Description

Technical Field

[0001] The utility model relates to the technical field of a pallet dismantling machine, in particular to a pallet dismantling machine with a new structure. Background Art

[0002] Logistics sorting refers to the process by which a distribution center quickly and accurately retrieves goods from storage or other locations based on customer orders or delivery plans, sorting and centralizing them accordingly. Within the logistics sorting field, a variety of equipment for stacking and removing pallets exists, including electric and pneumatic drives, but most are constructed using welded iron frames.

[0003] The utility model patent with domestic application number 202321793050.0 discloses a floor-standing pallet dismantling and encoding machine for pallets, including a frame and an encoding device, wherein the frame is provided with a lifting device and a frame body, and the encoding device is provided with two, symmetrically arranged on both sides of the frame body; the encoding device includes a fork body and a guide rail part, and the guide rail part is installed on the frame body, and the lifting device has two output ends, each output end is connected to the middle position of the fork body part on the same side, and is used to make the fork body part rise and fall along the guide rail part. That is, the output end of the lifting device lifts the middle position of the fork body part, and is provided with the guide rail part at the same time, and the fork body part is connected to the slider of the guide rail part, so that only the middle position of the fork body part is lifted to vertically lift and fall, avoiding the synchronization problem that may occur when using a double chain, and the wear of the two ends of the fork body part is also uniform, so that the floor-standing pallet dismantling and encoding machine of the present application has low operating noise and long service life.

[0004] Most existing pallet unpacking machines have frames constructed with welded iron parts. These often cause the unpacking of pallets to vibrate and produce unusual noises when the equipment is raised or lowered, requiring lengthy maintenance or adjustments based on actual conditions. In the aforementioned utility model patent, the rack is moved forward and backward by rotating the telescopic motor, driving the two fork arms fixed at both ends to move forward and backward simultaneously to clamp the pallet. However, the rack-and-pinion transmission requires high manufacturing and installation precision, resulting in a high cost for the pallet unpacking machine. Furthermore, if there are large errors in the transmission system during operation, the rack-and-pinion transmission structure will generate significant noise. Utility Model Content

A guide rail is mounted on the guide column. Two sets of extended slides are fixedly mounted on the side of the sliding column. The sliding column and the guide rail are slidably mounted through the extended slide and the guide rail.

[0010] The horizontal tie rod is lifted by extending the auxiliary upper and lower transmission mechanisms between the slide and the guide rail, so that the lifting mechanism as a whole is transmitted up and down.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. The main spindle motor is started, and the drive shaft drives the eccentric block to rotate the eccentric shaft. During the rotation of the eccentric shaft, the limit frame and the positioning port limit it, so that it drives the fork sliding plate to reciprocate on the fork seat. The cam structure replaces the rack and pinion transmission structure. While ensuring the same load-bearing capacity, it avoids the problem of high manufacturing and installation precision of the rack and pinion itself, reduces the cost of the depalletizer, and avoids the noise problem generated by the rack and pinion transmission structure during operation. At the same time, the cam structure can reduce the risk of fork detachment caused by electronic control failure, reducing the probability of safety accidents.

[0021] 2. The shape of the positioning plate is used to clamp and fix the pallet. For pallets shorter than the positioning plate, the anti-slip support plate and elastic clips are used to clamp and support the pallet, ensuring the stability of the pallet during the unpacking process and avoiding the situation where the pallet cannot be clamped due to power failure of the electrical clamping structure, causing the pallet to fall.

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They 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 direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0033] Reference Figure 1-2 Most existing pallet unpacking machines have frames constructed with welded iron parts, which often cause the unpacking pallets to vibrate and make unusual noises when the equipment is raised or lowered, requiring lengthy maintenance or adjustments based on actual conditions. In the aforementioned utility model patent, the rack is moved forward and backward by rotating the telescopic motor in both directions, driving the two fork arms fixed at both ends to move forward and backward simultaneously to clamp the pallet. However, the rack-and-pinion transmission requires high manufacturing and installation precision, resulting in a high cost for the pallet unpacking machine. Furthermore, if there is a large error in the transmission system during operation, the rack-and-pinion transmission structure will generate a lot of noise.

[0034] In response to this problem, the applicant has improved the de-coder and developed the technical solution of the present application; a de-coder with a new structure, comprising a body frame 1, aluminum cover plates 12 welded on both sides of the body frame 1, a welded top frame 14 fixedly installed on the top of the body frame 1, two sets of guide columns 13 fixedly installed on both sides of the body frame 1, the guide columns 13 are fixedly installed on the body frame 1 through a connecting plate 131, and four sets of support seats 11 are fixedly installed on the bottom of the body frame 1. The body frame 1, the aluminum cover plates 12, the guide columns 13 and the welded top frame 14 are all made of aluminum alloy, and a frame structure with aluminum alloy as the theme is adopted, and the accuracy of the frame is greatly improved; and the structure is simple, and the assembly time is greatly shortened in the case of production, installation and on-site rectification. In the current production and operation where labor cost is the main factor, it has great competitiveness. This structural protection also adopts hollow thin sheet metal, the frame has high precision, simple installation and reduces costs.

[0035] In this embodiment, the depalletizing machine further includes a lifting mechanism 3 slidably mounted on both sides of the machine frame 1. The lifting mechanism 3 includes a sliding column 32 slidably mounted on the guide column 13 and a cross-tie rod 31 fixedly mounted between the sliding columns 32. A guide rail 132 is mounted on the guide column 13. Two sets of extended slides 33 are fixedly mounted on the side of the sliding column 32. The sliding column 32 and the guide rail 132 are slidably mounted via the extended slide 33 and the guide rail 132. The upper and lower transmission mechanisms 2 are assisted by the extended slide 33 and the guide rail 132 to lift the cross-tie rod 31, so that the lifting mechanism 3 is transmitted up and down as a whole.

[0036] The depalletizing machine also includes an upper and lower transmission mechanism 2 fixedly mounted on the top of the machine frame 1 for lifting the lifting mechanism 3. The upper and lower transmission mechanism 2 includes a driving motor 21 fixedly mounted on the welded top frame 14 and a lifting shaft 23 fixedly mounted on one side of the driving motor 21 through a bearing seat. A C-shaped gear 24 is mounted on one end of the lifting shaft 23. The lifting shaft 23 and the output end of the driving motor 21 are connected by a driving sprocket 22. A lifting chain 25 is mounted on the outer ring of the C-shaped gear 24, and the bottom of the lifting chain 25 is fixedly mounted on the horizontal tie rod 31. When the driving motor 21 is started, the driving sprocket 22 drives the lifting shaft 23 to rotate, and drives the C-shaped gear 24 to rotate, so that the lifting chain 25 pulls the horizontal tie rod 31, thereby achieving the effect of the overall upper and lower transmission of the lifting mechanism 3. Since it only targets the pallet 5, whose mass is less than or equal to 500kg, this structure adopts a single chain lifting, which is simple in structure and the selected 12A chain is sufficient to carry the load.

[0037] The depalletizing machine also includes a fork mechanism 4 slidably mounted on the lifting mechanism 3. The fork mechanism 4 includes a fork seat 41 fixedly mounted between the sliding columns 32 and located at the bottom of the transverse tie rod 31, a fork sliding plate 42 slidably mounted on the top of the fork seat 41, and a positioning plate 43 fixedly mounted at one end of the fork sliding plate 42. Two groups of fixed slides 48 are fixedly mounted on the top of the fork seat 41, and an extension opening 49 is opened on the fork seat 41 between the fixed slides 48. The bottom of the fork sliding plate 42 is slidably mounted with the fixed slide 48 through a sliding bar 46, and an anti-slip support plate 47 is fixedly mounted on the end of the sliding bar 46.

[0038] The fork slide plate 42 and fork seat 41 slide together via a fixed slide 48 and a sliding bar 46, driven by the spindle motor 6 to extend and retract the fork from the fork slide plate 42 to the pallet 5. The positioning plate 43 has a folded edge at the top, and a fixed plate 431 is fixed to its side. A spring clip 432 is secured to the fixed plate 431. The shape of the positioning plate 43 secures the pallet 5 in place. For pallets 5 shorter than the positioning plate 43, the anti-slip support plate 47 and spring clip 432 provide support and hold, ensuring the pallet's stability during unstacking.

[0039] The de-coding machine also includes a spindle motor 6 fixedly mounted on the bottom of the fork mechanism 4 and a pallet 5 for de-coding through the fork mechanism 4. The spindle motor 6 is fixedly mounted on the bottom of the fork seat 41. An eccentric block 62 is installed on the top of the spindle motor 6 through the extension opening 49. The bottom of the eccentric block 62 is fixedly connected to the output end of the spindle motor 6 through the drive shaft 61. An eccentric shaft 63 is fixedly mounted on the top of the eccentric block 62. A limit frame 45 is fixedly mounted on the bottom of the center position of the fork sliding plate 42, and a positioning opening 44 of the same size as the limit frame 45 is opened on the fork sliding plate 42. The eccentric shaft 63 passes through the positioning opening 44. When the spindle motor 6 is started, the eccentric block 62 is driven by the drive shaft 61 to rotate the eccentric shaft 63. During the rotation of the eccentric shaft 63, it is limited by the limit frame 45 and the positioning opening 44, so that it drives the fork sliding plate 42 to perform reciprocating transmission on the fork seat 41. The lifting mechanism 3 is driven by the upper and lower transmission mechanisms 2 to lift, and the fork-pulling mechanism 4 is driven by the spindle motor 6 to pull the fork, thereby achieving the destacking effect of the pallet 5.

[0040] When the present invention is in use, it is first started by the spindle motor 6, and the driving shaft 61 drives the eccentric block 62 to rotate the eccentric shaft 63. During the rotation of the eccentric shaft 63, it is limited by the limit frame 45 and the positioning port 44, so that it drives the fork sliding plate 42 to reciprocate on the fork seat 41, so that the fork sliding plate 42 and the fork seat 41 slide through the fixed slide 48 and the sliding bar 46 to clamp the pallet 5. Then it is started by the driving motor 21, and the driving sprocket 22 drives the lifting shaft 23 to rotate, and drives the C-type gear 24 to rotate, so that the lifting chain 25 pulls the cross rod 31, realizing the effect of the overall up and down transmission of the lifting mechanism 3, thereby achieving the effect of destacking the pallet 5.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
