Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a product accommodating device for accommodating, in a container, products that are sequentially discharged from a product discharging unit such as an automatic machine.

[0002]

[Prior art]

 Conventionally, as a method for storing and storing the products sequentially discharged from the product discharging section of an automatic machine, the products are dropped into the receiving box as they are, or a weir is provided in the middle of transferring the products by a belt and the products are placed there. For example, it has a buffer function to hold the product, and the robot transports the products one by one to a predetermined position.

[0003]

[Problems to be solved by the device]

 However, when a soft material such as gun metal is continuously processed by an automatic machine, the product is likely to be damaged after the processing is completed, and therefore the operator needs to be careful in handling the product. That is, among the above-mentioned conventional methods, the method of (1) is generally used and often used, but in this case, it cannot be adopted because it damages the product, and the method of (2) is merely a convenience. Not suitable for storing large amounts of product. The method (1) is preferable because it can realize desired product handling, but the equipment cost is enormous, and it is usually difficult from the economical point of view. Therefore, as in the case of processing general steel materials, there is a demand to keep the product fully filled with the product by continuously operating the automatic machine for a long time, and saving the labor of the operator during that time.

Therefore, the present invention is to provide a device for storing products sequentially discharged from a product discharge unit such as an automatic machine in a container with a simple structure so as not to damage the product. It is a specific subject.

[0005]

[Means for Solving the Problems]

 To this end, the following product storage device was created. That is, the present invention is a product accommodating device for accommodating products sequentially discharged from a product discharging part such as an automatic machine, which has a product mounting surface set at a position lower than the discharging part, Between the container and the container, which is driven and driven to intermittently rotate substantially horizontally, and one end of which can be moved toward and away from the product mounting surface of the container so as to move the product from the container to the container. A chute that guides to, a gate that is provided on the chute and that can open and close the chute, a sensor that detects a product at a position in front of the gate of the chute, and a sensor that is connected to the sensor and that detects a product A control mechanism for opening and closing the gate at a timing is provided.

[0006]

[Action]

 The products that are sequentially discharged from the product discharge part of the automatic machine slide down in the chute toward the container and are detected by the sensor when passing the position in front of the gate. The gate on the chute is closed at this time, and the product collides with the gate and stops. Subsequently, when the control mechanism is activated and the gate is opened, the product gently slides down into the container from a position close to the product mounting surface. Since this container intermittently rotates approximately horizontally, it is difficult for the products to pile up and they are stored in a level condition. After the product mounting surface of the container is almost completely filled with the product, the rear end of the chute comes into contact with the product and is lifted, so that the product is accommodated in a multi-layered state.

【Example】

 An embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, a vertical axis of a motor 3 (also referred to as a driving device) is provided in a frame 2 of a product accommodating device 1, and the motor 3 is a cylindrical pot-like shape that is horizontally rotatably installed on the frame 2. The container 4 is intermittently rotated. An arm 2a is erected on one side of the frame 2, and a front end of a chute 5 described below is supported on the upper end of the arm 2a so as to be rotatable about a horizontal axis via a support shaft 2b. Has been done.

As shown in FIGS. 1 to 3, the chute 5 is formed by forming an aluminum plate into a gutter shape having a substantially U-shaped cross section, and has a gate-shaped mounting frame at the center and the rear end thereof. 5a and 5b are attached, and plate-shaped first and second gates 6a and 6b are provided which can slide along the mounting frames 5a and 5b to open and close the chute. First and second air cylinders 7a and 7b are fixed to the upper portions of the mounting frames 5a and 5b, and rods 7c and 7d of both air cylinders 7a and 7b are connected to the upper ends of the first and second gates 6a and 6b. Has been done. A photoelectric sensor 8 is attached to the chute 5 at a position slightly forward in the longitudinal direction from the central portion, so that the product passing through the chute 5 can be detected.

A sliding plate 5c made of resin is attached to the rear end portion of the chute 5 so that the chute 5 can smoothly slide on the container 4. The inner surface of the chute 5 and the front surfaces of the first and second gates 6a and 6b are coated with urethane resin 9 as a cushioning material.

The control device 10 provided on the frame 2 includes a drive control circuit for intermittently rotating the motor 3, a detection unit of the photoelectric sensor 8, and a predetermined unit for the first and second air cylinders 7a, 7b. It contains an electromagnetic valve for supplying air at the timing and a sequence control circuit for controlling these, and the electromagnetic valve is connected to an air supply source such as a compressor (not shown) via the hose 10a. ing. Then, the control device 10 operates the first and second air cylinders 7a and 7b after the photoelectric sensor 8 detects the product, and sets the first and second gates 6a and 6b to the preset timing. It opens and closes in sequence. The control device 10 and the first and second air cylinders 7a and 7b constitute a control mechanism in the present invention.

Next, the operation of the product storage device 1 configured as described above will be described. As shown in FIG. 1, in the product accommodating device 1, the front end of the chute 5 is located at the chute 5 with respect to the inner bottom surface (product mounting surface) of the container 4 with respect to the conveyor C serving as the product discharge part of the automatic machine. The rear ends of the two are installed so that they are located close to each other. The products transferred by the conveyor C at predetermined time intervals sequentially drop from the end of the conveyor and slide down in the chute 5. At this time, the first gate 6a of the chute 5 is closed, and the product collides with the first gate 6a immediately after being detected by the photoelectric sensor 8 and stops.

When the photoelectric sensor 8 detects the product, the control device 10 switches the solenoid valve to send air to the first air cylinder 7a and open the first gate 6a. At this time, the second gate 6a is closed, and the product that starts sliding in the chute 5 from the position of the first gate 6a collides with the second gate 6b and stops. After that, the control device 10 switches the solenoid valve at a predetermined timing to send air to the second air cylinder 7b and open the second gate 6b. That is, the product that slides down in the chute 5 collides with the first gate 6a and the second gate 6b in this order, stops temporarily, and then gently slides down into the container 4 from a position close to the product mounting surface.

It should be noted that the control device 10 switches the electromagnetic valves to operate the air cylinders 7a and 7b immediately after the product passes through the gates 6a and 6b to close the gates 6a and 6b, respectively. Have control over. Also, the container 4 is intermittently driven by the motor 3, but the first step is to move one product placed in the container 4 and then slide down to the next product. Is set up to make room for. Therefore, the products accommodated in the container 4 are unlikely to be piled up. Then, after the product almost completely fills the product mounting surface in the container 4, the sliding plate 5c of the chute 5 is brought into contact with the product and lifted, so that the products are stacked in a multi-layered state.

Next, another example of the chute 5 will be described. The chute 11 shown in FIG. 4 has a resin roller 12 rotatably formed at its rear end, and the other structure is the same as that of the chute 5 described above. Therefore, since the chute 11 comes into contact with the inner bottom surface of the container 4 (see FIG. 1) and the product in the container via the roller 12, the chute 11 has a small frictional resistance.

Although the first and second gates 6a and 6b are provided in the chute 5 in the product accommodating apparatus 1 according to the above-described embodiment, the number of gates set is not limited to this embodiment. It can be appropriately set according to the distance from the product discharge part to the container, the product shape, and the like. Further, an electric actuator may be used instead of the first and second air cylinders 7a and 7b.

[0016]

[Effect of device]

 As described above, according to the present invention, the products sequentially discharged from the product discharging unit such as the automatic machine can be stored in the container without damaging them. Therefore, even when processing soft materials, it is possible to operate the automatic machine continuously for a long time and store the product in the same way as when processing general steel materials.During this time, the worker saves time and does other work. It has the effect of being able to stay and rest. Since the product container of the present invention has a relatively simple structure, it is possible to improve the productivity in a factory or the like with a small equipment cost.
