Description

State of the art

[0001] A device for moving load carriers is known from EP 3 552 998 A2. Disclosure of the invention

[0002] A transport device for transporting and transferring a transport item is proposed, wherein the transport device comprises a conveyor unit for conveying the transport item, a transport item securing device for fixing the transport item in a transfer position and a transfer device for receiving the transport item from the conveyor unit, wherein the transport item securing device and the transfer device interact when the transport item securing device and the transfer device come into contact in such a way that the fixing of the transport item is released for transferring the transport item from the conveyor unit.

[0003] Advantageously, the transported goods securing device and the transfer device each comprise a spring-returned first hook and a spring-returned second hook. The first hook and the second hook are each rotatably mounted on an axis and arranged in a first position by means of a spring-return moment. Furthermore, the first hook and the second hook each have a fixing surface for fixing the transported goods, with the first hook having a nose and the second hook having a receiving area.When the transported goods securing device and the transfer point meet, the nose of the first hook contacts the receiving area of ​​the second hook in such a way that the first hook and the second hook can be rotated into a second position against the spring return moment, wherein the respective fixing surface is also rotated in such a way that the fixing of the transported goods in the second position is released and the transported goods can be or are transferred from the conveyor unit to the transfer device.

[0004] The advantage of the proposed transport device is that the transported goods can be transported particularly safely and / or reliably and transferred from a conveyor unit to a transfer device. Advantageously, the present transport device enables a mechanical transport lock, which can reduce or prevent the likelihood of a transported good falling. Advantageously, this can enable fall protection for the element to be transported, for example, a workpiece carrier, boxes, or other items. This enables a safe and / or reliable transfer and / or transport of the transported goods, thereby preventing damage or property damage, for example, to the transported goods and / or the transport device.The mechanical design of the cargo securing system makes it possible to circumvent errors, such as those in electrical controls or programming. This enables reliable securing of the cargo without the risk of accidentally releasing the cargo, which could result in a fall or collision, for example. The implementation of a mechanical cargo securing system can, in particular, save costs and / or effort.

[0005] The transport device's pairs of hooks ensure that the transported goods or load do not fall, for example, if the transport device stops abruptly. Advantageously, the transported goods can be secured in such a way that the likelihood of them slipping or turning sideways is reduced or prevented. Advantageously, the securing mechanism by the pairs of hooks is only released when the transport device is positioned sufficiently precisely relative to the transfer device.

[0006] In an exemplary embodiment, to secure the transported goods, the goods can be pressed against the fixing surface of the first hook and the second hook, whereby a first torque about the axis generated thereby is smaller than the spring return torque. This allows the transported goods to be secured, particularly safely and / or reliably, until a corresponding transfer device is docked. This can prevent a fall and thus damage to the transported goods.

[0007] Advantageously, a second torque about the axis generated when the nose of the first hook contacts the receiving area of ​​the second hook can be greater than the spring return torque. This allows the transported goods to be released, particularly when the transported goods securing device docks onto a transfer device, which can then be passed on to the transfer device. Advantageously, it can be ensured that the transported goods are only unlocked and thus released when a corresponding transfer device is present or docked.

[0008] In a further development, the axle can be positioned closer to a support surface for the transported goods on the conveyor unit than the nose and / or the receiving area. This enables reliable securing and thus retention of the transported goods, provided no transfer device is docked. Advantageously, this allows a low moment to be exerted on the securing surface and thus on the hook by the load or the transported goods. Due to an extended lever of the nose and / or the receiving area, less force can be required to trigger the transport locking mechanism.

[0009] Furthermore, the first hook and the second hook can be rotated back to the first position by means of the spring return torque, preferably after the transported goods securing device and the transfer device have been removed from each other. This allows the transport device to be prepared for a new item to be transported, which can be held and thus secured again by means of the hooks.

[0010] In an advantageous embodiment, the transported goods securing device and the transfer device can each have a stop, such that the first hook and the second hook can be rotated from the first position in a first direction counter to the spring return torque. In a further development, after the transported goods securing device has been removed from the transfer device, the first hook and the second hook can be rotated back into the first position up to the stop by means of the spring return torque. This can ensure that the hook is not rotated further beyond the stop. This can advantageously enable a secure and / or reliable positioning of the hooks in the first position and thus in a spring-biased first position.

[0011] In an exemplary embodiment, the transported goods securing device, the transfer device, the respective first hooks and / or the respective second hooks can have a spring enclosure. Advantageously, this allows the spring to be held in one position and not jump off sideways under load. This can ensure the functionality of the spring. Advantageously, a preload force of the spring can be influenced via a depth of the spring enclosure. Furthermore, the spring return torque can be influenced via a distance between the axis and the spring enclosure. This can influence a safe and reliable adjustment of the spring and thus the spring return torque. This can in particular enable a secure fixation of the hooks in the first position, whereby a reliable fixation of the transported goods can be ensured.

[0012] In a further development, the axis can be arranged perpendicular to a conveying direction of the conveyor unit. This can enable secure and / or reliable holding of the transported goods and / or transfer of the transported goods to a transfer device.

[0013] Advantageously, the transfer device can be designed as an additional transported goods securing device. This allows the transported goods to be transferred, in particular, safely and / or reliably from one conveyor unit to another conveyor unit via the transported goods securing device. This enables safe and / or reliable conveyance of the transported goods.

[0014] In an advantageous embodiment, when the transported goods securing device and the transfer device meet, the nose of the first hook of the transported goods securing device can be contacted with the receiving area of ​​the second hook of the transfer device in such a way that the first hook of the transported goods securing device and the second hook of the transfer device can be rotated into a second position counter to the spring return moment, wherein the respective fixing surface is also rotated in such a way that the fixing of the transported goods in the second position is released and the transported goods can be transferred from the conveyor unit to the transfer device.Alternatively or additionally, when the transported goods securing device and the transfer point come into contact, the nose of the first hook of the transfer device can contact the receiving area of ​​the second hook of the transported goods securing device in such a way that the first hook of the transfer device and the second hook of the transported goods securing device can be rotated into a second position against the spring return torque, wherein the respective fixing surface is also rotated in such a way that the fixing of the transported goods in the second position is released and the transported goods can be transferred from the conveyor unit to the transfer device. This can enable reliable securing and / or reliable transport of the transported goods. In particular, this can prevent property damage.

[0015] Furthermore, a method for transporting and transferring a transport item by means of a transport device according to one of the preceding claims is proposed, comprising the steps, Collision of the transport goods securing device and the transfer device, contact of the receiving area of ​​the second hook with the nose of the first hook, Turning the first hook and the second hook against the spring return torque into the second position, whereby the respective fixing surface is also turned, Release the fixation of the transported goods by turning in the second position, transfer the transported goods from the conveyor unit to the transfer device.

Advantageously, the first support 32 can be arranged on the conveyor unit 22.In a further development, the first carrier 32 can be arranged on the conveyor unit 22 via a further, second carrier 34. The second carrier 34 can advantageously be part of the conveyor unit 22. Advantageously, the axis 30 can be arranged perpendicular to a conveying direction, in particular to the conveying direction of the conveyor unit 22. In other words, the conveyor unit 22 transports a transported item in one direction, with the axis 30 being arranged in particular perpendicular to the direction. Advantageously, the first hook 26 and the second hook 28 are arranged parallel to one another and can rotate in the same direction.

[0021] The first hook 26 and the second hook 28 each have a securing surface 36, 38 for securing the transported goods. In particular, the first hook 26 has a first securing surface 36, and the second hook 28 has a second securing surface 38. Advantageously, due to the double hook or the pair of hooks, in particular the arrangement of the first hook 26 and the second hook 28, a wider approach surface, thus a wider securing surface 36, 38, can be formed. This can, in particular, prevent the transported goods from twisting or falling sideways.

[0022] Furthermore, the first hook 26 has a nose 40 and the second hook 28 has a receiving area 42. When the transported goods securing device 24 and the transfer device come into contact, the nose 40 of the first hook 26, in particular of the transported goods securing device 24 or the transfer device, contacts the receiving area 42 of the second hook 28, in particular of the respective other device, in such a way that the first hook 26 and the second hook 28 can be rotated into a second position against the spring return moment, wherein the respective fixing surface 36, 38 is also rotated in such a way that the fixing of the transported goods in the second position is released and the transported goods can be or are transferred from the conveyor unit 22 to the transfer device.

[0023] Fig. Figure 2 shows a schematic representation of a part of a transport device 20 for transporting and transferring a transport item 44 according to an embodiment of the present invention. The transport device 20 according to Fig. 2 can be carried out according to the transport device 20 according to Fig. 1. In this advantageous embodiment, the transport device 20 is shown in section from one side and secures a transport item 44, with the first hook 26 visible. Preferably, in this advantageous embodiment, the transport item is shown in the transfer position, thus fixed by the transport item securing device 24.

[0024] The transport item is transported in particular by the conveyor unit 22 in the direction of the hooks, here the first hook 26, and contacts the fixing surface 36 of the first hook 26. In other words, the transport item 44 is docked to the transport lock 24 and thus in particular to the hook pair 26 and thus to the first hook 26. To fix the transport item 44, the transport item 44 is pressed against the fixing surface 36 of the first hook 26 and the second hook, wherein a first torque 46 generated thereby about the axis 30 is smaller than the spring restoring torque 48. The first torque 46 is shown according to the arrow 46 and the spring restoring torque 48 or spring moment 48 is shown according to the arrow 48. In other words, the transport item 44 is fixed in the current position by the hook pair 26 in that the transport item 44 touches or contacts the fixing surface 36.is pressed against it, whereby a first torque 46 is generated about the axis 30, which is in particular smaller than the spring return torque 48. In other words, the first torque 46, which is generated by the impacted transport material 44, is smaller than the spring torque 48.

[0025] Advantageously, the axis 30 is arranged closer to a support surface 50 for the transported material 44 on the conveyor unit 22 than the nose 40 and / or the receiving area of ​​the respective hook.

[0026] Fig. 3 shows a schematic representation of a part of a transport device 20 for transporting and transferring a transport item 44 according to an embodiment of the present invention. The transport device 20 according to Fig. 3 can be according to the transport device 20 according to Fig. 1 and / or Fig. 2. In this advantageous embodiment, the transport device 20 is shown in section from one side, with the second hook 28 visible.

[0027] Advantageously, the transported goods securing device 24, here in particular the first carrier 32, the transfer device, in particular a carrier of the transfer device, the respective first hooks and / or the respective second hooks 28 have a spring surround 52. Advantageously, the spring surround 52 is a cavity 52 or depression 52 in which the spring, which is not shown here, is arranged and thus fixed. In other words, the spring surround 52 holds the spring in position so that it does not jump off sideways in the event of a load. Advantageously, a preload force of the spring can be influenced or influenced via a depth of the spring surround 52. In other words, the preload force in particular can be varied via the depth of the surround 52. The deeper the spring surround 52, the lower the preload force of the spring.Furthermore, the spring restoring torque is or can be influenced via a distance between the axis 30 and the spring mount 52. In other words, the spring torque can be influenced via the distance between the rotational axis 30 and the mount 52. The greater the distance between the axis 30 and the spring mount 52, the higher the spring restoring torque. Advantageously, the transport lock can be adjusted to different transported goods using the various adjustment options for the spring or the spring restoring torque. Depending on the position of the spring, spring hardness, and spring preload force, a resistance can preferably be adjusted. The height of the spring can be adjusted using the spring mount 52 or elongated holes.

[0028] Furthermore, the transported goods securing device 20 and in particular also the transfer device each have a stop 54 such that the first hook and the second hook 28 can be rotated from the first position in a first direction counter to the spring return moment. In other words, the first hook and the second hook 28 can be rotated from the first position in a direction counter to the spring return moment. By means of the stop 54, the spring can be held in a preloaded state, whereby the first hook and the second hook 28 are each designed as a spring-preloaded hook. Advantageously, after the transported goods securing device 24 has been removed from the transfer device, the first hook and the second hook 28 can be rotated back into the first position up to the stop 54 by means of the spring return moment.

[0029] Fig. 4 shows a schematic representation of a part of a transport device 20 for transporting and transferring a transport item 44 according to an embodiment of the present invention. The transport device 20 according to Fig. 4 can be according to the transport device 20 according to Fig. 1, Fig. 2 and / or Fig. 3. By means of the transport device 20, a method according to Fig. 5. In this advantageous embodiment, the transport device 20 is shown in section from one side, illustrating a transfer of the transported goods 44 from the transported goods securing device 24 to the transfer device 56. The transfer device 56 can be designed, in particular, as a further transported goods securing device, for example, of a further transport device.

[0030] When the transported goods securing device 24 comes into contact with the transfer device 56, the nose 40 of the first hook 26 contacts the receiving area 42 of the second hook 28, in particular of the respective other device, in particular the transported goods securing device 24 or the transfer device 56. In other words, the transport device 24 is moved towards the transfer device 56 or vice versa in such a way that the nose 40 is moved towards the receiving area 42 until they touch or make contact. A certain approach accuracy can be tolerated here, for example plus / minus 3 to 5 mm positioning accuracy. Advantageously, the nose 40 of the first hook 26 contacts the receiving area 42 of the second hook 28 in such a way that a force 58 is created between the first hook 26 and the second hook 28. As a result, the first hook 26 and the second hook 28 are rotated into a second position counter to the spring return torque.Advantageously, the first hook 26 is rotated according to the first arrow 60 and the second hook 28 according to the second arrow 62. This creates a further, second torque 60, 62 about the axis 30. In other words, when the nose 40 of the first hook 26 contacts the receiving area 42 of the second hook 28, a further torque 60, 62 is generated in the respective hook, thus a further, second torque 60 of the first hook 26 and a further, second torque 62 of the second hook 28. The further, second torque 60, 62 generated thereby about the axis 30 is in particular greater than the spring restoring torque, whereby the hooks are rotated about the axis 30.

[0031] Advantageously, the respective fixing surface 36, 38 of the respective hooks 26, 28 is also rotated. In other words, the first fixing surface 36 is rotated with the first hook 26 and the second fixing surface 38 is rotated with the second hook 28. Advantageously, the respective fixing surface 36, 38 is rotated in such a way that the fixation of the transported item 44 in the second position is released and the transported item 44 can be or is transferred from the conveyor unit 22 to the transfer device 56. In other words, the fixing surface 36 disappears as a result of the rotation of the hooks 26, 28, in particular below the surface 50 of the conveyor unit 22 on which the transported item 44 is arranged. As a result, the transported item 44 can be transferred from the conveyor unit 22 to the transfer device 56 by means of a drive of the conveyor unit 22 and can thus be transported further, in particular in the direction 64 along the arrow 64.

[0032] When the transported item 44 has been transferred to the transfer device 56 and the transported item securing device 24 and the conveyor unit 22 move away from the transfer device 56, the first hook 26 and the second hook 28 are rotated back to the first position by means of the spring return torque. Advantageously, the first hook 26 and the second hook 28 are rotated back to the first position up to the stop 54 by means of the spring return torque.

[0033] In an advantageous embodiment, when the transported goods securing device 24 and the transfer device 56 come into contact, the nose 40 of the first hook 26 of the transported goods securing device 24 can contact the receiving area 42 of the second hook 28 of the transfer device 56 in such a way that the first hook 26 of the transported goods securing device 24 and the second hook 28 of the transfer device 56 can be rotated into a second position against the spring return moment, wherein the respective fixing surface 36, 38 is also rotated in such a way that the fixing of the transported goods 44 in the second position is released and the transported goods 44 can be transferred from the conveyor unit 22 to the transfer device 56.Advantageously, when the transported goods securing device 24 and the transfer device 56 come into contact, alternatively or additionally, although not shown in this advantageous embodiment, the nose 40 of the first hook 26 of the transfer device 56 contacts the receiving area 42 of the second hook 28 of the transported goods securing device 24 in such a way that the first hook of the transfer device 56 and the second hook 28 of the transported goods securing device 24 can be rotated into a second position counter to the spring return moment, wherein the respective fixing surface 36, 38 is also rotated in such a way that the fixing of the transported goods 44 in the second position is released and the transported goods 44 can be transferred from the conveyor unit 22 to the transfer device 56.

[0034] In other words, when the conveyor unit 22 and the transported goods securing device 24 move to the correct position of the transfer device 56, the opposing hooks 26, 28 can be pressed down, allowing the load or the transported goods 44 to be transferred. Due to its geometry, the second hook 28 can only be triggered by its matching counterpart, in particular the first hook 26, and not, for example, by hitting a support or the like. Each hook pair 26, 28 has one hook with a nose 40 and one without a nose, in particular with a receiving area 42.

[0035] Advantageously, the rotation axis 30 is positioned as high as possible, particularly close to the support surface 50 of the conveyor unit 22 for the transported goods 44, since only a small moment is thus generated by the load 44. However, due to the extended lever, particularly by the pair of hooks 26, 28, downwards, no great force is required to trigger the mechanism.

[0036] Due to the symmetrical component arrangement, the safety device can also be triggered from one transport device to another. Furthermore, the dual arrangement ensures that the basic function of the transport lock is maintained even if a spring breaks. The likelihood of accidental triggering is also reduced, as both hooks act and can be triggered separately.

[0037] Fig. Figure 5 shows a schematic representation of a method 70 for transporting and transferring a transport item by means of a transport device according to an embodiment of the present invention. The transport device can be designed according to the transport device according to Fig. 1, Fig. 2, Fig. 3 and / or Fig. 4 be trained.

[0038] In a first step 72 of the method 70, the transported goods securing device and the transfer point meet. For example, they can be moved towards one another. Alternatively, one of the components can also be moved towards the other. In one embodiment, the transported goods securing device is moved towards the transfer device. Alternatively, the transfer device can also be moved towards the transported goods securing device. In a second step 74 of the method 70, the receiving area of ​​the second hook is contacted by means of or with the nose of the first hook, the respective other device, in particular the transported goods securing device and / or transfer device. As a result, in a third step 76 of the method 70, the first hook and the second hook are rotated counter to the spring return torque into the second position, wherein the respective fixing surface is also rotated.As a result, in a fourth step 78 of the method 70, the fixation of the transported item is released by rotating it into the second position. In a fifth step 80 of the method 70, the transported item is transferred from the conveyor unit to the transfer device. QUOTES CONTAINED IN THE DESCRIPTION
