[0003] In the prior art, there is a certain gap between the product transportation device and the packaging transportation device. Currently, a supporting plate is provided in the gap between the product transportation device and the packaging transportation device of a cartoning machine.

[0004] During the process of the product being pushed by the pushing device and entering the packaging box, the tray of the product transportation device will be driven by the product transportation device to move along the transportation direction. When pushing and cartoning, the product transportation device pauses or only moves along the transportation direction. The end of the pushing rod of the pushing device is connected with a pushing plate.

During the process of the product passing through the supporting plate, the two sides of the product are no longer limited by the side walls of the tray, and the product is prone to tipping. Moreover, during this process, the pushing plate extends out of the tray, resulting in jitter at the end of the pushing rod and the pushing plate, thus affecting the normal loading of the cartoning machine.

[0045] In the case packer in the prior art, during the process of the product being pushed by the pusher device and entering the packing box, the tray of the product transport device will be driven by the product transport device to move along the transport direction. When packing by pushing, the product transport device pauses or only maintains movement along the transport direction, and a push plate is connected to the end of the push rod of the pusher device.

[0046] After the product detaches from the tray of the product transport device, the product must pass through the supporting plate before entering the packing box. During the process of the product passing through the supporting plate, the two sides of the product are no longer limited by the side walls of the tray, and the product is prone to tipping over. Moreover, during this process, the push plate extends out of the tray, causing the end of the push rod and the push plate to vibrate, thereby affecting the normal loading of the case packer.

[0047] In order to solve the above technical problem that the product is prone to tipping over after detaching from the tray, the inventor designed this solution, and the following details of this solution will be described in detail.

[0048] Specifically, referring to Figures 1 to 6 , the product transport device that the tray can automatically approach includes: a product circulation transport mechanism, a product transport frame body 100, a product transport tray 300, and a side shift guiding structure 400.

[0049] The two sides of the product transport frame body 100 are respectively set as the packing side and the pushing side. The product transport frame body 100 is used for fixedly connecting with the frame of the case packer.

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

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

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

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

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

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

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

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

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

[0059] Naturally, the product circular transportation mechanism has a driving device. The circular drive wheel 211 of the first circular transportation component 201 is fixedly connected to the output end of the driving device of the product circular transportation mechanism to drive the product circular 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 circular drive wheels 211 of the first circular 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 circular drive wheel 211 of the first circular transportation component of another transportation component group to realize the synchronous movement of the circular drive wheels 211 of the first circular transportation components of the two transportation component groups.

[0063] The misalignment adjustment housing 221 is rotatably connected to the first connecting sleeve 223. The first connecting sleeve 223 passes through the circulating driving wheel 211 of the first circulating transportation component. Both ends of the first connecting sleeve 223 are fixedly connected to the circulating driving wheels 211 of the two second circulating transportation components of the two transportation component groups respectively, so as to realize the synchronous movement of the circulating driving wheels 211 of the second circulating transportation components of the two transportation component groups.

[0064] The misalignment adjustment worm gear 224 is fixed to the first connecting sleeve 223 by conventional fixing means such as screws.

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

[0066] One end of the misalignment adjustment worm 225 extends out of the misalignment adjustment housing 221. 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 screwing head 226 is fixed to the adjustment end. Specifically, in this embodiment, the screwing head 226 is a hexagonal block structure. In other embodiments, the screwing head 226 can also be set as a triangular block or a quadrilateral block structure, or the screwing head 226 can be set as a butterfly structure. Those skilled in the art can select the specific shape of the screwing head 226 according to actual needs.

[0068] The number of product transportation trays 300 is set to be multiple (only several trays are shown in the figure for facilitating the display of other structures). The multiple product transportation trays 300 are evenly distributed on the product circulating transportation mechanism.

[0069] And the multiple product transportation trays 300 are driven by the product circulating transportation mechanism to move along the circulating transportation path.

[0070] Specifically, in this embodiment, the product transportation tray 300 includes: a product supporting bottom 340 and product limiting side walls 350. Specifically, in this embodiment, the number of the product limiting side walls 350 is set to be two, and the two product limiting side walls 350 are respectively located on the front and rear sides of the product supporting bottom 340.

[0071] The product transportation tray 300 further includes a width adjustment frame 330, a tray sliding frame 320 and a tray driving frame 310.

[0072] The tray driving frame 310 is connected to the circulating driving strip of the first circulating transportation component 201 through a connecting piece. When the circulating driving strip of the first circulating transportation component 201 moves in a cycle, the tray driving frame 310 can be driven to move in a cycle together, so that the first circulating transportation component 201 drives the tray driving frame 310 to move along the circulating transportation path.

[0073] The tray sliding frame 320 is fixedly connected to the product supporting bottom 340 through 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.

[0074] The second cycle transportation component 202 drives the width adjusting frame 330 to move along the cycle transportation path. The tray sliding frame 320 is slidably connected to the width adjusting frame 330, and the width adjusting frame 330 can move relative to the tray sliding frame 320 along the cycle transportation path.

[0075] Specifically, in this embodiment, the width adjusting frame 330 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.

[0076] 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 fixedly connected 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.

[0077] 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.

[0078] A side shift guide member 360 is connected to the lower end of the product transportation tray 300. Specifically, the side shift guide member 360 is arranged as a roller structure, and the side shift guide member 360 is rotatably connected to the tray sliding frame 320 through a shaft structure.

[0079] When the side shift guide member 360 moves in the direction of approaching or departing from the packing side, the tray sliding frame 320 will move along with the side shift guide member 360, thereby driving the product supporting bottom 340 and the product limiting side wall 350 of the product transportation tray 300 to move in the direction of approaching or departing from the packing side.

[0080] Setting the side shift guide member 360 as a roller structure and setting the side shift guide member 360 to be rotatably connected to the product transportation tray 300 can reduce the friction between the side shift guide member 360 and other components during movement, thereby reducing the load of the driving device and being beneficial to improving the service life of the driving device.

[0081] In other embodiments, the side shift guide 360 can also be set as a block structure fixedly connected to the lower end of the product transport tray 300, and those skilled in the art can select the connection form between the side shift guide 360 and the product transport tray 300 according to actual needs.

[0082] When it is necessary to adjust the distance between the two product limiting side walls 350 of the product transport tray 300, the staff can clamp and drive the rotation of the screwing head 226 with a wrench, so as to drive the rotation of the misalignment adjustment worm gear 224, thereby driving the relative rotation of the circulating drive wheel 211 of the second circulating transport assembly and the circulating drive wheel 211 of the first circulating transport assembly, so that the circulating drive strip of the first circulating transport assembly and the circulating drive strip of the second circulating transport assembly move relative to each other.

[0083] After the staff stops driving the rotation of the screwing head 226, 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 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.

[0084] 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 at the same time, and since the sliding direction of the tray sliding frame 320 relative to the tray drive frame 310 is away from or close to the packing 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 tray sliding frame 320 moves relative to the width adjustment frame 330, so when the staff drives the rotation of the screwing head 226, the distance between the two product limiting side walls 350 will change, and when the staff does not drive the rotation of the screwing head 226, 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.

[0085] The side shift guiding structure 400 is fixedly installed on the product transportation rack 100. The side shift guiding structure 400 is provided with a general guiding track, and the side shift guiding member 360 is arranged in the general guiding track and is slidably connected with the general guiding track.

[0086] Specifically, the general 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 boxing station. The side shift guiding track 403 is located on the side of the normal guiding track 401 close to the packing side. The two inclined guiding tracks 402 are respectively arranged at the front and rear ends of the side shift guiding track 403. The ends of the side shift guiding track 403 and the ends of the normal guiding track 401 are connected through the inclined guiding tracks 402.

[0087] The product transportation rack 100 is fixedly installed with a tray supporting structure 110. The tray supporting structure 110 is arranged on the packing side and is used for supporting one end of the product transportation tray 300. When one end of the product transportation tray 300 extends a certain distance on the packing side, the tray supporting structure 110 can support the product transportation tray 300, so as to prevent one end of the product transportation tray 300 from deforming due to the gravity of the product.

[0088] The product transportation tray 300 is connected with a box supporting plate 351. Specifically, the box supporting plate 351 is fixed at one end of the product limiting side wall 350 close to the packing side.

[0089] Specifically, in this embodiment, the box supporting plate 351 and the product transportation tray 300 are adjustably connected through a strip hole and a screw. The box supporting plate 351 can be close to or far from the packing side relative to the product transportation tray 300.

[0090] Specifically, in this embodiment, one end of the box supporting plate 351 close to the packing side is connected with a guiding plate 352. The guiding plate 352 gradually inclines towards the inner side of the tray away from the pushing side.

[0091] The box supporting plate 351 can maintain the shape of the side wall of the packing box, so as to prevent the side wall of the packing box from toppling to one side and causing obstacles to the product loading.

[0092] Because the side shift guiding member 360 slides in the general guiding track, during the process of the product circulation transportation mechanism driving the product transportation tray 300 to circulate, the general guiding track will guide the side shift guiding member 360, and the inclined guiding track 402 can drive the side shift guiding member 360 to be close to or far from the packing side.

[0093] Thus, the product transportation tray 300 is far from or close to the packing side.

[0094] 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.

[0095] 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.
