Description

Technical Field

[0001] This invention relates to the field of logistics loading and unloading equipment technology, and in particular to a parallel container posture adjustment device. Background Technology

[0002] Many products rely on cardboard boxes for transportation, such as the tobacco industry using corrugated cardboard boxes to package cigarettes, and the dairy industry using cardboard boxes to package milk. Boxed materials are generally transported using vans. During loading, boxed materials need to be arranged in different configurations according to the size of the van to maximize the use of van space, increase the loading rate, and ensure that the goods are stacked securely to prevent them from falling and getting damaged during transportation.

[0003] Currently, loading of boxed materials mainly relies on manual labor. During manual loading, the boxes are rearranged into different positions for stacking, which is not only labor-intensive but also inefficient. To address this issue, some existing technologies have proposed automated loading of boxed materials using mechanical equipment. However, most of these solutions lack a mechanism for adjusting the position of the boxed materials, resulting in lower utilization of truck space compared to manual loading.

[0004] Existing technologies include separate research on box posture adjustment techniques, primarily employing methods such as lifting and rotation, clamping and rotation, and adsorption and rotation. The drawback of using these techniques is the numerous steps involved. For example, lifting and rotating to adjust the box posture requires three steps: lifting, rotating, and lowering the box. This cumbersome process limits the efficiency of posture adjustment. Furthermore, existing technologies can only achieve single-position adjustments. Additionally, the process flow for adjusting box posture in existing technologies is primarily sequential, meaning the next box can only be adjusted after the previous one has been completed, resulting in low efficiency. For instance, Chinese patent document CN202411754017.6 discloses a conveying device for box posture adjustment, which uses a combination of lifting and rotation and clamping and rotation to achieve box posture adjustment. However, this patented solution has the following drawbacks: (1) The use of lifting rotation and clamping rotation to adjust the posture of the box requires many steps, which limits the adjustment efficiency; (2) The process steps are arranged in series, and the next box can only enter the adjustment station for posture adjustment after the previous box has been adjusted, which limits the work efficiency. For example, Chinese patent document CN202411076367.1 discloses an adsorption box flipping mechanism. This patented solution can continuously flip the carton 90°, but this patented solution can only achieve a single flip of the carton and cannot meet the posture requirements required for loading the carton.

[0005] In summary, a technical solution is needed that can efficiently adjust the posture of boxed materials and simultaneously achieve automated loading. Summary of the Invention

[0006] In view of this, embodiments of the present invention provide a parallel box posture adjustment device to solve the problems of the lack of equipment in the prior art that can simultaneously adjust the posture of boxed materials and automatically load them, as well as the cumbersome operation steps of existing posture adjustment technology, which can only achieve a single posture adjustment of the box at each moment, resulting in low posture adjustment efficiency.

[0022] Figure 1 This is a schematic diagram of the stacking of box-type material wagons. To improve the loading rate of the wagons, the box-type materials need to be adjusted to various positions during the loading process, for example... Figure 1 Of the postures A, B, and C shown, posture B requires the most in practical applications, followed by posture A, while posture C requires the fewest and is only needed on the top layer of the stack.

[0023] Figure 2 This is a schematic diagram of a parallel box-type attitude adjustment device provided in an embodiment of the present invention. To make the present invention clearer, the front-back and left-right directions of the parallel box-type attitude adjustment device of the present invention are defined as follows: Figure 2 As shown, the material input and output direction of the parallel box-type multi-posture adjustment device, pointed to by arrow Y, is the front-to-back direction, and the horizontal direction, perpendicular to the front-to-back direction, pointed to by arrow X, is the left-to-right direction.

[0024] like Figure 2 As shown in the figure, the parallel box posture adjustment device provided in this embodiment of the invention includes: a rear roller conveying assembly 1, a right roller conveying assembly 2, a left roller conveying assembly 10, a box-turning assembly 11, and a flipping assembly; The left roller conveying assembly 10 and the right roller conveying assembly 2 each have two rows of rollers in the same horizontal plane. The first row of rollers of the left roller conveying assembly 10 and the right roller conveying assembly 2 are symmetrically arranged on both sides of the roller conveying direction of the rear roller conveying assembly 1. The conveying surfaces of the rear roller conveying assembly 1, the left roller conveying assembly 10, and the right roller conveying assembly 2 are coplanar, and the roller axial direction of the left roller conveying assembly 10 and the right roller conveying assembly 2 is perpendicular to the roller axial direction of the rear roller conveying assembly 1. The gearbox assembly 11 includes a gearbox plate 1103 disposed above the conveying surface of the rear roller conveyor assembly 1 (see...). Figure 15 The dialing assembly 11 is configured to cause the dialing plate 1103 to reciprocate in the left and right directions, so as to successively pull the box-shaped materials continuously input on the rear roller conveyor assembly 1 onto the first row of rollers of the left roller conveyor assembly 10 and the right roller conveyor assembly 2. A flipping assembly is provided between the two rows of rollers of the left roller conveyor assembly 10 and the right roller conveyor assembly 2. The flipping assembly is used to flip the box-shaped material on the first row of rollers of the left roller conveyor assembly 10 and the right roller conveyor assembly 2 by 90° in the front-to-back direction, so as to flip the box-shaped material onto the second row of rollers of the left roller conveyor assembly 10 / right roller conveyor assembly 2.

[0025] Figure 3 This is a schematic diagram of the device of the present invention adjusting the first posture A of the boxed material. The posture adjustment process is as follows: S11: The rear roller conveyor assembly 1 conveys the Nth box-type material 14 forward to the predetermined position and stops. At this time, the flipping assembly is waiting below the first row of roller conveying surfaces of the right roller conveyor assembly 2; where N is a positive integer, indicating the sequence number of the currently input box-type material 14. Preferably, such as Figure 2 As shown in the figure, the device provided in the embodiment of the present invention may further include a rear blocking component 12. The rear blocking component 12 is disposed at the output end of the rear roller conveying component 1 and is used to stop and position the box material 14 conveyed forward on the rear roller conveying component 1. After the Nth box material 14 is stopped by the rear blocking component 12, step S12 is executed.

[0026] S12: The box-shaped material 14 is moved to the right by the box-shaped material 11 and onto the first row of rollers of the right roller conveyor 2. At the same time, the N+1th box-shaped material 14 is conveyed to the predetermined position and stopped by the rear roller conveyor 1.

[0027] S13: The right-side flipping component flips the Nth box material on the first row of rollers of the right roller conveying component 2 forward by 90°, and the Nth box material 14 is transferred to the second row of rollers of the right roller conveying component 2. The Nth box material 14 is adjusted from the initial posture at the time of input to posture A. During this process, the box-shaped material 14 is moved to the left by the box-shaped material 11 to the first row of rollers of the left roller conveyor 10, while the N+2 box-shaped material 14 is conveyed to the predetermined position and stopped by the rear roller conveyor 1.

[0028] S14: The second row of rollers of the right roller conveyor assembly 2 outputs the Nth box-type material 14 to the middle (between the second row of rollers of the right roller conveyor assembly 2 and the left roller conveyor assembly 10); At the same time, the flipping component on the left flips the N+1th box material on the first row of rollers of the left roller conveying component 10 forward by 90°, and the N+1th box material 14 is transferred to the second row of rollers of the left roller conveying component 10. The N+1th box material 14 is adjusted from the initial posture at the time of input to posture A. During this process, the box-shaped material 14 is moved to the right by the N+2th box-shaped material 14 onto the first row of rollers of the right roller conveyor assembly 2, while the N+3rd box-shaped material 14 is conveyed to the predetermined position and stopped by the rear roller conveyor assembly 1.

[0029] S15: The second row of rollers of the left roller conveyor assembly 10 outputs the (N+1)th box material 14 to the middle. At the same time, the right-side flipping assembly performs an action similar to that described in S12 on the (N+2)th box material 14, and the box-turning assembly 11 turns the (N+3)th box material 14, and so on... As described in steps S11-S15, the device provided in this embodiment of the invention can achieve posture adjustment of boxed materials without interrupting the conveying process. When used between the loading platform and the cargo box of the transport vehicle, the device connects to a conveying device (e.g., a conveyor) that transports materials into the cargo compartment of the transport vehicle via the output ends of the second row of rollers of the left roller conveyor assembly 10 and the right roller conveyor assembly 2. This enables automatic loading and posture adjustment of materials. Furthermore, the reciprocating leftward and rightward movement of the box-turning assembly 11 moves the newly input boxed material 14. All movements of the box-turning assembly 11 are working strokes, with no wasted time. The left and right flipping assemblies alternately flip the boxed material 14, operating in parallel without interference. This structural design and material conveying control process greatly improve the posture adjustment speed of the boxed materials, resulting in high efficiency in posture adjustment operations.

[0030] The following is a detailed description of each part of the parallel box attitude adjustment device of the present invention.

[0031] Figure 4 This is a schematic diagram of the right roller conveyor assembly in an embodiment of the present invention, as shown below. Figure 4 As shown, the right roller conveyor assembly 2 includes: a first roller support 201, a first electric roller 202, a first roller 211, a second roller support 203, a second electric roller 210, a second roller 204, a third roller support 205, a first multi-wedge belt 207, a constraint roller 208, a laser rangefinder 209, and a laser rangefinder support 206; The first roller support 201, the second roller support 203, and the third roller support 205 are fixedly installed in the same horizontal plane along the front-to-back direction, and the second roller support 203 is located between the first roller support 201 and the third roller support 205; the first roller support 201, the second roller support 203, and the third roller support 205 are fixedly connected to the frame of the parallel box attitude adjustment device (not shown in the figure).

[0032] One axial end of the first electric roller 202 and the first roller 211 are fixedly connected to the first roller bracket 201, and the other end is fixedly connected to the second roller bracket 203, forming the first row of rollers; the first electric roller 202 and the first roller 211 are connected by a first multi-wedge belt 207, and the first electric roller 202 is used to drive the first roller 211. The second roller 204 and the second electric roller 210 are both fixedly connected at one axial end to the second roller bracket 203 and at the other end to the third roller bracket 205, forming the second row of rollers; the second roller 204 and the second electric roller 210 are connected by a first multi-wedge belt 207, and the second electric roller 210 is used to drive the rotation of multiple second rollers 204; The constraint roller 208 is movably connected to one end of the rear roller conveying assembly 1 on the third roller support 205. The constraint roller 208 can rotate around its vertical axis. The position of the constraint roller 208 can be adjusted according to the actual situation to achieve the best motion constraint on the box material. The laser rangefinder bracket 206 is movably connected to the third roller bracket 205, and the laser rangefinder 209 is fixedly connected to the laser rangefinder bracket 206. The detection direction of the laser rangefinder 209 can be adjusted according to the actual situation to achieve the best detection of the movement of the box material.

[0033] Combination Figure 2 Since the left roller conveyor assembly 10 and the right roller conveyor assembly 2 are symmetrical, it is obvious that the structure of the left roller conveyor assembly 10 can... Figure 4 The structure of the right roller conveyor assembly 2 shown can be obtained by mirroring it from left to right, and will not be described in detail here.

[0034] In this embodiment, when the box assembly 11 moves the Nth box material 14 to the right, looking in the input direction, the first row of rollers of the right roller conveying assembly 2 can be driven to rotate clockwise, and the first row of rollers conveys to the right. This allows the box material 14 to continue to be conveyed to the right to the designated position when it is moved to the top. The second row of rollers can rotate counterclockwise independently of the first row of rollers to output materials to the left. The two rows of rollers are controlled independently and can execute different material conveying steps at the same time, which can improve the material conveying efficiency.

[0037] The electric cylinder assembly 4 includes a second bearing housing 401, a servo motor 402, and an electric cylinder 403. The second bearing housing 401 is fixedly installed below the left roller conveyor assembly 10 and the right roller conveyor assembly 2. One end of the electric cylinder 403 is rotatably connected to the second bearing housing 401, and the other end is rotatably connected to the L-shaped fork 301. The servo motor 402 is fixedly connected to the electric cylinder 403 and is used to drive the electric cylinder 403 to extend and retract. The electric cylinder 403 can also be other devices that can extend and retract, such as a pneumatic cylinder.

[0038] The projection position of the fork teeth of the L-shaped fork carriage 301 in the horizontal plane corresponds to the roller gap of the left roller conveyor assembly 10 / right roller conveyor assembly 2. The fork carriage rotating assembly 3 is configured such that: before the box-type material is pushed onto the first row of rollers of the left roller conveyor assembly 10 / right roller conveyor assembly 2 by the box-type material pusher assembly 11, one side of the L-shaped fork carriage 301 is located below the first row of rollers; and after the box-type material is pushed onto the first row of rollers of the left roller conveyor assembly 10 / right roller conveyor assembly 2 by the box-type material pusher assembly 11, the L-shaped fork carriage 301 rotates around the axis of the first bearing seat 302 until the other side of the L-shaped fork carriage 301 is placed below the second row of rollers of the left roller conveyor assembly 10 / right roller conveyor assembly 2.

[0039] Figure 6 This is a schematic diagram showing two states of the flipping component before and after flipping in an embodiment of the present invention. For ease of description, [the following is used]. Figure 6 The two states are defined as 0° and 90°. When the electric cylinder 403 extends under the drive of the servo motor 402, the fork rotating assembly 3 is in the position... Figure 6 In the 0° state shown on the left, one side of the L-shaped fork 301 is embedded between the first row of rollers of the left / right roller conveyor assembly; when the electric cylinder 403 retracts under the drive of the servo motor 402, the L-shaped fork 301 rotates around the axis of the first bearing seat 302, eventually rotating to... Figure 6As shown on the right, in the 90° state, the other side of the L-shaped fork 301 is embedded between the second row of rollers of the left / right roller conveyor assembly. When the fork rotation assembly 3 switches from the 0° state to the 90° state, it can realize the 90° rotation of the box material 14.

[0040] In some embodiments, such as Figure 2 As shown, the parallel box attitude adjustment device provided by the present invention may further include: a swing wheel reversing component 13, which is disposed on the output side of the rear roller conveying component 1 and located between the second row of rollers of the left roller conveying component 10 and the right roller conveying component 2.

[0041] Figure 7 This is a schematic diagram of the structure of the balance wheel reversing assembly in an embodiment of the present invention, as shown below. Figure 7 As shown, the balance wheel reversing assembly 13 includes a housing 1302 and a plurality of balance wheels 1301; the balance wheels 1301 and the housing 1302 are fixedly connected to the frame of a parallel box-type attitude adjustment device (not shown in the figure). The axis of the balance wheel 1301 is along the vertical direction, and the balance wheel 1301 can rotate around its axis along... Figure 7 The balance wheel 1301 rotates clockwise or counterclockwise in direction a, as shown in the diagram. Several drive rollers 13011 with horizontal axes are provided on the top surface of the balance wheel 1301. Each drive roller 13011 on the balance wheel 1301 can rotate in the same direction around its axis. Figure 7 The direction b shown can be rotated forward or backward to assist in conveying the boxed materials on it. For ease of description, the drive roller 13011 will be referred to as moving along... Figure 7 Rotation in the middle b direction is defined as the forward rotation of the drive roller 13011, which moves the drive roller 13011 along... Figure 7 The reverse rotation in the middle b direction is defined as the reverse rotation of the drive roller 13011.

[0042] In this embodiment of the invention, when the device includes a balance wheel reversing assembly 13, the descriptions in S11-S15 above are as follows: Figure 3 In the posture A adjustment process shown, in S14, before the second row of rollers of the right roller conveyor assembly 2 outputs the Nth box-shaped material 14 to the swing wheel reversing assembly 13, Figure 3 The balance wheel reversing assembly 13 in the middle Figure 7 After rotating 90° counterclockwise along direction a in the initial state shown, the drive roller 13011 is controlled to rotate clockwise, so that the drive roller 13011 is in the same output direction as the second row of rollers of the right roller conveyor assembly 2, thus preparing in advance to participate in the confluence conveying of the box-shaped material 14 from right to left. Similarly, before the second row of rollers of the left roller conveyor assembly 10 outputs the N+1th box-shaped material 14 to the swing wheel reversing assembly 13 in S15, Figure 3 The balance wheel reversing assembly 13 in the middle Figure 7The initial state shown is rotated 90° clockwise along direction a, and the driving roller rotates forward, so that the driving roller 13011 is in the same output direction as the second row of rollers of the left roller conveying assembly 10, thus preparing in advance to participate in the confluence conveying of the box material 14 from left to right. Subsequently, when the second row of rollers of the right roller conveying assembly 2 and the swing wheel reversing assembly 13 output the box material 14 in attitude A to the middle of the swing wheel reversing assembly 13, after the above step S14, the following steps are also included: S16: Balance wheel reversing assembly 13 rapidly rotates back Figure 7 The initial state is shown; During this process, the drive roller 13011 is stationary and does not rotate, and will not drive the box material 14 on the upper part of the swing wheel reversing component 13.

[0043] S17: The swing wheel reversing assembly 13 will drive the roller 13011 to rotate forward, and output the box material 14 in posture A forward.

[0044] The following uses a box-type material conveyed to the right roller conveyor assembly 2 as an example to illustrate the process of adjusting it to the second posture B during the conveying process using the device provided by the present invention.

[0045] Figure 8 This is a schematic diagram of the device of the present invention adjusting the boxed material in a second posture B. The posture adjustment process is as follows: S21: The rear roller conveyor assembly 1 conveys the box material 14 in its initial posture forward to the predetermined position and stops. At this time, one side of the L-shaped fork 301 is embedded between the first row of rollers of the right roller conveyor assembly 2. Alternatively, the rear blocking component 12 can be used to stop the box-shaped material 14 conveyed by the rear roller conveying component 1 at a predetermined position. Before step S21, the rear blocking component 12 is raised in advance to prepare to block the material.

[0046] S22: The box assembly 11 moves the box material 14 in its initial position to the right onto the first row of rollers of the right roller conveyor assembly 2.

[0047] S23: The fork rotating assembly 3, pulled by the right electric cylinder assembly 4, rotates the box material 14 in its initial posture forward by 90° to obtain the box material 14 in posture A. The box material 14 in posture A is then transferred to the second row of rollers of the right roller conveyor assembly 2.

[0048] S24: The second row of rollers of the right roller conveyor assembly 2 conveys the box-shaped material 14 in posture A to the left at a speed of V1. At the same time, the swing wheel reversing assembly 13 maintains... Figure 7In the initial state, the drive roller 13011 is controlled to rotate forward at a speed of V2. During this process, the left end of the box material 14 in posture A gradually rotates to the right under the combined action of speeds V1 and V2. At the same time, under the combined action of the constraint roller 208, the box material 14 in posture A finally rotates horizontally by 90° during the conveying process and becomes the box material 14 in posture B for output.

[0049] Obviously, for the box material 14 conveyed by the right roller conveyor assembly 2, after step S24, the box material 14 in posture B will be output to the right side by the swing wheel reversing assembly 13; if in step S24 the second row of rollers of the left roller conveyor assembly 10 conveys the box material 14 in posture A to the right at a speed V1', then the swing wheel reversing assembly 13 will also maintain Figure 7 In the initial state, the drive roller 13011 is controlled to rotate forward at a speed of V2. After step S24, the box material 14 in attitude B will be output from the left side of the swing wheel reversing component 13, which will not be described in detail here.

[0050] As can be seen from the process steps S21 to S24 above, the present invention completes the adjustment from posture A to posture B during the conveying process through speed synthesis. The beneficial effects are: continuous posture adjustment of box-type materials is completed during conveying, the material conveying and posture adjustment are highly efficient, and the problem of cumbersome action steps in the existing posture adjustment technology, which can only achieve a single posture adjustment of the box at each moment, and the low efficiency of posture adjustment operation is solved.

[0051] In some embodiments, such as Figure 2 As shown, the parallel box attitude adjustment device provided by the present invention further includes: a front roller conveying assembly 5, which is disposed on the output side of the swing wheel reversing assembly 13. The front roller conveying assembly 5 is used to output the material output by the swing wheel reversing assembly 13 in a forward direction.

[0052] Figure 9 This is a schematic diagram of the front roller conveying assembly in an embodiment of the present invention. Figure 9As shown, the front roller conveying assembly 5 includes a fourth roller support 501, a fifth roller support 503, multiple third rollers 502, a third electric roller 504, and a second multi-wedge belt 505. The fourth roller support 501 and the fifth roller support 503 are fixedly connected to the frame of a parallel box-type attitude adjustment device (not shown). The fifth roller support 503 and the fourth roller support 501 are fixedly installed on the left and right sides of the same horizontal plane. One end of each of the third rollers 502 and the third electric roller 504 is fixedly connected to the fourth roller support 501, and the other end is fixedly connected to the fifth roller support 503. The third rollers 502 and the third electric roller 504 are connected via the second multi-wedge belt 505. The third electric roller 504 drives the multiple third rollers 502 to rotate, thereby enabling the conveying of the box-shaped material 14 input to the front roller conveying assembly 5.

[0053] In some embodiments, such as Figure 2 As shown, the parallel box posture adjustment device provided by the present invention further includes: a flipping fork assembly 6, which is used to flip the box material on the front roller conveying assembly 5 by 90° in the left and right direction.

[0054] Figure 10 This is a schematic diagram showing the two states and structure of the overturning fork assembly before and after overturning the box-type material in an embodiment of the present invention. Figure 10 As shown, the tilting fork assembly 6 includes a first bracket 601, a second bracket 603, a first reduction motor 604, a first gear 602, a second reduction motor 606, a second gear 608, a third bracket 607, a third gear 609, a shaft 605, and two third bearing seats 610 disposed on the lower side of the front roller conveying assembly 5, as well as a tilting bracket 611 partially located on the conveying surface of the front roller conveying assembly 5. The first bracket 603 is fixedly connected to the first bracket 601, the first geared motor 604 is fixedly connected to the second bracket 603, and the first gear 602 is fixedly connected to the end of the first geared motor 604. The second bracket 607 is fixedly connected to the first bracket 601, the second geared motor 606 is fixedly connected to the third bracket 607, and the second gear 608 is fixedly connected to the end of the second geared motor 606. Two third bearing seats 610 are fixedly connected to both ends of the first bracket 601 respectively. One end of the shaft 605 is rotatably connected to one third bearing seat 610, and the other end is rotatably connected to the other third bearing seat 610. The third gear 609 is fixedly connected to the end of the shaft 605, and the second gear 608 and the third gear 609 mesh for transmission. The tilting bracket 611 has two forks that are 90° apart, and the connecting ends of the two forks are fixedly connected to the middle position of the shaft 605.

[0055] The projection position of the fork teeth of the tilting bracket 611 in the horizontal plane corresponds to the roller gap of the front roller conveying assembly 5. The tilting fork assembly 6 is configured to: place one side of the tilting bracket 611 under the roller of the front roller conveying assembly 5 and move it left / right to the bottom of the box material to be tilted; rotate the shaft 605 to drive the tilting bracket 611 to tilt until the other side of the tilting bracket 611 is placed under the roller of the front roller conveying assembly 5. For ease of description, ... Figure 10 The two states of the tilting fork assembly are defined as 0° and 90°. When the second reduction motor 606 drives the second gear 608 to rotate, the second gear 608 meshes with the third gear 609 to rotate. The third gear 609 drives the shaft 605 and the tilting bracket 611 fixedly connected to the shaft 605 to switch between the 0° and 90° states, thus realizing the 90° tilting of the box material 14 placed on the tilting fork assembly.

[0056] In some embodiments, such as Figure 2 As shown, the parallel box posture adjustment device provided by the present invention also includes a pusher assembly 7 disposed at the front roller conveying assembly 5.

[0057] Figure 11 This is a schematic diagram of the push plate assembly and the tilting fork assembly in an embodiment of the present invention, as shown below. Figure 11 As shown, the pusher assembly 7 includes a first slide rail 703, a first rack 701, a fourth bracket 704, a fifth bracket 707, a third reduction motor 705, a fourth gear 702, and a pusher 706 located on the conveying surface of the front roller conveying assembly 5, all disposed on the lower side of the front roller conveying assembly 5. The system comprises two first slide rails 703, each with two first sliders. One of the first slide rails 703 has a first rack 701 extending along its length mounted on its inner side. The first rack 701 and the two first slide rails 703 are fixedly connected to the frame of a parallel box-type attitude adjustment device (not shown in the figure). The two ends of the fifth bracket 707 are fixedly connected to the first sliders of the two first slide rails 703. The fourth bracket 704 is fixedly connected to the fifth bracket 707, and the push plate 706 is fixedly connected to the fifth bracket 707. The third reduction motor 705 is fixedly connected to the fourth bracket 704, and the fourth gear 702 is fixedly connected to the end of the third reduction motor 705. The fourth gear 702 meshes with the first rack 701, enabling the push plate 706 to move left and right.

[0058] Furthermore, the first gear 602 meshes with the first rack 701 for transmission, and the first reduction motor 604 drives the first gear 602 to rotate. The engagement of the first gear 602 with the first rack 701 enables the left and right movement of the tilting fork assembly 6. Figure 10 and Figure 11The tipping fork assembly 6 can both rotate the box-type material 14 90° and move it left and right. Combined with... Figure 11 The tilting fork assembly 6 and the push plate assembly 7 share the first slide rail 703 and the first rack 701, which reduces the number of the first slide rail 703 and the first rack 701 and saves costs.

[0059] In this embodiment of the invention, the front roller conveyor assembly 5 can buffer multiple boxes of material 14. The pusher assembly 7 moves laterally to the right, pushing the boxed material 14 on the front roller conveyor assembly 5 to the right side. The tilting fork assembly 6 moves laterally to the left, pushing the boxed material 14 on the front roller conveyor assembly 5 to the left side. Simultaneously, the pusher assembly 7 and the tilting fork assembly 6 move laterally towards the center, clamping the multiple boxes of material 14 located on the front roller conveyor assembly 5. The beneficial effect of clamping the multiple boxes of material 14 is that it can reduce the gap between the boxes 14, thereby improving the utilization rate of the carriage space.

[0060] Figure 12 This is a schematic diagram of Embodiment 1 of the device of the present invention for adjusting boxed materials in a third posture (C). Figure 12 The posture adjustment shown is Figure 8 The third posture adjustment for the boxed material with posture B output, based on the aforementioned steps S21~S24, includes the following steps after step S24: S25: The tilting fork assembly 6 moves laterally to the left / right to prepare for the side position. At this time, one side of the tilting fork assembly 6 is located under the front roller conveyor assembly 5, and the fork teeth of the other side extend vertically upwards out of the conveying plane of the front roller conveyor assembly 5. If the box material 14 output in S24 is located to the left of the swing wheel reversing assembly 13 (the box material 14 comes from the upstream left roller conveyor assembly 10, see the description in step S24), then the overturning fork assembly 6 moves laterally to the left in advance to a position that does not obstruct the box material 14. If the box material 14 output in S24 is located to the right of the front swing wheel reversing assembly 13 (the box material 14 comes from the upstream right roller conveyor assembly 2, see the description in step S24), then the overturning fork assembly 6 moves laterally to the right in advance to a position that does not obstruct the box material 14. Figure 12 The following explanation uses the example of box material 14 output in S24 located on the left side.

[0061] S26: The front roller conveyor assembly 5 conveys the box material 14 in posture B on the left side forward to the designated position at its front end and stops.

[0062] Specifically, when the box-shaped material 14 output by the swing wheel reversing assembly 13 is located on the left side, the box-shaped material 14 is output to the upper left side of the front roller conveyor assembly 5; when the box-shaped material 14 output by the swing wheel reversing assembly 13 is located on the right side, the box-shaped material 14 is output to the upper right side of the front roller conveyor assembly 5. This is explained here with the left side as the reference point.

[0063] S27: The tilting fork assembly 6 moves laterally to the right, bringing its vertically upward forks closer to the left side of the box material 14 in posture B. Simultaneously, the tilting fork assembly 6 performs both rightward movement and leftward tilting. When the tilting fork assembly 6 flips 90° to the left, the box material 14 in posture B is transformed into the box material 14 in posture C (e.g., ...). Figure 12 The box-shaped material 14 in posture C on the front roller conveyor assembly 5 shown in the figure.

[0064] Obviously, if the box material 14 output in S24 is located to the right of the front swing wheel reversing assembly 13, then in this step S27, the overturning fork assembly 6 located on the right side moves to the left so that its vertically upward fork is close to the right side of the box material 14 in posture B. The overturning fork assembly 6 simultaneously performs two actions: moving to the left and overturning to the right.

[0065] In this embodiment, the linkage control of the lateral movement and reverse flipping movement of the overturning fork assembly 6 can not only realize the 90° flipping of the box material 14, but also flip the box material 14 to the middle position of the front roller conveying assembly 5.

[0066] In some embodiments, such as Figure 2 As shown, the parallel box attitude adjustment device provided by the present invention also includes a front blocking component 8 disposed at the front end of the front roller conveying component 5.

[0067] Figure 13 This is a schematic diagram of the front blocking assembly in an embodiment of the present invention, as shown below. Figure 13As shown, the front blocking assembly 8 includes a V-shaped bracket 802, a sixth bracket 805, a second slide rail 801, a U-shaped bracket 803, a seventh bracket 807, a lead screw stepper motor 806, and a limiting bracket 804; wherein, the V-shaped bracket 802 and the sixth bracket 805 are fixedly connected to the frame of the parallel box-type attitude adjustment device (not shown in the figure); the second slider on the second slide rail 801 is fixedly connected to the V-shaped bracket 802; the two ends of the U-shaped bracket 803 are fixedly connected to the second slide rail 801, and the middle is fixed. The top of the seventh bracket 807 is fixedly connected; the bottom of the seventh bracket 807 is fixedly connected to the end of the lead screw of the lead screw stepper motor 806, which is fixedly connected to the sixth bracket 805; the lead screw stepper motor 806 drives the U-shaped bracket 803 to rise or fall through the seventh bracket 807; the limiting bracket 804 is fixedly connected to the sixth bracket 805 and located on one side of the seventh bracket 807, and the limiting bracket 804 has a square groove in the middle to limit the vertical lifting range of the seventh bracket 807. The lead screw stepper motor 806 here can also be other devices that can achieve linear motion, such as a cylinder, a combination of gears and racks, etc.

[0068] Preferably, a layer of material with a low coefficient of friction can also be installed on the U-shaped bracket 803 to reduce the sliding friction between the U-shaped bracket 803 and the box-shaped material 14.

[0069] In this embodiment, the U-shaped bracket 803 is driven to rise by the lead screw stepper motor 806, which can raise the front blocking component 8 above the roller conveying surface of the front roller conveying component 5, thereby blocking and positioning the material conveyed by the front roller conveying component 5. This allows the material conveyed on the front roller conveying component 5 to stop moving forward when it reaches the designated position in the front section, so that the push plate component 7 and / or the tilting fork component 6 can accurately align these materials on the side to push the materials left and right.

[0070] Preferably, the structure of the rear blocking assembly 12 and Figure 13 The structure of the front blocking assembly 8 shown is the same or similar, and will not be described again here.

[0071] Figure 14 This is a schematic diagram of the structure of the dial assembly of the present invention, as shown below. Figure 14As shown, in addition to the dial gear plate 1103, the dial gear assembly 11 also includes: a third slide rail 1101, a second rack 1108, an eighth bracket 1102, a ninth bracket 1104, a guide roller 1105, a fifth gear 1106, and a fourth reduction motor 1107. The third slide rail 1101 and the second rack 1108 are fixedly connected to the frame of the parallel box-type attitude adjustment device (not shown in the figure). There are two third slide rails 1101, each with one third slider. A second rack 1108 extending along the length of one of the third slide rails is mounted on its inner side. The eighth bracket 1102 is fixedly connected to the third slider. The dial gear plate 1103 is fixedly connected to the eighth bracket 1102, and the guide roller 1105 is rotatably connected to the dial gear plate 1103. The ninth bracket 1104 is fixedly connected to the eighth bracket 1102. The fourth geared motor 1107 is fixedly connected to the ninth bracket 1104, and the fifth gear 1106 is fixedly connected to the end of the fourth geared motor 1107. The fifth gear 1106 meshes with the second rack 1108 for transmission. The fourth geared motor 1107 drives the fifth gear 1106 to rotate, so the fifth gear 1106 will move left / right relative to the second rack 1108. The ninth bracket 1104, which is fixedly connected to the fourth geared motor 1107, will be moved left / right and translated, thereby driving the eighth bracket 1102 to move left / right and translated. The eighth bracket 1102 drives the dial plate 1103 to move left / right and translated.

[0072] Figure 15 This is a schematic diagram of Embodiment 2 of the device of the present invention for adjusting the third posture C of boxed materials. The posture adjustment process is as follows: S31: Balance wheel reversing assembly 13 along Figure 7 The a direction is rotated 90° clockwise, and the drive roller 13011 is controlled to rotate forward at a speed of V4; If the rear blocking component 12 was in the raised state at the previous moment, then in S31 it is also necessary to lower the rear blocking component 12 so that it is lower than the roller conveying surface of the rear roller conveying component 1.

[0073] S32: The rear roller conveyor assembly 1 conveys the carton material 14 forward at a speed of V3. During this process, the front end of the carton material 14 in the initial posture gradually rotates to the right under the combined action of the forward speed V3, the leftward speed V4 and the guide roller 1105, until the carton material 14 rotates horizontally by 90° and becomes the carton material 14 in posture C. Obviously, in this step, under the action of speeds V3 and V4, the box-shaped material 14 in the final reversing posture C will be as follows: Figure 15 The right side of the balance wheel reversing assembly 13 is shown in the diagram.

[0074] S33: The balance wheel reversing assembly 13 controls the drive roller 13011 to reverse, so that the box material 14 in posture C is conveyed to the middle of the balance wheel reversing assembly 13.

[0075] S34: When the laser rangefinder 209 detects that the box-shaped material 14 in attitude C has been successfully collected, the balance wheel reversing assembly 13 stops operating and drives the roller 13011 to rotate rapidly back. Figure 7 The initial state is shown; S35: Control the drive roller 13011 to rotate forward, conveying the box material 14 in posture C forward to the front roller conveyor assembly 5, and then the front roller conveyor assembly 5 directly outputs the box material 14 in posture C forward.

[0076] As can be seen from the above process steps S31~S35, this second embodiment completes the adjustment from the initial attitude to attitude C during the conveying process through velocity synthesis.

[0077] Obviously, in step S31, the balance wheel reversing assembly 13 can also be used along... Figure 7 After rotating 90° clockwise in direction a, the drive roller 13011 is controlled to reverse. Then, in S33, the drive roller 13011 is controlled to rotate forward. The same applies, except that the front end of the input box material 14 is rotated to the left to become posture C. This will not be elaborated here.

[0078] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
