[0001] The utility model relates to the technical field of supporting devices, in particular to a supporting device for a gantry palletizer. Background Art

[0002] The palletizer automatically stacks cartons and packaging bags that have been loaded into containers in a certain arrangement on pallets or pallets (wood or plastic). It can stack multiple layers and then push them out to facilitate forklift transportation to the warehouse for storage. The automatic palletizer is a high-tech product integrating machinery and electronics. Medium and low-position palletizers can meet the production needs of medium and low output.

[0003] After a pile of goods is stacked on top of the pallet, the full pallet needs to be removed from the top of the supporting device, and then a new pallet needs to be placed before the stacking work can continue. This takes a lot of time and there is room for improvement. Therefore, a supporting device for a gantry palletizer is proposed. Utility Model Content

[0006] The full pallet can be driven away from its original position to avoid the transfer process affecting work efficiency, and the new pallet can replace the original position to facilitate the continuous stacking work, thereby greatly improving work efficiency. The motor between the two fixed frames is started, and the motor shaft drives the gear to rotate, the gear drives the gear ring to rotate, and the gear ring drives the support frame to rotate on the top of the bottom plate. The pallet full of goods will leave the external palletizer with the support frame, and the new pallet will replace the original pallet under the palletizer, so that the stacking work can continue, and the pallet full of goods will have enough time to be moved away.

[0007] As a further preferred embodiment of the present technical solution, the limit assembly includes a limit groove opened on the top outer wall of the supporting bracket, two limit plates are slidably connected in the limit groove, the inner walls on both sides of the limit groove are rotatably connected to the same bidirectional screw, the two limit plates are respectively threadedly sleeved on the threads at both ends of the bidirectional screw, the circumferential outer wall of the supporting bracket is rotatably connected to a turntable, and the turntable and one end of the bidirectional screw are coaxially fixed.

[0008] It can play the role of positioning the pallet, thereby ensuring that the goods can accurately fall on the top of the pallet, avoiding the problem of instability of the goods, and can also adjust the position of the two limit plates at will according to the model of the pallet. By driving one end of the two-way screw rod to rotate through the turntable, the two limit plates restricted by the limit groove can be driven by the two-way screw rod to move toward each other. At this time, the two limit plates can just limit the position of the pallet.

[0013] The utility model provides a supporting device for a gantry palletizer, which has the following beneficial effects:

[0014] (1) The utility model is capable of driving a full pallet away from its original position by setting a driving assembly, thus avoiding the transfer process from affecting work efficiency, and allowing a new pallet to replace the original position, so that the stacking work can continue, thereby greatly improving work efficiency.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] The utility model provides a technical solution: Figure 2 and Figure 3 As shown, in this embodiment, a supporting device for a gantry palletizer includes a base plate 1, characterized in that: a top outer wall of the base plate 1 is rotatably connected to a supporting frame 2, a same driving assembly 3 is installed between the base plate 1 and the supporting frame 2, the driving assembly 3 includes a gear ring 301 fixedly sleeved at the bottom of the circumferential outer wall of the supporting frame 2, two symmetrically arranged fixing frames 302 are fixedly connected to one side of the top outer wall of the base plate 1, a same motor 303 is fixedly installed between the two fixing frames 302, a gear 304 is coaxially fixed to the rotating shaft of the motor 303, the gear 304 is meshed with the gear ring 301, three limit assemblies 4 are installed on the top of the supporting frame 2, and the three limit assemblies 4 are distributed at equal distances.

[0023] Start the motor 303 between the two fixed frames 302, the shaft of the motor 303 drives the gear 304 to rotate, the gear 304 drives the gear ring 301 to rotate, the gear ring 301 drives the support frame 2 to rotate on the top of the bottom plate 1, the pallet full of goods will leave the bottom of the external palletizer with the support frame 2, the new pallet will replace the original pallet under the palletizer, the palletizing work can continue, and the pallet full of goods will have enough time to be moved away, which is conducive to improving work efficiency.

[0024] like Figure 2 and Figure 4 As shown, the limit assembly 4 includes a limit groove 401 opened on the top outer wall of the supporting frame 2, and two limit plates 402 are slidably connected in the limit groove 401. The inner walls on both sides of the limit groove 401 are rotatably connected to the same bidirectional screw rod 403. The two limit plates 402 are respectively threadedly sleeved on the threads at both ends of the bidirectional screw rod 403. The circumferential outer wall of the supporting frame 2 is rotatably connected to a turntable 404, and the turntable 404 and one end of the bidirectional screw rod 403 are coaxially fixed.

[0025] The two limiting plates 402 are fixedly connected with a same telescopic rod 405, which ensures the normal movement of the limiting plates 402 and also serves the purpose of limiting the tray.

[0026] It can play the role of positioning the pallet, thereby ensuring that the goods can accurately fall on the top of the pallet, avoiding the problem of instability of the goods, and can also adjust the positions of the two limit plates 402 at will according to the model of the pallet. By driving one end of the two-way screw rod 403 to rotate through the turntable 404, the two limit plates 402 restricted by the limit groove 401 can be driven by the two-way screw rod 403 to move toward each other. At this time, the two limit plates 402 can just limit the position of the pallet.

[0027] like Figure 1 and Figure 2 As shown, a tilted plate is disposed at one end of the plurality of limit plates 402 that are away from each other, and the two tilted plates are symmetrically disposed, so that the placement process of the tray is easier and helps to increase the fault tolerance of the placement process.

[0028] like Figure 1 and Figure 2 As shown, the transmission ratio between the gear ring 301 and the gear 304 is much smaller than one, which can reduce the load on the motor 303 during the driving process.

[0030] The utility model provides a supporting device for a gantry palletizer, and the specific working principle is as follows:

[0031] When the device is working, the external palletizer places the goods on the top of one of the pallets in turn. After the stacking is completed, the motor 303 between the two fixed frames 302 is started, and the rotating shaft of the motor 303 drives the gear 304 to rotate, and the gear 304 drives the gear ring 301 to rotate, and the gear ring 301 drives the bracket 2 to rotate on the top of the bottom plate 1. The pallet full of goods will leave the bottom of the external palletizer along with the bracket 2, and the new pallet will replace the original pallet under the palletizer, and the palletizing work can be continued. The pallet full of goods also has enough time to be moved away, which is conducive to improving work efficiency. The limiting component 4 can play the role of positioning the pallet, so as to ensure that the goods can accurately fall on the top of the pallet to avoid the problem of instability of the goods, and the position of the two limiting plates 402 can be adjusted at will according to the model of the pallet. The turntable 404 drives one end of the bidirectional screw rod 403 to rotate, and the two limiting plates 402 limited by the limiting groove 401 can be driven by the bidirectional screw rod 403 to move toward each other. At this time, the two limiting plates 402 can just limit the position of the pallet.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
