In this embodiment, the preset time period is generally set according to the product line beat, and is generally set as the time length of the product line beat.
It can be understood that, in the present embodiment, since the feeding position 11 and the discharging position 12 are fixed, the total distance between the feeding position 11 and the discharging position 12 in the direction of the transmission carrier 31 is fixed; in addition, the driving component drives the transmission carrier 31 based on the interval of the preset time period, that is, whether the transmission carrier 31 is fully loaded with the product to be baked or not, the driving component drives the transmission carrier 31 to transmit based on the interval of the preset time period, so that the curing time of any product to be baked, which is transmitted from the feeding position 11 to the discharging position 12, in the oven inner chamber 10 is fixed to the total distance/the preset distance of the preset time period, that is, the curing time of any product to be baked, which enters the oven inner chamber 10, is fixed, thereby improving the accuracy of the curing time of the baking and curing of the product.
It should be noted that, in this embodiment, the oven may have a plurality of modes, including a normal mode, in which the driving assembly drives the transmission carrier 31 to transmit a preset distance every preset time period, so as to ensure that the curing time of any product to be baked entering the oven inner chamber 10 is fixed; optionally, the plurality of modes may further include a fast-back mode in which the driving assembly continuously drives the transmission carrier 31 to transmit, so as to enable fast back-out of all baked products in the oven chamber 10, if necessary.
In this embodiment, further, the oven further includes a feeding and carrying device 40, and the feeding and carrying device 40 is used for carrying the product to be baked onto the transmission carrier 31 located at the feeding position 11.
It can be understood that the addition of the feeding and carrying device 40 can automatically carry the product to be baked to the oven inner chamber 10, which is beneficial to improving the automation degree of the oven, reducing the labor cost and improving the production efficiency. However, the design is not limited thereto, and in other embodiments, the feeding and carrying device 40 may not be additionally arranged, and the operator in the production line may directly and manually carry the product to be baked to the transmission carrier 31 of the feeding position 11.
Optionally, the oven further comprises an outfeed handling device 50, and the outfeed handling device 50 is configured to handle the baked product away from the transmission carrier 31 at the outfeed location 12.
It can be understood that the addition of the discharging and carrying device 50 can automatically carry the baked product away from the oven inner chamber 10, which is beneficial to improving the automation degree of the oven, reducing the labor cost and improving the production efficiency. However, the design is not limited thereto, and in other embodiments, the baked product may be directly and manually moved away from the transmission carrier 31 of the discharge position 12 by an operator on the production line without adding the discharge conveying device 50.
It should be noted that the input material handling device 40 and the output material handling device 50 can be realized by, but not limited to, a robot device or a movable suction device.
In this embodiment, the transmission carrier 31 needs a first time period for transmitting the preset distance, and the first time period is less than the preset time period. Taking the product line beat as 4 seconds for example, usually, the preset time period is set to 4 seconds, and the first time period required by the driving assembly to drive the transmission carrier 31 to transmit the preset distance is usually set to less than 4 seconds, such as but not limited to two seconds, three seconds, etc. Further, during each preset time period, when the driving assembly drives the transmission carrier 31 to transmit, the incoming material handling device 40 and the outgoing material handling device 50 are both in a stop state; when the driving assembly stops driving the transmission carrier 31, the input carrying device 40 and the output carrying device 50 can be in a working state.
In this embodiment, since the first time period is less than the preset time period, that is, in each preset time period, the time taken for the driving component to drive the transmission carrier 31 to transmit only occupies a part of the preset time period, so that the handling action of the infeed handling device 40 and the outfeed handling device 50 and the driving action of the driving carrier 31 can be operated independently of each other during each of the preset time periods, thereby realizing that the feeding and carrying device 40 and the discharging and carrying device 50 do not carry out carrying actions when the transmission carrier 31 is transmitted, and, when the feeding and carrying device 40 and the discharging and carrying device 50 perform carrying actions, the transmission carrier 31 does not transmit, that is, the interlocking control between the carrying device and the transmission device 30 can be realized, and the operation stability of the oven is improved.
In this embodiment, optionally, the transmission carrier 31 is configured as a transmission chain. It can be understood that the transmission chain has the characteristic that each chain link is equal in length, which is beneficial to accurately controlling the transmission distance of the transmission carrier 31, and is further beneficial to improving the precision of the curing time. However, the design is not limited thereto, and in other embodiments, the transmission carrier 31 may also be configured as, but not limited to, a conveyor belt.
Furthermore, the drive assembly comprises a servo motor in driving connection with the transmission chain and a PLC controller electrically connected with the servo motor, and the PLC controller controls the servo motor through output pulses. It will be appreciated that the servo motor can precisely control the rotational stroke of its output shaft, and thus can effectively and precisely control the transmission distance of the transmission carrier 31. In addition, the output pulse of the PLC controller is used for controlling the servo motor, so that the transmission chain can be conveniently driven once by the servo motor every other preset time period; however, the present disclosure is not limited thereto, and in other embodiments, other controllers may be adopted to precisely control the driving time interval of the servo motor, for example, but not limited thereto, a control chip with corresponding functions is adopted to control.
Optionally, the driving assembly further comprises a switching value triggering device electrically connected with the PLC controller to control an output pulse of the PLC controller through a switching value input signal. In this embodiment, the switching value triggering device is configured to monitor a rotation stroke of an output shaft of the servo motor, and convert the rotation stroke into a switching value signal (READY signal) to control an output pulse of the PLC controller, so as to avoid an idling phenomenon of the servo motor; specifically, after the interval of the preset time period, the PLC controller needs to receive the READY signal to send a next pulse signal. Optionally, the switching value triggering device includes a cam linked with the output shaft of the servo motor and a tact switch provided corresponding to the cam, and when the output shaft of the servo motor rotates by a preset rotation stroke, the cam can rotate by one turn, so that the tact switch is triggered once to generate the switching value signal.
