Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a bottle unboxing method for taking out empty bottles from packaging boxes conveyed on a conveyor and transferring them to a filling line, and a bottle unboxing device used to carry out the method. Regarding.

Conventionally, the method of unboxing bottles was to use a hanging method that attached fingers that were placed directly above multiple bottles stored in parallel in a packaging box and narrowed the distance between them by operating an air cylinder.
After setting up the lifting device and opening the top lid of the packaging box, lower the lifting device, hold the bottle neck with its fingers, lift the bottle, remove it from the packaging box, and then transport it horizontally. Generally, those mounted on a conveyor are used,
This method of unboxing cannot be used for bottles with thick necks because the fingers of adjacent hanging tools interfere with each other, and if the bottle is misaligned, the bottle cannot be used. There was a risk that the bottle might fall during transportation if the neck was not gripped and the bottle was taken out incorrectly, or if the bottle was gripped incorrectly.

The present invention has been completed in order to avoid the problems mentioned above, and it is possible to reliably take a bottle out of a packaging box and transfer it to a conveyor without being limited by the shape of the bottle.

Five mounting members 73 are mounted at equal intervals. The rearmost mounting member 7 of the slat conveyor D in the conveyance direction
As shown in FIG. 4, an air cylinder 76 is fixed horizontally to a bracket 75 (10) fixed to the upper surface of the rear end of the other four mounting members 73 except for 3, and an air cylinder 76 is fixed to the front surface of the bracket 75. The tip of the piston rod 77 is fixed to a rack 79 that is fitted in a sliding groove 78 formed in the mounting member 73 so as to be able to freely slide back and forth. shaft 80 supported by
A pinion 81 fixed to the piston rod 77 meshes with the rack 79, and a flat stopper 83 is fixed to the tip of an arm 82 fixed to the shaft 80.
As the attachment member 73 contracts or expands, it swings between a position where it protrudes forward, as shown by the solid line in FIG. 4, and a position where it retracts upward, as shown by the chain line in the same figure. There is. Furthermore, a fixed stopper 84 that projects forward is attached to the front surface of the rearmost mounting member 73. Furthermore, a corresponding pressing plate 85 is fixed to the front surface of each of the five mounting members 73 so that the projections and recesses engage with each other.

This embodiment has the following second configuration, and its operation will be explained next.

While the packaging box a is being transported to the left side of FIG. 2 by being pushed by the feed rod 8 on the sliding plate 1 by the circular running of the pair of left and right endless chains 7, first,
The lid of the packaging box a is opened in the front, rear, left and right directions by a lid opening device (not shown) and transported forward, and the feed rod 8 stops running at the position where it hits the first stopper 9a protruding from the gap between the sliding plates 10. When the four compartments in the front row of the packaging box a stop at positions directly below the window holes 11 of the substrate 10, a pair of left and right endless chains 22 provided on the lower surface of the sliding plate 1 are driven, and the elevating body 23 is raised. Along with this, the protruding L rods 26 fixed to the upper surface of the supporting member 25 rise respectively, and their tips pass through the through hole 27 of the sliding plate l and the through hole d of the packaging box a. Poke the bottom of the bottle.

At this time, each support plate 38 is in a vertical position opening the opening 33 as shown by the chain line in FIG. , the partition plate 48 and the support member 34 passed between the support member 34
The horizontal plate 32 is guided by the corresponding surface 47 and the support plate 38.
It passes through the opening 33 formed between them and is pushed up to its upper surface. Then, the piston rod 44 of the air cylinder 43, which is swingably attached to the base plate 10'', extends as shown by the solid line in FIG. It is swung to a horizontal position and fixed, supporting the bottom of 6 bottles 1). Here, since the four parts 37 are formed on the tip edge of each support plate 38, even when the uplifting rod 26 is pushed up, the rocking movement of the support plate 38 is not hindered, and all six bottles When the bottom surfaces of the chain 26 are supported by the pair of front and rear support plates 38, the endless chain 22 is driven in the opposite direction, and the projecting rod 26 returns to its original lower position.

Next, when the piston rod 61 of the air cylinder 60 fixed on the mounting base 56 is contracted as shown by the chain line in FIG. The small gear 64 that meshes with it rotates counterclockwise in FIG. 2, and the large gear 7o that is fixed on the same axis as the small gear 64 also rotates counterclockwise, and the rack 6 (13) that meshes with it rotates counterclockwise. 9 moves to the left side in FIG. 2, both racks 6
The shaft 7 is spanned between receivers 710 fixed to the lower surface of 9.
The mounting member 73 fixed to 2 moves forward in the direction of the slat conveyor D. As the mounting member 73 moves forward, the suppression plate 85 attached to the front of the mounting member 73 moves 6 bottles 1
] In order to press the rear surface, the six bottles slide on the horizontal transfer surface C formed by the support plate 38 and the front horizontal plate 32, and are simultaneously transferred onto the slat conveyor D in front of it.

At this time, the stopper 83 provided on each mounting member 73
Since it is in the protruding position shown by the solid line in the figure, the six bottles transferred to the slat conveyor D''2 are prevented from traveling by the stopper 83 protruding forward in the conveyance direction.

First, the air cylinder 7 of the frontmost mounting member 73
The piston rod 77 of No. 6 extends as shown by the chain line in FIG. 4, advances the rack 79 attached to its tip to the left in FIG. 4, and the pinion 81 that meshes with the rack 79 rotates clockwise. When the frontmost stopper 83 is retracted upward (14) as shown by the chain line in the figure, the frontmost bottle 1) starts traveling. Subsequently, after a certain period of time, the stopper 83 of the second mounting member 73 similarly retracts upward, the second bottle 1) travels, and then the third and rearmost mounting member 75 As shown in FIG. 1, the stoppers 83 of the items 83 are retracted sequentially after a certain period of time. This prevents the bottles 1) from collapsing or falling from the slat conveyor D due to the bottles 1) coming into contact with each other while being carried out.

When it is detected that the rearmost bottle 1] has passed the frontmost stopper 83, the piston rods 77 of the air cylinders 76 of all the mounting members 73 are contracted, and the stopper 83 is moved as shown by the solid line in FIG. 83 returns to the protruding position, the piston rod 61 of the air cylinder 6o extends as shown by the solid line in FIG. 2, and the movable member 73 returns to its original position. The piston rod 44 of the cylinder 43 contracts as shown by the chain line in FIG. 2, swinging the support plate 38 into a vertical position that opens the opening 33.

During this time, the first stopper 9a that had been protruding from the top surface of the sliding plate 1 retreats to the bottom surface, and the endless chain 7 is driven and transferred forward by the feed rod 8, replacing the first stopper 9a. When it hits the second stopper 9b protruding from the upper surface of the sliding plate 1, the bottles l) in the center row are located directly below the window hole 11 of the base plate 10, so that the bottles 9b protrude from the upper surface of the sliding plate 1. The rod 26 pushes up the upper surface of the horizontal plate 32, the bottom surface of which is supported by the support plate 38, and as the moving member 73 advances, it slides on the horizontal transfer surface C and is transferred to the slat conveyor D, starting from the frontmost stopper 83. After a certain period of time, the ibs are retracted upward, and each ib is carried out by the slat conveyor D at a certain interval.

When the transfer of the bottles l) in the center row is completed, the second stopper 91] is retracted, and the endless chain 7 is driven to transport the packaging box a forward, and when it hits the third stopper 9C, it is finally stopped. bottle 1] in the other row is the window hole 11 of the substrate 10.
, and are transferred to the slat conveyor D by the same procedure as described above, and are further carried out by the slat conveyor D at regular intervals.

Once all the bottles have been transferred, empty the packaging box a.
are transferred from the carry-in conveyor A to an unillustrated carry-out conveyor connected in front of the carry-in conveyor A, and are carried out.
A new packaging box a containing bottles is carried in, and by repeating the above-described procedure, the bottles 1) are transferred to the slat conveyor D, and are carried out by the slat conveyor D at regular intervals.

In addition, if the interval between the moving members 73 can be adjusted, it can be applied even when the bottle type is changed. In this case, the projecting rod 26 and the pair of front and rear support plates 3
It is necessary to be able to adjust the interval of 8 accordingly.

As specifically explained in the above embodiments, the method for unboxing bottles of the present invention involves forming a through hole in the bottom surface of the packaging box by simultaneously pushing up each of the protrusions installed below. The gist of this method is to push the conveyor onto one horizontal transfer surface, support the bottom surface with a support plate, and transfer the names onto an unloading conveyor laid parallel to the parallel direction. Instead of holding the bottle by its neck and transferring it to a conveyor without being burnt, the bottom of the bottle is pushed up with a lifting rod and pushed up to the horizontal transfer surface, and then the bottom is supported by a support plate and transferred horizontally. Since the transfer is carried out along the transfer surface to the carry-out conveyor, it can be applied to bottles with thick necks, and it also prevents mistakes in taking out bottles and bottles falling during transfer, making it easier to carry bottles out of packaging boxes. The bottle unboxing device of the present invention has the effect of reliably transferring the bottles to a conveyor. Below the stopping position of the packaging boxes on the loading path for transporting the products, a plurality of lifting rods corresponding to each item are installed freely up and down directly below the title, and each of the lifting rods is installed on the horizontal transfer surface provided above the loading path. An opening is made in the upper part of the upper salary ζ1
8) A support plate is installed to open and close the opening, and an unloading conveyor that runs in a direction parallel to the title parallel direction is installed on the horizontal transfer surface, and the horizontal transfer surface 2 is connected to the running direction of the conveyor. A pushing member that moves horizontally in a direction perpendicular to the direction is provided, and the title pushed out onto the horizontal transfer surface with each thrust bar is supported by a support plate, and is pushed by the pushing member and transferred to an output conveyor. This is the gist of the present invention, and has the effect that the method of the present invention described above can be carried out reliably.
