Description

Novel automatic bottle unloading device for can bottles

Technical Field

The invention belongs to the technical field of unstacking equipment, and particularly relates to a novel automatic bottle unloading device for empty fruit can bottles.

Background

The stacked empty glass bottles are required to be used in the production process of the bottled cans, and the stacked empty glass bottles can be pushed out layer by layer after being placed into an automatic unstacker. With the continuous research and development of new products, the appearance of the glass bottle is not the traditional standard cylinder shape, but becomes new and different, which obviously stimulates the purchasing desire of people and has better market prospect. However, I find that the existing unstacker has two main defects in the production process:

firstly, because the empty bottles are all outsourcing goods, the empty bottles of pile up neatly take place wholly crooked easily in links such as packing, transportation, loading and unloading, bale breaking, especially the bottle that bottom surface supported area is little and the shape is unique, send the probability of whole slope great, be difficult to sometimes carry and get into the unstacker, need the manual work to unload crooked empty bottles one by one, efficiency is comparatively slow. Moreover, certain gap allowance can be left between the inner walls of the two sides of the unstacker and the bottles so as to adapt to the bottles with different specifications, and after the inclined stacked empty bottles are placed into the unstacker, when the empty bottle at the topmost layer is transversely pushed, the whole inclined empty bottles are easily caused to be more serious, even topple and break. At present, the side limiting plate is used for supporting, so that the effect of supporting and limiting the periphery of an empty bottle is achieved, however, the mode requires that workers move back and forth on two opposite sides of the unstacker to adjust respectively, the workers need to repeatedly observe the inclined states of the two sides, the operation is inconvenient, and the error is easy to occur.

And secondly, the unstacked trays are output through a conveying belt, namely, the unstacked trays and the unstacked trays are synchronously conveyed in the same direction, and the output trays are manually moved out to be stacked and then are conveyed away by a forklift. In addition, no matter wooden tray or plastics tray, its self all has certain weight, and the tray all upwards stacks to fall in addition, along with stacking the increase of falling the height, and the process of placing is also very inconvenient, and workman's intensity of labour is big, stacks to fall also inegularly, and it is great to easily empty danger when placing and transporting.

the key points are that the top end and one side of the destacking bin are respectively provided with a supporting and limiting mechanism and a tray stacking mechanism;

the supporting and limiting mechanism comprises a bidirectional screw rod crossing the width direction of the top end of the destacking bin; two ends of the bidirectional screw rod are respectively provided with a sliding sleeve which is in threaded connection with the bidirectional screw rod and moves oppositely and relatively, and the bottom end of the sliding sleeve is respectively fixedly provided with a side aligning plate which is higher than the material pushing plate in height; the sliding sleeve drives the side alignment plates to move towards each other or move away from each other in a reverse direction under the transmission of the bidirectional screw rod;

the tray stacking mechanism comprises stacking oil cylinders arranged between the horizontal conveyor belts and lifting frames symmetrically arranged on two sides of the horizontal conveyor belts; the stacking oil cylinder is used for lifting the empty tray, and the height of the stacking oil cylinder during contraction is lower than that of the horizontal conveyor belt;

the lifting frames are arranged in a bilateral symmetry mode by taking the stacking oil cylinders as centers, and the bottom ends of the lifting frames are mutually and rotatably connected with the rotating shaft through torsion springs; a connecting rod is fixedly arranged on the rotating shaft, and the other end of the connecting rod is connected with the driving end of the driving part through a limiting slotted hole; the top of lifting frame is equipped with respectively and is the lifting plate of subtending setting each other, just the bottom of lifting plate is equipped with the toper deflector respectively.

Further, the tray stacking mechanism further comprises a side regulating plate arranged along the advancing direction of the horizontal conveyor belt; the side regulating plates are symmetrically arranged on the front side and the rear side of the stacking oil cylinder and are connected with the equipment frame through distance adjusting screw rods.

Further, the bottom ends of the side regulating plates are respectively of a reverse outward expansion type structure.

Further, the lifting plate and the horizontal conveyor belt are separated by the height distance of at least one tray.

Example one

Referring to fig. 1 to 6, the invention relates to a novel automatic bottle unloading device for canned bottles, which comprises an unloading bin 1 with a lifting oil cylinder 4 at the bottom end; the bottom of the destacking bin 1 is provided with a horizontal conveying belt 2 driven by a conveying motor; the top end of the destacking bin 1 is provided with a material pushing plate 5 which moves in a horizontal stroke through a driving part;

the top end and one side of the destacking bin 1 are respectively provided with a supporting and limiting mechanism 6 and a tray stacking mechanism 7;

the supporting and limiting mechanism 6 comprises a bidirectional screw rod 603 stretching across the width direction of the top end of the destacking bin 1; two ends of the bidirectional screw 603 are respectively provided with a sliding sleeve 604 which is threaded with the bidirectional screw and moves oppositely and relatively, and the bottom end of the sliding sleeve 604 is respectively fixedly provided with a side alignment plate 605 which is higher than the material pushing plate 5; the sliding sleeve 604 drives the side alignment plate 605 to move toward each other or away from each other in opposite directions under the transmission of the bidirectional screw 603;

the tray stacking mechanism 7 comprises a stacking oil cylinder 701 arranged between the horizontal conveyor belts 2 and lifting frames 707 symmetrically arranged at two sides of the horizontal conveyor belts 2; the stacking oil cylinder 701 is used for lifting the empty tray 3, and the height of the stacking oil cylinder 701 when the stacking oil cylinder 701 is contracted is lower than that of the horizontal conveyor belt 2;

the lifting frame 707 is arranged symmetrically left and right around the stacking oil cylinder 701, and the bottom end of the lifting frame 707 is rotationally connected with the rotating shaft 705 through a torsion spring 706; a connecting rod 704 is fixedly arranged on the rotating shaft 705, and the other end of the connecting rod 704 is connected with the driving end of the driving part 702 through a limiting slot 703; the top ends of the lifting frames 707 are respectively provided with lifting plates 709 which are arranged oppositely, and the bottoms of the lifting plates 709 are respectively provided with a conical guide plate 708.

Example two

Referring to fig. 1, the tray stacking mechanism 7 further includes a side regulation plate 710 provided along the traveling direction of the horizontal conveyor belt; the side regulating plates 710 are symmetrically arranged on the front side and the rear side of the stacking oil cylinder 701 and are connected with an equipment frame through distance adjusting screws. The bottom ends of the side regulating plates 710 are respectively of a reverse outward expansion type structure. The structure can play a role in orderly alignment in the front-back direction, and the outward-expanding structure at the bottom end is convenient for the oblique tray to smoothly access and return.

The lifting plate 709 is spaced apart from the horizontal conveyor 2 by at least the height distance of the tray 3 with reference to fig. 3 to 6. The height distance is convenient for the entering of the following empty tray, and the lifting and stacking from bottom to top are realized.

Referring to fig. 2, the inner opposite surfaces of the side aligning plates 605 have an inclined structure with a wide top and a narrow bottom, respectively. Through the structure, smooth guiding and returning of the topmost empty bottle can be facilitated, and the phenomenon that the empty bottle is clamped and cannot be matched due to overlarge inclination angle is prevented.

With reference to fig. 1, the stripper plates 5 are inclined away from the depalletizing bin 1. When the empty bottle of pile up neatly takes place the fore-and-aft direction slope, can aim at the scraping wings with the incline direction, along with continuous lifting, utilize the scraping wings of slope to serve the direction to the empty bottle of top layer can, prevent that the too big phenomenon that causes to block unable matching station of inclination.

The driving member 702 is a driving cylinder.

The working principle is as follows:

referring to fig. 1 and 2, the side aligning plates are used for aligning inclined stacking empty bottles, namely, the empty bottles at the topmost layer can be gradually aligned after being limited by the side aligning plates at the two sides, so that the material pushing plates can be conveniently and smoothly unstacked. The hand-operated lever 601 is used for rotating the bidirectional screw 603, the sliding sleeve 604 moves in an opposite direction in a close manner or in a reverse direction away from the bidirectional screw 603 under the action of the guide 602, the operation of workers is simple and convenient, and the hand-operated lever 601 can be adjusted while standing on the operation platform for observation.

Referring to fig. 3 to 5, the unstacked empty pallet stops when being conveyed to the position right above the stacking cylinder 710, the automatic lifting of the stacking cylinder is controlled by a corresponding travel switch or an inductive switch, and when the first empty pallet is lifted, the conical guide plate at the lower part of the lifting plate is touched by the top of the pallet and continuously expands towards two sides, so that the lifting of the stacking cylinder is prevented from being influenced. When the tray is lifted to a certain height, the conical guide plates are separated from contact and inserted into the fork holes of the tray under the elastic reset of the torsion springs, so that the aim of suspending and lifting the tray is fulfilled. At this time, the stacking oil cylinder contracts to wait for the arrival of a second empty tray.

Referring to fig. 6, after the empty trays are stacked, the stacking oil cylinders lift to lift and support the empty trays, and the lifting frame is not pressed by the trays any more. At the moment, the driving part drives the lifting frame to expand outwards through the connecting rod and the rotating shaft, so that the lifting plate is separated from the fork hole of the tray, and the forklift is inserted into the tray at the bottommost layer and then unloaded.

The lifting height of the stacking oil cylinder is the set height distance of one tray, so that the tray is conveniently jacked up from bottom to top. The lifting plate plays a role in elastic insertion under the action of the torsion spring, and meanwhile, in order to prevent the deformation caused by heavy weight and crush, the equipment frame is also provided with a positioning seat playing a role in blocking, and the positioning seat is arranged on the inner side of the lifting frame. The torsional spring can play good limiting action, and the lifting frame can keep a normal lifting posture. When the lifting frame is forced to expand, powerful elastic reset can be provided for the lifting frame, and the lifting frame is similar to a one-way buckle principle, so that manual operation is not needed. The side regulation plate can be used for regulating the front direction and the rear direction of the empty tray, and is convenient to unload.
