206 transitions behind the sensor flag 204. In some examples, the sensor flag 204 may cause the finishing device 200 to detach from a printing device when a release mechanism 218 is triggered. For example, when a release mechanism 218 is triggered the separation wedge 206 may move behind the sensor flag 204 causing the sensor flag 204 to push the finishing device 200 away from the printing device.

[0027] in some examples, the sensor flag 204 may transition towards the sensor flag receptacle of the printing device. For exampie, the sensor flag may transition between a start position and an end position. As used herein, a start position of the sensor flag refers to the position the sensor flag is in when the release mechanism has not been actuated. As used herein, an end position of the sensor flag refers to the position the sensor flag is in when the release mechanism has been actuated. In some examples, the finishing device 200 may include a plurality of sensor flag 204 to detach the finishing device 200 from the printing device. For example, the sensor flag 204 may cause the finishing device 200 to detach from the printing device by contacting the printing device.

[0028] Figure 3 illustrates an example system including a finishing device. In some examples, the system 330 may include a finishing device 300 for post processing of print media in some examples, the finishing device 300 may include a release mechanism (e.g., release mechanism 218 as illustrated in Figure 2) to alter the position of the latch hook (e.g., latch hook 102-1 as illustrated in Figure 1). In some examples, the release mechanism may be a release button to initiate a movement of latch hook in some examples, the release mechanism may cause a latch hook to move towards the sensor flag (e.g., sensor flag 104-1 as illustrated in Figure 1). in some examples, the release mechanism may trigger the release of the finishing device 300 from the printing device 322 by initiating the separation of the latch hook and the latch pin (e.g., latch pin 514 as illustrated in Figure 5). In some examples, the release mechanism may be located on a side of the finishing device 300 that is perpendicular to the latch hook.

[0029] in some examples, the finishing device 300 may include a latch hook to receive a latch pin from a printing device 322. In various examples, the latch hook may contact and hold the latch pin in place, coupling the finishing device 300 and the printing device 322. For example, the latch hook may securely hold the latch pin in place when the finishing device 300 and the printing device 322 are coupled in some examples, when a release mechanism is triggered the latch hook may move out of contact with the latch pin removing the secure hold between the finishing device 300 and the printing device 322.

[0030] in some examples, the finishing device 300 may include a separation wedge (e.g., separation wedge 206 as illustrated in Figure 2). In some examples, the latch hook may cause the separation wedge to move towards the sensor flag when a release mechanism is actuated. For example, when a release mechanism is triggered the latch hook may transition towards the sensor flag causing the separation wedge to transition towards the sensor flag.

[0031] in some examples, the sensor flag may transition towards the sensor flag receptacle of the printing device 322. In some examples, the finishing device 300 may include a plurality of sensor fiags to detach the finishing device 300 from the printing device 322. For exampie, the sensor flag may cause the finishing device 300 to detach from the printing device 322 by contacting the printing device 322. For example, when a release mechanism is triggered the latch hook may move out of contact with the latch pin removing the secure hold between the finishing device 300 and the printing device 322. When the latch hook is no longer coupled to the latch pin the sensor flag may transition towards the printing device 322 and push the finishing device 300 away from the printing device 322 cause the finishing device 300 to detach from the printing device 322.

[0032] In some examples, the printing device 322 may include a latch pin to contact a latch hook of a finishing device 300. For example, when the finishing device is coupled to the printing device, the latch pin may contact the channel of the latch hook.

[0033] in some examples, the printing device 322 may include a sensor flag receptacle (e.g., sensor flag receptacle 516 as illustrated in Figure 5) to receive a sensor flag of the finishing device 300. In some examples, the sensor flag receptacle may house the sensor flag when the printing device 322 is attached to the finishing device 300. For example, when the printing device is coupled to the finishing device the sensor flag may sit inside of the sensor flag receptacle in various examples, the sensor flag may contact the back of the sensor flag receptacle when the finishing device is being detached from the printing device.

[0034] in some examples, the printing device 322 may include an alignment pin (e.g., alignment pin 512 as illustrated in Figure 5) to receive an alignment receptacle (e.g., alignment receptacle 610 as illustrated In Figure 6) of the finishing device 300. In some examples, the alignment pin may be used to align the printing device 322 with the finishing device 300 when the finishing device 300 and the printing device 322 are coupled together.

[0035] Figure 4 illustrates an example latching system 440 for a finishing device in some examples, the latching system 440 may couple a printing device to a finishing device. In some examples, the latching system 440 may include a latch hook 402-1 , 402-2 to receive a latch pin from a printing device. In some examples, the latch hook 402-1 may transition towards a sensor flag 404-1 (i.e., in a direction, along the axis, as denoted by the arrow 433). In some examples, the latch hook 402-1 , 402-2 contains a channel 424 to receive a latch pin from the printing device. In various examples, the channel 424 may contact and hold the latch pin in place coupling the finishing device and the printing device. For example, the channel 424 may securely hold the latch pin in place when the finishing device and the printing device are coupled.

[0036] In some examples, the channel 424 is defined by a first surface 426 and a second surface 428. In various examples, the first surface 426 is longer than the second surface 428. In some examples, the first surface 426 stops the latch pin from moving outside of the channel 424 until a release mechanism is actuated. In some examples, the finishing device may include a plurality of channels 424 to receive a latch pin.

[0037] in some examples, the latching system 440 may include a separation wedge 406. In some examples, the latch hook 402-1 may cause the separation wedge 406 to move towards the sensor flag 404-1 when a release mechanism is actuated. For example, the separation wedge 406 may cause the sensor flag 404-1 , 404-2 to transition away from the finishing device towards the printing device to detach the finishing device from the printing device.

[0038] in some examples, the latching system 440 may include a sensor flag 404-1 , 404-2. In some examples, the sensor flag 404-1 , 404-2 may transition towards the sensor flag receptacle of the printing device in some examples, the sensor flag 404-1 , 404-2 may be housed in a sensor flag receptacle when the finishing device is coupled to the printing device. In some examples, the sensor flag 404-1 , 404-2 may to transition toward the printing device when a release mechanism is actuated.

[0039] in some examples, the sensor flag 404-1 , 404-2 may be in alignment with a sensor 408. In some examples, the sensor flag 404-1 , 404-2 may move out of alignment with the sensor 408 when the release mechanism is actuated. For example, the sensor flag 404-1 , 404-2 may move towards a printing device (i.e., in a direction, along the axis, as denoted by arrow 444). in various examples, the sensor 408 may send a signal to the finishing device when the sensor flag 404-1 , 404-2 moves out of alignment with the sensor 408. As used herein, sensor, refers to an electronic computing device to detect when the sensor flag is not aligned with the sensor, an electronic computing device to send a signal to a finishing device when the sensor is not aligned with the sensor flag, and/or an electronic computing device to send a signal to a finishing device notifying the finishing device that it is detaching from the printing device.

[0040] Figure 5 illustrates an example printing device 522. The printing device 522 may be implemented in a variety of imaging systems, such as inkjet printers or copiers, for example. In some examples, the printing device 522 may include a latch pin 514 to contact a latch hook (e.g., latch hook 202 as illustrated in Figure 2) of a finishing device. In some examples, the latch pin 514 may rotate as it contacts the latch hook of the finishing device. For example, when the finishing device is coupled to the printing device 522, the latch pin 514 may rotate as it contacts the channel of the latch hook. Likewise, when the finishing device is detaching from the printing device 522 the latch pin 514 may rotate as the channel of the latch hook moves out of contact with the latch pin 514. in some examples, the printing device 522 may include a plurality of latch pins 514 to contact a latch hook in some examples, the latch pin 514 may be comprised of different metals capable of holding the printing device 522 and the finishing device together in various examples, the latch pin 514 may be comprised of metal. For example, the latch pin 514 may be comprised of different metals capable of holding the printing device 522 and the finishing device together, such as, steel, titanium, tungsten, inconel, nickel, cobalt, chromium, or a combination thereof.

[0041] In some examples, the printing device 522 may include a sensor flag receptacle 516 to receive a sensor flag (e.g., sensor flag 204 as illustrated in Figure 2) of the finishing device in some examples, the sensor flag receptacle 516 may house the sensor flag when the printing device 522 is attached to the finishing device. For example, when the printing device 522 is coupled to the finishing device the sensor flag may sit inside of the sensor flag receptacle 516. In various examples, the sensor flag may contact the back of the sensor flag receptacle 516 when the finishing device is being detached from the printing device 522.

[0042] in some examples, the printing device 522 may include an alignment pin 512 to receive an alignment receptacle (e.g., alignment receptacle 610 as illustrated in Figure 8) of the finishing device. In some examples, the alignment pin 512 may be used to align the printing device 522 with the finishing device when coupled together. For example, the alignment pin may ensure that the printing device 522 and the finishing device are coupled so the finishing device is able to function while attached to the printing device. In some examples, the alignment pin 512 is adjacent to the sensor flag receptacle 516. in some example, the alignment pin may be positioned between the plurality of sensor flag receptacles 516.

[0043] Figure 6 illustrates an example system 630 for a finishing device. As illustrated in Figure 6, the system 630 may include a finishing device 600 and a printing device 622. in some example, the finishing device 600 may be used to process print media. In some examples, the release mechanism 618 may alter the position of the latch hook 602. For example, the finishing device 600 may include a release

mechanism 618 to transition the latch hook 602 from a first position to a second position. As used herein, a first position of the latch hook refers to the position the latch hook is in when the release mechanism has not been actuated. As used herein, a second position of the latch hook refers to the position the latch hook is in when the release mechanism has been actuated in some examples, the release mechanism 618 may trigger the release of the finishing device 600 from the printing device 622 by initiating the separation of the latch hook 602 and the latch pin 614. In some examples, the release mechanism 618 may be located on the side of a finishing device 600 that is perpendicular to the side the latch hook 602 is on.

[0044] in some examples, the finishing device 600 may include a latch hook 802 to receive a latch pin 814 from a printing device 622. For example, the latch hook 602 may contact and hold the latch pin 814 in place causing the finishing device 600 and the printing device 622 to couple together in some examples, the latch hook 602 securely holds the latch pin 614 in place when the finishing device 600 and the printing device 622 are coupled. In some examples, when the release mechanism 618 is triggered the latch hook 602 may move out of contact with the latch pin 814, removing the secure hold between the finishing device 600 and the printing device 622.

[0045] in some examples, the system 630 may include a separation wedge 606 to transition behind the sensor flag 604. For example, the latch hook 602 may cause the separation wedge 606 to move towards the sensor flag 604 when a release mechanism 618 is actuated, by moving the separation wedge 606 as the latch hook 602 moves towards the sensor flag 604. In some examples, the separation wedge 606 may cause the sensor flag 604 to transition away from the finishing device 600 towards the printing device 622 to detach the finishing device 600 from the printing device 622. In some examples, the separation wedge 606 may cause the sensor flag 604 to transition away from the finishing device 600.

[0046] In some examples, the sensor flag 604 may cause the finishing device 600 to detach from a printing device 622. In some examples, the sensor flag 604 may transition toward the printing device 622 when a release mechanism 618 is actuated. In some examples, the sensor flag 604 may transition towards the sensor flag receptacle 616 of the printing device 622. In some examples, the sensor flag 604 may be housed in a sensor flag receptacle 616 when the finishing device 600 is coupled to the printing device 622.

[0047] in some examples, the printing device 622 may include a latch pin 614 to contact a latch hook 602 of a finishing device 600. in some examples, the latch pin 614 may rotate as it contacts the latch hook 602 of the finishing device 600
