[0055] Please refer to Figures 1 to 3 The embodiment of the present application provides a tray changing device 100, comprising a first conveying mechanism 110 and a second conveying mechanism 120. The first conveying mechanism 110 and the second conveying mechanism 120 are arranged along a first direction F1, and the second conveying mechanism 120 is arranged downstream of the first conveying mechanism 110 along the first direction F1.

[0056] The first conveying mechanism 110 is a mechanism for separating the material W from the initial tray T0 and conveying the material W along the first direction F1. The material W may be a plate. Specifically, the first conveying mechanism 110 includes a plurality of first conveying units 111 arranged at intervals. A first accommodating space Q1 for accommodating the initial tray T0 is defined between the plurality of first conveying units 111. Figure 4 For example, Figure 4 FIG. 1 is a schematic diagram showing a first conveying unit 111 in use provided in some embodiments of the present application, illustrating a situation where an initial tray T0 is accommodated in the first accommodation space Q1. Figure 3 and Figure 4 , multiple first conveying units 111 are used to jointly carry the material W installed on the initial tray T0, and convey the material W along the first direction F1. That is, the multiple first conveying units 111 are independent of each other, and the intervals between the first conveying units 111 constitute the first accommodating space Q1. The multiple first conveying units 111 can be synchronously driven by the same driving member, or can be synchronously driven by multiple driving members one by one, and no specific restrictions are made here. The driving member can be connected to the corresponding first conveying unit 111 by means of relevant transmission components, and no specific restrictions are made here. For example, the relevant transmission components can be a gear set and a shaft assembly, etc. For another example, the relevant transmission components can be belt transmission related components, etc. The relevant transmission components can be set according to specific usage requirements, and no specific restrictions are made here.

[0057] The first conveying unit 111 is a unit with a conveying function. Specifically, the first conveying unit 111 may include at least one first conveying roller 111a, and the extension direction of the rotation axis of the first conveying roller 111a is perpendicular to the first direction F1. In this way, when the first conveying roller 111a is driven to rotate by a related driving member, the material W placed on the first conveying roller 111a can move along the first direction F1 under the rotation of the first conveying roller 111a, thereby realizing the movement of the material W along the first direction F1. Figure 3 As an example, the first conveying unit 111 includes two first conveying rollers 111a. Of course, the number of first conveying rollers 111a provided in each first conveying unit 111 can be the same or different, and there is no specific limitation here.

[0058] When the pallet fork places the initial pallet T0 loaded with the material W on the first conveying mechanism 110, the initial pallet T0 can fall under the action of gravity and be accommodated in the first accommodation space Q1, and the material W is carried on the first conveying unit 111. In this way, by setting up the first conveying mechanism 110, the material W can be separated from the initial pallet T0, and the removal operation can be completed.

[0059] Combined with reference Figure 5 , Figure 5 The schematic diagram of the three-dimensional structure of the second conveying mechanism 120 provided in some embodiments of the present application is shown. The second conveying mechanism 120 is a mechanism for receiving the material W conveyed by the first conveying mechanism 110 along the first direction F1 and installing the material W on the target tray T1. Figure 5Schematically shows a situation where the target tray T1 is installed on the second conveying mechanism 120. Specifically, the second conveying mechanism 120 includes a plurality of second conveying units 121 arranged at intervals, and a second accommodating space Q2 for accommodating the target tray T1 is defined between the plurality of second conveying units 121. The second conveying unit 121 is used to convey the material W along the first direction F1 and to perform lifting and lowering movements along the second direction F2, so as to carry the material W conveyed by the first conveying mechanism 110 and transfer the material W to the target tray T1. Among them, the first direction F1 and the second direction F2 are perpendicular to each other. In the embodiment of the present application, the second direction F2 is a vertical direction, and the first direction F1 is a horizontal direction. The plurality of second conveying units 121 are independent of each other, and the intervals between the second conveying units 121 constitute the second accommodating space Q2. The plurality of second conveying units 121 can be synchronously driven by the same driving member, or can be synchronously driven by a plurality of driving members one by one, which is not specifically limited here. The driving member can be connected to the corresponding second conveying unit 121 by means of relevant transmission components, which is not specifically limited here. The relevant transmission components can be understood by referring to the embodiments of some relevant transmission components illustrated above, which will not be described in detail here. It can be understood that the component that drives the second conveying unit 121 to convey the material W along the first direction F1 and the component that drives the second conveying unit 121 to move up and down along the second direction F2 are different driving components.

[0060] The second conveying unit 121 is a unit with a conveying function. Specifically, the second conveying unit 121 may include at least one second conveying roller 121a, and the extension direction of the rotation axis of the second conveying roller 121a is perpendicular to the first direction F1. In this way, when the second conveying roller 121a is driven to rotate by a related driving member, the material W carried by the second conveying roller 121a can move along the first direction F1 under the rotation of the second conveying roller 121a, thereby realizing the movement of the material W along the first direction F1. Figure 3 As an example, the second conveying unit 121 includes a plurality of second conveying rollers 121a. Of course, the number of second conveying rollers 121a provided in each second conveying unit 121 may be the same or different, and is not specifically limited here.

[0061] Exemplarily, the components driving the second conveying unit 121 to convey the material W along the first direction F1 may be a driving motor (not shown) and a belt transmission assembly (not shown), and the second conveying roller 121a may be driven to rotate by the driving motor and the belt transmission assembly. The component driving the second conveying unit 121 to perform lifting motion along the second direction F2 may be a lifting unit I, and the lifting unit I may be a hydraulic lifting mechanism, a pneumatic lifting mechanism, an electric lifting mechanism, or a scissor-type lifting mechanism, which is not specifically limited here.

[0062] During the lifting and lowering movement of the second conveying unit 121 along the second direction F2, the second conveying unit 121 can extend or retract relative to the target pallet T1. Specifically, when the second conveying unit 121 extends relative to the target pallet T1, the bearing surface of the second conveying unit 121 is located above the bearing surface of the target pallet T1. At this time, the second conveying unit 121 can receive the material W conveyed by the first conveying mechanism 110 along the first direction F1. Subsequently, when the second conveying unit 121 retracts relative to the target pallet T1, the bearing surface of the second conveying unit 121 is located below the bearing surface of the target pallet T1. At this time, the material W carried by the second conveying unit 121 is carried by the target pallet T1. That is, as the second conveying unit 121 performs the lifting and lowering movement along the second direction F2, the material W can be supported.

[0063] Thus, by configuring the first conveying mechanism 110 to include a plurality of first conveying units 111 arranged at intervals, when the initial pallet T0 carrying the material W is placed on the first conveying mechanism 110, the initial pallet T0 falls into the first accommodation space Q1 defined between the first conveying units 111 under the action of gravity, and the material W is carried on the first conveying unit 111, thereby achieving separation of the material W from the initial pallet T0. By configuring the second conveying mechanism 120 to include a plurality of second conveying units 121 arranged at intervals, when the target pallet T1 is placed on the second conveying mechanism 120, the target pallet T1 can fall into the second accommodation space Q2 defined between the second conveying units 121 under the action of gravity. Since the second conveying unit 121 is configured to be able to convey the material W along the first direction F1 and to perform lifting and lowering motion along the second direction F2, the second conveying unit 121 can receive the material W conveyed by the first conveying mechanism 110 at a position extending from the target pallet T1, and adjust the position of the material W relative to the target pallet T1 along the first direction F1, and then descend along the second direction F2, so that the material W is carried by the target pallet T1, thereby completing the pallet adding operation of the material W. Therefore, by using the pallet changing device 100 provided in the embodiment of the present application, the pallet removal operation and the pallet adding operation of the material W can be realized, thereby realizing the automatic pallet changing operation, thereby improving the pallet changing operation efficiency.

[0064] Figure 6 A schematic diagram of the three-dimensional structure of the first conveying mechanism 110 and the adjusting mechanism 130 cooperating with each other is shown; Figure 7 Shows Figure 6 A schematic diagram of the cross-sectional structure along the AA direction; for ease of explanation, only the contents related to the embodiments of the present application are shown.

[0065] In some embodiments, please refer to Figure 1 , and combined with reference Figure 6 and Figure 7The first conveying mechanism 110 further includes a first transfer unit 112. All the first conveying units 111 are arranged on the first transfer unit 112, and the first transfer unit 112 is used to transfer the first conveying unit 111 along the third direction F3. The first direction F1, the second direction F2 and the third direction F3 are perpendicular to each other. In the embodiment of the present application, the first direction F1 and the third direction F3 are both horizontal directions, and the second direction F2 is a vertical direction.

[0066] The first transfer unit 112 is a unit that carries and drives the first conveying unit 111 to move, and can transfer the first conveying unit 111 to different positions. Figure 6 and Figure 7 For example, the first transfer unit 112 may include a first drive member 112a, a first transmission assembly 112b, a first mounting member 112c and a first guide rail 112d, the first drive member 112a is transmission-connected to the input end of the first transmission assembly 112b, the output end of the first transmission assembly 112b is connected to the first mounting member 112c, all the first conveying units 111 are mounted on the first mounting member 112c, and the first mounting member is slidably connected to the first guide rail 112d along the third direction F3 through a slider (not shown in the figure). The first transmission assembly 112b may include a gear (not shown in the figure) and a rack (not shown in the figure) that are meshed and connected, the first drive member 112a may be a motor, the first drive member 112a is connected to the gear, and the rack is connected to the first mounting member 112c. Further, the tray changing device 100 may also include a first frame G1, and the first transfer unit 112 is arranged on the first frame G1.

[0067] In this way, by setting the first transfer unit 112, the first conveying unit 111 can be moved along the third direction F3, so that the position of the material W carried on the first conveying unit 111 in the third direction F3 can be adjusted, which is beneficial to convey the material W to the second conveying mechanism 120 according to the size and state of the material W.

[0068] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 6 The tray changing device 100 further includes an adjustment mechanism 130. The adjustment mechanism 130 is disposed on one side of the first conveying mechanism 110 along the third direction F3, and is used to cooperate with the first transfer unit 112 to adjust the posture of the material W carried by the first conveying unit 111.

[0069] The adjustment mechanism 130 is a mechanism that can be used to adjust the position of the material W. Since the first conveying unit 111 can move along the third direction F3 under the drive of the first transfer unit 112, that is, the adjustment mechanism 130 is located on the moving path of the first conveying unit 111 along the third direction F3, so that the material W carried by the first conveying unit 111 can be connected to the adjustment mechanism 130 during the process of following the first conveying unit 111 to move along the third direction F3, so that the adjustment mechanism 130 can be used to adjust the position of the material W. In this way, it is further beneficial to convey the material W to the second conveying mechanism 120 according to the size and state of different materials W.

[0070] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 6 The adjustment mechanism 130 includes a plurality of adjustment rollers 131 arranged along a first direction F1, and the extension direction of the rotation axis of the adjustment roller 131 is parallel to the second direction F2; the plurality of adjustment rollers 131 are used to support the material W carried by the first conveying unit 111 along a third direction F3 to adjust the posture of the material W.

[0071] In this way, since the adjustment roller 131 is rotatably arranged, after the material W abuts against the adjustment roller 131 and adjusts its posture, the first conveying unit 111 can be directly used to convey the material W along the first direction F1. At this time, the adjustment roller 131 rotates under the action of the material W, which is beneficial to conveying the material W.

[0072] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 6 The support changing device 100 further includes a first detection member J1 disposed on the adjustment mechanism 130 , and the first detection member J1 is used to detect whether the posture of the material W is in the target posture.

[0073] Specifically, a plurality of first detection members J1 may be provided along the first direction F1. Furthermore, the first detection member J1 may determine whether the posture of the material W is in the target posture by detecting whether the material W is in place. It can be understood that when the material W abuts against the adjustment roller 131, the detection member detects that the material W is in place, that is, it can be determined that the posture of the material W is in the target posture. Exemplarily, the first detection member J1 may be a detection member such as a photoelectric sensor or an infrared sensor, which is not specifically limited here. When the first detection member J1 detects that the posture of the material W is in the target posture, the first transfer unit 112 stops transferring the first conveying unit 111 to move along the third direction F3.

[0074] In this way, by providing the first detection member J1, it is not only beneficial to control the transfer distance of the first transfer unit 112, but also beneficial to adjust the posture of the material W, so as to adjust the posture of the material W to the desired target posture.

[0075] Of course, in some other embodiments, the material W may be made to abut against the adjustment roller 131 by presetting the transfer distance of the first transfer unit 112. The pre-set transfer distance may be determined according to different conditions of the material W, and is not specifically limited here.

[0076] In some embodiments, please refer to Figure 4 and Figure 7 The first conveying mechanism 110 further includes a limiting member 113. The limiting member 113 is disposed in the first accommodating space Q1, and the limiting member 113 is configured to limit the initial tray T0.

[0077] Specifically, the limiting member 113 defines a limiting channel p. Figure 4 When the pallet fork places the initial pallet T0 carrying the material W on the first conveying unit 111, the initial pallet T0 falls into the first accommodating space Q1 under the action of gravity, and the material W is carried on the first conveying unit 111. The protruding portion at the bottom of the initial pallet T0 is limited by the limiting member 113 via the limiting channel p, so that the initial pallet T0 is located in the first accommodating space Q1. Furthermore, the cross-sectional area of ​​the limiting channel p of the initial pallet T0 along the second direction F2 is first reduced and then remains unchanged, which is conducive to the protruding portion at the bottom of the initial pallet T0 entering the limiting channel p.

[0078] In this way, by providing the limiting member 113 , it is not only helpful to limit the initial pallet T0 accommodated in the first accommodating space Q1 , but also helpful for the pallet fork to place the initial pallet T0 between the first conveying units 111 .

[0079] Figure 8 A schematic diagram of the structure of the target tray T1, the first positioning member D1 and the second positioning member D2 in some embodiments of the present application is shown; for ease of explanation, only the content related to the embodiments of the present application is shown.

[0080] In some embodiments, please refer to Figure 5 and Figure 8 The pallet changing device 100 further includes a first positioning member D1 provided on one side of the target pallet T1 along the first direction F1, and the first positioning member D1 is located on a moving path of the material W along the first direction F1; and / or, the pallet changing device 100 further includes a second positioning member D2 provided on one side of the target pallet T1 along the third direction F3, and the first direction F1, the second direction F2 and the third direction F3 are perpendicular to each other.

[0081] Taking the first positioning member D1 as an example, which is arranged on the side of the target pallet T1 along the first direction F1 close to the first conveying mechanism 110, after the second conveying unit 121 receives the material W conveyed by the first conveying unit 111, the second conveying unit 121 descends along the second direction F2. Subsequently, the second conveying unit 121 can move the material W a certain distance away from the first conveying unit 111 along the first direction F1, so that the material W can abut against the first positioning member D1. Then, the second conveying unit 121 continues to descend along the second direction F2, and the material W is completely carried on the target pallet T1, completing the support operation. The situation where the first positioning member D1 is arranged on the side of the target pallet T1 away from the first conveying mechanism 110 along the first direction F1 can be understood by referring to the situation where the first positioning member D1 is arranged on the side of the target pallet T1 along the first direction F1 close to the first conveying mechanism 110, and no further description is given here. It should be noted that the distance that the second conveying unit 121 descends along the second direction F2 can be adjusted according to the actual use situation, and no specific limitation is made here.

[0082] Thus, by providing the first positioning member D1, the material W can be placed on the corresponding target pallet T1 with the same reference, which is beneficial to the turnover of the target pallet T1 carrying the material W. By providing the second positioning member D2, the material W is further positioned so that the material W can have substantially the same reference relative to the corresponding target pallet T1.

[0083] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 5 The second conveying mechanism 120 further includes a second transfer unit 122. All the second conveying units 121 are disposed on the second transfer unit 122, and the second transfer unit 122 is used to transfer the second conveying units 121 along the first direction F1.

[0084] The second transfer unit 122 is a unit that carries and drives the second conveying unit 121 to move, and can transfer the second conveying unit 121 to different positions. The second transfer unit 122 can be understood with reference to the first transfer unit 112, and the structures of the two can be the same or different. Figure 1 , Figure 2 and Figure 5 For example, the second transfer unit 122 may include a second guide rail 122a, and all second conveying units 121 are arranged on the aforementioned lifting unit I, and the lifting unit I is arranged on the second frame G2. A guide wheel E may be arranged at the bottom of the second frame G2, and the guide wheel E may move along the second guide rail 122a along the first direction F1. The relevant driving component may be connected to the second frame G2 to drive the second frame G2 to move along the first direction F1. In this way, the second transfer unit 122 can transfer the second conveying unit 121 along the first direction F1.

[0085] Thus, by providing the second transfer unit 122 , it is helpful to realize the continuous operation of material W turnover.

[0086] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 5 The tray changing device 100 further includes a second detection member J2 disposed on the transfer path of the second transfer unit 122, and the second detection member J2 is used to detect the transfer distance of the second transfer unit 122. Exemplarily, the second detection member J2 may be a distance sensor.

[0087] In this way, by providing the second detection member J2 , the transfer distance of the second transfer unit 122 can be determined, thereby facilitating the control of the transfer process of the second transfer unit 122 .

[0088] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 5 The tray changing device 100 further includes a third detection member J3 disposed on the transfer path of the second transfer unit 122, and the third detection member J3 is used to detect the contour of the target tray T1 and the material W carried on the target tray T1 to determine whether the target tray T1 is compatible with the material W. Exemplarily, the third detection member J3 may be a visual sensor.

[0089] Thus, by providing the third detection member J3, the tray replacement process of the material W can be made more reliable.

[0090] In some embodiments, the tray-changing device 100 further includes a buffer (not shown), which is disposed on the transfer path of the second transfer unit 122. The buffer is a component used to mitigate impact force and absorb energy.

[0091] In this way, by providing a buffer, the second transfer unit 122 can be protected, vibration can be reduced, and the stability of the transfer of the second transfer unit 122 can be improved, thereby achieving protection of the material W.

[0092] In some embodiments, please refer to Figure 1 and Figure 2 The tray changing device 100 further includes a fourth detection member J4, which is used to detect whether the target tray T1 exists on the second conveying mechanism 120. Exemplarily, the fourth detection member J4 can be a photoelectric sensor, an ultrasonic sensor, etc., which is not specifically limited here.

[0093] In this way, by providing the fourth detection member J4 , the target tray T1 can be replenished when the target tray T1 is not placed on the second conveying mechanism 120 , thereby achieving a continuous operation of replacing the tray of the material W, thereby improving the operating efficiency.

[0094] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 , all the first conveying units 111 are arranged into multiple rows along the first direction F1, and are arranged into multiple columns along the third direction F3; the first direction F1, the second direction F2 and the third direction F3 are perpendicular to each other; and / or, all the second conveying units 121 are arranged into multiple rows along the first direction F1, and are arranged into multiple columns along the third direction F3; the first direction F1, the second direction F2 and the third direction F3 are perpendicular to each other.

[0095] In this way, all the first conveying units 111 are arranged roughly in an array, which can not only improve the carrying capacity and carrying stability of the first conveying mechanism 110, but also help to form a first accommodating space Q1 for accommodating the initial pallet T0. All the second conveying units 121 are arranged roughly in an array, which can not only improve the carrying capacity and carrying stability of the second conveying mechanism 120, but also help to form a second accommodating space Q2 for accommodating the target pallet T1.

[0096] In some embodiments, please refer to Figure 1 and Figure 2 The tray changing device 100 further includes a controller 140, which is electrically connected to the first conveying mechanism 110 and the second conveying mechanism 120. The controller 140 is used to control the action of the first conveying mechanism 110 and the action of the second conveying mechanism 120. Further, the controller 140 is also electrically connected to the first detection member J1, the second detection member J2, the third detection member J3, and the fourth detection member J4. The controller 140 is also used to control the conveying action of the corresponding conveying unit and the transfer action of the corresponding transfer unit according to the detection signals of the above-mentioned detection members.

[0097] In this way, by providing the controller 140 , it is convenient to control the automatic and continuous operation of the tray changing device 100 , thereby further improving the operation efficiency.

[0098] In summary, in the tray changing device 100 provided in the embodiment of the present application, through the mutual cooperation between the first conveying mechanism 110, the second conveying mechanism 120, the adjustment mechanism 130 and the various detection parts, it is possible to be compatible with initial trays T0 of different types and sizes, automatically change different materials W to the target tray T1 with the same standard, and make the materials W after the tray change on the same basis. In this way, not only can the operating efficiency be improved, but also the turnover of materials W after the tray change is facilitated. For example, when storing materials W in a vertical storage manner, by using the tray changing device 100, materials W can be more safely and stably circulated, so that materials W can be put into storage with a unified basis, which is beneficial to subsequent operations on materials W. Subsequent operations on materials W may be loading, cutting and other operations, which are not specifically limited here.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
