Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an empty can press device using eccentric rolls for pressing empty cans such as cans of beer, cans of juice, and oil cans to reduce their volume and facilitate recovery processing. It is.

Although a roll press device for pressing empty cans into a flat shape has been provided, there has been a problem in that the empty cans are not easily caught between the rolls.

The present invention solves these problems by reliably pressing empty cans by rotating rolls arranged closely in parallel at constant intervals and eccentrically in opposite directions. The purpose is to provide a roll press device.

A further object of the present invention is to provide an empty can roll press device that is provided with rolls in which empty cans placed between the rolls are reliably bitten without sliding between the rolls.

Another object of the present invention is to provide an empty can roll press device in which the empty cans inputted from the input port are not input between many rolls at once, but are inputted one by one and reliably pressed. shall be.

The present invention will be explained based on the drawings. Reference numeral 1 denotes a machine frame made of metal and formed into a box shape. An input port 2 is opened at one side above the frame, and an output port 3 is opened at the bottom on the opposite side of the input port 2. ing.

An electric motor 4 is fixed to the machine frame 1 above the machine frame 1, and a sprocket 5 is coaxially attached to the rotating shaft of the electric motor 4.

6 is an upper roll made of cemented carbide and formed into a cylindrical shape, and a support shaft 8 is attached at a position offset from the center point 7, and both ends of the support shaft 8 are attached to the bottom plate 1a of the machine frame 1. The support shaft 8 is supported by vertical support stands 9a and 9b, and the support shaft 8 passes through the support stand 9a and is inserted between the support stand 9a and the machine frame 1.
A sprocket 10 and a gear 11 are coaxially mounted on a support shaft 8 with an upper roll 6.

Sprocket 5 coaxial with electric motor 4 and upper roll 6
A chain belt 12 is suspended endlessly between a sprocket 10 coaxial with and.

Reference numeral 13 denotes a lower roll, which is a cylinder made of cemented carbide and has an elliptical cross section.A support shaft 15 is attached at a position offset from the center point 14. Both ends of 15 are supported by bearings 9a and 9b.

The support shaft 15 passes through the support stand 9a, and a gear 16 is attached to the support shaft 1 coaxially with the lower roll 13 between the machine frame 1 and the support stand 9a.
It is pivoted to 5.

The gear 11 and the gear 16 are rotatably meshed with each other, and the gear 11 and the gear 16 are formed within the same pitch.

The upper roll 6 and the lower roll 13 are rotatably arranged adjacent to each other in the vertical direction in the machine frame 1 and in opposite directions and are supported in parallel. It is supported by support stands 9a and 9b on the line.

17 is a guide guard and upper and lower rolls 6 are arranged side by side from the input port 2.
．． It extends in two stages in a semi-circular arc shape towards the space between 13 and is attached to the machine frame 1 with a downward inclination.

Reference numeral 18 denotes a receiving plate mounting plate, which is fixed to the inside of the machine frame 1 at the lower end of the guide guard 17, and is fixed to the inside of the machine frame 1.
A receiving plate 19 is provided to project downwardly from approximately the center of the roll 6° 13 toward the space between the upper and lower rolls 6°13.

Reference numeral 20 denotes biting grooves, and a large number of biting grooves 20 are bored parallel to the axis on the outer peripheral surface of the upper and lower rolls 6.13, and as shown in FIGS. A groove side surface 21 is formed perpendicular to the outer peripheral surface of the upper and lower rolls 6°13.

22 is a discharge guide guard which guides the upper and lower rolls 6 from the discharge port 3.
It is attached inside the machine frame 1 diagonally upward toward the machine frame 13.

In FIG. 2 showing an embodiment of the present invention, the upper roll 6 is a cylindrical shape with a diameter of 89.1 ram, the lower roll 13 is an elliptical cylinder with a maximum diameter of 96.1 mm and a minimum diameter of 81.1 mm, The distance between the center point 8a of the support shaft 8 of the roll 6 and the center point 7 of the upper roll 6 is set to 20 m, and the support shaft 8 is attached to the upper roll 6 with the support shaft 8 biased to the left of the center.

The center point 15a of the support shaft 15 of the lower roll 13 and the lower roll 1
The support shaft 15 is attached to the lower roll 13 with the distance from the center point 14 of the roll 3 shifted to the right by 20 degrees in the direction of the short axis 13a.

The support shafts 8 and 15 of the upper and lower rolls 6.13 are located on the same perpendicular line, and the distance between the support shafts 8 and 15 is 90 m, and the long axis 13b of the lower roll 13 is tilted 12 degrees to the left with respect to the perpendicular line. Then, the lower roll 13 is pivoted.

In this case, the upper and lower rolls 6.13 were always rotated in opposite directions with a distance of about 6 mm apart, and favorable results were obtained.

5 and 6 show an embodiment of a biting groove 20 formed on the outer peripheral surface of the upper and lower rolls 6.13. A favorable result was obtained by biting and pressing.

In the present invention, the rotation of the electric motor 4 serving as a drive source is transmitted to the upper and lower rolls 6.13 via the chain belt 12, so that the upper and lower rolls 6.13 are close to each other and rotate in opposite directions to each other, and the air that is charged from the input port 2 is rotated. The can 23 is pressed between the upper and lower rolls 6.13 and is dropped into the outlet 3.

Since the present invention is configured as described above, the upper and lower rolls are close to each other and rotate in opposite directions while always maintaining a constant distance, so that empty cans that have been put in are reliably pressed and discharged, and the upper and lower rolls are eccentric rolls. Because of this, the lower roll pushes the empty can between the upper and lower rolls from below and engages it, so the empty can is reliably pressed without sliding between the upper and lower rolls.

Since a large number of biting grooves are arranged in parallel on the outer circumferential surface of the roll, the groove sides are perpendicularly perforated, empty cans are reliably bitten and pressed by the biting grooves in the outer circumferential direction of the roll.

The guide guard is slanted from the input port and layered in two layers in a semi-circular arc from approximately the center, so that empty cans do not fall in large numbers at once between the upper and lower rolls. Since the cans are dropped one by one, there is no risk of empty cans getting stuck between the upper and lower rolls, and the empty cans can be pressed reliably and smoothly.
