SUMMARY OF THE INVENTION However, Japanese Patent Application Laid-Open No. 7-1
The heating device disclosed in Japanese Patent No. 55431 discloses a heating device in which an upstream hot plate and a downstream hot plate are heated by a plurality of hot plates individually rising and descending in an area which individually covers the game board in the transport direction. Although it is easy to control the temperature so that it is different from the temperature, in the heating process in each hot plate, the hot plate moves up and down and the game board moves in the transport direction, so that the hot plate is Easy to cool. Therefore, in order to warm the game board to a predetermined temperature with each hot plate in a short time, the temperature control becomes complicated. The heating device disclosed in Japanese Patent Application Laid-Open No. 7-144545 has a hot plate formed so as to cover three or more game substrates in the transport direction, and increases the heat storage performance by increasing the mass of the hot plate. However, a configuration in which a maximum of two game substrates are located on the upstream side and the downstream side in the transport direction under the hot plate, and a minimum of one game substrate is located only in the intermediate portion under the hot plate Since the game board is warmed three times by alternately repeating the form and the transport mechanism, the heated game board cannot be continuously supplied to the downstream side at a predetermined time interval, and the production efficiency is reduced. I could not deny that.

In view of the above, according to the present invention, a plurality of objects to be heated are heated by a hot plate having a size covering a plurality of objects to be heated such as a plurality of game substrates adjacent to each other in the transport direction, the number of times being equal to the number thereof. An object of the present invention is to provide a heating device for manufacturing a gaming machine that can supply a heating object continuously to a downstream side at predetermined time intervals in order, and can effectively utilize heat stored in a hot plate and improve production efficiency. Things.

[0005]

The object to be heated according to claim 1 is conveyed so as to intermittently repeat movement and stop in one direction, and to a plurality of objects to be heated which are adjacent in the conveying direction while the conveyance is stopped. A heating device for manufacturing amusement machines that presses a hot plate large enough to cover them and heats multiple items to be heated has the same number of heater blocks as the items to be heated adjacent to each other in the transport direction covered by the hot plate, and the hot plate And a transport mechanism for intermittently transporting a plurality of articles to be covered with a feed width corresponding to the interval between the heater blocks. According to this configuration, the transport mechanism intermittently performs the transport operation at the feed width corresponding to the interval between the heater blocks, and the hot plate performs the elevating operation while the transport mechanism is intermittently stopped. Thereby, a plurality of game substrates adjacent to the heater block in the transport direction can be heated a plurality of times and carried out to the downstream side. If the heating elements forming the heater blocks are arranged in parallel in the transport direction at equal intervals, the game boards stopped corresponding to the respective heating elements can be uniformly heated. The front and rear edges in the transport direction of the game board are located between the first heating element and the next heating element on the upstream side in the heater block, and between the last heating element and the heating element immediately before the last heating element. In this case, the peripheral edge of the game board can be uniformly heated as in the intermediate portion. If the temperature of the upstream heater block is controlled so as to be higher than that of the downstream heater block, the game board heated for the first time does not cool down the hot plate, and the game board can be appropriately heated.
