[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for stopping punching operation in a machine for punching food dough or other objects by vertically moving the punch such as a mochi punching machine and a punching machine. Is.

[0002]

[Prior art]

 It is known that punching machines such as rice cake punching machines lift the punches and punch them by free-falling motion of the punches, and punching machines by reciprocating punches using a crank mechanism. There is. Needless to say, when the punching operation of these machines is stopped, the punches must of course be stopped at the position where the punches were raised. Since it is controlled, it is sufficient to simply stop the drive device at a predetermined position, and the fine adjustment operation can be easily performed even if the stop timing deviates slightly.

On the other hand, in a machine that performs punching in a free-fall motion of the punch, the punch must be stopped before the punch is dropped, and if the stop timing deviates, the punch is dropped and installed. Stops and you cannot take out the dough.

A conventional stop mechanism of the former machine is configured to receive a cam body (a driving source of the punch body) when the punching portion (the whole body that moves up and down) is lifted for punching. Means for acting a fall-preventing member of the punching part on the part, and a stopper body 03 is fitted into the recess 02 provided in the punch rod 01 as shown in FIG. 7 to prevent the punching part from falling. There is.

[0005]

[Problems to be solved by the device]

 Among the stopping mechanisms of the conventional machine described above, the means for interposing the blocking member in the cam receiving portion is provided with a stopping mechanism corresponding to the case where the cam receiving portion itself is located at a high place of the machine and is also located at the highest position. It is necessary, and it is an impeding condition when the entire machine is downsized and used, and its manufacture is also complicated.

On the other hand, the fall prevention device by fitting the recessed portion 02 of the punch rod 01 and the stopper body 03 illustrated in FIG. 7 has a simple structure and is easy to manufacture. Had to manually operate the operation lever 04 of the stopper body 03.

For this reason, the operation timing depends only on the judgment of the operator, and if the operation timing deviates, it may not be possible to stop the pestle in the raised position, leading to a reduction in the efficiency of the pestle work itself. It was Therefore, the present invention proposes a device for mechanically operating the human-powered operation.

[0008]

[Means for Solving the Problems]

 The operation stopping device of a rice cake punching machine according to the present invention comprises a punching body having a punching body provided at the lower end of the punching rod and a cam receiving portion at the upper portion, a cam body for lifting the punching portion upward, and this cam. In a mochi machine that punches by free-falling motion of a punch composed of an operating part consisting of a drive source for the body, the groove formed in the middle of the punch and the passage hole of the punch are A board part that is bored and is provided laterally in the groove position at the uppermost position of the punch, a stopper body that is slidably fitted in the groove and that is provided on the base plate, and a sensor that detects the operation of the punch are provided. It is characterized by comprising a slide drive part of a stopper body which is attached and whose operation is controlled by this sensor.

[0009]

[Action]

 The punching operation is performed by rotating the cam body of the operating part to lift the cam receiving part of the punching part upward, and when the cam body is disengaged, the punching part falls and the punching object punches the object to be punched. Is to do. When stopping, the punching part senses a predetermined position (the position where the punched body is lifted) with a sensor, slides the stopper body, and fits the stopper body into the groove. Since it is placed, the free-falling motion of the punching part is prevented.

[0010]

【Example】

 Next, an embodiment of the present invention will be described. The embodiment illustrated in FIGS. 1 to 5 is an example in which the present invention is applied to a punching machine, and the punching machine drives the punching section 1 and the punching section 1 which perform punching operation. It is composed of an operating part 2 and a platform part 3 on which an object to be punched (food material) is placed, and this punching machine is provided with a stop device 4 for stopping the operation of the punching part according to the present invention. .

The punching section 1 is provided with a punching body 12 at a lower end of a punching rod 11, and a cam receiving portion 13 also serving as a weight mounting portion at an upper portion of the punching rod 11. The operating part 2 is provided with a half-moon cam body 21 which can be rotated by a drive source motor. The cam body 21 is rotated to lift the punch rod 11, and the cam body 21 and the cam receiving portion 13 are disengaged from each other. The whole 1 falls freely, and the punching operation by the punch 12 is performed.

The mounting table 3 is composed of a mounting table 31, a base (not shown) arranged below the mounting table 31, and a horizontal moving mechanism for moving the mounting table 31 laterally and circularly. The movement of the punching unit 1 is controlled according to the operation of the punching unit 1, and the dough placed on the placing table 31 is punched uniformly.

The stopping device 4 includes a recessed groove 41 formed in the middle of the punch rod 11, a substrate portion 42, a stopper body 43, a sensor including a microswitch 44, and a slide driving portion of the stopper body 43. In particular, the base plate portion 42 is provided with the through hole 45 of the punch rod 11 and is provided horizontally at the position of the concave groove 41 at the uppermost position of the punch body. The stopper body 43 is a plate-like body and is slidably provided on the base plate portion 42, and a U-shaped gouging portion 46 is formed so as to be slidably fitted in the recessed groove 41.

The micro switch 44 is switched by a switch operating rod 23 attached to the drive shaft 22 of the operating unit 2. The drive unit of the stopper body 43 includes a spring 47 for pulling the stopper body 43 in the fitting direction and an electromagnetic lock 48 for pulling and fixing the stopper body 43 to the non-fitting side. The electromagnetic lock 48 is released by a signal from the micro switch 44.

Then, the punching unit 1 moves up and down by the operation of the operating unit 2 to punch the material on the mounting table 31, and a stop signal input when the user wants to stop or a preset operation time. When the micro switch 44 is turned on after receiving the stop signal issued when the number of times of punching reaches (the number of punches), that is, when the punching portion 1 has a predetermined height, the electromagnetic lock 48 is de-energized, The stopper body 43 is slid by the contracting force of the spring 47, the edge of the gouging portion 46 of the stopper body 43 is fitted into the recess 41 of the punch rod 11, and the punching portion 1 is prevented from free fall, and the punching die is hit. It stops the operation.

The present invention is not limited to the punching machine described above, but can be applied to a rice-cake pouring machine equipped with a die body 5 as shown in FIG. 6 and others, and a stopper body sliding mechanism can be used. The present invention is not limited to the above-mentioned embodiment, and the specific means can be appropriately determined as long as the stopper body performs a predetermined operation.

[0017]

[Effect of device]

 As described above, the present invention is a machine for punching by free-falling motion of a punching section, and a concave groove formed in the middle of the punch and a punching operation by inserting the concave groove. It is composed of a stopper body for stopping the operation and mechanically controls the operation of the stopper body, so that the stopping operation can be surely performed and the punching machine can be safely stopped. .
