Abstract

PURPOSE:To minimize the deformation of tablets and feed safely without dust adhered thereto by a method wherein disc tablets which have been cut round and piled up vertically are rolled down on an inclined floor to be fed to abase in a preheater, then the base is inclined down to feed the tables to a mold press. CONSTITUTION:When a required number of tablets 2 is indicated to a controller 4, a gate 3 is opened and it is detected by a sensor 5. As the floor surface of a tablet stocker 1 is inclined,the tablets 2 are rolled on an inclined floor surface 1a by dead load and transferred to a preheated 6. The tablets 2 are collided with a wall in the preheater 6. In that case, a base 7 is retained in a horizontal position A, and the tablets 2 are mounted on the base 7 and heated. After that, the base 7 is in an inclined position B, and the tablets 2 are slided down by the dead load and fed to a feed opening 8a of a mold press molding machine 8. Thus, the deformation of the tablets are minimized and fed safely.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for supplying tablets for packaging of a mold press forming machine IC used for processing IC packages.

[Prior Art] Conventionally, a dedicated device for supplying tablets to a mold press forming machine has not been developed, and tablets have been supplied exclusively by hand. That is, a plate-shaped tablet that had been sliced into rounds was taken out from the tablet storage shelf by hand, transferred to a preheater, heated by the preheater, and when the tablet became soft enough to be heated, it was preheated using special metal scissors. The tablet was taken out and fed into the tablet supply port of the mold press machine.

[Problems to be Solved by the Invention] According to the conventional tablet supply method described above, the softened tablet is pinched with metal scissors, so if the tablet is inadvertently pinched too tightly, the tablet may become deformed. It becomes unusable. To avoid this, there is a method of using protective gloves to prevent deformation, but this poses problems such as fine dust adhesion.

Furthermore, since there is a bullet supply port on the top of the mold press machine, it is dangerous to work with, and you must be careful not to touch the surrounding operation switches or get burned when supplying the bullet. There is a problem that cannot be solved.

Incidentally, since tablets used in IC packages can be sufficiently produced in small quantities, there is no need for unnecessarily large tablets. Therefore, there has been a desire for a small preheater for ICs that does not require equipment to heat and insert a large number of tablets.

An object of the present invention is to provide a tablet feeding device that solves the above problems.

[Differences between the Invention and the Prior Art] In contrast to the conventional tablet feeding described above, the present invention has an original content in that the tablet is fed by rolling the tablet and utilizing its own weight.

[Means for Solving the Problems] The present invention provides a supply device for supplying tablets to a tablet supply port of a mold press forming machine, and includes a tablet stocker for vertically stacking and storing sliced disk-shaped tablets; and a preheater for preheating the tablets discharged from the tablet stocker, the floor surface on which the tablets of the tablet i-stocker are rolled is inclined toward the discharge port, and the tablets are rolled and supplied along the inclined floor surface. The tablet supply device is characterized in that a base for holding the tablets in the preheater is installed so as to be tiltable downward toward the tablet supply port of the mold press forming machine.

[Example] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, the present invention includes a tablet stocker 1 that vertically stacks and stores sliced disc-shaped tablets 2, and a preheater 6 that preheats the tablets 2. It is arranged between the hook 1 and the mold press forming machine 8.

The floor surface 1a on which the tablets 2 of the tablet stocker 1 are rolled is tilted downward toward the discharge port 1b, and a gate 3 is provided at the discharge port 1b of the tablet stocker 1, and a sensor 5 for detecting the tablets 2 is provided behind the gate 3. and a controller 4 that controls opening and closing of the gate 3 based on the detection output of the sensor 5. Further, the preheater 6 is provided with a supply port 6a that communicates with the discharge port 1b of the tablet stocker 1, and a base 7 that holds the tablets 2 rolled and supplied along the inclined floor surface 1a in the preheater 6. is pivotally supported around a horizontal shaft 7a so as to be tiltable downward toward a tablet supply port 8a of a mold press forming machine 8.

In the embodiment, the supply of the tablets 2 entering the tablet stocker 1 is controlled by a gate 3. When the required number of tablets is instructed to the controller 4, the gate 3 is opened and detected by the sensor 5, and the required number of tablets is supplied to the preheater 6.

Since the floor surface of the tablet stocker 1 is inclined, the tablets 2 roll on the inclined floor surface 1a due to their own weight and are sent to the preheater 6. The tablet 2 that has rolled up to the preheater 6 collides with the wall inside the preheater 6 and is stored on the base 7. In this case, since the base 7 is held in the horizontal position Δ, the tablet 2 is mounted on the base 7 and heated using microwaves. When the tablet 2 is heated in the preheater 6 for a certain period of time, the base 7 in the preheater 6 changes its posture to the tilted posture B and tilts, so that the tablet 2 on the base 7 becomes the tilted base γ due to the mountain hand.
It slides down from above and is supplied to the supply port 8a of the mold press forming Ia8.

According to the present invention, the number of heaters supplied can be adjusted by controlling the opening and closing of the gate 3, and a small preheater can be used.

[Effects of the Invention] As explained above, according to the present invention, tablets can be automatically supplied to a mold press forming machine by utilizing the rolling, dead weight, and falling of the tablet.

By automatically supplying tablets as IC packaging material, the deformation of the tablets is minimized, the tablets can be supplied safely without the use of human hands, and the tablets can be disposed of without causing excess dust to adhere to them. effective.
