The invention provides an oven.

Referring to fig. 1, in one embodiment of the present invention, the oven includes:

an oven inner chamber 10 provided with a feeding position 11 and a discharging position 12;

a heating device 20 for providing heat to the oven chamber 10; and

transmission device 30, including transmission carrier 31, and with transmission carrier 31 drive connection's drive assembly, transmission carrier 31 at least certainly the material level 11 extends to go out material level 12, drive assembly is used for every preset time quantum drive transmission carrier 31 transmission preset distance.

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.

In this embodiment, further, the heating device 20 includes a heating air duct 21 having at least one end communicating with the oven inner chamber 10, and a fan 22 and a heater 23 disposed in the heating air duct 21, where the heater 23 is located at a front side of the fan 22. In this embodiment, the air in the oven inner chamber 10 is heated by supplying hot air to the oven inner chamber 10, and the hot air can be diffused to each corner of the oven inner chamber 10, which is beneficial to improving the uniformity of the temperature in the oven inner chamber 10. However, the design is not limited thereto, and in other embodiments, the air in the oven inner chamber 10 may be heated by providing a heating wire or the like in the oven inner chamber 10.

Optionally, both ends of the heating air duct 21 are communicated with the oven inner chamber 10, so that a circulating hot air supply mode can be realized, heat of air flow can be recycled, heat loss is reduced, heating cost of the oven is reduced, and heating efficiency of the oven is improved.

In this embodiment, the oven further includes a temperature monitoring device and an MES trace System (Manufacturing Execution System) electrically connected to the temperature monitoring device, where the temperature monitoring device is configured to monitor temperature data of the oven internal chamber 10 and send the temperature data to the MES trace System for storage; therefore, historical curing and baking temperature data on a production line can be traced conveniently, and relevant reference and evidence are provided for troubleshooting of product abnormal reasons. Generally, the temperature monitoring device may employ, but is not limited to, an ohmic thermostats E5CC to collect the temperature data.

It should be noted that, in this embodiment, optionally, the temperature data obtained by monitoring by the temperature monitoring device may also provide feedback for the heating device 20, so that when the temperature in the oven internal chamber 10 swings due to a door opening action or the like, the temperature in the oven internal chamber 10 is quickly brought to the preset temperature by the heating device 20. In addition, in this embodiment, generally, when the temperature of the oven chamber 10 reaches a preset temperature, the feeding and conveying device 40 conveys the product to be baked onto the transmission carrier 31 on the feeding position 11, and the driving assembly drives the transmission carrier 31 to transmit the product.

In this embodiment, optionally, the oven further includes an alarm device, and the alarm device is electrically connected to the temperature monitoring device and is configured to send an alarm when the monitored temperature is greater than or equal to a preset temperature; that is, the oven that this embodiment provided possesses the temperature alarm mechanism that transfinites to in time remind production line operating personnel to handle the overtemperature situation, avoid waiting to toast the product and influence other performances of product because of the overtemperature toasts, improve the work security of oven.
