Description

[Detailed Description of the Invention] Conventionally, a belt conveyor was used to feed objects from the perpendicular direction, diagonal direction, and upward direction to an endless sorting conveyor moving at a constant speed, and the conveyance was carried out directly or manually. Most of the feeding devices were designed to feed objects onto a tray, but they were not suitable as feeding devices for clothing or small items.

Furthermore, it is conventional to supply the conveyance to moving trays or via a supply conveyor.
When using a supply conveyor, for example, as shown by the imaginary lines in Figs. 1 and 2, the conveyor is placed on the belt of the supply conveyor so that when the tray of the sorting conveyor is positioned at the connection part of the supply conveyor, the conveyed items are supplied. The positions where the objects to be transported are placed are marked, and the objects are manually fed to the marked positions during movement, which puts a considerable burden on the workers.

In other words, in conventional feeding devices, a phototube is turned ON and OFF directly at the conveyed object in order to determine the timing with a tray, etc., but this detection method is difficult and costly for thin or small objects such as clothing. ing.

b. Most feeding conveyors are belt conveyors, so a forcing device is required to keep the objects in place.

c.Put it on a belt conveyor by hand,
In addition, placing objects directly on the tray while the object is being moved increases eye strain.

There were various drawbacks such as:

The present application was invented to eliminate these drawbacks, and the object is placed so as to straddle the triangular recess formed by two belts, and the object is moved naturally in the direction of travel by using the slope. On the other hand, by correcting the position to the normal position and opening the belt from the center to the left and right, it is made to fall to the center of the tray,
To ensure that objects to be transported, especially thin items of different sizes such as clothing and small items, fall at the center of the tray in the direction of travel, and to open the belt without moving left or right from the center. This is an invention related to an induction conveyor that aims to prevent the transported object from tilting or shifting due to friction because no slipping occurs between the transported object and the belt mounting surface. be.

To explain the embodiment now, a frame body 2 is formed with a square window 1 in the center for inputting goods to be transported, and a moving frame 4 is placed inside the front and rear edge frames 3 of the frame body 2 in front, rear, left and right directions.
In this arrangement, rollers 5 are fixed to the movable frame 4 so as to connect the front and rear movable frames 4 on the left and right sides, and one roller 5 is provided at each end of the movable frame 4.

Further, one end of a belt 6 wider than the front and rear widths of the window part 1 is fixed to the lower part of the left and right edges of the window part 1, and the belt 6 is
From the upper part of the roller 5 on the center side of the window part 1, the roller 5 descends from the outside, passes through the lower part, and is located on the outside.
A spring 7 is attached to an end portion of the belt 7 which extends upwardly from the lower part thereof, and the other end of the spring 7 is attached to the location where the belt 6 is attached to form a conveyed object receiving member F.

A support plate 8 is attached to the movable frame 4 facing outward, and the tip of a piston rod 10 of an air cylinder 9 is attached to the support plate 8, so that the air cylinder 9 is fixed to the side surface of the frame body 2. Further, the roller 5 is installed using a small diameter roller 5 so as to be located below the horizontal center line of the frame body 2.

Furthermore, when the piston rod 10 is fully extended, the rollers 5 located inside the window 1 come into contact with each other, and the left and right belts 6 contact each other, so that the center of the window 1 is closed.

Furthermore, when the rollers 5 located inside the window 1 are close to each other, the left and right belts 6 are designed and manufactured to form an inverted triangular recess G at the window 1. The object receiving member F thus formed is attached to the upper surface of the main body E' of the object mounting table E, and the parts other than the window 1 are covered with a decorative board E'' to form the entire object mounting table E.

To explain the operation of the induction conveyor having the above structure, the piston rod 10 is extended and the left and right belts 6 are brought into contact with the lower part of the window part 1 to close the center part of the window part 1. An inverted triangular recess G is formed, and when the transported object A is placed in the recess G, the belt 6 is inclined so as to descend from the left and right toward the center, so even if the transported object A is placed on one side. The side with the most passengers (the side with the highest number of passengers) descends along the slope, and the other side rises, using the slope to move the object A to the center of the window 1 and perpendicular to the direction of travel. When the desired tray C is right under the window 1, actuate the cylinder 9 to move the piston rod 10 into the cylinder 9.
When pulled in, the moving frame 4 moves left and right, so the belt 6 is also wound up at the same time, and the belt 6 on the window 1 side
is pulled in to the left and right, and the center side opens to the left and right to open the window 1, so that the carried object A falls into the center of the tray C. Thereafter, the piston rod 10 is extended again by the action of the cylinder 9, the movable frame 4 is moved, the window 1 is closed, and the next article A is loaded.

When the cylinder 9 is actuated and the movable frame 4 moves to open the window 1, the belt 6 does not rotate or move, and the movable frame 4 moves left and right while the roller 5 rotates to open the window. , so that "slip" does not occur between the transported object A and the mounting surface of the belt 6 on which the transported object is placed.

Therefore, when the window portion 1 opens, the conveyed article A is not tilted or displaced due to friction between the conveyed article A and the belt 6, and the predetermined position on the tray running on the conveyed article A is prevented. It can be dropped exactly in place.

Then, this conveyed article mounting table E is placed on the tray C at a desired location on the sorting conveyor D, which has a tray C installed on the upper part.
They are installed in several locations so that they pass through the bottom of the window.

According to the above-mentioned configuration, the present application places the transported object A on the transported object receiving member F formed by the belt 6, and when the desired tray C comes to the lower part of the transported object A, the cylinder 9 is actuated to move the moving frame 4 in the left and right direction. , open the belt 6 to the left and right, open the center, and place the transported object A on the tray C.
When the object A is dropped upward, the cylinder 9 is activated to close the window 1 and prepare for the next object A to be loaded.

The operation of the cylinder 9 is such that when the desired tray C comes to the lower part of the desired window section 1, the tray C or the conveyed object A is detected by an electric light tube or the like, and the air which operates the cylinder 9 is activated. The circuit of the air supply device is transmitted to activate the cylinder 9, but the method of detecting this activation and the method of closing the electric circuit for activation of the cylinder 9 depend on the arrangement of the sorting conveyor D and the conveyed items. Depending on the mounting location, the design may be appropriately selected and configured, and any one may be used.

As mentioned above, the present application forms a frame body with a window in the center for inserting objects, and provides four moving frames inside the front and rear edge frames of the frame body, so that it can be moved back and forth on the left and right sides. One small-diameter roller is fixed to each end of the moving frame so as to connect the frames, and the rollers are installed so that they are positioned below the horizontal center line of the frame, and the window section is installed at the bottom of the left and right edges of the window section. Fix one end of a belt wider than the front and rear widths of the belt, lower the outer side from the upper part of the roller on the center side of the window part, pass through the lower part, and raise the outer side from the lower part of the roller located on the outer side. , attaching a spring to the end, attaching the other end of the spring to the location where the belt is attached, further attaching a support plate facing outward to the moving frame, and attaching the tip of the piston rod of the air cylinder to the support plate; When the air cylinder is fixed to the side of the frame and the rollers located inside the window are close to each other, the left and right belts form an inverted triangular recess at the window to transport the object. A receiving member is formed, the object receiving member is attached to the upper surface of the main body of the object mounting table, and the parts other than the window are covered with a decorative board. The conveyed object is corrected so that it is placed in the recess at a right angle to the direction of travel, and since the belt opens from the center to the left and right, it can fall to the center of the tray located directly below in the direction of travel. Since the conveyed object always passes through the central abutting part of the shaped recess, it can be detected accurately with an electric light tube, etc., so there is no need to arrange and detect a large number of electric light tubes as in the past. When opening the window, the moving frame moves left and right while the roller rotates and the belt does not rotate or move to form the opening, so that the transported object and the transported object can be placed. There will be no "slip" between the belt and the mounting surface of the belt. Therefore, when the window opens, the transported object is accurately dropped into a predetermined position on the traveling tray without the transported object being tilted or displaced due to friction between the transported object and the belt. It has the following effects:
