Description

Technical Field

[0001] The utility model relates to a palletizing device, in particular to a cake tray bottom palletizing device. Background Art

[0002] The cake tray is a base used to support the cake, and its shape mainly comes in two types: round and square. The structure of the cake tray includes base paper, foam board and cover paper. The size of the foam board is slightly smaller than the base paper. The foam board is located on the upper side of the base paper. The cover paper completely wraps the foam board and fits and fixes it to the edge of the base paper, making the cake tray look like a "dish" shape.

[0003] After the cake trays are produced, they need to be stacked and packaged in fixed quantities. Therefore, the conventional production process needs to include a palletizing process. The common palletizing process is done manually, but this will increase the labor cost of production. Therefore, the cake tray production industry needs to develop a device that can automatically palletize cake trays. Summary of the invention

[0004] The utility model provides a cake tray bottom stacking device, which solves the problem in the prior art that a large amount of labor costs are required for the stacking process.

[0005] The above technical problems of the utility model are mainly solved by the following technical solutions: A cake tray bottom stacking device, characterized in that it comprises: a support frame, the front and rear sides of which are respectively provided with a material dropping position and a stacking position;

[0006] The slide rails are horizontally fixed on the support frame and are distributed front and back;

[0007] A slide table is slidably mounted on the slide rail and is used to carry and transfer the cake tray;

[0008] A horizontal reciprocating mechanism is fixed on the support frame and can drive the slide to reciprocate along the slide rail between the blanking position and the stacking position;

[0009] A vertical reciprocating mechanism, fixed on the stacking position of the support frame and higher than the moving path of the slide;

[0010] A lifting platform is arranged at the output end of the vertical reciprocating mechanism, and a negative pressure device is arranged downward on the lifting platform;

[0011] A horizontal conveyor belt, whose conveying path passes through the stacking position and is lower than the moving path of the slide;

[0012] A material dropping guide assembly is fixed on the support frame and is located between the horizontal conveyor belt and the moving path of the slide. The interior of the material dropping guide assembly constrains a material dropping channel, the bottom of the material dropping channel faces the horizontal conveyor belt, and one side of the material dropping channel is open.

[0013] The operating principle of the utility model is as follows: the support frame is fixed on the production line for producing cake tray bottoms, ensuring that the drop position is right opposite to the drop point of the cake tray bottom production line. The production line will drop a single cake tray bottom onto the slide table each time. At this time, the horizontal reciprocating action mechanism can push the slide table to move along the slide rail to the stacking position, and then the vertical reciprocating action mechanism pushes the lifting platform down, so that the negative pressure device thereon abuts against the upper surface of the cake tray bottom. The negative pressure device is in a negative pressure state at this time, and the cake tray bottom is firmly adsorbed on the negative pressure device. Then the horizontal reciprocating action mechanism pulls the slide table to reset, the negative pressure device returns to normal pressure, and the vertical reciprocating action mechanism resets, and the cake tray bottom will fall into the drop channel below. Under the guiding action of the drop guide assembly, the cake tray bottom can fall on the horizontal conveyor belt according to a predetermined posture and position. At this time, the horizontal conveyor belt is in a stopped state. This cycle is followed until the number of cake tray bottom stacking in the drop channel reaches a preset number, and the horizontal conveyor belt will start to operate to transport the cake tray bottom in the drop channel out to enter the next packaging process.

[0014] Furthermore, baffles fixed relative to the support frame are symmetrically arranged on both sides of the moving path of the slide, and the baffles are divided into a guide segment and a positioning segment. The guide segment is inclined, and the guide segment is located in the transition zone between the blanking position and the stacking position, and the positioning segment is located in the stacking position. The contour formed by the two guide segments is funnel-shaped, and the spacing gradually decreases. The two positioning segments are parallel to each other, and the spacing is slightly larger than the width of the cake tray. In this way, during the movement of the slide, even if the position of the cake tray supported on it in the left and right directions is not correct, it will tend to be corrected under the guidance of the two guide segments.

[0015] Furthermore, a front limit plate protruding upward is provided on the front side of the slide, and the upper end of the front limit plate is bent outward; a rear limit baffle is also fixed on the support frame, and the rear limit baffle is located on the rear side of the baffle. One of the functions of the front limit plate is to push the cake tray bottom through the guidance of the two baffles, and then another function is to press the cake tray bottom against the rear limit baffle, and with the two positioning segments, the four directions of the cake tray bottom are all limited, so it can be ensured that the cake tray bottom can face the drop channel every time, and it can be ensured that it can fall into the drop channel smoothly.

[0016] Therefore, compared with the prior art, the utility model has the following characteristics: 1. The slide at the upper and lower loading position of the utility model can receive the cake trays from the cake tray production line, and the horizontal reciprocating mechanism can push the slide to move along the slide rail to the stacking position, and then the vertical reciprocating mechanism pushes the lifting platform down, so that the negative pressure device thereon abuts against and adsorbs the upper surface of the cake tray, and then the horizontal reciprocating mechanism pulls the slide to reset, the negative pressure device returns to normal pressure, and the vertical reciprocating mechanism resets, and the cake tray will fall into the loading channel below. Under the guidance of the loading guide assembly, the cake tray can fall on the stopped horizontal conveyor belt in a predetermined posture and position. This cycle is repeated until the number of cake tray stacking in the loading channel reaches the preset number, and the horizontal conveyor belt will start to operate to transport all the cake trays in the loading channel out, thereby realizing the automatic stacking function.

[0024] Example 1: See Figure 1 , Figure 2 and Figure 5, a cake tray palletizing device, used for palletizing square cake trays 10, comprising: a support frame 100, wherein a material drop position 101 and a palletizing position 102 are respectively provided at the front and rear sides thereof;

[0025] Two slide rails 110 are horizontally fixed on the support frame and distributed front and back, and a slider 120 is slidably matched on the slide rails;

[0026] The slide 130 is fixedly mounted on the two sliders, and the upper surface of the slide is used to carry and transfer the cake tray;

[0027] The horizontal reciprocating mechanism 200 is fixed on the support frame and can drive the slide to move back and forth between the blanking position and the stacking position along the slide rail, and is specifically a long-stroke single-axis cylinder;

[0028] A vertical reciprocating mechanism 300 is fixed on the stacking position of the support frame and is higher than the moving path of the slide, specifically a double-axis cylinder;

[0029] See Figure 4 , a lifting platform 310 is provided at the output end of the vertical reciprocating action mechanism, and a negative pressure device 320 is provided on the lifting platform, which is arranged downward, specifically two vacuum suction cups, and the air path control of the vacuum suction cups belongs to the skills possessed by those skilled in the art, so it will not be described in detail here;

[0030] A horizontal conveyor belt 400, whose conveying path passes through the palletizing position and is lower than the moving path of the slide;

[0031] The material drop guide assembly 500 is fixed on the support frame and is between the horizontal conveyor belt and the moving path of the slide. A material drop channel 510 is constrained inside the material drop guide assembly. The bottom of the material drop channel faces the horizontal conveyor belt. One side of the material drop channel is open. The material drop guide assembly is composed of a plurality of vertically fixed guide posts 501. The head ends of the guide posts are chamfered.

[0032] It also includes an electrical control system, which is a skill possessed by those skilled in the art and will not be described in detail here.

[0033] The operating principle of this embodiment is as follows: the support frame is fixed to the production line for producing cake trays to ensure that the drop position is opposite to the drop point of the cake tray production line. The production line will drop a single cake tray onto the slide each time. At this time, the horizontal reciprocating action mechanism can push the slide to move along the slide rail to the stacking position, and then the vertical reciprocating action mechanism pushes the lifting platform down, so that the negative pressure device thereon abuts against the upper surface of the cake tray. The negative pressure device is in a negative pressure state at this time, and the cake tray is firmly adsorbed on the negative pressure device. Then the horizontal reciprocating action mechanism pulls the slide to reset, the negative pressure device returns to normal pressure, and the vertical reciprocating action mechanism resets, and the cake tray will fall into the drop channel below. Under the guidance of the drop guide assembly, the cake tray can fall on the horizontal conveyor belt in a predetermined posture and position. At this time, the horizontal conveyor belt is in a stopped state. This cycle is followed until the number of cake tray stacking in the drop channel reaches a preset number, and the horizontal conveyor belt will start to operate to transport the cake tray in the drop channel out to enter the next packaging process. The number of cake trays stacked can be measured by the PLC built-in counting program, or by installing sensors on the support frame to detect the real-time height of the stacking.

[0034] See Figure 1 The moving path of the slide is symmetrically provided with baffles 600 fixed relative to the support frame on both sides. The baffles are divided into a guide segment 610 and a positioning segment 620. The guide segment is inclined. The guide segment is located in the transition zone between the blanking position and the stacking position, and the positioning segment is located in the stacking position. The contour formed by the two guide segments is funnel-shaped, and the spacing is gradually reduced. The two positioning segments are parallel to each other, and the spacing is slightly larger than the width of the cake tray. In this way, during the movement of the slide, even if the cake tray supported on it is not in the right position in the left and right directions, it will tend to be corrected under the guidance of the two guide segments.

[0035] See Figure 1 and Figure 3 The front side of the slide is provided with a front limit plate 140 protruding upward, and the upper end of the front limit plate is bent outward; the support frame is also fixed with a rear limit baffle 150, which is located at the rear side of the baffle. One of the functions of the front limit plate is to push the cake tray bottom through the guidance of the two baffles, and then the other function is to press the cake tray bottom against the rear limit baffle, and with the two positioning segments, the four directions of the cake tray bottom are all limited, so it can be ensured that the cake tray bottom can face the drop channel every time, and it can be ensured that it can fall into the drop channel smoothly.

[0036] The horizontal reciprocating mechanism and the vertical reciprocating mechanism in this embodiment can also be replaced by existing common reciprocating mechanisms such as electric cylinders, servo slides, crank connecting rods, motor synchronous belts, etc.

[0037] It is obvious to those skilled in the art that the utility model can be changed in many ways, and such changes are not considered to be out of the scope of the utility model. All such modifications obvious to those skilled in the art will be included in the scope of the claims.
