Description

Technical Field

[0001] The utility model relates to the technical field of metal can stacking and packaging systems, in particular to a metal can limiting mechanism which is convenient for replacement. Background Art

[0002] When stacking metal cans, it is necessary to place all the metal cans in a layer on the pallet at one time through the clamping mechanism, and then lay felt paper. After the pallet is lowered, the metal cans are stacked again until the layer height is met and the stacking is completed and the pallet is replaced. It can be seen from the above process that the laying of felt paper takes time. During this time, the metal cans need to be continuously transported to the designated position and stopped in a fixed state so that the subsequent clamping mechanism does not need to make additional changes to improve efficiency. Since the metal cans are not necessarily arranged horizontally and vertically during transportation, the above-mentioned limiting mechanism also needs to be changed according to the needs, and no matter how it is changed, it is necessary to avoid affecting the stacking action of the metal cans. Utility Model Content

[0003] In order to solve the problem that the above conventional limiting mechanism is a flat plate structure and cannot be applied to some metal can transportation lines, the utility model provides a metal can limiting mechanism that is easy to replace.

[0004] The technical solution of this utility model is as follows:

[0005] A metal can limiter mechanism that is easy to replace is arranged at one end of a lifting and transporting mechanism close to a metal can conveyor belt, and comprises a transverse support beam fixed to the lifting and transporting mechanism, a guide member is arranged above the transverse support beam, and a horizontal plate is arranged on the guide member, and the horizontal plate and the metal can conveyor belt are located at the same horizontal plane;

[0006] A lifting pallet that moves vertically along the guide member is arranged between the horizontal plate and the transverse support beam. The upper surface of the lifting pallet is horizontal, and a plurality of limiting columns are arranged in a direction perpendicular to the transport direction of the metal can conveyor belt. The horizontal plate is provided with clearance holes at the position of the limiting columns, and the top ends of the limiting columns can penetrate the horizontal plate and extend outward.

[0007] By setting a horizontal plate, it can act as a support to ensure the transportation of metal cans during stacking. Then, by setting a clearance hole, the limit column below that can be raised and lowered can be extended normally, so as to block the subsequent metal cans. By switching the limit column, the metal can can be limited and the stacking can be avoided. In the above structure, the arrangement of the limit columns can be freely changed according to needs, so the degree of freedom is relatively high.

[0008] The guide member is designed in such a way that two guide members are arranged at both ends of the transverse support beam, and include a U-shaped support plate and a vertically arranged column, and the lifting support plate is penetrated and limited by the column.

[0009] The lifting and lowering of the lifting tray is achieved in that the lifting and lowering support plate includes a horizontally arranged fixed plate, the limiting column is detachably arranged on the fixed plate, and the fixed plate is connected to the horizontal support beam through a telescoping device.

[0010] In order to adapt the can conveyor belt to the height of the metal cans, the height of the transverse support beam in the vertical direction can be adjusted.

[0011] In order to change the limiting position according to the position of the metal can, the guide member can move in the horizontal direction relative to the transverse support beam, and the moving direction is perpendicular to the transport direction of the metal can conveyor belt.

[0012] To ensure that the stacking of metal cans is not affected after the limit column is lowered, the lowest horizontal plane that the top end of the limit column can reach is lower than the horizontal plane where the upper surface of the horizontal plate is located.

[0013] The above-mentioned limiting columns are arranged in such a manner that two adjacent limiting columns are arranged at intervals in a direction perpendicular to the conveying direction of the metal can conveyor belt, and two limit columns form a group, so as to limit the same metal can at the same time, and are arranged symmetrically about the metal can. Since a single limiting column abuts against a metal can, which may cause the metal can to be easily displaced, two limiting columns can abut against a cylindrical metal can to ensure that its position is fixed.

[0014] The above-mentioned limiting columns are arranged in such a manner that two adjacent groups of limiting columns have the same spacing in a direction perpendicular to the transport direction of the metal can conveyor belt.

[0015] In order to be suitable for staggered metal cans, two adjacent groups of limiting columns are staggered in the transport direction of the metal can conveyor belt.

[0016] As a preferred solution, the top end of the limiting column is hemispherical, and the positioning hole is in close contact with the side surface of the limiting column in the circumferential direction.

[0017] The beneficial effects of the utility model are as follows: the utility model is a metal can limiting mechanism which is easy to replace, which is different from the existing flat plate limiting structure, and can be supported by limiting positions through freely arranged limiting columns, and the above-mentioned limiting columns are arranged in groups of two, which can avoid the displacement of metal cans during conveyor belt transportation, and the lifting design of the limiting columns can achieve the stacking of metal cans through horizontal displacement without raising the height of the metal cans, which is more efficient. In this process, the horizontal plate with the clearance hole can act as an intermediate support to prevent the metal cans from falling. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] like Figure 2-5 A metal can limiter mechanism that is easy to replace is shown in FIG. Figure 1 As shown, it is arranged at one end of the lifting and transporting mechanism 1 close to the metal can conveyor belt, and is used to block the metal cans and ensure that the arrangement of the metal cans is fixed after they collide with the limiting mechanism 2, thereby ensuring that the stacking mechanism can clamp and stack them in a fixed manner each time to improve efficiency and avoid operations that require position adjustment. The above-mentioned limiting mechanism 2 includes a transverse support beam 21 fixed to the lifting and transporting mechanism 1, and a guide member 22 is arranged above the transverse support beam 21, and a horizontal plate 23 is arranged on the guide member 22. The horizontal plate 23 and the metal can conveyor belt are located in the same horizontal plane, and the guide member 22 can not only support the horizontal plate 23, but also can be used for guiding, and the guide member 22 and the horizontal plate 23 are detachably connected by bolts. After the specifications of the metal cans change, the horizontal plate 23 can be replaced as needed to improve the applicability of the system.

[0028] like Figure 2As shown, the guide member 22 is designed in such a way that two guide members 22 are arranged at both ends of the transverse support beam 21, and include a U-shaped support plate 221 and a vertically arranged column 222, the lifting support plate 24 is penetrated and limited by the column 222, the opening of the U-shaped support plate 221 is arranged horizontally, and the column 222 is arranged between the two transverse plates and used for guiding, which is convenient for disassembly, and the fixed position of the lower end of the U-shaped support plate 221 and the transverse support beam 21 can be adjusted. After the waist-shaped hole is arranged, the displacement adjustment can be carried out according to the actual use situation to ensure the use effect. In this way, the horizontal plate 23 and the lifting tray 24 can be adjusted at the same time to ensure the synchronization of the two to avoid affecting the use.

[0029] like Figure 1-3 As shown, a lifting plate 24 that moves vertically along the guide member 22 is provided between the horizontal plate 23 and the transverse support beam 21, and the moving track of the lifting plate 24 is located between the horizontal plate 23 and the transverse support beam 21 to adjust the position according to demand. The upper surface of the lifting plate 24 is horizontal, and a plurality of limiting columns 25 are arranged in a direction perpendicular to the transport direction of the metal can conveyor belt. The purpose of providing a plurality of limiting columns 25 is to block the metal cans to prevent the metal cans from moving out of the original track range after transportation, and in order to achieve the blocking effect, the horizontal plate 23 is provided with a clearance hole at the position of the limiting column 25, and the top end of the limiting column 25 can penetrate the horizontal plate 23 and extend outward to ensure that the metal can can be blocked from above the horizontal plate 23 through which it is to pass.

[0030] On the basis of the above structure, the lifting tray is lifted in the following manner: the lifting support plate 24 includes a horizontally arranged fixed plate 241, the limit column 25 is detachably arranged on the fixed plate 241, and the fixed plate 241 is connected to the horizontal support beam 21 through a telescope 242. The telescope 242 can be pneumatically driven or electrically driven, but since the pneumatic reaction speed is faster, pneumatic drive can be generally used for efficiency considerations, and the output direction of the telescope 242 must be vertical, and the setting position is preferably in the center, and other considerations do not need to be made.

[0031] The above structure can achieve this. By setting the horizontal plate 23, it can act as a support to ensure the transportation of metal cans during stacking. Then, by setting the clearance holes, the limiting columns 25 that can be raised and lowered below can be extended normally, so as to block the subsequent metal cans. By switching the limiting columns 25, the metal cans can be limited and the stacking can be avoided. In the above structure, the arrangement of the limiting columns 25 can be freely changed according to needs, so the degree of freedom is relatively high.

[0032] In addition to the above structure, in order to adjust the height of the metal can conveyor belt adaptively, the height of the horizontal support beam 21 in the vertical direction can be adjusted. Through this arrangement, the structure can be fine-tuned according to the actual use of the metal can conveyor belt, and by moving the horizontal support beam 21, the height of other structural parts can be adjusted synchronously without the need for other adjustment operations.

[0033] Afterwards, further, in order to change the limiting position according to the position of the metal can, the guide member 22 can move in the horizontal direction relative to the transverse support beam 21, and the moving direction is perpendicular to the transport direction of the metal can conveyor belt.

[0034] At the same time, in order to ensure that the stacking of the metal cans will not be affected after the limiting column 25 is lowered, the lowest horizontal plane that the top of the limiting column 25 can reach is lower than the horizontal plane of the upper surface of the horizontal plate 23. During the translation of the metal can, it will not be blocked and the metal can can be prevented from tipping over here.

[0035] Finally, and most importantly, since the metal can is a cylindrical structure, in order to avoid the misalignment of the metal can, the above-mentioned limiting columns 25 are arranged in such a way that two adjacent limiting columns 25 are arranged at intervals in a direction perpendicular to the transport direction of the metal can conveyor belt, and two limit columns 25 form a group, so as to limit the same metal can at the same time, and are arranged symmetrically about the metal can. Since a single limiting column 25 contacts the metal can, which may cause the metal can to be easily displaced, two limiting columns 25 can be used to contact the cylindrical metal can to ensure that its position is fixed.

[0036] like Figure 4 , 5 As shown, the arrangement of the above-mentioned limiting columns 25 is that the spacing between two adjacent groups of limiting columns 25 in the direction perpendicular to the conveying direction of the metal can conveyor belt is the same. In order to be suitable for staggered metal cans, the two adjacent groups of limiting columns 25 are staggered in the conveying direction of the metal can conveyor belt.

[0037] Due to the design of guiding the limiting column 25, the top of the limiting column 25 is hemispherical, and the positioning hole is circumferentially close to the side of the limiting column 25. It can ensure that during the lifting process, the limiting column 25 is always straight up and down.
