Description

The present invention relates to a press product separator that separates a product and a skeleton that are integrally transported from a blanking press processing step, and that automatically sorts a product, a skeleton, and a defective product.

When punching a plate product by a blanking press, for the convenience of the manufacturing process, a process for integrating the product and the skeleton is performed so as not to be separated after the processing. That is, in the blanking press, since the mechanical connection between the product and the skeleton is cut off, a process of lightly fitting both of them immediately after blanking is performed, and the integration is maintained by the frictional force of the contact surfaces. For example, according to Japanese Patent Laid-Open No. 9-94797, when a plurality of products are processed from a large plate, a method of automatically separating a product and a skeleton by a tensile deformation by a clamp method of a skeleton part or an impact caused by a drop is a conventional method. Known from.

However, in the case of separation where a workpiece in which the product and the skeleton are integrated by a slight fitting is sequentially supplied at regular intervals and one workpiece is processed per workpiece, the worker must It is known from a separating apparatus that requires a work that shakes a work up and down, right and left, or gives a vibration, or is supported by a hand, for example, Japanese Patent Application Laid-Open No. 2002-59222, both of which involve an operator.
JP-A-9-94797 JP 2002-59222 A

Separation and sorting of the fitted items by manual work is a full-time work, which is heavy labor, has poor work efficiency, may cause scratches and distortions, and requires a large work space. In order to improve this load work, full automation is required, but for that purpose, the positional relationship between the product part and the skeleton part of the workpiece that are sequentially supplied at regular intervals is accurately grasped, and scratches and distortion are generated. It is necessary to separate the fitting portion without causing it to be performed and to automatically perform separation after separation.

The present invention is intended to solve the problems of such a conventional configuration, eliminates the burden on the operator, makes it possible to easily position the workpiece, and removes scratches and distortions by separation. It is an object of the present invention to provide a press product separator capable of separating a fitting portion without causing occurrence and further automating sorting after separation.

The present invention is a press product separator for achieving the above object, and has the following configuration. A striking device that separates the product and the skeleton by applying vibration to the workpiece in a state where the product and the skeleton after pressing are integrated by slight fitting, and the separated product or skeleton on the downstream side of the striking device. Openable and closable gate that temporarily stops the larger object, multiple stops that can be sorted and sorted according to the flow direction of the object flowing down and downstream of the gate, and multiple chutes This is a press product separator characterized by the above.

Further, according to the present invention, a plurality of stoppers are installed so as to be inclined in directions opposite to each other with respect to the flow direction, and can be freely projected and retracted with respect to the chute surface. It is a press product separator characterized in that it is configured to discriminate the state of an object temporarily stopped, and to project one stopper based on the discrimination result and to sort the objects that flow down by opening the gate. .

As described above, the press product separator of the present invention automatically separates the slight fitting applied to the workpieces that are sequentially supplied at regular intervals without causing scratches or distortion, and after the separation. It is possible to provide a press product separator that eliminates the burden of separation work by automatically sorting products, skeletons, and defective separation products without the intervention of an operator.

Further, since the separation of the fitting is performed in a generally sealed space having a cover, the effect of further reducing noise is exhibited.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.

FIG. 1 is a perspective view showing a configuration example of a press product separator provided with a separation mechanism and a sorting mechanism of the present invention. 2 is an explanatory view showing a slight fitting between the product P and the skeleton S applied to the work W, FIG. 3 is an AA cross-sectional explanatory view of FIG. 2, and FIG. 4 is a perspective view showing a state of the work loading and positioning. 5 is a cross-sectional explanatory view taken along the line BB of FIG. 4 showing the separation mode, FIG. 6 is a plan view showing the state of arrangement of the sorting and sorting chutes, and FIGS. 7 to 9 are perspective views showing the working mode of the sorting.

Hereinafter, a basic structure of a press product separator according to an embodiment of the present invention will be described with reference to the drawings.

According to FIG. 1, a separation mechanism having a workpiece feeding device 1 as a workpiece loading device of the main body as a base is arranged. In addition, the longitudinal direction of the workpiece feeding apparatus 1 is indicated by an arrow in the drawing.
A striking device 2 and a metal fitting 3 for separating the light fitting between the product P and the skeleton S are arranged in parallel at the substantially central portion in the X-axis direction of the workpiece feeding device 1 having the endless structure.

A sorting mechanism that is inclined downward in the vertical direction of the X-axis through a very small gap from the leading end of the workpiece feeding device 1 is disposed. This sorting mechanism has a main chute 18 located in the center as a base, and an openable / closable gate 14 for temporarily stopping a larger object in the product P and the skeleton S on the upstream side, and a downstream side of the gate 14. The stopper 4 and the stopper 5 for distributing the flow of the flowing object to the left and right with respect to the X-axis direction, the chute 19 and chute 20 for allowing the distributed object to flow down, and the detector 17 that can determine the separation state of the object. And the detector 21.

The operation | movement aspect of the separation apparatus concerning a present Example is demonstrated using FIGS. In the present embodiment, a case where the larger object is the skeleton S and the smaller object is the product P will be described as an example of the work configuration.

The work W, which is slightly fitted between the product P and the skeleton S by the press machine installed adjacent to the press product separator of the present invention, is spaced from the upstream side of the work feeding apparatus 1 by a certain distance. Sequentially supplied.

2 and 3 show a state in which the product P and the skeleton S, which have been disconnected mechanically, are slightly fitted and integrated by punching by a blanking press. The inner diameter of the skeleton S, which is the larger object, and the outer diameter of the product P, which is the smaller object, mesh with each other and are supported so as not to be separated by the frictional force of the fitting portion N.

Referring to FIG. 4, the workpiece W carried in from the upstream side of the workpiece feeding device 1 (indicated by the arrow X) is punched by the hitting device 2 by the action of the entry side guide 6 installed by supporting two frames. It is positioned in an appropriate state so as to abut on. That is, the adjustment switch 7 moves the skeleton portion of the workpiece W to the punch position of the striking device 2 accurately and easily by the screw rotating through the motor and the V-belt and the adjustment handle 8 capable of fine adjustment of the rotation. is there.

The workpiece W positioned at an appropriate position on the workpiece feeding device 1 exits the entry side guide 6, is transported to the striking device 2 by the support of the workpiece feeding device 1, and is a detector disposed immediately before the striking device 2. 9 and is moved directly below the punch 10.

The time interval from the detection of the detector 9 to the operation of the striking cylinder 11 can be freely set, and the striking cylinder 11 is an integral type supported by a U-shaped bracket via a linear rail (not shown). It has a structure, and the height can be set freely with the adjustment handle 12 disposed above.

The striking cylinder 11 is formed by increasing the stroke speed, thereby enabling a high-speed striking, realizing separation by vibration rather than bending in the vertical direction, and preventing the product P from being distorted after separation. Is.

As shown in FIG. 5, in the properly positioned workpiece W, by hitting the skeleton S in the vicinity of the fitting portion N, the fitting is disconnected and the product P is separated from the skeleton S. become.

That is, when the punch 10 arranged at the lower end of the striking cylinder 11 strikes the skeleton portion, the striking portion is struck down, and the striking portion opposite to the striking portion of the skeleton S jumps upward with the edge of the work feeding device 1 as a fulcrum. Raised. The splashed skeleton S collides with the metal fitting 3 provided in parallel with the punch 10 in the direction perpendicular to the X axis and gives even vibration to the entire workpiece W to enable separation. The action by this seesaw mechanism is achieved by the proper positional relationship between the fulcrum, the punch 10 and the metal fitting 3, and the action of the impact cylinder 10 at a high speed.

In addition, since the space in which the separation mechanism is disposed is normally covered with a cover (not shown) in a substantially sealed state, generation of noise due to impact can be prevented.

In this way, the product P can be separated with low noise without causing scratches or distortion, and can be easily automated.

Referring to FIG. 6, the product P and the skeleton S that are unloaded from the separation mechanism and loaded into the sorting mechanism, or the work W that is kept in a fitted state due to a poor separation state, is connected to the gate opening / closing cylinder 13 and the gate 14. It passes through the exit guide 15 provided.

The exit guide 15 is provided with gates 14 on the left and right sides of the lower side through a slide bar constructed by supporting two frames. The gate 14 is attached between the frames at equal intervals on the left and right, and screw rods installed in parallel with the slide bar are connected to each other, and the opening interval is adjusted by the adjustment handle 16. The screw rod consists of a right screw and a left screw with the center as a boundary, and the opening interval between the gates 14 is adjusted by operating the adjustment handle 16. A detector 17 that detects the arrival of the product P, the skeleton S, and the defective separation product at the gate 14 is disposed in the vicinity of the downstream side of the gates 14.

The gate 14 is a rectangular plate standing vertically to the longitudinal direction of the main chute 18, and has fulcrums 22 and 23 at the upper end thereof, and the lower end is supported by a gate opening / closing cylinder 13 integrated with the outlet guide 15. The left and right gates 14 have a structure that can be opened and closed like a double door.

In the middle of the main chute 18 downstream of the gate 14 in the X-axis direction, a sorting device consisting of the stopper 4 and the stopper 5 is arranged. A chute 19 on the right side in the horizontal direction and a chute 20 on the left side in the horizontal direction from that point. Further, a detector 21 is provided downstream thereof.

According to FIG. 7, the product P and the skeleton S carried out from the separation mechanism are already separated, and the product P is freely arranged on the skeleton S in an unsupported state, and the main chute 18 is in a state where they overlap each other. It is carried in. Furthermore, it flows down to the exit side guide 15 provided on the entrance side of the main chute 18 and reaches between the gates 14 arranged opposite to the left and right. Here, it is detected that the product P and the skeleton S have reached the gate 14 by a detector 17 provided downstream between the opposing gates 14.

The skeleton S is prevented from flowing in the left and right gates 14 and 14 which are adjusted to a position interval smaller than the outer diameter of the skeleton S and larger than the outer diameter of the product P. However, the product P having an outer diameter smaller than the interval between the gates 14 passes between the left and right gates 14 and flows down on the main chute 18 using the inclination of the main chute 18 and the weight of the product P.

A detector 21 is provided at a point past the middle of the main chute 18 and is detected by the detector 21 when the product P passes there. It is determined that the fitting of the product P and the skeleton S is properly separated when the two conditions of detection by the detector 17 and the detector 21 are satisfied.

Referring to FIG. 8, in this condition, a stopper 4 that is inclined to the chute 19 side and that can protrude and retract in a direction perpendicular to the main chute 18 surface supports this from the rear surface of the main chute 18. It protrudes by the action of the cylinder (not shown).

Next, the gate opening / closing cylinder 13 integrated with the exit guide 15 and connected to the gate 14 operates almost simultaneously with the protrusion of the stopper 4 described above, and the gates 14 facing left and right move away from each other, and the door is opened. Increase the distance between the two as if open. As a result, the skeleton S that has been blocked from passing down flows, contacts the stopper 4, is switched to the chute 19 side, and flows down to the chute 19.

With the above configuration, the product P and the skeleton S are sorted. However, there may be cases where defective separation occurs, and the case where it is carried into the sorting mechanism will be described with reference to FIG.

The poorly separated product is prevented from flowing down by the gate 14 in the same manner as the restraint of the skeleton S, and the arrival at the gate 14 is detected by the detector 17, but the product P and the skeleton S are not separated. Without being detected by the detector 21 provided downstream from the middle of the main chute 18.

It is determined that a defective separation product has been carried in at the stage where two conditions of detection by the detector 17 and non-detection of the passage of the product P by the detector 21 after a lapse of a specific time are satisfied.

Under this condition, a cylinder (not shown) that is arranged to be inclined toward the chute 20 and that supports the stopper 5 from the back surface of the main chute 18 is supported by a stopper 5 that can be raised and lowered in a direction perpendicular to the main chute 18 surface. Protrusions by the action of.

Next, the gate opening / closing cylinder 13 integrated with the outlet guide 15 and connected to the gate 14 operates almost simultaneously with the protrusion of the stopper 5, and the gates 14 facing left and right move away from each other to open the door. Increase the distance between the two as if. The poorly separated product that has been blocked from passing down flows into contact with the stopper 5, the path is switched to the chute 20 side, and flows down to the chute 20.

The press product separator of the present invention can also be applied to separation and sorting of plate products that have been processed into product shapes while leaving fine connections to the plate materials, that is, microjoint processed products. The same effect is demonstrated.
