Description

Technical Field

[0001] The utility model relates to the technical field of cartoning machines, in particular to a transportation device with adjustable tray width. Background Art

[0002] A cartoning machine generally includes structures such as a product transportation device, a box opening device, a packaging box transportation device, and a pushing device. The product transportation device generally includes a product circulating transportation mechanism (a structure using a chain or a synchronous belt) and a product transportation tray. The product circulating transportation mechanism drives the product transportation tray to move along the circulating transportation path. The product transportation tray includes a product supporting bottom and two product limiting side walls.

[0003] In the prior art, the two product limiting side walls are generally fixedly connected to the product supporting bottom, so that the cartoning machine can only adapt to packaging boxes of a certain width, and the applicable range is small. When the factory needs to pack different products into packaging boxes of different widths, the original cartoning machine cannot be used, and the practicability is poor.

[0004] There are also cartoning machines in the prior art with adjustable distances between the two product limiting side walls. However, the two product limiting side walls are connected to the product supporting bottom through structures such as screws and strip-shaped holes. When the distance between the two product limiting side walls needs to be adjusted, the staff needs to loosen the screws, and then drive at least one product limiting side wall to move, so that the distance between the two product limiting side walls changes until the distance between the two product limiting side walls meets the requirements. Then, the screws are tightened to fix the positions of the two product limiting side walls. Each product transportation tray needs to be operated in this way until each product transportation tray is adjusted. The adjustment is relatively inconvenient and takes a long time, which is not conducive to the rapid production of the factory. Summary of the Utility Model

DETAILED DESCRIPTION

[0042] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships mentioned in the text do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0043] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0044] In the description of the present utility model, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood to exclude the number itself, and "above", "below", "within" etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0045] In the cartoning machine in the prior art, when the product is pushed by the pushing device and enters the packaging box, the tray of the product transport device will be driven by the product transport device to move along the transport direction. When pushing the product for boxing, the product transport device pauses or only keeps moving along the transport direction. The end of the pushing rod of the pushing device is connected to a pushing plate.

[0046] After the product leaves the pallet of the product transport device, the product must pass through the support plate before entering the packaging box. During the process of the product passing through the support plate, the two sides of the product are no longer limited by the side walls of the pallet, and the product is prone to tipping over. In this process, the push plate extends out of the pallet, causing the end of the push rod and the push plate to shake, thereby affecting the normal loading of the cartoning machine.

[0047] In order to solve the technical problem that the above-mentioned products are prone to tipping over after being detached from the tray, the inventor has designed this solution, and the specific details of this solution are described in detail below.

[0048] Specifically, referring to Figures 1 to 6 , a transportation device with adjustable pallet width, comprising: a product circulation transportation mechanism, a product transportation frame 100, a product transportation pallet 300, and a side shift guiding structure 400.

[0049] Both sides of the product transportation frame 100 are respectively set as the packing side and the pushing side. The product transportation frame 100 is used for fixedly connecting with the frame of the cartoning machine.

[0050] The product circulation transportation mechanism is installed on the product transportation frame 100.

[0051] The product circulation transportation mechanism is provided with a product cartoning station, and the product cartoning station is arranged at the front end of the product circulation transportation mechanism.

[0052] The product circulation transportation mechanism is provided with a circulation transportation path.

[0053] Specifically, the product circulation transportation mechanism includes a circulation transportation component and a dislocation adjustment structure 220.

[0054] Specifically, in this embodiment, the number of the circulation transportation components is set to four. The four circulation transportation components are divided into two transportation component groups, and the two transportation component groups are arranged along the direction from the pushing side to the packing side. The two transportation component groups are respectively located on both sides of the product transportation frame 100, and the two transportation component groups move synchronously. In other embodiments, the number of the transportation component groups can also be set to one or three, etc., and the number of the circulation transportation components in each transportation component group is adjusted correspondingly. Those skilled in the art can select the number of the transportation component groups according to actual needs.

[0055] The two circulation transportation components in the same transportation component group are respectively set as the second circulation transportation component 202 and the first circulation transportation component 201. The second circulation transportation component 202 of the transportation component group is arranged on the side of the first circulation transportation component 201 in the same transportation component group close to the other transportation component group. That is, the arrangement of the four circulation transportation components is: the first circulation transportation component 201 - the second circulation transportation component 202 - the second circulation transportation component 202 - the first circulation transportation component 201.

[0056] Specifically, the circulation transportation component includes a circulation driving wheel 211 and a circulation driving strip (the circulation driving strip is not shown in the figure). The number of the circulation driving wheels 211 is set to two, and the two circulation driving wheels 211 are arranged along the front-back direction at the front end and the rear end of the product transportation frame 100.

[0057] The circulation driving strip bypasses the two circulation driving wheels 211, and the circulation driving wheels 211 are in transmission connection with the circulation driving strip.

[0058] Specifically, in this embodiment, the circulating drive bar is set as a chain structure, and the circulating drive wheel 211 is set as a sprocket structure. In other embodiments, the circulating drive bar can also be set as a synchronous belt structure, and the circulating drive wheel 211 can be set as a synchronous pulley structure. Those skilled in the art can select the structures of the circulating drive bar and the circulating drive wheel 211 according to actual needs. And the circulating transportation component of this solution should be equipped with a tensioning wheel mechanism for keeping the circulating drive bar taut. The tensioning wheel mechanism is a conventional setting in this field, and the specific structure of the tensioning wheel mechanism will not be elaborated here.

[0059] Naturally, the product circulating transportation mechanism has a driving device. The circulating drive wheel 211 of the first circulating transportation component 201 is fixedly connected to the output end of the driving device of the product circulating transportation mechanism to drive the product circulating transportation mechanism to work.

[0060] The dislocation adjustment structure 220 includes a dislocation adjustment housing 221, a first connecting sleeve 223, a dislocation adjustment worm gear 224, a first connecting shaft 222, and a dislocation adjustment worm 225.

[0061] One of the circulating drive wheels 211 of the first circulating transportation component 201 is fixedly connected to the dislocation adjustment housing 221 by screws. The dislocation adjustment housing 221 can rotate relative to the product transportation frame 100.

[0062] The first connecting shaft 222 extends in the direction from the material pushing side to the packing side. The first connecting shaft 222 is fixedly connected to the dislocation adjustment housing 221, and the first connecting shaft 222 is also fixedly connected to the circulating drive wheel 211 of the first circulating transportation component 201 of another transportation component group to realize the synchronous movement of the circulating drive wheels 211 of the first circulating transportation components 201 of the two transportation component groups.

[0063] The dislocation adjustment housing 221 is rotatably connected to the first connecting sleeve 223. The first connecting sleeve 223 passes through the circulating drive wheel 211 of the first circulating transportation component 201. The two ends of the first connecting sleeve 223 are respectively fixedly connected to the circulating drive wheels 211 of the two second circulating transportation components 202 of the two transportation component groups to realize the synchronous movement of the circulating drive wheels 211 of the two second circulating transportation components 202 of the two transportation component groups.

[0064] The dislocation adjustment worm gear 224 is fixedly connected to the first connecting sleeve 223 by conventional fixing methods such as screws.

[0065] The dislocation adjustment housing 221 is rotatably connected to the dislocation adjustment worm 225, and the dislocation adjustment worm gear 224 is in meshing transmission with the dislocation adjustment worm 225.

[0066] One end of the misalignment adjustment worm 225 extends out of the misalignment adjustment housing 221, and the end of the misalignment adjustment worm 225 that extends out of the misalignment adjustment housing 221 is set as the adjustment end.

[0067] A turning head 226 is fixed to the adjustment end. Specifically, in this embodiment, the turning head 226 is a hexagonal block structure. In other embodiments, the turning head 226 can also be set as a triangular block or a quadrilateral block structure, or the turning head 226 can be set as a butterfly structure. Those skilled in the art can select the specific shape of the turning head 226 according to actual needs.

[0068] Bearings are arranged between both ends of the misalignment adjustment worm 225 and the misalignment adjustment housing 221. By arranging bearings between the misalignment adjustment worm 225 and the misalignment adjustment housing 221, the rotation of the misalignment adjustment worm 225 can be made more relaxed, the workload of the staff can be reduced, and the service life of the misalignment adjustment worm 225 can also be extended.

[0069] The number of product transportation pallets 300 is set to be multiple (only several pallets are shown in the figure for the convenience of showing other structures), and the multiple product transportation pallets 300 are evenly distributed on the product circulating transportation mechanism.

[0070] And the multiple product transportation pallets 300 are driven by the product circulating transportation mechanism to move along the circulating transportation path.

[0071] Specifically, in this embodiment, the product transportation pallet 300 includes: a product supporting bottom 340 and product limiting side walls 350. Specifically, in this embodiment, the number of product limiting side walls 350 is set to two, and the two product limiting side walls 350 are respectively located on the front and rear sides of the product supporting bottom 340.

[0072] The product transportation pallet 300 further includes a pallet connecting frame body and a pallet driving frame 310.

[0073] Specifically, in this embodiment, the pallet connecting frame body includes a width adjustment frame 330 and a pallet sliding frame 320.

[0074] The pallet driving frame 310 is connected to the circulating driving strip of the first circulating transportation component 201 through a connecting member (the connecting member for connecting the chain and other components is a conventional structure in the art and will not be elaborated here), so that when the circulating driving strip of the first circulating transportation component 201 moves in a cycle, the pallet driving frame 310 can be driven to move in a cycle together, so that the first circulating transportation component 201 drives the pallet driving frame 310 to move along the circulating transportation path.

[0075] The tray sliding frame 320 and the product supporting bottom 340 are fixedly connected by structures such as screws. The tray driving frame 310 is slidably connected to the tray sliding frame 320, and the tray sliding frame 320 can move away from or close to the packing side relative to the tray driving frame 310.

[0076] The second cycle transportation component 202 drives the width adjustment frame 330 to move along the cycle transportation path. The tray sliding frame 320 is slidably connected to the width adjustment frame 330, and the width adjustment frame 330 can move relative to the tray sliding frame 320 along the cycle transportation path.

[0077] Specifically, in this embodiment, the tray sliding frame 320 is fixedly connected to one of the product limiting side walls 350, and the product supporting bottom 340 is fixedly connected to the other product limiting side wall 350, so that the two product limiting side walls 350 can move relative to each other, thereby adjusting the distance between the two product limiting side walls 350 to adapt to different products.

[0078] In other embodiments, the two product limiting side walls 350 can also be arranged in a form that is slidably connected to the product supporting bottom 340 and fixed to the tray sliding frame 320, but it is necessary to ensure that when adjusting the distance between the two product limiting side walls 350, the two product limiting side walls 350 move in opposite directions or the two product limiting side walls 350 move in the same direction at different speeds.

[0079] Those skilled in the art can select the connection method between the product limiting side wall 350 and the product supporting bottom 340 according to actual needs as long as the two product limiting side walls 350 can move relative to each other.

[0080] Specifically, in this embodiment, the width adjustment frame 330 includes a driving bar connecting rod 331 and a connecting sliding seat 332.

[0081] The driving bar connecting rod 331 extends in the left-right direction, and both ends of the driving bar connecting rod 331 are fixedly connected to the circulating driving bars of the two second cycle transportation components 202, so that when the second cycle transportation component 202 works, it drives the driving bar connecting rod 331 to move along the cycle transportation path.

[0082] The connecting sliding seat 332 is provided with a corner sliding strip-shaped hole 333. The length direction of the corner sliding strip-shaped hole 333 is perpendicular to the cycle transportation path, and the corner sliding strip-shaped hole 333 penetrates through the connecting sliding seat 332, so that the left and right side surfaces of the connecting sliding seat 332 are communicated. The driving bar connecting rod 331 passes through the corner sliding strip-shaped hole 333 and is slidably connected to the corner sliding strip-shaped hole 333.

[0083] Since there is a certain misalignment between the width adjustment frame 330 and the pallet connecting frame on the circular transport path, when the product transport pallet 300 moves to the corner of the circular transport component, by setting the connecting sliding seat 332 and the driving bar connecting rod 331, the driving bar connecting rod 331 will slide relative to the connecting sliding seat 332. At this time, the distance between the two product limiting side walls 350 will change, but the product transport pallet 300 does not carry any products when passing the corner of the circular transport component, so it will not affect the normal transportation of the products. After the driving connecting rod moves relative to the connecting sliding seat 332, the product transport pallet 300 can pass through the corner of the circular transport component normally, and will not cause the product transport pallet 300 to be stuck.

[0084] The lower end of the product transport tray 300 is connected with a side shift guide 360. Specifically, the side shift guide 360 ​​is configured as a roller structure, and the side shift guide 360 ​​is rotatably connected to the tray sliding frame 320 through an axle structure.

[0085] When the side shift guide 360 ​​moves toward or away from the packing side, the pallet sliding frame 320 moves along with the side shift guide 360, thereby driving the product supporting bottom 340 and the product limiting side wall 350 of the product transport pallet 300 to move toward or away from the packing side.

[0086] The side shift guide 360 ​​is configured as a roller structure, and the side shift guide 360 ​​is configured as a connection form that is relatively rotatably connected to the product transport pallet 300, which can reduce the friction between the side shift guide 360 ​​and other components when moving, thereby reducing the load of the drive device and helping to increase the service life of the drive device.

[0087] In other embodiments, the side shift guide 360 ​​may also be configured as a block structure fixedly connected to the lower end of the product transport pallet 300. Those skilled in the art may select the connection form between the side shift guide 360 ​​and the product transport pallet 300 according to actual needs.

[0088] When it is necessary to adjust the distance between the two product limiting side walls 350 of the product transport pallet 300, the staff can clamp and drive the screw head 226 to rotate by using a wrench, thereby driving the offset adjustment worm gear 224 to rotate, thereby driving the circulating drive wheel 211 of the second circulating transport component 202 and the circulating drive wheel 211 of the first circulating transport component 201 to rotate relative to each other, thereby causing the circulating drive bar of the first circulating transport component 201 and the circulating drive bar of the second circulating transport component 202 to move relative to each other.

[0089] After the operator stops driving the screwing head 226 to rotate, due to the self-locking effect of the misalignment adjustment worm gear 224 and the misalignment adjustment worm 225, the misalignment adjustment worm gear 224 and the misalignment adjustment housing 221 will not rotate relative to each other. And since the misalignment adjustment worm gear 224 is fixed to the circulating drive wheel 211 of the second circulating transport assembly 202 through the first connecting sleeve 223, and the misalignment adjustment housing 221 is fixed to the circulating drive wheel 211 of the first circulating transport assembly 201, the circulating drive wheels 211 of the first circulating transport assembly 201 and the second circulating transport assembly 202 will not move relative to each other, thus realizing the synchronous movement of the first circulating transport assembly 201 and the second circulating transport assembly 202.

[0090] Since the second circulating transport assembly 202 drives the width adjustment frame 330 to move along the circulating transport path, and the first circulating transport assembly 201 drives the tray drive frame 310 to move along the circulating transport path, the tray drive frame 310 and the width adjustment frame 330 will move along the circulating transport path simultaneously. And since the sliding direction of the tray sliding frame 320 relative to the tray drive frame 310 is away from or towards the boxing side, the tray sliding frame 320 will not generate relative movement relative to the tray drive frame 310 on the circulating transport path, and the tray sliding frame 320 will also move along the circulating transport path with the tray drive frame 310. And one of the product limiting side walls 350 is relatively fixed to the tray sliding frame 320, and the other product limiting side wall 350 moves along the circulating transport path with the width adjustment frame 330. Therefore, when the operator drives the screwing head 226 to rotate, the distance between the two product limiting side walls 350 will change, and when the operator does not drive the screwing head 226 to rotate, the distance between the two product limiting side walls 350 will not change. The distance between the two product limiting side walls 350 can be adjusted by the screwing head 226, so as to adapt to products of different specifications, thereby improving the practicability of the cartoning machine of the product transport device using this solution and the adaptability to different products.

[0091] The side shift guiding structure 400 is fixedly installed on the product transport frame body 100. The side shift guiding structure 400 is provided with a total guiding track, and the side shift guiding member 360 is arranged in the total guiding track and is slidably connected to the total guiding track.

[0092] Specifically, the total guiding track includes a normal guiding track 401, two inclined guiding tracks 402, and a side shift guiding track 403. The side shift guiding track 403 is arranged at the product cartoning station. The side shift guiding track 403 is located on the side of the normal guiding track 401 close to the boxing side. The two inclined guiding tracks 402 are respectively arranged at the front and rear ends of the side shift guiding track 403. The end of the side shift guiding track 403 and the end of the normal guiding track 401 are connected through the inclined guiding tracks 402.

[0093] The product transport frame 100 is fixedly mounted with a pallet supporting structure 110, which is arranged on the packing side and is used to support one end of the product transport pallet 300. When the product transport pallet 300 extends a certain distance from the packing side, the pallet supporting structure 110 can support the product transport pallet 300, thereby preventing one end of the product transport pallet 300 from being deformed due to the weight of the product.

[0094] The product transport pallet 300 is connected to a box supporting plate 351 . Specifically, the box supporting plate 351 is fixed to one end of the product limiting side wall 350 close to the box packing side.

[0095] Specifically, in this embodiment, the box supporting plate 351 is adjustably connected to the product transport pallet 300 through strip holes and screws, and the box supporting plate 351 can be moved closer to or farther from the packing side relative to the product transport pallet 300 .

[0096] Specifically, in this embodiment, a guide plate 352 is provided at one end of the box supporting plate 351 close to the box packing side, and the guide plate 352 is away from the material pushing side and gradually tilted toward the inner side of the tray.

[0097] The box support plate 351 can maintain the shape of the side wall of the packaging box to prevent the side wall of the packaging box from tilting to one side and causing obstruction in product loading.

[0098] Because the side-shift guide 360 ​​slides in the main guide track, the main guide track will guide the side-shift guide 360 ​​when the product circulation transport mechanism drives the product transport pallet 300 to circulate, and the inclined guide track 402 can drive the side-shift guide 360 ​​to move closer to or away from the packing side.

[0099] Thereby, the product transport pallet 300 is moved away from or close to the boxing side.

[0100] Specifically, since the lateral guide rail 403 is arranged on the side of the normal guide rail 401 close to the boxing side, and the lateral guide rail 403 is arranged at the product boxing station, the product transport tray 300 will be closer to the boxing side at the product boxing station, so that the distance between the product transport tray 300 and the external packaging box transport mechanism is reduced, the time for the product to leave the product transport tray 300 is shorter, the product is not easy to tip over, and the product can be easily loaded into the packaging box, so that the cartoning machine can maintain normal loading, thereby ensuring the quality of product boxing.

[0101] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
