Abstract

PURPOSE:To operate an auxiliary plate securely and safely by providing the auxiliary plate with a weight for pressing a text. CONSTITUTION:When an auxiliary plate 24 is lowered, the auxiliary plate 24 presses a text on a text supplying belt with a weight 31. When the text on the belt is not present, the text is supplied before a table and pressed against the back of the auxiliary plate 24, and a starter switch 38 is trod. With this, an actuator 26 operates to have an elevating shaft 25 raised to raise the auxiliary plate 24. Then, with operation of a motor 37 and a clutch brake 36, a supporting member 22 and the auxiliary plate 24 are returned before the table, and a pressing piece 42 comes in contact with a stop switch 41 to have the supporting member 22 stopped. At the same time, the actuator 26 operates to have the elevating shaft 25 lowered. This causes the auxiliary plate 24 to drop with its own weight, a when the pressing piece 22 comes into contact with a switch for releasing the brake 43, the brake is released, and the auxiliary plate is proceeded by the weight 31 to press the back of the supplied text.

Problems to be Solved by the Invention As described above, the conventional auxiliary plate driving device requires operations for lifting, retracting, and lowering the auxiliary plate when replenishing text.

An object of the present invention is to automate the operation of returning the auxiliary plate, thereby simplifying or automating the text replenishment work.

Means for Solving the Problems The present invention provides a rail body extending parallel to a text supply belt on a table of a text feeder, a fulcrum member provided movably along the rail body, and a fulcrum member attached to the fulcrum member. an arm that protrudes substantially laterally with respect to the rail body and is rotatable around an axis parallel to the rail body; and an arm provided at the tip of the arm that can push the text on the text supply belt; an auxiliary plate that can lift the main body upward; a lifting shaft that extends close to the rail body, is driven by an actuator such as an air cylinder, and can push the arm from below to lift the auxiliary plate; a weight that is connected to the fulcrum member via a string and pulls the fulcrum member forward along the rail body and pushes the text against the auxiliary plate; This is an auxiliary plate driving device for a text feeder, which has a motor with a clutch brake gear that can return and stop the auxiliary plate by pulling the auxiliary plate backward along the rail body.

In this device, it is necessary for the actuator and motor of the lifting shaft to operate at appropriate timings, so various configurations are available, such as providing a switch for each and operating it manually, or a sequencer linked to a timer. However, it is particularly convenient to use the following configuration.

That is, in the above device, there is a start switch that activates the actuator of the lifting shaft to lift the auxiliary plate, a return switch that detects that the lifting shaft has been raised and applies the rotational force of the motor, and a return switch that detects that the auxiliary plate has returned. detect,
A stop switch that stops the rotational force, activates a brake to stop the fulcrum member, and further activates the actuator to lower the lifting shaft, and a stop switch that detects that the auxiliary plate has lowered and releases the brake to release the auxiliary plate. It is preferable to provide a brake release switch that allows the user to press the main text.

EXAMPLES Below, examples illustrating the present invention will be specifically described.

In the auxiliary plate drive device 20 shown in FIG. 1, 21 is a rail body, which is made of one round bar and extends in the front and back direction parallel to the side of the text supply belt (not shown) on the table of the text feeder. It is set to stretch.

Reference numeral 22 denotes a fulcrum member, which fits into the rail body 21 and is movable along the rail body 21. Reference numeral 23 denotes an arm, which projects laterally from the fulcrum member 22, and whose base portion is rotatable relative to the fulcrum member 22 and can rotate around the rail body 22. Reference numeral 24 denotes an auxiliary plate, which is provided at the tip of the arm 23 and is capable of pushing the text on the text supply belt and lifting it onto the text. Reference numeral 25 denotes a lifting shaft, which extends adjacent to and parallel to the rail body 211C and can rotate around the rail body 21. 26 is an actuator, which is an air cylinder, is provided below the lifting shaft 25, is connected to the lifting shaft 25 via a link 27, raises the lifting shaft 25, pushes the arm 23 from below, and lifts the auxiliary plate 24. In addition, the lifting shaft 25 can be lowered to a position where the auxiliary plate 24 pushes the text. 28 is a string consisting of a chain, extending forward from the front end of the fulcrum member 22, that is, in the direction of movement of the text supply belt, reversed at the foil 29, and further directed downward at the foil 30, and a weight 31 is connected to the tip. has been done. Therefore, the weight 31 pulls the fulcrum member 22 forward, and the auxiliary plate 24 pushes the text. Reference numeral 32 designates another string, which is made of a string, extends rearward from the rear end of the fulcrum member 22, is reversed at a foil 33, and further directed downward at a foil 34, and has a small weight 35 connected to its tip. A motor 37 is connected to this wheel 34 via a clutch brake 36. Therefore, when the rotational force of the motor 37 acts, the fulcrum member 22 can be moved rearward, and when the brake of the clutch brake 36 is activated, the fulcrum member 22 can be moved backward. When the fulcrum member 22 can be stopped and the clutch or brake is released, the string 32
While applying tension with the small weight 35, the weight 31 is applied as described above.
can move the fulcrum member 22 forward.

38 is a starting switch, consisting of a 7-button switch,
When the operator steps on the actuator 2 of the lifting shaft 25
6 is activated to raise the auxiliary plate 24. 39 is a return switch, which is a push piece 4 provided on the actuator 26.
0 detects that the lifting shaft 25 has risen, and the rotational force of the motor 37 is applied to the clutch brake 36 to move the fulcrum member 22 rearward and return the auxiliary plate 24. 41 is a stop switch, which detects that the fulcrum member 22, that is, the auxiliary plate 24 has returned to the rear end of the table when the push piece 42 provided on the fulcrum member 22 comes into contact with it, and switches the clutch brake 36 to the motor 37.
The action of the rotational force is stopped, the brake is activated to stop the fulcrum member 22, and the actuator 26 is caused to lower the lifting shaft 25. 43 is a brake release switch, which detects that the arm 23 rotates when the pushing piece 44 provided at the base of the arm 23 comes into contact with it, and that the auxiliary plate 24 descends to the position where it presses the main body, and releases the clutch brake 36. Release the brake and allow the auxiliary plate 24 to push the text.

Since this drive device has the above configuration, it operates as follows.

When the auxiliary plate 24 is lowered as shown in the figure, the auxiliary plate 24 pushes the text on the text supply belt by the weight 31. When the text on the text supply belt becomes low, the text is supplied to the front (rear) of the table as in the past, and the auxiliary plate 24
, and then step on the start switch 38. When this happens, the actuator 26 is operated, the lifting shaft 25 is raised, and the auxiliary plate 24 is lifted. Next, the motor 37,
By the action of the clutch brake 36, the fulcrum member 22 and the auxiliary plate 24 are returned to the front of the table, and the push piece 42 comes into contact with the stop switch 41, and the fulcrum member 22 is stopped. At the same time, the actuator 26 is operated and the lifting shaft 25 is lowered. Therefore, the auxiliary plate 24 descends due to its own weight, and when the push piece 44 comes into contact with the brake release switch 43, the brake is released and the auxiliary plate 24 is moved forward by the weight 31 and pushes the back of the supplied text. Note that if the auxiliary plate 24 is returned and does not descend due to contact with the worker's hand, the brake is not released and the fulcrum member 22 remains at the stopped position 1, ensuring safety.

In the above embodiment, a foot switch is used as the starting switch 38, but a manual switch may also be used. Furthermore, if the main text is automatically refilled instead of manually (D) as described above, it goes without saying that a switch linked to this replenishing device can be used as a starting switch.

Effects of the Invention As described above, the auxiliary plate drive device of the present invention can automatically perform the work of returning the auxiliary plate when the text is supplied to the text feeder, thereby saving labor. . Since the force for pushing the auxiliary plate is applied by a weight as in the conventional case, a uniform force can be applied, and this force can be easily adjusted by changing the weight of the weight. Furthermore, since gravity is also used to lower the auxiliary plate, operation is reliable and safe.

Furthermore, in addition to the start switch, providing a return switch, stop switch, and brake release switch will ensure that each part operates in sequence, and even if an operation malfunctions for some reason, the next operation will not be triggered. do not have. In particular, the brake is released and the support member is moved only after the brake release switch detects that the auxiliary plate 24 has descended instead of the lifting shaft, so the auxiliary plate may hit the operator's hand. It is safe because the auxiliary plate does not start moving forward unless it descends.
