Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bottom plate removal device in a bottle feeding device.

In the case of medicines such as tablets and injections, the bottles are made by a bottle maker and immediately stacked in several tiers with the openings facing downward in cardboard boxes with floor plates in between.

The reason why the bottles are stored in the box with the enlargement facing downward is to prevent fine dust from inside the factory from getting into the bottle, and bottles that are made with the enlargement facing downward are placed in the case as is. - are stacked in several tiers inside the box,
Furthermore, when opening a box in a pharmaceutical factory, it is customary to open the bottle from the bottom and place it face up on a turntable. This is because we tried to prevent this as much as possible.

Also, depending on the size of the bottle, the number of stacking stages is divided into 2 to 4 stages.
Moreover, the number of boxes packed varies from 100 to 760 pieces.

The bottles packed in boxes in this manner are opened at a pharmaceutical factory and then placed face up on a turntable by hand, and then sent to an air cleaner device where the inside surface is cleaned and filled with drugs, etc.

Manually feeding the boxed bottles onto the turntable in this way is a relatively hard labor.
Furthermore, touching the bottle with your hands, even if you clean it, is not sanitary, and automatic feeding was desired.

This problem was resolved in the patent application filed by the applicant in 1973.
67363 and Japanese Patent Application No. 50-67364, the present invention aims at saving labor by automatically removing the bottom plates between groups of bottles by changing the manual removal of the bottom plates in this device.

After explaining the details of the embodiment with reference to the drawings, the above-mentioned bottle boxes 2 fed onto the roller conveyor 1 of FIG. 1 are manually opened.

As mentioned above, the bottle 3 is packed in the box 2 with the enlarged side facing downward, and the box 2 containing enough volume is manually placed into the pocket of the reversing mechanism 4 so that the flap of the box 2 is horizontal. It is housed in section 4'.

When the cylinder 5 is started, the shaft 8 of the reversing mechanism 4 is rotated by 180 degrees due to the meshing relationship between the rack part 6' provided on the rod 6 of the cylinder 5 and the pinion 7, and the box 2 is moved upward in an inverted state. Ru.

180° rotation is determined by limit switches 9 and 10.

The cylinder 11 is actuated by the reversal signal from the reversing mechanism 4, and the box 2 which has been inverted by the action of the locking plate 12 attached thereto is moved from point A to B while sliding on the frame body 13.
The stroke is determined by limit switches 14 and 15 until the point is reached, and then stopped.

At this stopping point, a bottle group mounting table 16 is waiting, and the bottle group is placed on this table 16.

A motor 17 is driven by a box movement stop signal, and a rod 18 is lowered to take out a group of bottles stacked in several stages on a platform 16 from the box 2 and further move this group of bottles downward.

The platform 16 for this field group is located in a space made of cedar bark in the frame-like body 13, and is surrounded on at least two sides by movable and adjustable side walls, so the bottles are guided by these walls. It won't fall over.

This is not particularly illustrated, but the earlier patent application filed in 1970-
67363.

In connection with this operation, another cylinder 19 operates, and by the action of a locking plate 20 provided thereon, the empty box 2 is ejected out of the frame-shaped body as shown in the figure.

This action is performed by limit switches 21,22.

The bottles on the bottle group mounting table 16 are adjusted upward until the bottom of the top group of bottles coincides with the surface of the frame-shaped body 13, that is, the surface of the dispensing section 24 which is on the same surface as the surface of the turntable 23. However, this determination is made by a combination of the program scale 25 determined by the size of each bottle and the phototube devices 26 and 27.

The uppermost group of bottles is disposed in a U-shaped planar extrusion member 28 that fits the planar area of the bottle group, and then the extrusion member 28 is pushed in the direction of the arrow by the action of the cylinder 29, and the bottle group is placed in one step. The group of bottles is transferred onto the turntable via the dispensing section 24.

The transferred bottles are transferred onto a conveyor 30 to Knoner by the rotating action of the turntable 23, and are subjected to predetermined washing.

The present invention relates to a device for removing a bottom plate 31 provided between an upper group of bottles and a lower group of bottles, and will be described below.

As is clear from FIGS. 2 to 4, when the rod 34 is actuated by the actuation of the cylinder 33 equipped with the operation bundle 32 for position adjustment, a lever 35 with one end pivotally supported at the tip of the rod 34 is attached to the frame-like body. The shaft 36 is rotated, and a long lever 37 having one end fixed to the shaft 36 is rotated.

This lever 37 is provided with a guide elongated hole 38 as shown in the figure, into which a pin 41 of a holder 40 that is slidably fitted into a guide rod 39 horizontally attached to the frame-shaped body 13 is inserted. .

As is clear from FIG.
A central portion of a support rod 42 perpendicular to the guide rod 39 is fixed to the support rod 39 .

An air cylinder 43 is rotatably attached to both ends of the support rod 42, and a bent corner portion of a bottom plate catch member 44 having a 1" side shape is pivotally attached to the tip of the air cylinder 43. Further, the end of the rod shaft 45 of the air cylinder 43 is connected to the vertical rod portion of the bottom plate catch member 44.

A downward needle rod 46 is fixed to the lower surface of the tip of the horizontal rod portion of the bottom plate catch member 44.

A support plate 47 is attached to the side of the rear end of the air cylinder 43, and a spiral spring 49 of the same strength is connected between both sides of this plate and the downward U-shaped member 48 attached to the support rod 42.
are respectively resiliently installed so that the air cylinder 43 can rotate in the direction of the arrow and automatically return to the neutral position.

Next, to explain the operation of the main structure of the present invention described above, before the cylinder 29 operates and the uppermost group of bottles is dispensed by the pushing member 28, the cylinder 3 shown in FIG.
3 is activated and the guide rod 3 is moved through the levers 35 and 37.
The holder 40 fitted to the holder 9 is moved forward.

Then, when the holder 40 moves forward by the required stroke,
A notch 50 is formed in the rear side of the extrusion member 28 by the tips of the bottom plate catch members 44 disposed at both ends of the support rod 42.
It is slightly protruded from inside the bottle group.

At this time, if the tip of the bottom plate catch member 44 hits the bottle, the air cylinder 43 rotates to either the left or right against the spiral spring 49 to prevent damage to the bottle.

The bottom plate catch member 44 is in the above-mentioned state, that is, the holder 40
The air cylinders 43 at both ends of the support plate 42 are actuated by a signal indicating that the bottom plate catch member 44 has moved forward by a predetermined stroke, and the rod 45 moves as shown by the chain arrow in FIG. The needle rod 46 is rotated downward to pierce the rear end edge of the bottom plate 31 located between the bottle groups from above.

Then, as described above, at the same time as a predetermined group of bottles is dispensed by the pushing member 28, the cylinder 33 and the lever 35
．． 37 moves the holder 40 backward, and the bottom plate 3
1 to the rear and automatically drop the frame-shaped body 1.
It is discharged to the outside through the chute 51 of No. 3.

At this point, the air cylinder 43 is activated to return the bottom plate catch member 44 to its original state as shown in FIG.

This completes one operation, but then the bottle group platform 16 is raised by the weir height by the action of the program scale 25 and the phototube device, and the same operation is repeated.

When all the bottles in one box have been dispensed, a new group of bottles is supplied in the manner described above, and the same operation is automatically performed again.

As described above, according to the present invention, it is possible to automatically remove the floor plates placed between the groups of bottles with a simple configuration, and it has practical effects such as completely saving the labor that was previously required for removing them manually. It's large.
