Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is a package for automatically accumulating relatively flat and flexible packaging bags that are sequentially supplied and conveyed in a corrugated cardboard case or a bag. The present invention relates to an automatic bag accumulating device.

(Prior Art) When individually packed bags that are produced in large quantities are sequentially stacked at a certain height and then packed in a case or bag, conventionally, they are stacked by a free fall method, a suction cup suction method, or a skidding method. However, since the packaging bags are flexible and unstable, stacking mistakes frequently occur, which is a bottleneck for bag packing work.

(Problems to be solved by the invention) In view of the above, the present invention is capable of sequentially and accurately accumulating a required number of pieces in sequence without using natural force such as natural fall or skid, that is, by using a force-applying means. Yes, it greatly contributes to productivity improvement.

(Means for Solving Problems) The present invention is configured as follows to achieve the above object.

Two-stage stacking chambers with a constant storage capacity are provided at a lower position on the terminal end side of the transporting means for transporting the packaging bag, and a pushing-up means for moving up and down through the transporting band is provided, and a hinge-type packaging bag holding plate is provided at the upper position. It is characterized in that the stacking chambers are provided in a stack, and the uppermost stacking chamber is provided with a stacking chamber equipped with a pushing means for horizontally pushing out a certain number of packaging bags stacked in the chamber.

(Operation) When the packaging bag sent by the conveying means stops at a position above the extruding means, the pushing-up means operates in association with this and the packaging bags are sequentially transferred to the accumulating chamber provided above the conveying means. Make it stack.

(Embodiment 1) FIG. 1 is a side view (partial cross-sectional view) of the device of the present invention, FIG. 2 is a front view (cross-sectional view taken along line XX of FIG. 1), and FIG. FIG. 4 is a cutaway perspective view of the collecting chamber.

1 is a conveying means, and in the illustrated example, three rope belts 1
a, 1b, 1c are arrows (a) when the belt driving roller 2 rotates.
Is rotated in the direction. 3 is the rope belt 1a, 1b,
The packaging bag is placed on 1c and transported, and is sequentially sent by being packaged by a bagging machine (not shown).

Reference numeral 4 denotes a stopper provided at the terminal end portion of the transporting means 1, and an accumulation chamber having a constant volume is provided in a two-tiered manner above the packaging bag 3 stopped by the stopper 4.

As shown in FIG. 4, the accumulating chamber 5 is formed in a rectangular box body with front and rear and bottom portions opened, and bearings 6 are attached to the underlined portions of the left and right side wall plates 5a and 5b, respectively. ′ Is rotatable, and holding plates 8 and 8 ′ are attached to the respective shafts so that they can be hinged by 90 ° in a state where they are opposed to each other at the inner portions. Reference numerals 9 and 9'represent a limiting means for holding the holding plates 8 and 8'in a normally horizontal state by the above-mentioned hinge operation. The levers 10 and 10 'provided at the tips of the shafts 7 and 7'are It is carried out by engaging with adjusting rods 12, 12 'which are vertically provided from brackets 11, 11' fixed to the front and rear side wall plates 5a, 5b.

This is done by appropriately adjusting the opening degree of the hinge operation of the holding plates 8 and 8'and adjusting the nut m of the adjusting rods 12 and 12 'to appropriately change the downward height h of the rods. In addition, 13,1
3'is the lever 1 of the shaft 7, 7'for ensuring stable engagement between the levers 10 and 10 'and the adjusting rods 12 and 12'.
It is a weight provided at the opposite position from 0 and 10 '.

Reference numeral 14 denotes an extruding means arranged at the rear part of the box body, which has a structure in which an inverted L-shaped extruding plate 14b is attached to the tip of the fluid cylinder 14a.

On the other hand, 15 is a lower pressure means and is the top plate 5 of the uppermost accumulation chamber 5.
A pair of guide rods 15 are provided downward through a through hole n formed in c.
a and 15a 'are provided, the upper end is connected by the horizontal rod 15b, and the lower end is a pressing plate 16 of approximately the same size as the packaging bag 3 in the stacking chamber 5.
Is installed.

On the other hand, 17 is a lifting means, which comprises a fluid cylinder 17a and an elevating rod 17b which is elevated and lowered by the operation of the fluid cylinder 17a. In the illustrated example, the elevating rod 17b is a suction cup at the tips of four hollow tubes.
17c is installed between the rope belts, that is, 1a
And 1b and 1b and 1c are respectively raised and lowered so that two of them are opposed to each other. In the ascending process, the lower surface of the packaging bag placed on the rope belt is adsorbed by a suction cup and the accumulation chamber 5 Try to lift inside. In addition,
18 is a tube pipe attached to the lower end of each rod and is connected to a vacuum suction means (not shown), and 19 is a fluid cylinder 17a.
It is a device side bracket for fixing.

In the above-mentioned structure, when the packaging bag 3 is conveyed at a constant pitch through the conveying means 1 and comes into contact with the stopper 4 and stops, the fluid cylinder 17a is actuated in association with this and the lifting rod 17b is raised. As a result, the packaging bag 3 rises with its lower bottom surface adsorbed by the adsorption plate 17c. When this rises, the packaging bag 3 is held horizontally in the holding plates 8, 8 '.
The rear side of the lifting plate 17b is pushed up by the hinge action so that the holding plates 8 and 8 'rise vertically in the vertical direction to bypass the packaging bag 3 and return to the original horizontal state again. When the packaging bag 3 moves downward, the packaging bag 3 holds these holding plates 8,
It is held horizontally by 8 '.

Then, the operation of the fluid cylinder 17a is repeated in sequence as described above, so that the packaging bags 3 are sequentially stacked in the stacking chamber 5 from the lower stage to the upper stage. This pressing plate 16 is designed to prevent the collapse of the shape during stacking by applying a constant pressure from above the packaging bags 3 stacked in the upper stacking chamber. When it is set in the upper accumulation chamber, detection means such as a photoelectric tube (not shown) operates and the fluid cylinder 14a operates, and the pushing plate 14
The stacking packaging bag on the holding plates 8 and 8'is pushed out in the direction of the arrow (b) via b, and the stacking packaging bag is conveyed from the front opening of the stacking chamber 5 to a pallet table or another conveyance. Will be transferred onto the means.

(Effects of the Invention) The present invention is configured as described above, and according to the present invention, it is possible to sequentially and accurately and automatically accumulate a certain number of required fixed numbers, which is compared to the conventional free fall or skid. Since it will be stacked in a stable shape without causing any shape collapse and the required fixed number of pieces will be automatically sent out as appropriate, work such as packing in the next process can be performed completely unattended. It will be possible to improve the productivity drastically.
