[0037] As labor costs, plant costs and raw material costs continue to rise, the production burden of enterprises has been seriously increased, and the market competitiveness of enterprises has been correspondingly reduced. In order to improve the market competitiveness of enterprises and reduce labor costs, more and more enterprises are moving towards automation, hoping to replace part of the labor with machinery, thereby reducing the need for manual production and thus reducing labor costs.

[0038] In the food baking industry, in order to solve the problem of high temperature of utensils causing burns to personnel and improving the food safety factor, the embodiment of the utility model provides an automatic stacking device, which can automatically stack the utensils during the turnover of the production line, reduce manual operations, and improve food hygiene safety and production efficiency in the baking process.

[0039] The technical solution of the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0040] Figure 1 It is a structural schematic diagram of an automatic stacking device shown in an embodiment of the utility model;

[0041] Figure 2 It is a top view of the automatic stacking device shown in an embodiment of the utility model.

[0042] See also Figure 1 to Figure 2 , an automatic stacking device provided by an embodiment of the utility model comprises a frame 1 having a stacking cavity arranged along its own height direction, and the frame 1 is provided with a horizontal conveying mechanism 2 and a vertical lifting mechanism 3;

[0043] A clamping mechanism 4, the clamping mechanism 4 comprises clamping members 41 arranged on both sides of the stacking cavity and a power assembly 42 driving the clamping members 41 to reciprocate along the width direction of the frame 1, the power assembly 42 being arranged on the vertical lifting mechanism 3;

[0044] The limiting mechanism 5 includes a vertical rod assembly 51 arranged on both sides of the stacking cavity and a driving assembly 52 driving the vertical rod assembly 51 to reciprocate along the width direction of the frame 1, and the driving assembly 52 is arranged on the frame 1.

[0045] The embodiment of the present application takes a baking tray used for baking as an example to explain the embodiment of the present application in detail.

[0046] In the embodiment of the present application, the automatic stacking device includes a frame 1, a clamping mechanism 4 and a limiting mechanism 5; wherein, a horizontal conveying mechanism 2 and a vertical lifting mechanism 3 are provided on the frame 1. The working process of the device is as follows: the horizontal conveying mechanism 2 conveys the baking tray of a process on the production line to the working range of the stacking chamber, the control system on the device controls the power component 42 to drive the clamping member 41 to move along the width direction of the frame 1 (i.e., the width direction of the stacking chamber), the clamping member 41 clamps the baking tray, the control system controls the vertical lifting mechanism 3 to move upward along the height direction of the frame 1 (i.e., along the height direction of the stacking chamber), and drives the clamping mechanism 4 to move upward, lift the baking tray, and maintain the clamping device for the frame apparatus. Before the next baking tray reaches the stacking cavity, the clamping member 41 always clamps the baking tray. When the next baking tray reaches the stacking cavity, the clamping mechanism 4 moves downward under the drive of the vertical lifting mechanism 3. Under the drive of the power assembly 42, the clamping member 41 releases the baking tray that has been stacked, and stacks the baking tray that has been stacked on the current baking tray. Then, the clamping member 41 is driven by power to clamp the baking tray that has been stacked, and the baking tray that has been stacked is lifted by the vertical lifting mechanism 3. In addition, during the stacking operation, the stacked baking trays are limited by the limiting mechanism 5 to prevent the baking trays from being stacked too high and causing the center of gravity to be unstable and thus overturning.

[0047] The limiting mechanism 5 provided in the automatic stacking device can fix the baking tray during the stacking operation. When the number of stacked baking trays reaches the limit that the device can accommodate, the driving assembly 52 can drive the vertical rod assembly 51 away from the stacking cavity, loosening the fixation of the baking tray. At this time, the baking tray can continue to be transported to the next process through the horizontal conveying mechanism 2.

[0048] In one possible implementation, see Figure 2 The horizontal conveying mechanism 2 of the automatic stacking device includes a base 21, a roller 22, a conveyor belt 23 and a first motor 24. The base 21 is provided with a plurality of rollers 22, and the rollers 22 are connected with transmission teeth, which mesh with the conveyor belt 23. The rollers 22 are connected to the first motor 24.

[0049] In a possible implementation scheme, the vertical lifting mechanism 3 of the automatic stacking device includes at least one second motor 31, a transmission belt 32 and a bracket 33, wherein the second motor 31 is fixed on the frame 1, the transmission shaft of the second motor 31 is connected to the transmission belt 32, the transmission belt 32 is connected to the bracket 33, and the bracket 33 is connected to the clamping mechanism 4.

[0050] In one possible implementation, see Figure 3 and Figure 4The vertical lifting mechanism 3 of the automatic stacking device further comprises a slide rail 34 and a slider 35, wherein the slide rail 34 is arranged on the frame 1 along the height direction of the frame 1, and the slider 35 is slidably arranged on the slide rail 34, and the slider 35 is connected to the bracket 33. The slide rail 34 and the slider 35 can improve the overall structural stability of the vertical lifting mechanism 3 and the clamping mechanism 4, and improve the stability and firmness of the clamping mechanism 4 when clamping the baking tray.

[0051] In a possible implementation, the number of the second motors 31 on the automatic stacking device is two. Although a single second motor 31 can realize the lifting and lowering of the clamping mechanism 4, the power provided may be difficult to maintain a stable lifting force. Therefore, by providing two second motors 31, the two second motors 31 jointly increase the power of the baking trays during the stacking process, which can ensure that even if a relatively large stainless steel baking tray is stacked, the stainless steel baking tray can be easily lifted.

[0052] In a preferred embodiment, the second motor 31 can be a stepper motor.

[0053] A stepper motor is an electric motor that converts an electrical pulse signal into a corresponding angular displacement or linear displacement. Each time a pulse signal is input, the rotor rotates an angle or moves forward one step. The angular displacement or linear displacement output is proportional to the number of pulses input, and the speed is proportional to the pulse frequency. Therefore, the stepper motor can accurately control the distance of the up and down movement of the transmission belt 32, and thus can accurately position the travel of baking trays of different sizes.

[0054] In a possible implementation, the power assembly 42 of the automatic stacking device includes a connecting member 421 and a cylinder 422, wherein the first end of the connecting member 421 is connected to the vertical lifting mechanism 3, and the second end is connected to the cylinder 422, and the piston rod of the cylinder 422 is connected to the clamping member 41. During the stacking of the baking trays, the up and down movement of the baking trays is mainly achieved by the lifting of the vertical lifting mechanism 3, and the clamping force provided by the clamping member 41 is only used to ensure that the baking trays do not get loose during the up and down movement. Therefore, the clamping force can be maintained by setting the cylinder 422 or the push rod motor to ensure the smooth operation of the stacking.

[0055] In a possible implementation, the connecting member 421 of the automatic stacking device includes an L-shaped plate 4211 and a reinforcing plate 4212, wherein the first end of the L-shaped plate 4211 is connected to the vertical lifting mechanism 3, the second end of the L-shaped plate 4211 is connected to the cylinder 422, and the reinforcing plate 4212 is respectively connected to both ends of the L-shaped plate 4211. By using the L-shaped plate 4211 and the reinforcing plate 4212, the structural strength of the device in clamping the baking tray can be improved to ensure that the clamping member 41 does not deform.

[0056] In a possible implementation, the guide plate 6 of the automatic stacking device is arranged on the frame 1 and arranged side by side on both sides of the stacking cavity along the conveying direction of the horizontal conveying mechanism 2, and the guide plate 6 is used to level the frame device.

[0057] Specifically, see Figure 1 , and combined with Figure 3 One production line can be used to prepare different foods, so the sizes of the baking trays used may be quite different. By setting the guide plate 6, when the horizontal conveying mechanism 2 transports baking trays of different sizes, the specific position of the baking tray can be leveled by the guide plate 6, which makes it easier for the clamping mechanism 4 to clamp the baking tray of the corresponding size, thereby improving the overall operation smoothness and reliability of the device.

[0058] In a possible implementation, the upright pole assembly 51 of the automatic stacking device includes a rotating shaft 511, a bearing 512, an upright pole portion 513 and a pull rod portion 514, wherein the bearing 512 is fixed to the frame 1, the rotating shaft 511 is mounted on the bearing 512, the pull rod portion 514 is connected to the rotating shaft 511, and the pull rod portion 514 is hinged to the upright pole portion 513;

[0059] The driving assembly 52 includes a push rod motor, which is fixed on the frame 1, and the piston rod of the push rod motor is hinged to the pull rod portion 514. Figure 4 , and combined with Figure 4 After starting the device, the rod portion 514 rotates under the drive of the push rod motor, thereby driving the vertical rod portion 513 to rotate around the rotation axis 511, so that the vertical rod portion 513 can be moved to the stacking cavity, forming a space on the stacking cavity that can accommodate and limit the baking trays. In this space, the stability of several stacked baking trays when moving up and down can be guaranteed, and the baking trays can be guaranteed not to overturn. When the number of stacked baking trays reaches the set value of the device, the vertical rod portion 513 is reset under the drive of the push rod motor, and the baking trays are released. Under the transmission of the horizontal conveying mechanism 2, the stacked baking trays can be sent to the next process.

[0060] In a possible implementation, the upright pole portion 513 of the automatic stacking device includes two first upright poles 5131 and two second upright poles 5132, wherein the two first upright poles 5131 are disposed at both ends of the rotating shaft 511, and the two second upright poles 5132 are located between the two first upright poles 5131;

[0061] The pull rod portion 514 includes a first pull rod 5141 and a second pull rod 5142. The first end of the first pull rod 5141 is connected to the rotating shaft 511. The second end of the first pull rod 5141 is hinged to the first vertical rod 5131. The piston rod of the push rod motor is hinged to the first vertical rod 5131.

[0062] The first end of the second pull rod 5142 is connected to the rotating shaft 511, and the second end of the second pull rod 5142 is hinged to the second vertical rod 5132. The length of the second pull rod 5142 is smaller than the first pull rod 5141, so that when the push rod motor drives the rotating shaft 511 to rotate, the second pull rod 5142 abuts against both sides of the frame device, and the first pull rod 5141 abuts against both ends of the frame device. The two ends of the frame device are the two ends of the frame device along the conveying direction of the horizontal conveying mechanism 2.

[0063] In order to improve the stability of the baking tray during the stacking process, a first pull rod 5141 and a second pull rod 5142 are provided, and the length of the first pull rod 5141 is greater than that of the second pull rod 5142. When driven by the push rod motor, the first vertical rod 5131 and the second vertical rod 5132 connected to the first pull rod 5141 and the second pull rod 5142 rotate at different distances around the rotating shaft 511, so that the four sides of the baking tray can be fixed, thereby further improving the reliability of the device during operation.

[0064] Compared with the prior art, the utility model provides an automatic stacking device, in which the combined operation of the vertical lifting mechanism 3 and the clamping mechanism 4 efficiently realizes the function of stacking multiple frame appliances up and down, improves the degree of automation, and the limiting mechanism 5 provided can improve the stability and reliability during the stacking process, and has high stacking efficiency, ensuring food hygiene and safety.

Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
