Abstract

PURPOSE:To simplify a changeover selection operation means for switching an operation under manual condition to operation under a continuous condition and also under both conditions in a hanger conveying machine capable of making operation under both the manual condition during which sewing operation is carried out and the continuous condition during which the operation is not carried out. CONSTITUTION:Under a manual condition, a working arm can move to an intermediate position at which a hanger is received from a lower rail, a lower position at which operation is carried out and an upper position at which the hanger is delivered to an upper rail, meanwhile under a continuous condition, the working arm is set so as to deliver the hanger from the lower rail to the upper rail by moving to both intermediate position and the upper position. Furthermore, when operation time of a starting switch can be limited within a prescribed time, it is used as a starting signal under the manual condition, and when the operation time is longer than the prescribed time, it is used as a changeover signal to both conditions.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanger carrier for loading and unloading a workpiece or clothes to a sewing work position or finishing work position in a sewing factory or the like. And a control device for the hanger carrier.

[0002]

2. Description of the Related Art In a hanger carrier as shown in FIG. 3, reference numeral 1 is a first rail (lower rail) for carrying a hanging-type hanger 2 to be described later into a sewing work position.
Reference numeral 3 is a second rail (upper rail) which is located above the lower rail 1 and which carries the hanger 2 out of the sewing work position and into the next work position. The upper and lower rails are arranged so as to be inclined so that the hanger 2 can slide down by its own weight. The suspension type hanger 2 has two rails 1 and 3
A roller 4 suspended above is provided at the upper end, and a holding body 5 for holding a sewing object or the like is provided at the lower end.

Reference numeral 6 is a working arm having a rail portion 6A on which the roller 4 of the hanger 2 can be suspended.
Is connected to the lower rail 1 at an intermediate position, the rail portion 6A is connected to the upper rail 3 at an upper position, and
It is possible to move up and down to a lower position where the material to be sewn can be taken in and out of the holding body 5. Reference numeral 7 is a cylinder (driving means) for moving the working arm 6 up and down to the above three positions. Reference numeral 8 denotes a stopper arranged at the terminal end of the lower rail 1, which is retracted and retracted in the path of the roller 4 by the action of the cylinder (first action means) 9 so that the hanger 2 can be stopped or released. 10 is a roller 4
Is a locking body provided on the working arm 4 so as to be held on the working arm 6 by being engaged with, and the locking body 10 appears and disappears in the path of the roller 4 depending on the action of the cylinder (second working means) 11. Can be held or released. SW1 to SW6 are limit switches for detecting the moving position of the roller 4 or the rail portion 6A of the working arm 6, SW1 is the movement of the roller 4 onto the rail portion 6A, and SW2 is the lower position of the rail portion 6A. , SW3 moves the rail 6A to the upper position, SW4 moves the roller 4 to the upper rail 3, SW5
Is for detecting the movement of the rail portion 6A to the intermediate position, and SW6 is for detecting the movement of the roller 4 to the stopper 8 arrangement position.

In the hanger carrier described above, operation control as shown in FIG. 4 has been performed. That is, when the roller 4 (hanger 2) is placed on the working arm 6 and positioned at the lower position, the following operation is performed according to the control of one of the continuous state and the manual state selected by the operation of the mode selection switch (not shown). The operation of. For example, in the manual state, the operating arm 4 is raised to the upper position by the ON operation of the start switch, and when the locking body 10 is inactivated, the hanger 2 moves to the upper rail 3 and moves on the upper rail 3 to the next position. Freely slide down to the working position. Subsequently, the working arm 4 descends to the intermediate position, receives the new hanger 2, and descends to the lower position. And when the operator turns on the start switch,
The same operation as above is performed.

On the other hand, when the continuous state is selected, the start switch is not turned on at the lower position, but the lower rail 3, the upper position and the intermediate position are continuously moved to move from the lower rail 3 to the upper rail 3. Move hanger 2

[0006]

As described above, in the continuous state, the operation of the working arm 4 is sequentially moved to the three positions as in the manual state by simply eliminating the operation of the start switch. However, there is a drawback that work efficiency is significantly reduced. Further, as described above, since the mode selection switch for selecting the mode and the starting switch for starting are separately provided, there are disadvantages such as an increase in the number of parts and an increase in cost.

[0007]

[Means for Solving the Problems] A first rail for supplying a hanging hanger to a working position, and a second rail which is located above the first rail and carries out the hanger from the working position. In the working position, the first rail and the second rail are vertically movable to an intermediate position continuous with the first rail, an upper position continuous with the second rail, and a lower position for attaching and detaching a workpiece to and from the hanger. Between the working arm capable of supporting the hanger so that it can be delivered and received, a detection means for detecting the moving position of the working arm and the moving position of the hanger, and a driving means capable of moving the working arm to each position. This can be achieved by the hanger carrier that has the following configurations.

[0008] Selection means for selecting a manual state where work is performed and a continuous state where work is not performed at the work position, and the working arm is set to an intermediate position, a lower position and an upper position when the manual state is selected. And a control circuit for controlling the driving means so as to move up and down sequentially and, when selecting the continuous state, for controlling the driving means so as to move up and down the operating arm continuously between the intermediate position and the upper position. .

[0009] Selection means for selecting a manual state in which the work is performed at the work position and a continuous state in which no work is performed, a start-up means for generating a start signal by an operation, and a start signal when the manual state is selected. The driving means is controlled so as to sequentially move up and down the working arm to the intermediate position, the lower position and the upper position and then stop, and when the continuous state is selected, the movement of the hanger to the working arm is controlled. And a control circuit for controlling the driving means so that the working arm is continuously moved up and down between the intermediate position and the upper position by being driven by the detection.

Signal control means, and when the manual state is selected, the drive means is driven by a start signal to sequentially move up and down the working arm to an intermediate position, a lower position, and an upper position, and then to stop the driving means. When selecting the state, a control circuit for controlling the drive means is driven by detecting the movement of the hanger to the working arm and sequentially moves the working arm up and down between the intermediate position and the upper position. To be provided.

[0011]

When the continuous state is selected, the working arm is moved to the intermediate position and the upper position without moving to the lower position. A selection signal for selecting a mode is generated when the activation means is operated for a predetermined time or longer, and a activation signal is generated when the activation means is within the predetermined time.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENT In FIG. 1, a timer triggered by actuation of an activation switch produces a signal having a set time of time T. When the operation time t is longer than the set time T, the determination circuit for inputting the signal of the timer and the start switch makes one state control circuit which is currently valid invalid and the other valid, so that the time t is longer than the time T. When is shorter, it becomes a start signal in the manual state control circuit and is ignored in the continuous state control circuit. Limit switch SW1
And SW3 to SW6 are input to the manual state control circuit and the continuous state control circuit, but the limit switch SW2 for detecting the lower position of the working arm 4 is not input to the continuous state control circuit.

The manual state control circuit performs the same operation control as the conventional manual state operation as shown on the left side of the flowchart of FIG. When the activation switch is turned on when the working arm 4 is located at the lower position, the operation time is determined by the determination circuit, and when the operation time is longer than the set time T, the continuous state control circuit is enabled and the operation time is set longer than the set time T. When it is short, it becomes a start signal.

The continuous state control circuit is enabled by the discrimination of the discrimination circuit and processes the right side of the flowchart of FIG. In the continuous state, the cylinder 7 (driving means) is controlled so that the working arm 4 moves between the upper position and the intermediate position,
Hand over the hanger 2 between both positions. When the start switch is turned on in the continuous state, the operating arm 4 is returned to the manual state when t is longer than T by comparing the length of the operating time t with the set time T of the timer as described above, and the working arm 4 is moved. Stop moving to the lower position.

[0015]

[Effect] As described above, in the manual state, after the working arm receives the hanger from the lower rail at the intermediate position, it can be moved to the lower position and the upper position to perform the work, and then the upper rail can be transferred. Also, in the continuous state, after the working arm receives the hanger from the lower rail at the intermediate position, it moves to the upper position and shifts to the upper rail.
In a continuous state where no work is performed, the work efficiency is improved by not moving to the lower position, and when the operation time of the start switch is less than the predetermined time, it is a start signal in the manual state, and when it is more than the predetermined time, it is a manual signal. Since the signal is used as the switching selection signal for switching between the continuous mode and the continuous mode, the switch configuration is simplified, and the number of parts can be reduced and the cost can be reduced.
