Description

Technical Field

[0001] This utility model relates to the field of mother-daughter pallet fitting technology, and in particular to an automated mother-daughter pallet fitting device. Background Technology

[0002] Many products require palletizing for shipping due to their inherent characteristics. For example, bagged products in the chemical industry need to be packaged and shipped together with pallets to protect them from damage and contamination.

[0003] Pallets used for shipping are generally low-cost wooden pallets or easy-to-clean plastic pallets. These are called sub-pallets in the industry. After the goods are loaded onto the sub-pallets, they are stored on the shelves of the automated warehouse. Because the sub-pallets have poor load-bearing capacity, they are prone to deformation when left on the shelves for a long time. Therefore, it is necessary to place a strong load-bearing mother pallet under the sub-pallets.

[0004] Currently available pallet merging equipment can only handle pallet merging operations with pallets of the same specification. However, different customers have different requirements for product specifications and stacking types, so the specifications and dimensions of the pallets used for stacking are also different. Therefore, there is an urgent need to develop a pallet merging equipment that can adapt to pallets of different specifications. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an automated mother-daughter pallet merging device that can adapt to different specifications of sub-pallets.

[0006] Currently, there is no pallet-and-child pallet merging device on the market that can adapt to different sizes of child pallets. Based on actual needs, this solution proposes a guide plate adjustment device that can change the width of the space on the lifting conveyor that accommodates child or mother pallets, so that the guide plate adjustment device can be adjusted to a suitable width according to different sizes of child and mother pallets.

[0007] The technical solution adopted by this utility model is: an automated pallet-female pallet merging device, comprising: a sub-pallet conveyor for conveying sub-pallets from back to front, a female pallet conveyor for conveying female pallets in the front-back direction, a lifting conveyor that can connect with the sub-pallet conveyor and the female pallet conveyor when in the descending position, and a pallet merging machine for holding the sub-pallets on the lifting conveyor when in the ascending position. The sub-pallet conveyor, lifting conveyor, and mother pallet conveyor are arranged in sequence from back to front, and the pallet merging machine is located to the left or right of the lifting conveyor; A guide plate adjustment device is provided in the conveying area of ​​the lifting conveyor for adjusting the width of the space for accommodating the sub-pallet or the mother pallet.

[0008] Furthermore, in the aforementioned automated mother-daughter pallet consolidation device, the lifting conveyor includes: a base, a lifting frame mounted on the base via a lifting drive device, and the lifting frame being able to rise to a designated position and maintain at the designated position or descend to a lowered position and maintain at the lowered position via the lifting drive device; a conveyor line is provided on the lifting frame that can connect and convey with the daughter pallet conveyor and the mother pallet conveyor. The structure of the guide plate adjustment device is as follows: the first guide plate is set on the left side of the lifting frame through the first slide rail group, and the first slide rail group is positioned so that the first guide plate can move in the left and right directions through the first slide rail group; the second guide plate is set on the right side of the lifting frame through the second slide rail group, and the second slide rail group is positioned so that the second guide plate can move in the left and right directions through the second slide rail group.

During the process of the first guide plate and the second guide plate simultaneously moving closer together, the width of the space between the first guide plate and the second guide plate gradually decreases; during the process of the first guide plate and the second guide plate simultaneously moving away from each other while opening, the width of the space between the first guide plate and the second guide plate gradually increases.

[0009] Furthermore, in the aforementioned automated mother-daughter pallet fitting device, the structure of the adjusting drive mechanism includes: a lead screw supported on the lifting frame by a first bearing assembly, wherein the external thread section on the left side of the lead screw rotates in the opposite direction to the external thread section on the right side of the lead screw; The first guide plate has a first internal threaded hole for the external threaded section of the left side of the lead screw to screw into, and the second guide plate has a second internal threaded hole for the external threaded section of the right side of the lead screw to screw into. The lead screw, the first internal threaded hole, and the second internal threaded hole constitute a lead screw pair. When the external threaded section on the left side of the lead screw and the external threaded section on the right side of the lead screw have opposite directions of rotation, and all other parameters are the same, when the lead screw rotates in a certain direction, the first guide plate and the second guide plate move synchronously, with the same moving speed and opposite moving directions.

[0014] A second lifting baffle device is provided at the rear end of the mother pallet conveyor; The second lifting baffle device includes: a second lifting beam, on which at least one second baffle is fixedly installed. The second lifting beam is installed on the rear end of the frame of the mother pallet conveyor via a second lifting mechanism.

A more preferred embodiment is that the third receiving cavity is located at the vertical centerline of the second lifting beam.

[0017] Furthermore, in the aforementioned automated mother-child pallet merging device, each first baffle is mounted on the frame of the child pallet conveyor via its corresponding first vertical slide rail.

[0041] It should be noted that the terms "left", "right", "front", "back", "up", "down" etc., defined above indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description and facilitating the description of the relative positional relationship between the various components of this utility model, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Example 1

[0042] The automated mother-daughter pallet fitting device described in this embodiment, such as Figure 1 and Figure 3 As shown, it includes: a sub-pallet conveyor 1 for conveying sub-pallets from back to front, a mother pallet conveyor 3 for conveying mother pallets in the front-back direction, a lifting conveyor 2 that can connect with the sub-pallet conveyor 1 and the mother pallet conveyor 3 when it is in the descending position, and a pallet clamping machine 5 for holding the sub-pallets on the lifting conveyor 2 when it is in the ascending position.

[0043] The sub-pallet conveyor 1, lifting conveyor 2, and mother pallet conveyor 3 are arranged in sequence from back to front, and the pallet merging machine 5 is located to the left or right of the lifting conveyor 2.

[0044] A guide plate adjustment device is provided in the conveying area of ​​the lifting conveyor 2 to adjust the width of the space for accommodating sub-pallets or mother pallets, so that the space on the lifting conveyor 2 for accommodating sub-pallets or mother pallets can accommodate sub-pallets and mother pallets of different widths.

[0045] like Figure 9 and Figure 10 As shown, the lifting conveyor 2 in this embodiment includes: a base 24, a lifting frame 25 installed on the base 24 by a lifting drive device, and the lifting frame 25 can be raised to a designated position and maintained at the designated position or lowered to a lowered position and maintained at the lowered position by the lifting drive device; a conveyor line 21 is provided on the lifting frame 25 to be able to connect with the sub-pallet conveyor 1 and the mother pallet conveyor 3.

[0046] Among them, the sub-pallet conveying line on the sub-pallet conveyor 1, the mother pallet conveying line on the mother pallet conveyor 3, and the conveying line 21 on the lifting conveyor 2 all adopt roller conveyor lines. Roller conveyor lines are a mature structure in this industry, so their structure will not be described in detail here.

[0047] like Figure 9 and Figure 10 As shown, the structure of the guide plate adjustment device is as follows: a first guide plate 22 is disposed on the left side of the lifting frame 25 via a first slide rail assembly 221, and the first slide rail assembly 221 is positioned such that the first guide plate 22 can move in the left-right direction via the first slide rail assembly 221. A second guide plate 23 is disposed on the right side of the lifting frame 25 via a second slide rail assembly 231, and the second slide rail assembly 231 is positioned such that the second guide plate 23 can move in the left-right direction via the second slide rail assembly 231.

[0048] Preferably, the first slide rail group 221 consists of two sets of first horizontal slide rails. The rails in the first horizontal slide rails can be set on the lifting frame 25, and the sliders in the first horizontal slide rails can be set on the first guide plate 22. Similarly, the second slide rail group 231 preferably consists of two sets of second horizontal slide rails. The rails in the second horizontal slide rails can be set on the lifting frame 25, and the sliders in the second horizontal slide rails can be set on the second guide plate 23.

[0049] The first guide plate 22 and the second guide plate 23 are parallel, and the space between the first guide plate 22 and the second guide plate 23 is a space for accommodating a sub-pallet or a mother pallet. An adjustment drive mechanism is provided on the lifting frame 25 to simultaneously move the first guide plate 22 and the second guide plate 23 closer together or simultaneously move away from each other, thereby adjusting the width of the space between the first guide plate 22 and the second guide plate 23.

[0050] like Figure 10As shown, the structure of the adjustment drive mechanism described in this embodiment includes: a lead screw 82 supported on the lifting frame 25 by a first bearing assembly 821, wherein the external thread section on the left side of the lead screw 82 rotates in the opposite direction to the external thread section on the right side of the lead screw 82; The first guide plate 22 has a first internal threaded hole for the external threaded section of the left part of the lead screw 82 to be screwed in, and the second guide plate 23 has a second internal threaded hole for the external threaded section of the right part of the lead screw 82 to be screwed in; the lead screw 82, the first internal threaded hole, and the second internal threaded hole form a lead screw pair. When the lead screw 82 rotates in a certain direction, the first guide plate 22 and the second guide plate 23 move in opposite directions.

[0051] A more preferred method is to make the external threaded section on the left side of the lead screw 82 and the external threaded section on the right side of the lead screw 82 rotate in opposite directions, while keeping all other parameters the same. In this case, when the lead screw 82 rotates in a certain direction, the first guide plate 22 and the second guide plate 23 move synchronously, with the same moving speed and opposite moving directions. This allows for better control of the width of the space between the first guide plate 22 and the second guide plate 23.

[0052] A first drive motor 8 is fixedly mounted on the lifting frame 25. The output shaft of the first drive motor 8 transmits power to the lead screw 82 via a first belt drive, a first chain drive 81, or a first gear drive. In this embodiment, the first chain drive 81 is preferably used. In this case, the drive sprocket in the first chain drive 81 is fixed on the output shaft of the first drive motor 8, and the driven sprocket in the chain drive 81 is fixed on the lead screw 82.

[0053] Assuming that when the first drive motor 8 rotates forward, the first guide plate 22 and the second guide plate 23 move closer together, reducing the width of the space between the first guide plate 22 and the second guide plate 23, then when the first drive motor 8 rotates in reverse, the first guide plate 22 and the second guide plate 23 move further apart, increasing the width of the space between the first guide plate 22 and the second guide plate 23.

[0054] The guide plate adjustment device can flexibly and accurately adjust the distance between the first guide plate 22 and the second guide plate 223 so that the automated mother-daughter pallet merging equipment can adapt to the merging operation of daughter pallets and mother pallets of different specifications.

[0055] The working process of the above-mentioned automated mother-child pallet merging equipment is as follows: First, the loaded sub-pallet is conveyed to the conveyor line 21 of the lifting conveyor 2 via the sub-pallet conveyor 1. During this process, a first measuring light curtain for detecting the width of the sub-pallet can be set on the sub-pallet conveyor 1. The first measuring light curtain is connected to the control system, and the control system is also connected to the first drive motor 8. The width of the sub-pallet is measured by the first measuring light curtain and the measurement signal is fed back to the control system. The control system issues a command to the first drive motor 8 based on the measurement signal. The width of the space between the first guide plate 22 and the second guide plate 23 is adjusted by the forward or reverse rotation of the first drive motor 8 so that the width is adapted to the width of the sub-pallet. Next, after the sub-pallet arrives on the conveyor line 21 of the lifting conveyor 2, the lifting conveyor 2 rises to the rising position and remains in the rising position; Next, the assembling machine 5 forks hold the sub-pallet, and the lifting conveyor 2 descends to the lowering position and remains in the lowering position; Next, the mother pallet is conveyed to the conveyor line 21 of the lifting conveyor 2 via the mother pallet conveyor 3. During this process, a second measuring light curtain for detecting the width of the mother pallet can be set on the mother pallet conveyor 3. The second measuring light curtain is connected to the control system. The width of the mother pallet is measured by the second measuring light curtain and the measurement signal is fed back to the control system. The control system issues a command to the first drive motor 8 based on the measurement signal. The width of the space between the first guide plate 22 and the second guide plate 23 is adjusted by the forward or reverse rotation of the first drive motor 8 so that the width is adapted to the width of the mother pallet. Next, after the mother pallet arrives at the conveyor line 21 of the lifting conveyor 2, the lifting conveyor 2 rises until the child pallet can be supported on the mother pallet; Next, the tray releases the sub-pallet, and the lifting conveyor 2 descends to the lowering position and remains in the lowering position; Finally, the mother pallet carrying the goods and the sub-pallets is transported to the mother pallet conveyor 3 via the conveyor line 21 of the lifting conveyor 2, and then output by the mother pallet conveyor 3. Example 2

[0056] This embodiment is based on Embodiment 1, and designs the lifting drive device in the lifting conveyor 2 described in Embodiment 1.

[0057] like Figure 10 and Figure 11 As shown, the lifting drive device in this embodiment includes: at least one drive shaft and a second drive motor 9 fixedly mounted on the base 24. Each drive shaft is supported on the base 24 by its corresponding second bearing group. The output shaft of the second drive motor 9 transmits power to each drive shaft through a second belt drive, a second chain drive, or a second gear drive.

[0058] An eccentric wheel lifting mechanism is provided at the left end of each drive shaft and the left side of the lifting frame 25, and at the right end of each drive shaft and the right side of the lifting frame 25.

[0059] A better option is: such as Figure 10 As shown, the number of drive shafts is set to two: a first drive shaft 91 and a second drive shaft 93. The two drive shafts are symmetrically distributed front and back relative to the center line of the base 24 so that the lifting frame 25 can rise and fall more smoothly.

[0060] A better option is: such as Figure 10 As shown, the preferred transmission method for power transmission between the output shaft of the second drive motor 9 and each drive shaft is a second chain drive: a rear second chain drive 92 and a front second chain drive 94. In this case, the second drive motor 9 transmits power to the first drive shaft 91 through the rear second chain drive 92, that is, the drive sprocket in the rear second chain drive 92 is fixed to the output shaft of the second drive motor 9, and the driven sprocket in the rear second chain drive 92 is fixed to the first drive shaft 91. Similarly, the second drive motor 9 transmits power to the second drive shaft 93 through the front second chain drive 94, that is, the drive sprocket in the front second chain drive 94 is fixed to the output shaft of the second drive motor 9, and the driven sprocket in the front second chain drive 94 is fixed to the second drive shaft 93.

[0061] like Figure 10 and Figure 11 As shown, in this embodiment, the eccentric wheel lifting mechanism includes: a first mounting portion 95 disposed at the end of the drive shaft; the axle of the first roller 96 is fixed to the first mounting portion 95; the axis of the first roller 96 is parallel to the axis of the drive shaft but not on the same straight line; the lifting frame 25 has a first receiving cavity 251 for the first roller 96 to extend into and move around the axis of the drive shaft. The height of the first receiving cavity 251 is such that during the rotation of the drive shaft, the first roller 96 pushes the top surface of the first receiving cavity 251 upward to raise the lifting frame 25 or pushes the bottom surface of the first receiving cavity 251 downward to lower the lifting frame 25.

[0062] When the drive shaft rotates, because the first roller 96 is not on the same axis as the drive shaft, the rotation of the first roller 96 by the drive shaft forces the lifting frame 25 to rise or fall. Figure 11 The diagram shows the first roller 96 rotated to its lowest position by the drive shaft, at which point the lifting frame 25 is in its lowest descending position. Conversely, when the first roller 96 is rotated to its highest position by the drive shaft, the lifting frame 25 is in its highest ascending position, as shown below. Figure 12 As shown.

[0063] The lifting drive device adopts four sets of eccentric wheel lifting mechanisms, which are distributed at the four corners. The four sets of eccentric wheel lifting mechanisms are driven by the same drive motor, which enables the four corners of the lifting frame 25 to rise or fall synchronously. It has the advantages of smooth operation, reliability and flexibility, and is suitable for long-term high-frequency lifting work environment. Example 3

[0064] This embodiment is based on Embodiment 1, and designs the mixing machine 5 described in Embodiment 1.

[0065] like Figure 1 , Figure 13 and Figure 15 As shown, the structure of the mixing machine 5 in this embodiment includes: a base 53, a first fork tooth 51 arranged horizontally on the base 53 via a first bottom slide rail 511, and a second fork tooth 52 arranged horizontally on the base 53 via a second bottom slide rail 521.

[0066] In order to ensure that the first fork tooth 51 and the second fork tooth 52 can move to the left or to the right synchronously, this embodiment is provided with a synchronization plate 54. The rear part of the synchronization plate 54 is fixed to the first fork tooth 51, and the front part of the synchronization plate 54 is fixed to the second fork tooth 52.

[0067] A fork drive device is provided on the base 53 to drive the first fork tooth 51 and the second fork tooth 52 to slide synchronously to the left or synchronously to the right. For example... Figure 13 and Figure 14 As shown, the structure of the fork drive device in this embodiment is as follows: a fifth drive motor 57 is fixedly installed on the base 53, a gear 56 is fixedly installed on the output shaft of the fifth drive motor 57, and a rack 55 is installed on the side wall of the first fork tooth 51 or the second fork tooth 52. The rack 55 meshes with the gear 56 to form a rack and pinion transmission.

[0068] A preferred embodiment is to cover the gear 56 with a housing 561 to protect the gear 56 from contamination during use and to improve the service life of the gear rack. The housing 561 can be fixed to the housing of the fifth drive motor 57.

[0069] The sub-pallet has a gap area for the insertion of the first fork 51 and the second fork 52. The following description assumes the pallet assembly machine 5 is located to the left of the lifting conveyor 2. When the lifting conveyor 2 carrying the sub-pallet rises to the rising position and remains there, the first fork 51 and the second fork 52 move to the right via the fork drive device, inserting into the gap area on the sub-pallet for insertion. At this time, the lifting conveyor 2 descends, while the sub-pallet remains on the first fork 51 and the second fork 52.

[0070] After the automated mother-daughter pallet merging equipment completes the merging process, the mother pallet carrying the goods and the daughter pallets enters the mother pallet conveyor 3. In order to ensure that the overall height, width, and length of the mother pallet carrying the goods and the daughter pallets after merging do not exceed the specified range, this embodiment is equipped with a frame-type size inspection device 4 at the mother pallet conveyor 3 for detecting whether the height, width, and length of the merged goods after stacking the goods, daughter pallets, and mother pallets exceed the specified range.

[0071] On the frame-type size inspection device 4, a first pair of photoelectric sensors is set at the highest height of the frame-type frame to detect whether the height of the palletized goods exceeds the limit. Two sets of second photoelectric sensors are set at both ends of the maximum width of the frame-type frame to detect whether the width of the palletized goods exceeds the limit. Two sets of third photoelectric sensors are set at both ends of the maximum length of the frame-type frame to detect whether the length of the palletized goods exceeds the limit. After the palletized goods pass the size inspection, they are transported into the warehouse. Example 4

[0072] The automated mother-daughter pallet fitting device described in this embodiment, such as Figure 1 and Figure 3 As shown, it includes: a sub-pallet conveyor 1 for conveying sub-pallets from back to front, a mother pallet conveyor 3 for conveying mother pallets in the front-back direction, a lifting conveyor 2 that can connect with the sub-pallet conveyor 1 and the mother pallet conveyor 3 when it is in the descending position, and a pallet clamping machine 5 for holding the sub-pallets on the lifting conveyor 2 when it is in the ascending position.

[0073] The sub-pallet conveyor 1, lifting conveyor 2, and mother pallet conveyor 3 are arranged sequentially from back to front, and the pallet merging machine 5 is located to the left or right of the lifting conveyor 2. After the relative positions of the sub-pallet conveyor 1, lifting conveyor 2, mother pallet conveyor 3, and pallet merging machine 5 are adjusted and determined, they are all fixed to the ground with expansion bolts.

[0074] A guide plate adjustment device is provided in the conveying area of ​​the lifting conveyor 2 for adjusting the width of the space for accommodating the sub-pallet or the mother pallet.

[0075] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, in this embodiment, a first lifting baffle device 6 is provided at the front end of the sub-pallet conveyor 1.

[0076] The first lifting baffle device 6 includes: a first lifting beam 64, on which at least one first baffle 61 is fixedly disposed. The first lifting beam 64 is disposed on the front end of the frame 11 of the sub-pallet conveyor through a first lifting mechanism, and each first baffle 61 can be raised by the first lifting mechanism to block the sub-pallet conveyor 1 from being connected to the lifting conveyor 2 or lowered to not interfere with the sub-pallet conveyor 1 and the lifting conveyor 2 being connected.

[0077] During the process of conveying sub-pallets from back to front, the descending first baffles 61 will not obstruct the sub-pallets from being conveyed from the sub-pallet conveyor 1 to the lifting conveyor 2.

[0078] During the process of conveying the mother pallet from front to back, in order to prevent the mother pallet from continuing to move backward after being conveyed from the mother pallet conveyor 3 to the lifting conveyor 2, the rising first baffles 61 block the mother pallet from continuing to move backward, so as to ensure that the mother pallet can be stopped precisely on the lifting conveyor 2.

[0079] like Figure 4 and Figure 5 As shown, the structure of the first lifting mechanism in this embodiment is as follows: a third drive motor 65 is fixedly mounted on the frame 11 of the sub-pallet conveyor; a second mounting part 67 is fixedly mounted on the output shaft of the third drive motor 65; the axle of the second roller 66 is fixed on the second mounting part 67; the axis of the second roller 66 is parallel to the axis of the output shaft of the third drive motor 65 but not on the same straight line; the first lifting beam 64 has a second receiving cavity 641 for the second roller 66 to extend into and move around the axis of the output shaft of the third drive motor 65. The height of the second receiving cavity 641 is such that during the rotation of the output shaft of the third drive motor 65, the second roller 66 pushes the top surface of the second receiving cavity 641 upward to raise the first lifting beam 64 or pushes the bottom surface of the second receiving cavity 641 downward to lower the first lifting beam 64.

[0080] A more preferred embodiment is that the second receiving cavity 641 is located at the vertical centerline of the first lifting beam 64.

[0081] like Figure 5 As shown, the second roller 66 is driven to the highest position by the output shaft of the third drive motor 65. At this time, each of the first baffles 61 is in the highest position. At this time, the sub-pallets on the sub-pallet conveyor 1 cannot pass over each of the first baffles 61 to enter the lifting conveyor 2. The mother pallets transported from the mother pallet conveyor 3 to the lifting conveyor 2 are also blocked by each of the first baffles 61 and will not pass over each of the first baffles 61 to enter the sub-pallet conveyor 1 under the action of inertial force.

[0082] Conversely, when the second roller 66 is driven to the lowest position by the output shaft of the third drive motor 65, each of the first baffles 61 is in the lowest descending position. At this time, the sub-pallets on the sub-pallet conveyor 1 are not interfered with by each of the first baffles 61 and can be conveyed to the lifting conveyor 2.

[0083] In order to guide the first baffles 61 to rise and fall, such as Figure 2 , Figure 4 and Figure 5 As shown, each first baffle 61 is mounted on the frame 11 of the sub-pallet conveyor via its corresponding first vertical slide rail.

[0084] The track 62 in the first vertical slide rail can be mounted on the first baffle 61, and the slider 63 in the first vertical slide rail can be mounted on the frame 11 of the sub-pallet conveyor. The number of sliders 63 in the first vertical slide rail can be one or more.

[0085] like Figure 1 , Figure 3 , Figure 6 and Figure 7 As shown, in this embodiment, a second lifting baffle device 7 is provided at the rear end of the mother pallet conveyor 3.

[0086] The second lifting baffle device 7 includes: a second lifting beam 74, on which at least one second baffle 71 is fixedly installed. The second lifting beam 74 is installed on the rear end of the frame 31 of the mother pallet conveyor through a second lifting mechanism. Each second baffle 71 can be raised by the second lifting mechanism to block the mother pallet conveyor 3 from docking with the lifting conveyor 2 or lowered to not interfere with the docking of the mother pallet conveyor 3 and the lifting conveyor 2.

[0087] During the process of conveying the mother pallet from front to back, the descending second baffles 71 will not obstruct the mother pallet from being conveyed from the mother pallet conveyor 3 to the lifting conveyor 2.

[0088] During the process of conveying sub-pallets from back to front, in order to prevent the sub-pallets conveyed from the sub-pallet conveyor 1 to the lifting conveyor 2 from continuing to move forward, the rising second baffles 71 block the sub-pallets from continuing to move forward, so as to ensure that the sub-pallets can be stopped precisely on the lifting conveyor 2.

[0089] like Figure 6 and Figure 7As shown, the structure of the second lifting mechanism in this embodiment is as follows: a fourth drive motor 75 is fixedly mounted on the frame 31 of the mother pallet conveyor; a third mounting part 77 is fixedly mounted on the output shaft of the fourth drive motor 75; the axle of the third roller 76 is fixed on the third mounting part 77; the axis of the third roller 76 is parallel to the axis of the output shaft of the fourth drive motor 75 but not on the same straight line; the second lifting beam 74 has a third receiving cavity 741 for the third roller 76 to extend into and move around the axis of the output shaft of the fourth drive motor 75. The height of the third receiving cavity 741 is such that during the rotation of the output shaft of the fourth drive motor 75, the third roller 76 pushes the top surface of the third receiving cavity 741 upward to raise the second lifting beam 74 or pushes the bottom surface of the third receiving cavity 741 downward to lower the second lifting beam 74.

[0090] A more preferred embodiment is that the third receiving cavity 741 is located at the vertical centerline of the second lifting beam 74.

[0091] like Figure 7 As shown, the third roller 76 is driven to the highest position by the output shaft of the fourth drive motor 75. At this time, each of the second baffles 71 is in the highest position. At this time, the mother pallet on the mother pallet conveyor 3 cannot pass over each of the second baffles 71 to enter the lifting conveyor 2. The child pallets transported from the child pallet conveyor 1 to the lifting conveyor 2 are also blocked by each of the second baffles 71 and will not pass over each of the second baffles 71 to enter the mother pallet conveyor 3 under the action of inertial force.

[0092] Conversely, when the third roller 76 is driven to the lowest position by the output shaft of the fourth drive motor 75, each of the second baffles 71 is in the lowest descending position. At this time, the mother pallet on the mother pallet conveyor 3 is not interfered with by each of the second baffles 71 and can be conveyed to the lifting conveyor 2.

[0093] To guide the rise and fall of each of the second baffles 71, such as Figure 6 and Figure 7 As shown, each second baffle 71 is mounted on the frame 31 of the mother pallet conveyor via its corresponding second vertical slide rail.

[0094] The second vertical slide rail 72 can be mounted on the second baffle 71, and the slider 73 in the second vertical slide rail can be mounted on the frame 31 of the mother pallet conveyor. The number of sliders 73 in the second vertical slide rail can be one or more.

[0095] The automated pallet-female pallet merging device described in this embodiment uses liftable second baffles 71 to ensure that the female pallet is positioned on the lifting conveyor 2 after being transported from the female pallet conveyor 1 to the lifting conveyor 2, thus positioning the female pallet on the lifting conveyor 2. Similarly, liftable first baffles 61 ensure that the female pallet is positioned on the lifting conveyor 2 after being transported from the female pallet conveyor 3 to the lifting conveyor 2, thus positioning the female pallet on the lifting conveyor 2. Ultimately, this ensures that the female pallet on the merged goods is directly above the female pallet, guaranteeing the neatness of the merged goods.

[0096] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any modifications or equivalent changes made based on the technical essence of the present utility model shall still fall within the scope of protection claimed by the present utility model.
