DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for transporting a positive electrode mixture formed in a ring shape by a molding machine to a next step at high speed and in a stable manner, and removing molding burrs of the positive electrode mixture and forming a defective positive electrode. TECHNICAL FIELD The present invention relates to a mixture transporter capable of reliably and automatically discharging a mixture.

[0002]

2. Description of the Related Art In general, as shown in FIG. 6, a positive electrode mixture 4 for a cylindrical alkaline battery or the like is produced by pressing a powdery positive electrode active material into a ring shape on a rotary type molding machine 1. Then, the positive electrode mixture 4 after the pressure molding is forcibly changed direction by a damper 16 provided near the outlet of the molding machine 1, passed from the molding machine 1 to the conveyor 12 and sent to the next step.

That is, the positive electrode mixture 4 whose moving direction has been changed by the damper 16 (switching from rotational movement to linear movement) passes over the transfer plate 15 by inertia due to the rotation of the molding machine 1 and is installed immediately thereafter. It is delivered to the transport conveyor 12 and transported. Then, the molding burrs generated during the mixture molding are removed by the dust collection port 14 attached above the conveyor 12.

[0004]

However, in such a conventional system, when the positive electrode mixture delivered from the molding machine passes over the transfer plate, it falls over due to a step with the molding machine or mechanical vibration. Because the positive electrode mixture placed on the conveyor is moved only by its own weight and the friction of the conveyor belt, it is extremely unstable, such as overturning due to mechanical vibration during transportation. This is a factor that lowers the operating rate of the machine.

[0005] Further, since the above-mentioned method of removing molding burrs is a non-contact method utilizing wind pressure, it is difficult to completely remove burrs, and the burrs are often carried to the next step with the burrs remaining. This is also a factor that lowers the operation rate.

[0006] On the other hand, in the mixture molding process, the quality of the positive electrode mixture is checked based on the molding pressure value. Even if a defective product can be detected accurately, a highly reliable discharge capable of reliably discharging the defective product can be performed. There was a disadvantage that there was no mechanism.

An object of the present invention is to solve the above-mentioned drawbacks, to convey a positive electrode mixture delivered from a molding machine at high speed and in a stable manner, and to reliably remove molding burrs and discharge defective products in a conveying process. An object of the present invention is to provide a mixture transporter having a function.

[0008]

The positive electrode mixture (4) formed into a ring shape by a continuous rotary molding machine (1) having a rotatable turntable (2) is formed by the molding machine (1). ) In the mixture transporter which takes out the product, transfers it to the transport conveyor (12), and transports it to the next process, the molding machine (1) detects a defect of the positive electrode mixture (4) after molding. (5) and a sensor (6) for detecting the passage of the positive electrode mixture (4). The turntable (2) is provided between the molding machine (1) and the conveyor (12). A work guide (8) for changing the direction of the positive electrode mixture (4) above and a profile (7a) at an interval where the direction-changed positive electrode mixture (4) can be separated and clamped one by one.

A transfer device (18) composed of support plates (13, 17) for supporting the lower surface from below, and a roll-shaped deburring brush (9a) on the timing belt conveyor (7);
A deburring device (9) for the positive electrode mixture (4) comprising a motor (9b) for rotating this and a collecting mechanism (9c) for the removed burr powder is additionally provided. A defective product elimination device (10) for discharging defective products based on a discharge signal (S) from a defect detection device (5) of the molding machine (1) and a detection pulse (P) from a sensor (6).
And was configured.

[0009]

[Work] With the above configuration, the positive electrode mixture after molding is turned by a work guide provided near the exit of the molding machine, and is conveyed while being sandwiched by a timing belt conveyor having a profile. Since the positive electrode mixture is separated and pinched one by one by the profile of the conveyor, it does not fall over due to a step or mechanical vibration during transportation. When passing through the deburring device during transportation, the upper surface of the positive electrode mixture comes into contact with the deburring brush, and the molded burrs are completely removed.

Further, the quality of the positive electrode mixture after molding is checked by a defect detecting device, and a defective product is discharged by operating a defective product excluding device in accordance with a discharge signal. Transported to

FIG. 1 shows the structure of a mixture transporter according to the present invention.

In FIG. 1, reference numeral 1 denotes a continuous rotary system for forming a positive electrode mixture. Reference numeral 2 denotes a turntable which rotates at a constant speed in the direction of arrow A. A plurality of (ten in FIG. 1) molds (mouse) 3 are disposed on the turntable 2, and the positive electrode active material is loaded into the mold 3 while the turntable 2 makes one rotation. Then, a series of steps such as pressurizing the loaded positive electrode active material sequentially proceed, and in the final step, the positive electrode mixture 4 temporarily formed into a ring shape is produced one after another at regular intervals.

The molding machine 1 has a defect detecting device 5 for detecting abnormalities in height and weight of the positive electrode mixture 4 based on the molding pressure value and checking the quality, and for controlling the position of the defective product. A sensor 6 for detecting passage of the positive electrode mixture 4 is provided. Incidentally, an optical sensor or a proximity switch is used for the sensor 6.

In the vicinity of the outlet of the molding machine 1, the positive electrode mixture 4 is discharged outside the machine, and a work guide 8 for guiding the simultaneously transported positive electrode mixture 4 from the side, a support plate 13 for guiding from the lower side, and The timing belt conveyor 7 is installed along the fixed line 17, and constitutes a transport device 18. The timing belt conveyor 7 has a plurality of profiles 7 at intervals capable of holding the positive electrode mixture 4.
a are installed at equal intervals. The support plate 17
Is fixed to the upper part of the powder receptacle 9c1 to be described later.
A number of small holes 17a are formed as shown in FIG.

The timing belt conveyor 7 is driven by a power source common to the molding machine 1 and rotates in the direction of arrow D.

A deburring device 9 is provided on the timing belt conveyor 7. The deburring device 9 is a device for removing burrs generated when the positive electrode mixture 4 is formed. As shown, a roll-shaped deburring brush 9a
(Preferably made of horsehair), a motor 9b for rotating it in the direction of arrow B, and a burr powder collecting mechanism 9c. The collecting mechanism 9c includes a powder receiver 9c1, a hose 9c2, a powder collecting container 9c3, and the like. A defective product elimination device 10 using a rotary actuator 10a is installed at the end of the timing belt conveyor 7. In addition, a discharge chute 11 for discharging defective products out of the apparatus is attached thereto. This defective product elimination device 1
The transport conveyor 12 that rotates in the direction of arrow C is connected to the transport conveyor 12 via the “0”.

The configuration of the mixture transporter according to the present invention has been described above. With this configuration, the positive electrode mixture 4 delivered from the molding machine 1 can be transported at high speed and in a stable manner, and the positive molding can be reliably performed in the transport process. The burrs are removed and defective products are discharged, and can be transferred to the next process via the conveyor 12.

That is, the positive electrode mixture 4 turned around at the tip of the work guide 8 installed near the exit of the molding machine 1
Are separated one by one by the profile 7a and are forcibly discharged out of the molding machine 1. In this case, as described above, since the power source of the timing belt conveyor 7 and the power source of the molding machine 1 are shared, the rotation speed of the molding machine 1 and the transport speed of the timing belt conveyor 7 operate in any case in synchronization. Therefore, the positive electrode mixture 4 can be smoothly transferred to the timing belt conveyor 7 without causing a timing shift.

As described above, the positive electrode mixture 4 on the timing belt conveyor 7 is separated one by one and firmly held by the profile 7a, so that even if there is a slight level difference or mechanical vibration, The positive electrode mixture 4 is stably conveyed without falling, and passes through a deburring device 9 to remove molding burrs generated in the molding process. The deburring device 9 scrapes burrs by bringing the tip of a rotating deburring brush 9a into contact with the upper surface of the positive electrode mixture 4 being conveyed.
The recovery mechanism 9c falls down from a small hole 17a formed in
Is stored in the container 9C3.

Also in this case, the positive electrode mixture 4 has the profile 7a
Therefore, even if the brush 9a contacts the rotating deburring brush 9a, there is no trouble that the positive electrode mixture 4 falls down due to the impact.

Further, the positive electrode mixture 4 after the deburring is carried to the defective product removing device 10 installed at the end of the timing belt conveyor 7, where the non-defective / defective products are sorted.

That is, as described above, in the molding machine 1, during the molding process, the quality of the positive electrode mixture 4 is checked by the defect detection device 5, and if there is an abnormality in the height or weight of the positive electrode mixture 4, it is discharged. The signal S is sent to the defective product elimination device 10.
Upon receiving this, the defective product elimination device 10 counts the detection pulses P sent from the sensor 6 at the same time, operates the rotary actuator 10a at an appropriate timing when the defective product arrives, and reliably discharges only the defective product. Discharge to 11 In this way, the defective product can be accurately discharged because the positive electrode mixture 4 is conveyed one by one by the profile 7a and the position of the defective product is accurately managed by counting the detection pulses P. This is because the positive electrode mixture 4 discharged in this way is accommodated in the container 9C via the discharge chute 11. In the case of a good product, the rotary actuator 10a does not operate, and the positive electrode mixture 4
Handed over to 2. The above is a series of operations, and the block configuration is shown in FIG.

The molding machine 1 described in the present embodiment is a single molding system in which the molding process of the positive electrode mixture 4 is completed by one rotation of the tongue table 2, but the present invention is not limited to this. For example, a double molding system (0 to 180 °, one molding process) capable of performing two molding processes with one rotation of the tongue table 2
Process (180 ° to 360 °, one process). As shown in FIG. 4, the transport system in this case requires two sets of the timing belt conveyor 7, the deburring device 9, or the defective product removing device 10, the transport conveyor 12, and the like. The productivity can be greatly improved because it can be doubled.

[0024]

As described above, according to the present invention, a positive pressure mixture formed on a turntable of a molding machine is transported by a work guide, a support plate, and a timing belt conveyor having a profile. , So that the positive electrode mixture after molding discharged outside the molding machine is separated and pinched one by one by the profile of the timing belt conveyor. Troubles such as the positive electrode mixture falling over due to steps or mechanical vibration of the conveyor are eliminated, and stable transport operation can be performed, so that the operation rate can be greatly improved and high-speed processing can be performed.

Further, the deburring device attached to the timing belt conveyor employs a method in which the rotating deburring brush is brought into contact with the positive electrode mixture and scraped off, so that the molded burrs can be reliably removed.

Further, since a defective product elimination device which operates by a discharge signal and a detection pulse sent from the molding machine is provided at the end of the timing belt conveyor, only the defective positive electrode mixture can be reliably removed. .
