Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a container reversing device that prevents noise generation as much as possible when discharging articles inside the container.

In general, there is an insertion device that uses a container to automatically feed parts such as iron materials (turned and heat-finished products) to the pre-grinding process, and the items are stored in the container or a certain amount is repeatedly fed. Container-inverting equipment is provided in areas where container evacuation is required.

For example, as shown in Fig. 1, the container C itself is turned upside down by an inverting table B that is installed on the frame A and rotates vertically, and the articles are shot from the top of the opening of the container C. It flows out to D and is discharged. However, in this method, the articles in the container C fall directly into the chute D from a high position, so the collision noise between the articles is loud during discharge, and the collision noise between the articles inside the container C is also generated when the container C is turned over. However, there were problems with noise and component quality.

In view of the above-mentioned drawbacks, the present invention aims to install a container inside a frame-shaped reversible box having a lid, and to bring the container into close contact with the lid side using the expansion and contraction force of a cylinder that opens and closes the lid, and to invert the container as one. It is something. In other words, the container inserted into the inverted box -
When the cylinder contracts, the top lid of the inversion box closes and is lifted from the bottom, and the container is held with the open top of the container pressed against the closed top lid.

This is to prevent the collision noise of the items inside the container from leaking outside, which is generated when the container is inverted and rotated in this close state, and to block the noise.Furthermore, when discharging the container, the top lid of the inverted inverted box is gradually opened. This system aims to reduce the number of collisions between objects by discharging the objects in appropriate amounts at a time, thereby lowering the noise level and preventing scratches and the like. DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described in detail below with reference to embodiments shown in the drawings. In FIGS. 2 and 3, 1 is a frame-shaped reversing box without a bottom, 2 is an upper lid rotatably provided above the opening of this reversing box 1, and 3 is a pair of left and right parts for opening and closing the upper lid 2. The piston shaft 4 is connected to the top cover 2 by an air cylinder.

5 are two lift bars penetrated through the sides of the reversing box 1,
While connected to each other by a connecting plate T, they are guided so as to be vertically movable through a vertically long guide hole 6 provided on the side surface of the reversing box 1, and are vertically movable by a cylinder 3 whose base end is connected to the connecting plate T. do.

A roller conveyor 8 is used to easily carry the container 9 into and out of the reversing box 1.

Further, 10 is a rotation axis of the reversing box 1. FIG. 3A shows the state before operation when the container 19 is carried onto the roller conveyor 8 into the reversing box 1.

Next, when the air cylinder 3 is operated and the histone axis 4 is contracted, the upper lid 2 is lowered to the side of the container 9. When the upper lid 2 is completely closed, there is still some margin in the stroke of the piston shaft 4, so the two wrist bars 5 begin to move up the guide hole 6 and lift the container 9 from the bottom of the container 9. The upper part of the opening of this lifted container 9 hits the already closed top lid 2, but there is still some margin in the stroke of the piston shaft 4, and the container 9 is forcibly compressed into the top lid 2 (see Figure 3). reference). When the reversing box 1 is rotated about the rotating shaft 10 while being integrated with the container 9, the sound of collisions between articles in the container 9 will not leak to the outside. Furthermore, when the reversing box 1 is stopped in an upside-down state and the articles are discharged, the upper cover 2 can be opened gradually, preventing the articles from falling all at once, and reducing the height and noise blindness. Next, the structure of the container reversing device using the above reversing box of the present invention will be described in detail as follows. In Fig. 4, 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 are the same as above, 11 is a frame that is the base for configuring the entire device, and 12 is a container 9. A guide roller that carries the reversing box 1 without shifting from side to side, 13 is a geared motor with a brake that rotates the reversing box 1, 14 is a tension sprocket, 15 is an air cylinder for driving the discharge lower cover, and 1 is a friction multi-plate dry type. Clutch, 11 is oil pan, 1
8 is a chute, 19 is a discharge part upper cover, 20 is a discharge part upper cover,
A driving air cylinder, 21 a storage section for storing articles discharged from the container 9, 22 a sensor for detecting the presence or absence of articles in the storage section 21, 23 a worm reducer, 24 a discharge lower cover, and 25 a roller conveyor. It is a stand.

Now, when the container 9 containing the goods is placed on the roller conveyor table 25 by a forklift and pushed by hand, it is guided by the guide rollers 12 provided on both the left and right sides and the roller conveyor 8 below, and is easily and lightly placed in the reversing box 1. to go into.

At this time, the top lid 2 of the reversing box 1 is in an open state. Next, when a cycle start push button switch (not shown) is pressed, the top cover 2 is closed by the operation of the air cylinder 3 in about 7 seconds. Further, the container 9 is lifted and pressed against the upper lid 2 by the lift bar 5 using the excess stroke of the air cylinder 3. After that, about 4 seconds (switch 0N)
11 seconds later), the motor 13 starts rotating, moves the worm reducer 23 by chain drive, and the coaxially coupled reversing box 1 starts rotating upward about the rotating shaft 10. The drive system is provided with a tension sprocket 14 for improving the tension of the chain, and a friction multi-plate dry clutch 16 for transmitting driving force 0N-0FF. Furthermore, when the inverter box rotates approximately 125 degrees, a limit switch (not shown) is actuated thereby causing motor 13 to rotate.
stops.

Next, the upper cover 2 begins to open due to the action of the air cylinder 3. It takes about 30 seconds to fully open. During this time, the articles in the container 9 are gradually discharged and put into the storage section 21 for storage. It is waiting in that state. When a signal to discharge is received from a rotary hopper or a conveyor installed at the rear stage of the apparatus of the present invention, the discharge section upper cover 19 and discharge section lower cover 24 are moved to the rear by the air cylinders 20 and 15 for vertically driving the discharge section. The article is opened upward, the lower lid 24 is rotated upward to the position shown by the dashed line, and the article is discharged into the discharge chute 18. At this time, the lower lid 24 prevents all the articles from being discharged at once. As a result, when the discharge operation occurs 4 to 5 times, the storage storage section 21 becomes empty, and a warning light (not shown) is activated to provide supplementary light to notify the operator that the light is decreasing. . After checking the light, the worker switches the machine operation to manual and operates the reversing switch of the motor 13 to return the reversing box 1 to the bottom. Thereafter, the empty container 9 is replaced with a new container 9 filled with articles, and the above-described operations are repeated. As explained above, the present invention provides a frame-shaped reversible box that has an opening for receiving a container on one side and is reversible about the upper turning axis, and is provided with an openable and closable upper lid. At the same time, a lift bar is installed horizontally on the bottom of the reversing box and is capable of raising and lowering the container, and air cylinders for opening and closing the upper lid are connected to the upper lid at one end and are erected on both sides of the reversing box. Since the other end is connected to both ends of the lift bar 1, and the air cylinder is used for raising and lowering the lift bar 1, it is possible to raise the lift bar 1 and bring the upper opening of the container 1 into complete contact with the upper lid, and the reversal is possible. At times, it is possible to confine the noise of collisions between articles in the container and prevent it from leaking outside, thereby suppressing the generation of noise as much as possible. Also, since the air cylinder for opening and closing the top cover is also used for raising and lowering the lift bar,
The configuration of the device becomes simple. Furthermore, when parts are loaded into the storage section from the container, the top cover is opened gradually so that the objects do not flow into the storage section all at once, thereby reducing the difference in falling of the objects, thereby reducing noise. In the case of the conventional method, 105 dB of noise was generated, but with the device of the present invention, the noise was 90 dB.
The result is B, and the effect of noise reduction can be recognized by light. Therefore, the problem of noise due to the outside of the partition in the current container turning device is solved by the present invention.
