Abstract

PURPOSE:To enable adhesive objects to be changed in the direction without hindrance. CONSTITUTION:A roller table 5 furnished with a plurality of small rollers 3 and large rollers 4 is provided below the end faces of a plurality of stripe shaped belts 2 of a belt conveyor 1 in such a way as to be freely moved up and down. The upper ends of the small rollers 3 and the large rollers 5 are made flush with each other, and the upward movement of the roller table 5 permits the upper ends of the small rollers 3 to be slightly projected out of the strip shaped belts 2. A push-out mechanism 6 having an arm 6a and a pressing section 6b is provided for the side of the small rollers 3 of the roller table 5, to allow the pressing section 6b to be moved up when there is no object S on the roller table 5, and to allow the pressing section 6b to be moved down so as to force the object S to be pushed out in the rotational direction of each small roller 3 when the object S is delivered onto the roller table 5 with the roller table 5 moved up.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an object transfer device suitable for carrying an object having an adhesive property such as bun.

[0002]

2. Description of the Related Art Conventionally, for example, when transferring an object having adhesiveness for packaging, the object is mounted on a belt-shaped belt of a conveyor and conveyed near a rotary table for packaging, and further laterally from here. Must be transferred on a rotating table in the direction. When transferring an object from the belt to the rotary table, it is necessary to consider the effect of adhesion of the object.For example, a robot mechanism is used to lift the object vertically from the belt and transfer it to the rotary table. Often

[0003]

However, in the above-mentioned conventional example, since the robot mechanism is expensive, the whole apparatus becomes expensive.

An object of the present invention is to solve the above-mentioned problems and to provide an inexpensive object transfer device capable of delivering and receiving objects without using a robot mechanism.

[0005]

An object transfer device according to the present invention for achieving the above object comprises a belt conveyor having a plurality of strip belts, and the strip belts below the strip belts. A plurality of rollers that move up and down relative to each other and can rise from above the strip belt to a level slightly above the upper surface of the strip belt; Means for transferring the object delivered to the roller in the direction of rotation by the roller.

[0006]

In the object transfer device having the above-mentioned structure, by using the strip belt for the belt conveyor, the contact area between the object and the belt is reduced to reduce the influence of the adhesive force, and the roller is removed from between the strip belts. The object is lifted by projecting it relatively upward, the object is transferred from the belt to the roller, and is transferred in the rotation direction of the roller.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail based on the illustrated embodiments. FIG. 1 is a plan view of the embodiment, and FIG. 2 is a cross-sectional view. A belt conveyor 1 is provided with a plurality of strip belts 2 that move in the direction of arrow A. With these belts 2, for example, buns, etc. Object S is transported. Below the end of the belt 2, a row of small rollers, each row being composed of a plurality of small rollers 3, is provided in each gap of the strip belt 2.
Further, a roller base 5 equipped with a large roller row in which one row is composed of a plurality of large rollers 4 is installed so as to be movable in the vertical direction indicated by arrow B. The small roller 3 and the large roller 4 can rotate in a direction orthogonal to the moving direction of the belt conveyor 1.

In addition, each small roller 3 and large roller 4
Are attached to the roller base 5 so that their upper surfaces form the same plane, and the upper ends of the small rollers 3 are arranged to project from between the belts 2 when the roller base 5 is raised. Further, for example, a fluorine resin is applied or adhered on the surfaces of the small roller 3 and the large roller 4 in order to avoid adhesion with the object S.

An arm 6 is provided on the roller base 5 on the small roller 3 side.
The pushing mechanism 6 including a and a pressing portion 6b is installed, and the arm 6a and the pressing portion 6b are movable on the roller base 5 in the arrow C direction and rotatable in the arrow D direction.
A rotary table 7 of a packaging machine that is intermittently driven is installed on the roller base 5 side of the large roller 4, and the peripheral edge of the rotary table 7 is always rotated above the large roller 4. A plurality of object accommodating portions 8 are provided on the periphery of the rotary table 7, and slits 8a to 8 are formed on the bottom surface of each of the object accommodating portions 8.
d is formed. The slit 8a is wide, and the large roller 4 is vertically movable therein. When the roller base 5 is raised, the upper end of the large roller 4 is arranged to project slightly above the slit 8a. There is.

Further, a detector (not shown) for detecting the object S is installed on the belt conveyor 1, and a signal from the detector raises the roller base 5 and the arm 5a.
Is going down. The roller base 5
The power of the push-out mechanism 6 is transmitted from the driving means of the belt conveyor 1 via the cam mechanism.

With such a structure, when the object S is not on the roller base 5, the pressing portion 6b of the arm 6a is lifted and is moved on the belt conveyor 1 in synchronization with the intermittent drive of the rotary table 7. You are doing repetitive exercise. When the detector detects that the object S has been conveyed above the roller base 5, the roller base 5 rises and the small rollers 3 project from between the strip belts 2 of the belt conveyor 1 and S is transferred onto the small roller 3 and at the same time the arm 6
a, the pressing portion 6b descends. Then, the object S is the pressing portion 6
It is pushed out in the direction of the rotary table 7 by b, is rolled on the small roller 3 and the large roller 4, and is transferred into the accommodating portion 8 of the rotary table 7 as shown in FIG.

When the object S is transferred into the object container 8,
The roller table 5 descends as shown in FIG. 4, and the object S is placed on the object housing section 8. At the same time, the arm 6a and the pressing portion 6b
Is lifted and returned to its original position as shown in FIG. Further, when a new object S'is conveyed above the roller base 5, the arm 6a descends again, and the object S is transferred into the next object storage portion 8 as before.

In the embodiment, the object S is delivered by raising the roller base 5 without moving the strip belt 2 up and down. On the contrary, the strip belt 2 is lowered and delivered. You may. Further, if the small roller 3 and the large roller 4 are given a driving force, the pushing mechanism 6 can be omitted.

Further, the arm 6a of the pushing mechanism 6 is connected to the object S
The reason why the arm 6a is lowered and raised each time it is pushed is that it is a hindrance to the next object S'at the time of returning, but if there is no fear of this, it is not necessary to raise the arm 6a. .

[0015]

As described above, since the object transfer device according to the present invention uses the strip belt for the belt conveyor, the contact area between the object and the belt can be reduced and the influence of the adhesive force can be reduced. it can. Further, since the object is lifted by the rollers which move up and down between the belts and is rolled on the rollers after being separated from the belt, the object can be transferred with less influence of the adhesive force.
