[Problem to be solved by the invention]

As shown below, in the conventional example, the workpiece 17 must be handled by a moving mechanism in the Z-axis direction according to its position, and for this purpose it is necessary to align the workpiece 17. If the position of the workpiece is shifted, it will cause problems in handling and cause trouble.Furthermore, if you want to grip workpieces 17 of different sizes, it is necessary to adjust the positioning of the workpiece 17, which reduces work efficiency. there were. Furthermore, since it has a large number of drive mechanisms, there is a problem in that the cost of the device is high.

This invention was made in order to solve the problems of the conventional method as described above.It eliminates positional deviation due to workpiece troubles, and eliminates the need for adjusting positioning when supplying workpieces of different sizes, increasing work efficiency. It is an object of the present invention to provide an inexpensive supply device which eliminates the need for an expensive positioning mechanism and handling mechanism, constitutes an in-cylinder transfer means, and a dispensing control means having a gate blockage prevention function.

(Means for Solving the Problem) Therefore, in the present invention, a transfer means A for transferring a plurality of workpieces in one direction, and a delivery control means B including a gate for distributing the workpieces. By equipping the dispensing control means B with a function to prevent the cage from being blocked by the workpiece in No. 111, the purpose of No. 11ff [1] is achieved.

(Function) In the feeding device of the present invention, the transfer means A transfers a plurality of works in one direction, and the delivery control means B having a gate blockage prevention function prevents the gates from being blocked by the works. The works are delivered one by one.

(Example) An embodiment of the present invention will be described below based on the drawings.

FIG. 1 is a plan view of a supply device which is an embodiment of the present invention;
Fig. 2 is a front view of Fig. 1, Fig. 3 is a side view of Fig. 1, Fig. 4 is a partial view showing the cage closed by a work, and Fig. 5
The figure is a partial view showing the operation of the gate blockage prevention mechanism in Figure 1.
FIG. 6 is a partial view showing the reverse rotation state of the gate blockage prevention mechanism shown in FIG. 5. In FIG. This is a bushing that is sent out onto the conhair 2, and is configured to move along two guides 7 (to the right in the figure). Reference numeral 2 denotes a transfer conveyor which is a transfer means A continuously driven in the X direction, and 3 a workpiece having the same shape as the workpiece 17 in the conventional example.

Next, 4.5 is a pair of gate blockage prevention mechanisms (hereinafter referred to as prevention mechanisms) constituting the delivery control means B, each of which delivers one workpiece 3 to the flow direction of the workpiece 3 (as indicated by the arrow). The transfer means A is formed by forming gates G at intervals that allow delivery.
It is arranged in an inclined V-shape on a transfer conveyor corresponding to . This prevention mechanism 4.5 includes a belt g, a pulley i1m driven by drive sources Ml and M2 (Fig. 3), respectively, and pulleys h and j driven respectively.
and It, n, and are mutually set at a predetermined angle, for example, 90° to 120°, as shown in FIG.
The gap between the prevention mechanisms 4 and 5, that is, the gap between pulley j and pulley n forms the gate G, and this gate G is connected to the workpiece 3 or 1.
The gate width is set to the extent that the gate can be freely passed through from one to another. Moreover, the prevention mechanisms 4.5 rotate in opposite directions,
Moreover, the mutual rotation direction changes after a desired time, so that the rotation direction can always be reversely rotated.

Note that 6 is a delivery conveyor that receives the workpiece 3 delivered by the delivery control means B and supplies it to the next process.

In the above configuration, the transfer means A is configured by the transfer conveyor 2 and is a means for transferring a plurality of works 3 in one direction, as in the case of multiplexing, and the delivery control means B is configured by the gate blockage prevention mechanism 4. 5 and a gate G, the workpieces 3 transferred by the transfer means A are arranged as desired on the carry-out conveyor 6 without being blocked (in this embodiment, in one row with a predetermined interval).
This is the first step.

Next, the operation of this embodiment will be explained with reference to FIGS. 1 to 6, focusing on the transfer means A and the distribution control means B.

In FIG. 1, a pallet 10 from the previous process (not shown)
A plurality of workpieces 3 carried in are pushed out by a pusher l to a transfer conveyor 2, which is a transfer means A, which is continuously driven in the X direction.

The pushed out workpiece 3 is transferred to a guarded area W formed between the anti-low mechanism 4.5, which is the delivery control means B. Eventually, the area W is filled with the workpieces 3, and the gate G is blocked (clogged) by the workpieces 3, making it impossible to transfer them. This state is shown in FIG. Therefore, as shown in FIG. 5, the belt k of the prevention mechanism 5 as well as the heald g of the prevention mechanism 4 rotate in opposite directions (in the direction of the arrow in FIG. 5).

By performing such mutually contradictory driving rotations, the workpiece 3 on one side of the prevention mechanism 5 is pushed back and held,
The work 3 on the other prevention mechanism 4 side passes through the gate G and is delivered to the carry-out conveyor 6''.

This operation continues until there is no more workpiece 3 placed on the prevention mechanism 4 side. Thereafter, each of the prevention mechanisms 4.5 is rotated in the opposite direction, and the workpiece 3 is delivered from the prevention mechanism 5 onto the carry-out conveyor 6, as shown in FIG. In this way, each of the mutually facing prevention mechanisms 4 and 5 reverses the forward and reverse rotation, so that the workpiece 3 flows smoothly onto the carry-out conveyor 6, and the workpiece 3 can be reliably supplied to the next process. .

In this embodiment, regardless of whether the workpieces 3 of the same size or different sizes are supplied, the workpieces on the pallet 10 may be placed at random positions, and there is no need for positioning adjustment. In addition, in this embodiment, the workpiece 3 is transferred to the unloading container 6.
Although the case of arranging in a row has been described, it is possible to arrange in multiple rows by increasing the number of prevention mechanisms, and by changing the rotation speed of the belt of the prevention mechanism 4.5 or the belt of the conveyor belt 6. , workpiece 3 on unloading conveyor 6
You can also adjust the spacing.
