Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an Eζ
This invention relates to an automatic cushioning device for filling cushioning materials to prevent damage to the product.

BACKGROUND TECHNOLOGY AND PROBLEMS - Conventionally, when tablets are stored in a required plate or other container and shipped, the tablets may break due to vibrations applied to the bottle or drug during transportation. This happens when the container is empty (■) and the drug moves randomly, colliding with the inner wall of the bottle or container or with each other and being damaged by the impact force.To prevent this, Cζ is filled with the drug. After that, to fill the space inside the container, antiseptic cotton or sponge is pushed in and filled.However, cotton has the disadvantage that the cotton fibers such as chemical C stick to it, and sponge has the disadvantage that it picks up the odor of the material. In order to prevent this, a method has recently been put into practical use in which synthetic resin films such as polyethylene are cut to the required size and then rolled up and filled into containers. In other words, containers filled with drugs are fed onto a turntable at a fixed pitch, and the containers are moved as the turntable is driven, and a film-pushing device is placed above the turntable and opposite each container. The rod and pipe are arranged as a set, and each rod pipe is rotated in synchronization with the rotation of the turntable, and the film supplied at one position is lowered by the lowering operation of the rod at another fixed position. The film is rolled up and pushed into the container at the same time.This not only increases the size of the device, but also requires a pushing mechanism for each container, making the mechanism complicated.

Therefore, in view of this, the present invention simplifies the mechanism, shortens the operating time, improves production capacity, and provides a method for reliably producing cushion film according to the size of the container. A cutting means for cutting the resin film into a fixed size and a feeding means for further feeding out the cut film are provided in the middle of the means for sequentially feeding out the wound resin film from the film roller. The feeding means and cutting means are of a variable adjustable type so that the length of the filled film can be cut variably according to the size of the container, etc., and a means for rolling the film and pushing it into the container is provided at a position in front of the feeding means. At the same time, this pushing means consists of a pair of Miki push rods that can be moved up and down in a variable manner according to the height of the container, and a guide pipe that is arranged below each of the rods so that the rod can be inserted. Two parallel guide pipes are positioned at a film supply position close to the feeding means and at a push position on the dovetail feed line of the container, and the guide pipes are rotated while turning the guide pipes upside down to alternate the positions. By changing the pipes, the vertical rotation of the pipe, the raising and lowering of the push rod, and the intermittent feed speed changes of the container conveyance line are synchronized.

Example The present invention will be described below based on embodiments shown in the drawings.

FIG. 1 is an explanatory diagram showing an outline of the entire cushioning material pushing device of the present invention, which includes a film roll winding a polyethylene film tube and other films F to be filled in a container B, guide rollers Gl, Gz, Gs,・Gn
The trowel is successively guided and unrolled, and an unwinding roller 1.1 is disposed near this final guide roller Gn or in the middle of unwinding the film, and the film F is fed by the roller 1.1. A cutter 29 is disposed close to this feeding roller 1, and a cutter 29 is disposed close to this feeding roller 1, and a cutter 29 is disposed in the vicinity of this feeding roller 1 to roll out the film F. Cut to a predetermined length. This cutter 2 may have an elevating cutting blade and cut the unrolled film with the elevating and descending blade, but for more effective cutting, rotating rollers are placed above and below the film, and the blade is attached to this roller. The blades 2@ of the upper and lower rollers may be synchronized with the roll-out of the film, and the film may be cut at zero when the blades 2@ of the upper and lower rollers coincide with each other vertically. Further, a feeding device t1 is provided in close proximity to the cutter so that the film F cut to a fixed size is held and accurately fed out. This feeding device 3 has rollers sa and sb arranged at both ends as shown in detail in FIG. 2 and below.

A belt conveyor with an endless belt SC stretched between sb is installed vertically, and a one-car belt conveyor I
When IA and JIB are driven synchronously by moving the roller 11°, the film F cut to a fixed size is sandwiched between the upper and lower belt conveyors 8A and sB and sent to the next process side. This roller S@ and cutter 2. As shown in the figure, the feed rollers 1 are driven in synchronism by meshing straight shafts fixed to the ends of each shaft with each other either directly or through intermediate gears. The film pusher half-recessed 4 adjacent to the feeding device 8 moves up and down 2
It consists of wooden push-in rods aa and ah placed above and two wooden guide pipes IIλ and sb placed below, which are vertically opposed to each other. More specifically, the push rods 4λ and 4b are vertically installed so as to project downward from a lifting frame 42 that is slidably supported by a guide rod 41 that is vertically projecting from the main body frame.
Lifting frame 4! is locked to the lifting arm 48, and by moving the arm 4s up and down, the lifting frame, that is, 2
This is to raise and lower the book push rods aa and ah at the same time. Even if this arm 48 is replaced with a cylinder, similar lifting and lowering operations can be performed. And these two push-in rods 4λ, ah have one side 41 connected to the guide pipe 52. Or, push down the center part of the film F cut to a fixed size in 6b, fold the film in half at the center, roll it up, and push it into the guide pipe, and use the other pushing rod 4b to push the film into the guide pipe. In other words, the guide pipe is turned upside down and filled into the container.

These two push rods 4@ and 4b are used to position the push rod 4@ and 4b in the vicinity of the feeding device, and to position the push rod 4b outward from this position on the line for conveying containers such as bottles. Both rods a@, ab is rod 4b
is slightly longer than the rod 4a.

Both of the guide pipes 5a and fib have the same diameter and length, and are adjacent to the core device @3 at a position below the film line sent out from the feed device @3, and this guide/fib is upside down. and two 'push rods a2
It moves alternately between L and ah. This is the side direction from the main frame, that is, the feeding side of the film cut to a fixed size. The tooth shaft 52 is fixed, and the bevel gear 1 and the two bevel gears 511. ! i4 are arranged opposite to each other and meshed with each other, and a shaft 56°s6 is fixed to this bevel gear 1'ia6g4, and these two wheels 5g and 58 are arranged on the same axis. s@, t4 Eve supporter 5 that holds ib? ,! is provided, and the shaft 61
Rotation 1 For example, sprocket wheel 5g installed at the end of the shaft
By rotating it with a chino, the bevel gear 1sIs, 5

This allows the guide pipe to be reversed up and down and moved at the same time, and the reversal and movement (swivel) of the guide pipe are synchronized with the vertical movement of the push rods aa and 4b.

The conveyance line for containers such as bottles is disposed below the reversing transfer section of the guide pipe and is vertically adjustable so that the mouth edge of the container and the lower edge of the guide pipe are close to each other. This is a belt conveyor or the like, and guides are provided on both sides of the conveyor line conveyor 6 to prevent containers from coming off the line conveyor. In addition, this guide 61 can be varied depending on the size of the container.

The length of the film to be cut is 1. Cutter 2. A slide frame having a feeding device 8 is supported movably in the film feeding direction with respect to the main body frame.

By rotating the adjustment screw 8 using the handle S a C, the slide frame 7 is moved forward and backward, thereby changing the cutting position by the cutter, and the film is placed on the push frame Fλ by the feeding device @3. This is done by changing the distance from the stopper S that has sunk onto the table 9. This is determined appropriately depending on the size of the container, especially the space inside the container.

The film F cut to a fixed size is held by a belt conveyor type feeding device.

When a film is placed on the table by driving the device, a push rod 41 is pushed from above toward the center i of the film.
is lowered and passes through a window hole (not shown) that served as a table, and the film F is pushed into a guide pipe waiting below the window hole so as to be rolled up. And push rod 4 turtles. When 4b rises, the side pipe is turned upside down by the drive of the bevel gear, and the one under the push rod 4λ is placed under the other rod 4b, and conversely, the one under the rod 4b is placed under the rod 4 friend. is changed and replaced. This operation is performed alternately +C sequentially. The guide pipe into which the film has been pushed is then moved to the push rod 4b.
When the film descends, the film inside the pipe is pushed out of the pipe by the rod 4b, which is longer than the rod 43.

It is inserted into a container located below the lower end of the pipe. At this time, the film that is pushed into the container has both edges folded in half first, the center part facing backward, and the film is then pushed into the container and acts as a cushioning material. This push rod 4a.

When the film 4b is simultaneously lowered, the film is pushed into the guide pipe on the one hand, and the film is pushed into the container from the guide pipe on the other hand at two different points at the same time.

Effects of the Invention The present invention includes a push rod for pushing a film cut to a fixed size into an id pipe.

A push rod is used to insert and fill the film pushed into the guide pipe into the container! The books are placed side by side and raised and lowered at the same time, guide pipes are placed above both rods, and the two guide pipes are turned upside down and their positions alternately changed. Because of this, the structure is extremely simple, and the film can be reliably filled into the container as a cushioning material.Moreover, the film is simple to operate, so it can be driven quickly in synchronization with the speed of the container conveyance line.
