Abstract

PURPOSE:To improve conveying performance and stopping performance, prevent collision and relieve a shock at the time of stoppage by providing a number of driving members consisting of a motor and a rotor at an appropriate interval along conveying rails and individually controlling the driving members. CONSTITUTION:By driving the motor 8 of each driving member (a), conveying bodies 1 are moved along rails 2 while being stopped by the stoppage of the motor 8. In this case, the driving members (a) are individually controlled in their driving/stoppage and in their speed to effect local acceleration/deceleration and the function of a stopper at the time of stopping. By this structure, conveying performance and stopping performance can be improved, preventing collision while relieving a shock at the time of stoppage.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a linear feed mechanism, and more particularly to a feed device that is suitable for use in conveyance equipment and is capable of stopping, moving, etc. a conveyor. It is something.

(Prior art) The purpose of all conventional conveyance technologies is to continuously feed the conveyor in a predetermined direction, so in order to use this in automatic assembly equipment, a stop device that stops the conveyor, a conveyor It was an essential condition to provide a body positioning device. In addition, there has been a significant demand for faster productivity recently, and therefore transportation.

IJ near motors have also been developed in view of faster positioning and higher accuracy.

(Problem to be Solved by the Invention) According to the former technique, a stopping device for stopping the carrier and a positioning device for the carrier are required.

Furthermore, the conveyance speed can be increased to accommodate higher speeds.

There is also the problem of impact force when stopping, and when restarting after stopping, the start-up speed is slow, so there is a limit to how high the speed can be increased, and when using a device that uses a linear motor like the latter, the price is 1. The drawback is that it is too expensive compared to conventional conveying devices.

This invention effectively utilizes the characteristics of the motor to improve transport, stop the transport, cushion shocks when stopped, prevent collisions between transport This invention relates to a feeding device that is also capable of stopping at a fixed position.

(Means for Solving the Problems) This invention provides a rail that regulates the moving direction of a carrier, a carrier whose movement is regulated by the rail, and a large number of drive units including motors and rotors that move along the rail. This is because they are placed at appropriate intervals.

By controlling this drive motor respectively.

This makes it possible to move and stop the conveyor.

(Function) The present invention configured as described above achieves partial speed increase by appropriately arranging drive monitors and controlling each individual motor.

It is possible to decelerate, move not only in one direction but also in the opposite direction, prevent collisions between conveyors, and use a rotating body such as a pole bearing in the walking part of the fM conveyor. This makes it easy to select parts that have extremely low wear, as well as parts and shapes that are hard to wear for the transmission parts installed on rails and conveyors, and the rotor that provides force to the transmission parts. Suitable for low-noise equipment and assembly equipment for products that are sensitive to shock.

The figure is a cross-sectional enlarged view of FIG. 1, in which (1) is a conveyor such as a pallet. (2) is a pair of left and right rails set on the floor, and in order to make the movement of the conveyor (1) smooth, it is equipped with a pole bearing such as a pole bearing attached to the bottom of the conveyor (1) with a spindle (3). A small rotating body (4) is placed on the rail (1) as a roller, and at the same time, an induction rotor (5) with low wear such as a ball bearing is mounted on a support shaft (5) so as to sandwich the sides of the rail (1) from both sides. 6) to the lower part of the carrier (1).

(7) is a transmission body fixed to the side surface of the conveyor (1), and the drive unit (a) consisting of a rotor (10) attached to the rotating shaft (9) of the motor (8) is connected to the rotor (10). ) are arranged on the rail (2) at appropriate intervals so that the transmitting body (7) comes into pressure contact with the transmitting body (7) of the carrier (1). Since this drive section (a) is individually controlled to move and stop the conveyor (1), the transmitter (7) is used as a rack and the rotor (10) is used as a binoculars. It may be configured to match.

With this configuration, the motor (8) of the drive unit (a)
By starting the conveyor (1) the rail (2) KG
by stopping the motor (8).

The carrier (1) stops. Therefore, the transmitter (7)
can be replaced by the carrier (1) itself.

In addition, by controlling the rotational speed of these motors (8), the feed speed can be partially increased or decreased, and by controlling the stop position, the stopper function for stopping the conveyor (1) can be adjusted. It is also possible to have one.

The examples shown in FIGS. 3 and 4 are those shown in FIG.

The configuration of the walking part of the conveyor is different from that in FIG. 2.

The transport body (11) is not provided with a rotating body, and the transport body (11) has horizontal support shafts (13) arranged on each inner surface of the frame (12).
It is placed on a "ball bearing" shaped rotating body (14) provided above, and a support shaft (
The moving direction of the carrier (11) is regulated by a smoothly rotating rotor (16) such as a ball bearing provided in the carrier (15), and the carrier (11) is driven by a motor as in the above case. The drive unit (a) consisting of the rotor (20) attached to the rotating shaft (19) of (18) is connected to the frame (
12), and its rotor (20) is installed in the carrier (11).
A concave groove (2
This rotor (20) is pressed against the inner wall surface of
The conveying body (11) may be advanced by pressure contact force, but in order to make the conveyance more reliable, teeth are carved around the first rotor (20) to form a pinion, and grooves ( 21) Also carve teeth into the inner surface to form a rack shape,
This may be meshed with a rotor (20) which is a binion.

Further, in the embodiment shown in FIG. 5, the rotor (
30) and the carrier (31) are set at different angles so that the contact is diagonal, and the component of the propulsive force acting in the direction of travel is used to move the carrier (31) downward so that it does not float up while in progress. The rotor (30) and the conveyor (31) with which it comes into contact can be carved with teeth, respectively.

(Effects of the Invention) Since the present invention is configured as described above, if the characteristics of the motor of the drive unit (a) are effectively utilized, the stopping device and buffer This eliminates the need for any attached devices such as accelerating or decelerating devices, allowing for highly clean and quiet transfer.In addition, by controlling the motor of the specific drive unit (a), the conveyor can be moved as desired. Because it can be positioned at the position of

It is an extremely effective device as it has the effect of reducing the degree of flexibility required for automatic assembly machines.
