Description

Detailed Description of the Invention: Industrial Field of Application In a tablet conveying device of an IC molding device, a plurality of tablets are received from a preheater in a plurality of pots, and these pots are inserted into the tablet input slot (hereinafter referred to as metal) of the next mold. The present invention relates to a tablet conveying device in which the distance between each pot can be changed during, before, or after the tablet is moved to a mold input port.

Conventional technology Conventionally, this type of tablet conveying device has a plurality of pots arranged in accordance with the plurality of tablet discharge ports of a preheater, and these pots receive a plurality of tablets and the distance between the pots is adjusted from the preheater to the mold input port. A plurality of tablets I-' are moved by a moving device without being changed, and a plurality of tablets I-' are fed into the mold inlet at the same time.

Note that the pot spacing is fixed and cannot be changed, and the distance between the pots is also the same as the distance between the mold inlets. That is, the distance between the tablet discharge ports of the break heater and the distance between the mold input ports are the same.

Problems to be Solved by the Invention Since the distance between the pots of the tablet conveying device is fixed and cannot be changed, the pots that have received the tablet are moved as they are to the mold input port, and all the tablets are loaded into the mold input port. Therefore, the distance between the mold input ports and the distance between the tablet discharge ports of the preheater are made to be the same.

Therefore, the larger the mold, that is, the greater the number of molded products, the larger the distance between the mold inlets, and the distance between the preheater's tablet outlet must be increased to match this distance. . However, when the pre-heater uses high-frequency heating, the distance between the electrodes of the high-frequency heating device and the distance between the tablet ejection ports are usually made to be the same, which simplifies the pre-heater device. Therefore, as the mold becomes larger and the distance between the mold input ports increases, the distance between the preheater discharge ports also increases. This also increases the distance between the electrodes, making it impossible to use one set of high-frequency oscillators, requiring multiple sets, and increasing the size of the high-frequency oscillator.
This was not desirable as it increased production costs.

The present invention has been made in order to solve the above-mentioned drawbacks. The purpose is to be able to change the preheater according to the distance between the openings, and to be able to freely design the preheater without being restricted by the distance between the mold inlet openings, and to create a small, lightweight, and low-cost preheater. This is a tufflet conveying device.

Means for Solving the Problems The tablet conveying device of the present invention includes a plurality of pots for receiving tablets, a plurality of blocks to which these pots are attached, a guide shaft that serves as a guide when these blocks move, and a guide shaft for guiding the blocks. A moving mechanism that moves simultaneously;
a changing mechanism that changes the distance between the blocks, the distance between the blocks is changed while a plurality of blocks are moved simultaneously by the moving mechanism, or the distance between the blocks is changed before or after the movement, and the distance between the pots is changed by changing the distance between the blocks. This makes it possible to match the distance between the mold input ports.
