[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for disassembling a bulk packing bottles and feeding the packed bottles in a row.
[0002]
[Prior art]
Bottles used for filling beverages and the like are carried into a filling factory in a package called bulk. In the filling factory, the bulk is dismantled, the bottles are arranged in a row, and the beverage is filled with a filling machine. In the bulk, bottles are placed in a matrix (vertical and horizontal) with the bottles standing on the pallet, and the bottles are stacked in multiple layers on the pallet by placing a stacking sheet on it and then arranging the bottles vertically and horizontally on it. Finally, it is a packing body in which a stacking sheet is placed on the top, and the periphery is wrapped with a transparent tape and fastened with a band.
[0003]
Disassembling the bulk is performed by cutting the fastening band, removing the transparent tape wound around it, removing the stacked sheets in order from the top, and feeding the bottles of each layer onto the conveyor. For the bottles having a circular cross section or a regular square cross section, the bottles of each layer are collectively fed onto a conveyor and then aligned in a row by a guide. FIG. 6 is a diagram schematically showing the method. A bottle fed from the bulk 1 to the alignment conveyor 3 by the pusher 2 is composed of a plurality of belts 3a... 3f having a speed difference in the width direction. By the action of the aligning conveyor 3 and the aligning guide 4, they are sent out in a line on the extension of the fastest belt 3a. This method cannot be used for bottles of rectangular cross section because the sides cannot be aligned.
[0004]
FIG. 7 shows another method that can be used for bottles having a rectangular cross section. The bottles of each layer are sent out from the bulk 1 onto the conveyor 3 one by one by the intermittent advance of the pusher 2. This method has a feature that the installation space of the apparatus is small and can be sent out without destroying the alignment state of the bottles on the bulk. However, this method cannot be used for a bottle having a circular section. This is because, as shown in FIG. 5, the circular cross-section bottles are accommodated in a staggered pattern in which the positions of the columns are shifted on the bulk. If the bottles arranged in a staggered pattern are to be carried out in a tangential direction one by one, the portion biting into the adjacent row is caught and cannot be carried out.
[0005]
[Problems to be solved by the invention]
This invention makes it a subject to provide the bulk dismantling apparatus which can send out the bottle of circular cross section, a regular cross section, and a rectangular cross section in a line from a bulk on a conveyor.
[0006]
[Means for Solving the Problems]
The bulk dismantling apparatus of the present invention that has solved the above problems is a bulk dismantling apparatus in which bottles mounted in a matrix (vertical and horizontal) on a stacking sheet 40 are sent one by one onto the carry-out conveyor 8 by a pusher 19. And a lifting device 41 for lowering the conveyor surface 8a after receiving the bottle, and an overfeed pusher 22 for separating the bottle on the lowered conveyor surface 8a from the bottle on the bulk side. After receiving, the conveyor surface 8a descends vertically and the overfeed pusher 22 pushes the bottom of the bottle on the conveyor surface lowered to separate it from the bottle on the bulk side, and then the carry-out conveyor 8 runs. It is characterized by.
[0007]
The bulk dismantling apparatus according to claim 2 is a bulk disassembling apparatus having the above-described configuration, wherein the conveyor surface 8a of the carry-out conveyor 8 is moved up and down by the lifting and lowering operation of the guide plate 33 guiding the back surface of the conveyor surface.

A chain conveyor 10 is provided at the bottom of the bulk dismantling unit 6 in conjunction with the chain conveyor 9 of the bulk carry-in unit, and a pantograph type bulk lifting device 11 for raising and lowering the chain conveyor 10 is further provided below the chain conveyor 10. It has been.
[0010]
A guide 14 and a rack 15 for guiding a sheet carrier 12 that reciprocates between the bulk disassembly unit 6 and the sheet storage unit 7 and a pusher base 13 described later are provided on the upper part of the bulk disassembly unit 6 and the sheet storage unit 7. The sheet carrier 12 includes a motor 16 that reciprocates, a suction pad 17 that moves up and down, and a detection rod 18 that detects a raised position of the bulk. The motor 16 rotates the pinion that meshes with the rack 15 to reciprocate the sheet carrier 12 between the bulk disassembly unit 6 and the sheet storage unit 7.
[0011]
When the bulk is lifted by the bulk lifting device 11 in a state where the sheet carrier 12 is waiting above the bulk dismantling unit 6, the detection rod 18 is pushed up by the stacked sheet at the top, and the pushed-up position is When the predetermined position is reached, a signal is output to stop the bulk lifting device 11. When the height of the bottle accommodated in the bulk changes, by changing the length of the detection rod 18 or changing the detection position when it is pushed in, the stacked sheet carrying the uppermost bottle is When the predetermined height is reached (height of the carry-out conveyor), the bulk lifting device 11 is stopped. After that, the suction pad 17 slightly moves down to suck the stacked sheets placed on the bottle, the sheet carrier 12 moves onto the sheet storage unit 7, and the stacked sheets are transferred from the suction pad 17 to the sheet storage unit 7. Let me leave.
[0012]
1 and 2 are a front view and a side view showing details of the top of the bulk dismantling part and the carry-out conveyor. A pusher base 13, a pusher 19 mounted on the pusher base, a side guide 20, a sheet clamp device 21, and an overfeed pusher 22 are provided on the bulk disassembly unit 6. Further, a bottle upper presser device 23 is provided above the carry-out conveyor 8. Further, the anti-bulk guide 24 and the guide bar 25 and air cylinders 39 and 42 for advancing and retreating them are provided on the unloading conveyor 8 on the side opposite to the bulk dismantling part.
[0013]
The pusher base 13 reciprocates in the same direction as the sheet carrier 12. The pusher 19 is mounted via the elevating cylinder 26 and protrudes downward. The pusher base 13 reciprocates above the bulk dismantling unit 6 by rotating a pinion that meshes with the rack 15 by a motor 27 mounted thereon.
[0014]
The side guide 20 is a guide that prevents the bottles from spreading sideways when the bottles arranged vertically and horizontally are pushed together to the carry-out conveyor 8 side by the pusher 19. When the bulk moves up and down, the side guide advance / retreat cylinder 28 is used. Is evacuated. The sheet clamp device 21 is a device that grips the side of the stacked sheet on the side opposite to the unloading conveyor in order to prevent the stacked sheet 40 on which the bottle is placed from moving together with the bottle when the bottle is pushed by the pusher 19. It is. The height of the stacked sheets on which the bottles to be pushed out to the carry-out conveyor 8 are fixed regardless of the height of the bottles by adjusting the length of the detection rod 18 or adjusting the detection height. The height of 21 is always constant. Reference numeral 29 denotes a cylinder for positioning the horizontal position of the sheet clamp device 21.
[0015]
The carry-out conveyor 8 receives a row of bottles pushed out from the bulk by the pusher 19 and then the conveyor surface is lowered by the lifting device 41 described later. The overfeed pusher 22 pushes a predetermined amount in the direction to further separate the bottom of the bottle on the carry-out conveyor 8 from the bulk after the conveyor surface is lowered, and overfeeds both ends of the horizontally mounted bar. This structure is pushed by the cylinder 30. The guide bar 25 advances simultaneously with the advance of the overfeed pusher 22 and guides the bottle pushed onto the carry-out conveyor 8.
[0016]
Note that a jumper plate 31 is provided between the bulk and the carry-out conveyor 8, and the overfeed pusher 22 is located immediately below the jumper plate 31. The transition board 31 fills the gap between the bulk inserted into the bulk dismantling part and the carry-out conveyor 8. The transition plate 31 is composed of two comb-like plates in which teeth are combined in the same plane, and the bulk-side comb-teeth plate can be retracted when the bulk is raised and lowered.
[0017]
The carry-out conveyor 8 is a plate conveyor in which a face plate forming a conveyor surface is attached to each chain link, and a guide plate 33 for guiding the upper (loading side) chain is provided between the sprockets 32 and 32 at both ends. And the conveyor surface 8a of a carry-out conveyor is raised / lowered by raising / lowering this guide plate. That is, the conveyor surface 8a of the carry-out conveyor rises to the same height as the jumper plate 31 when the bottle is pushed out by the pusher 19, and descends to the carry-out height after receiving the bottle. By lowering the conveyor surface of the carry-out conveyor, the bottom of the bottle placed thereon is lowered to a position where it is pushed by the overfeed pusher 22 below the bridge plate 31.
[0018]
The upper presser device 23 includes two presser bars 34 and 35 extending in a direction parallel to the carry-out conveyor 8. The first presser bar on the bulk dismantling part side is fixed to a mounting plate 37 fixed to the rod of the first lower moving cylinder 36. On the other hand, the second presser bar 35 located immediately above the carry-out conveyor 8 is attached to the attachment plate 37 via a second lower moving cylinder 38. When the bottle is pushed out onto the carry-out conveyor 8 by the pusher 19, the first lower moving cylinder 36 operates to move down the presser bars 34 and 35 to hold the bottle head. At this time, the second downward movement cylinder 38 is also urged downward, and when the conveyor surface 8a of the carry-out conveyor is lowered, the second presser bar 35 is also lowered along with the downward movement of the bottle. These presser bars 34 and 35 are provided to prevent the bottles on the carry-out conveyor 8 and the bottles adjacent thereto from falling down.
[0019]
The fall prevention guide 24 is a belt-like guide for preventing the front row of bottles pushed out by the pusher 19 from falling forward. When the bottle is pushed by the pusher 19, the fall prevention guide 24 is pressed against the front surface of the bottle in the foremost row by the air cylinder 39, and the pusher 19 advances as the pusher 19 advances due to the magnitude relationship of the pushing force with the pusher 19. fall back. Then, after the bottles in the front row are pushed out onto the carry-out conveyor 8, they are retracted before the conveyor surface 8a is lowered.
[0020]
The operation of the apparatus having the above structure will be described below.
[0021]
The bulk carried into the bulk carrying-in part 5 is transferred into the bulk dismantling part 6 by the chain conveyors 9 and 10 after the fastening belt and the transparent tape wound around are manually removed. At this time, the pusher base 13 has moved to the carry-out conveyor 8 side, and the sheet carrier 12 has moved to the upper part of the bulk dismantling unit 6. In this state, the bulk elevating device 11 is raised, and the loading sheet at the top of the bulk pushes up the detection rod 18, and the loading in which the uppermost bottle is placed at a predetermined position set according to the height of the bottle. When the sheet 40 reaches the height of the crossover plate 31, the raising operation of the bulk lifting device 11 is stopped. In this state, the suction pad 17 of the sheet carrier 12 is lowered to suck the stacked sheet placed on the uppermost bottle, and the suction pad 17 is slightly degenerated to lift the sucked stacked sheet. 12 moves onto the sheet storage unit 7. Then, the stacked sheets 40 are dropped into the sheet storage unit 7 by releasing the negative pressure of the suction pad 17.
[0022]
In parallel with the movement of the sheet carrier 12, the pusher base 13 retracts the pusher 19 upward, then moves to the sheet storage unit 7, stops when the top of the bulk is exceeded, and lowers the pusher 19. On the other hand, the side guide advancing / retracting cylinder 28 advances the side guide 20 to guide the side surface of the uppermost bottle, and the sheet clamp device 21 moves forward and closes so that the stacking sheet on which the uppermost bottle is placed is counteracted. Clamp the side of the carry-out conveyor. Moreover, the crossover board 31 spreads to the bulk side and forms the guide surface of the bottle between the bulk and the carry-out conveyor 8.
[0023]
Next, the fall prevention guide 24 moves forward, and the pusher 19 moves forward with a stronger force, thereby pushing the front row of bottles onto the carry-out conveyor 8. When the front row bottles are pushed onto the carry-out conveyor 8, the pusher 19 stops, the upper presser bars 34 and 35 are lowered, the heads of the front row and second row bottles are pressed, and the fall prevention guide 24 is After the retraction, the guide plate 33 of the carry-out conveyor is lowered, the conveyor surface 8a is lowered, and the front row of bottles pushed onto the second plate 35 and the second presser bar 35 holding the head thereof are lowered accordingly. .
[0024]
When the bottle is a circular cross-section bottle, in this state, the front row bottle and the second row bottle are still overlapped with each other. Accordingly, the overfeed pusher 22 is advanced, and the overfeed pusher 22 pushes the bottles on the carry-out conveyor 8 in the direction separating the bottles from the second row, thereby causing interference between the first row bottles and the second row bottles. Solve. At the same time, the guide bar 25 moves forward. Then, the carry-out conveyor 8 is driven to feed out the first row of bottles pushed out thereon.
[0025]
When the row of bottles is sent out, the fall prevention guide 24 moves forward again, the conveyor surface 8a of the carry-out conveyor moves up, and the pusher 19 moves forward by one row while the upper presser bars 34 and 35 are retracted upward. The next row of bottles is delivered onto the carry-out conveyor 8. By repeating this operation, when the uppermost bottle is sent out from the bulk, the sheet carrier 12 moves again to the upper part of the bulk dismantling unit 6, and in that state, the bulk lifting device 11 carries out the next bottle. Raise the bulk until it reaches height.
[0026]
By repeating the above operation, the bottles accommodated in multiple layers on the pallet are sent out from the carry-out conveyor 8 one by one.
[0027]
【The invention's effect】
According to the bulk dismantling apparatus of the present invention described above, the vertical movement of the conveyor surface of the carry-out conveyor and the excessive movement of pushing the bottles on the conveyor away from the next row of bottles when the conveyor surface is lowered. By providing the feeding device 22, even when circular cross-section bottles or the like are placed in a staggered manner in bulk, the bottles can be separated and transported smoothly. And, since the conveyor surface of the carry-out conveyor is moved up and down by moving the guide plate that guides the upper surface of the conveyor between the sprockets at a certain height, instead of moving the entire conveyor up and down, the mechanism Can be improved, and the maintenance and durability of the apparatus can be improved. That is, the apparatus of the present invention provides an economical apparatus that can take out bottles of various shapes such as a circular cross section, a regular polygon cross section, a rectangular cross section, etc. one by one from the bulk and carry them out with a single apparatus. There is an effect that can be.
