[0029] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them.

[0033] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the conditions under which this application can be implemented.

[0034] like Figure 1 As shown in the figure, the embodiment of the utility model provides a palletizing device for palletizing objects such as packaging boxes, beverage packages, coal briquettes, etc. The objects have different sizes in length and width, such as rectangular packaging boxes.

[0035] like Figures 1 to 3 As shown, the palletizing device includes a base 1, an arranging device 2, a discharge device 3, and a pallet moving device 4. The arranging device 2, the discharge device 3, and the pallet moving device 4 are all connected to the base 1. The discharge device 3 and the pallet moving device 4 are located in the length direction of the base 1, and the arranging device 2 is located in the width direction of the base 1, perpendicular to the discharge device 3 and the pallet moving device 4. The arranging device 2 is flush with the discharge device 3, and the pallet moving device 4 is located below the discharge device 3.

[0036] In this embodiment, the base body 1 is in the shape of a rectangular frame, and includes two long main beams 11 and end beams 12 connecting two ends of the main beams 11 .

[0037] like Figures 4 to 6As shown, the arrangement device 2 is used to arrange multiple objects into a row in a strip shape. There are two arrangement methods: the first is to arrange the objects along the length direction, and the second is to arrange the objects along the width direction. In this embodiment, the arrangement device 2 includes a conveying mechanism 21, a rotating mechanism 22, a stopping mechanism 23, and a translation mechanism 24.

[0038] The conveying mechanism 21 is used to convey objects. The rotating mechanism 22 is located at the rear of the conveying mechanism 21 and is used to rotate the objects thereon by 90 degrees. The stopping mechanism 23 is used to stop the movement of the objects on the conveying mechanism 21 so that the objects are located at a predetermined position. The translation mechanism 24 is located outside the conveying mechanism 21 and is used to translate the objects located at the predetermined position to the unloading device 3. During operation, the conveying mechanism 21 receives the objects and conveys them forward to the rotation position. If rotation is required, the rotating mechanism 22 rotates the objects by 90 degrees and then allows the objects to continue to move forward; if rotation is not required, the rotating mechanism 22 does not move and allows the objects to move forward directly. When the objects move forward to the predetermined position and need to stop, the stopping mechanism 23 is activated to stop the objects at the predetermined position. In this embodiment, after multiple conveyances, multiple objects are stopped at different predetermined positions to form a column. Then the translation mechanism 24 translates the entire column of objects to the unloading device 3. Of course, in other embodiments, the arranging device may also adopt other structures.

[0039] In this embodiment, the conveying mechanism 21 includes a roller frame 211, a plurality of rollers 212, and a roller frame cylinder 213. The roller frame 211 is provided with a plurality of roller shafts parallel to each other. The plurality of rollers 212 are rotatably mounted on the roller shafts. The roller frame cylinder 213 is connected to and controls the roller frame 211, and is used to lift or lay the roller frame 211 flat. When lifted (such as Figure 6 ), the roller frame 211 is low in front and high in the back, and the object can slide forward by rotating the roller 212 under the action of gravity. Figure 3 ), the object can be translated onto the unloading device 3 by the translation mechanism 24. Of course, in other embodiments, the conveying mechanism may also adopt other structures.

[0040] In this embodiment, the rotating mechanism 22 includes a pallet 221, a pallet cylinder 222, and a rotating motor 223. The pallet cylinder 222 is connected to and controls the pallet 221, and is used to lift the pallet 221, so that the objects above it are separated from the roller 212 and placed on the pallet 221. The rotating motor 223 is connected to and controls the pallet 221, and is used to rotate the pallet 221, thereby rotating the objects already on the pallet 221. Of course, in other embodiments, the rotating mechanism may also adopt other structures. It is also possible not to provide a rotating mechanism, but to adopt different arrangement methods before feeding.

[0041] In this embodiment, the stop mechanism 23 includes an abutment 231, a connecting shaft 232, and a stop cylinder (not shown). The abutment 231 is connected to the stop cylinder via the connecting shaft 232, and the stop cylinder controls the up and down movement of the abutment 231. In a natural state, the abutment 231 is located below the roller 212 and does not contact the roller 212. After the stop cylinder is turned on, the abutment 231 moves up to contact the roller 212, so that the roller 212 cannot rotate. In this embodiment, there are multiple stop mechanisms 23, and the abutment 231 of each stop mechanism 23 is located at each predetermined position. When the object reaches a predetermined position, the stop cylinder controls the abutment 231 to move up, so that the roller 212 cannot rotate, and the object no longer slides forward, thereby stopping the object at the predetermined position. Of course, in other embodiments, the stop mechanism may also adopt other structures.

[0042] In this embodiment, the translation mechanism 24 includes a push plate 241 and a translation drive mechanism 242. The translation drive mechanism 242 is connected to and controls the push plate 241, and is used to push the push plate 241 to translate the multiple objects on the conveying mechanism 21 onto the unloading device 3 as a whole. In this embodiment, the translation drive mechanism 242 includes a motor and a gear rack mechanism. Of course, in other embodiments, the translation mechanism may also adopt other structures.

[0043] During operation, the roller frame is in a raised state, and the objects are transported into the arrangement device through a transmission mechanism such as a conveyor belt, and then arrive at the roller at the rear end of the conveying mechanism from the feed point, and slide forward to the top of the pallet. If rotation is required, the pallet cylinder extends to lift the pallet, so that the objects above it are separated from the roller and placed on the pallet. Then the rotating motor rotates the pallet, rotating the object 90 degrees, and then the pallet cylinder retracts to retract the pallet, so that the object falls on the roller, allowing the object to continue to move forward; if rotation is not required, the rotating mechanism does not move, allowing the object to move forward directly. When the object moves forward to the predetermined position and needs to stop, the stop cylinder controls the abutment to move up to the contact roller, so that the roller cannot rotate, and the object stays at the predetermined position. Continue the above steps, and stop multiple objects at different predetermined positions to form a column. Then the translation drive mechanism pushes the push plate to translate the entire column of objects to the unloading device.

[0044] like Figures 1 to 3 and Figure 7As shown, the unloading device 3 is used to unload objects onto the pallet 5. In this embodiment, the unloading device 3 includes a horizontal moving mechanism, a horizontal conveying mechanism 33, and a lifting mechanism 34. The horizontal moving mechanism is used to drive the horizontal conveying mechanism 33 to move horizontally, and includes a frame 31 and a frame moving mechanism 32 (in other embodiments, the horizontal moving mechanism can also adopt other structures). The frame moving mechanism 32 is connected to the frame 31, and is used to drive the frame 31 to move horizontally between the docking station (the position close to the inner side of the conveying mechanism in the arrangement device) and the palletizing station B (the position where the pallet is located). The horizontal conveying mechanism 33 is located on the frame 31. The lifting mechanism 34 is connected to the horizontal conveying mechanism 33, and is used to move the horizontal conveying mechanism 33 up and down.

[0045] During operation, the rack is driven by the rack moving mechanism to the inner side of the conveying mechanism in the arrangement device (also called the docking station), and the horizontal conveying mechanism receives multiple objects translated from the translation mechanism. Then, the rack moving mechanism drives the rack to move toward the stacking station B, and the horizontal conveying mechanism moves the objects forward horizontally, so that the objects move from one end of the horizontal conveying mechanism to the other end. The lifting mechanism drives the horizontal conveying mechanism to move up and down (due to the different heights of different layers, the stroke of the lifting mechanism will also change accordingly), and together the objects are placed in the preset unloading position (slightly higher than the pallet or the lower layer of objects in the height direction, and in the horizontal direction at the position where the objects need to be placed on the pallet). Then, the rack moves back, and the horizontal conveying mechanism continues to move the objects forward, and the moving speeds of the two are equal, so that the objects are placed in the preset unloading position. After placement, the rack moving mechanism and the lifting mechanism move to make the horizontal conveying mechanism return to the docking station, ready to receive the next batch of objects. The stacking station B of each batch of objects on the same layer is different, so that each column of objects is placed in rows on the pallet or the lower layer of objects. After one layer is coded, the next layer is coded until all layers are coded. Of course, in other embodiments, the unloading device may also adopt other structures. The speed at which the objects move on the horizontal conveying mechanism may not be equal to the moving speed of the horizontal conveying mechanism, but this method is more complicated to control the speed.

[0046] In this embodiment, the frame 31 is gantry-shaped and includes two vertically arranged columns 311 and a crossbeam 312 connecting the top ends of the columns 311 .

[0047] In this embodiment, the frame moving mechanism 32 includes a motor with a gearbox (not shown) and a first gear rack mechanism 321, the gear is mounted on the frame, and the rack is mounted on the base, so that the frame can move horizontally along the base through the motor and the gear rack mechanism. Of course, in other embodiments, the frame moving mechanism can also adopt other structures.

[0048] In the present embodiment, the horizontal conveying mechanism 33 comprises a plurality of rollers 331, two motors (not shown), and two sprocket chain mechanisms 332. A plurality of rollers 331 are rotatably mounted in parallel between two columns 311, one end of which is equipped with a sprocket 333, and the other end is not equipped with a sprocket. Specifically, the sprockets on each roller are staggered, for example, the sprockets on the odd-numbered (the 1st, 3rd, 5th, and 7th in the present embodiment) rollers are mounted on the left, and the sprockets on the even-numbered (the 2nd, 4th, 6th, and 8th in the present embodiment) rollers are mounted on the right, and the sprockets on the left and right sides are connected to the motors through chains, respectively, so that the two motors control the odd-numbered rollers and the even-numbered rollers, respectively. This staggered installation and staggered control method has a more reasonable structure, and the movement of objects is more stable. Of course, in other embodiments, the horizontal conveying mechanism may also adopt other structures.

[0049] In this embodiment, the lifting mechanism 34 includes a motor with a gearbox (not shown) and a second gear rack mechanism 341, the gear is installed on the horizontal conveying mechanism, and the rack is installed on the frame, so that the horizontal conveying mechanism can move up and down along the frame through the motor and the gear rack mechanism. Of course, in other embodiments, the lifting mechanism can also adopt other structures.

[0050] like Figure 2 , 8 As shown in Figures 9 and 10, the pallet moving device 4 is used to output the stacked objects. In the present embodiment, the pallet moving device 4 includes a supporting member 41, a pallet lifting mechanism 42, a pallet translation mechanism 43, and an empty pallet conveying mechanism 44. The supporting member 41 is in the shape of a frame, located between the two main beams 11 of the base body 1, and is used to support the pallet. The pallet lifting mechanism 42 is connected to the supporting member 41, and is used to drive the supporting member 41 to move up and down, thereby driving the pallet to move up and down. The pallet lifting mechanism 42 is installed on the pallet translation mechanism 43, and the pallet translation mechanism 43 is used to drive the pallet lifting mechanism 42 to move horizontally. The empty pallet conveying mechanism 44 is used to move the empty pallet from the receiving station A (the rear part of the base body, i.e. Figure 2 The left end position of the middle seat body) moves along the upper surface of the main beam to the stacking station B (the position of the pallet at each station is as follows Fig.10 The tray lifting mechanism 42 enables the supporting member 41 to switch between an ascending state and a descending state; in the ascending state, the tray is higher than the upper surface of the base body 1, and the tray translation mechanism 43 can drive the tray lifting mechanism 42 to move horizontally, thereby driving the tray to move horizontally through the supporting member 41; in the descending state, the tray is lower than the upper surface of the base body 1, and the tray can be placed on the upper surface of the base body 1.

[0051] During operation, at the beginning, the supporting member is located at the palletizing station B, and the pallet lifting mechanism puts the supporting member in an ascending state, and the pallet on the supporting member receives objects for palletizing. After palletizing, the pallet translation mechanism moves horizontally to translate the pallet to the finished product station C (a temporary placement position for the pallet and objects after palletizing). Then the pallet lifting mechanism causes the supporting member to sink, so that the supporting member is lower than the upper surface of the main beam, so that the pallet sinks and is placed on the upper surface of the main beam. Then the pallet translation mechanism drives the supporting member to move back to the palletizing station B, and then the pallet lifting mechanism rises to lift the empty pallet at the palletizing station B, waiting to receive objects for palletizing. In the process of the pallet translation mechanism translating the pallet to the finished product station C, the empty pallet conveying mechanism conveys the empty pallet placed at the receiving station A to the palletizing station B. Of course, in other embodiments, the pallet moving device may also adopt other structures.

[0052] In this embodiment, the tray lifting mechanism 42 includes a lifting cylinder 421 and a connecting rod mechanism 422. The connecting rod mechanism 422 is hinged to the supporting member 41. The lifting cylinder 421 is connected to the connecting rod mechanism 422, and the supporting member 41 is lifted and lowered by the connecting rod mechanism 422. Of course, in other embodiments, the tray lifting mechanism may also adopt other structures.

[0053] In this embodiment, the tray translation mechanism 43 includes a translation cylinder 431, which is fixed on the base body 1, and the rod end is connected to the tray lifting mechanism 42. Of course, in other embodiments, the tray translation mechanism can also adopt other structures.

[0054] like Figure 2 As shown, in this embodiment, the empty pallet conveying mechanism 44 includes a motor with a gearbox (not shown), a third gear rack mechanism 441 and a pallet baffle (not shown), the pallet baffle is located at the rear end of the base body, and the motor with a gearbox pushes the pallet baffle through the third gear rack mechanism 441 to move the empty pallet from the receiving station A along the upper surface of the main beam to the stacking station B. Of course, in other embodiments, the empty pallet conveying mechanism may also adopt other structures.

[0055] The following describes a palletizing method using the palletizing apparatus of this embodiment.

[0056] In this embodiment, the palletizing method includes the following three steps: arrangement operation, palletizing operation, and output operation.

[0057] The arrangement operation step is used to arrange objects, including: arranging multiple objects into strips to form a column. There are two ways of arrangement. The first is to arrange the objects along the length direction, and the second is to arrange the objects along the width direction, and then the entire column is translated to the unloading device.

[0058] Specifically, the conveying mechanism receives the object and conveys it forward to the rotating position. If rotation is required, the rotating mechanism rotates the object 90 degrees and then allows the object to continue to move forward. If rotation is not required, the rotating mechanism does not move and allows the object to move forward directly. When the object reaches the predetermined position and needs to stop, the stop mechanism is activated to stop the object at the predetermined position. Objects are continuously conveyed in, and after multiple conveyances, multiple objects are stopped at different predetermined positions to form a column. Then the translation mechanism translates the entire column of objects to the unloading device.

[0059] In this embodiment, two arrangement modes are realized by whether the rotating mechanism is in operation and whether the object is rotated 90 degrees. The same layer can have the same arrangement mode or two arrangement modes. Figures 11 to 13 As shown, in this embodiment, among the four columns of the lower layer, three columns adopt the first arrangement mode, one column adopts the second arrangement mode, and the three columns of the upper layer all adopt the second arrangement mode, thus forming a staggered stacking. Of course, in other embodiments, each layer can adopt the same arrangement mode, for example, the lower layer adopts the first arrangement mode, and the upper layer adopts the second arrangement mode.

[0060] In addition, there may be gaps between columns (if the number of objects in the two steps is equal, then there is a gap), or there may be no gaps. Figures 11 to 13 In the embodiment shown, there are gaps between the columns of the lower layer, but there are no gaps between the columns of the upper layer. In other embodiments, if the number of the two layers is inversely proportional to the length-to-width ratio of the objects, and the layers are arranged in the same manner, there may be no gaps. For example, if the length-to-width ratio is 4:3 and the number ratio is 3:4, then adjacent objects can be exactly connected without gaps.

[0061] For example, if the objects arranged in step 1 are arranged along the length direction, then the objects arranged in step 2 are arranged along the width direction. There may be gaps between the objects arranged in step 2 (if the number of objects in the two steps is equal, there is a gap), or there may be no gaps (if the number of objects in the two steps is not equal, there may be no gaps, for example, if the length-to-width ratio is 4:3 and the number ratio is 3:4, then adjacent objects can just touch each other without gaps).

[0062] The palletizing operation step is used to palletize the arranged objects and place the row of objects on the pallet. Specifically, the rack moving mechanism drives the rack to move toward the palletizing station B, the horizontal conveying mechanism moves the objects forward horizontally, so that the objects move from one end of the horizontal conveying mechanism to the other end, and the lifting mechanism drives the horizontal conveying mechanism to move up and down, and together the objects are in the preset unloading position. The rack moves back, and the horizontal conveying mechanism continues to move the objects forward. The moving speeds of the two are equal, so that the objects are placed in the preset unloading position. If the palletizing of all layers is not completed, the horizontal conveying mechanism returns to the docking station, and the unloading device continues the palletizing operation. After one layer is stacked, the next layer is stacked until all layers are stacked. If the palletizing of all layers is completed, the output step is performed.

[0063] The output operation step is used to output the stacked objects. Specifically, the supporting member is located at the stacking station B, and the pallet lifting mechanism makes the supporting member in an ascending state, and the pallet on the supporting member receives the objects for stacking. After stacking, the pallet translation mechanism moves horizontally to translate the pallet to the finished product station C (the temporary placement position of the pallet and the objects after stacking). Then the pallet lifting mechanism sinks the supporting member so that the supporting member is lower than the upper surface of the main beam, so that the pallet sinks and is placed on the upper surface of the main beam. Then the pallet translation mechanism drives the supporting member to move back to the stacking station B, and then the pallet lifting mechanism rises to lift the empty pallet of the stacking station B (the empty pallet is transported from the receiving station A by the empty pallet conveying mechanism during the process between the pallet translation mechanism moving the pallet to the finished product station C and the pallet translation mechanism driving the supporting member to move back to the stacking station B) and waits to receive the objects for stacking.

[0064] By looping the above-mentioned arrangement operation, stacking operation, and output operation steps, the arrangement, stacking, and output of the objects can be realized continuously. In other embodiments, the above-mentioned output operation step may not be adopted.

[0065] The pallet moving device and palletizing equipment of this embodiment have the following advantages:

[0066] After palletizing, adjacent layers of objects are stacked in an interlaced manner, making the stack more stable.

[0067] Simple structure and quick operation make palletizing operation highly efficient and low-cost;

[0068] The arrangement of the base, arrangement device, unloading device and tray moving device makes the whole equipment occupy a small space and easy to operate;

[0069] The stop mechanism is used to stop multiple objects at different predetermined positions, so that there are gaps between the objects, which can better meet the needs of various types of palletizing;

[0070] A rotating mechanism is set on the object conveying line, which can form different arrangements on the same conveying mechanism, saving space and facilitating operation;

[0071] A translation mechanism is set to translate the entire row of objects to the unloading device, which is more efficient and easier to operate than the single-piece grabbing method of the robot hand;

[0072] The novel unloading device, in particular, places the objects at the preset unloading position by moving the frame back while the horizontal conveying mechanism continues to move the objects forward, which is simple, efficient and reliable to operate;

[0073] The novel pallet moving device is integrated into the equipment, occupies little space and is simple and quick to operate.

[0074] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
