[0002] A chemical fertilizer production line is used for producing chemical fertilizers. During the automated production of chemical fertilizers, it is necessary to stack bagged chemical fertilizers. When stacking, usually a manipulator stacks the bagged chemical fertilizers onto a pallet, and the pallet is generally automatically conveyed to the chemical fertilizer stacking position through a pallet supply device. Some pallet supply devices in the current market are equipped with a pallet lifting device on the upper side of the conveyor. During operation, there are multiple pallets stacked on the conveyor cooperating with the pallet supply device. The pallet lifting device on the pallet supply device will lift all pallets except the bottommost pallet. After lifting, the conveyor will convey the bottommost pallet forward. After the forward movement of the bottommost pallet is completed, the lifting device will lower all pallets onto the conveyor, and the pallet supply is achieved by cycling in this way. The above-mentioned pallet supply device needs to be provided with a pallet lifting device, and the pallet lifting device also needs to complete processes such as clamping before lifting. Its structure is relatively complex and the cost is relatively high. Summary of the Invention

Specific implementation mode

[0021] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] A pallet supply device for a chemical fertilizer production line includes a horizontal conveyor 1 and a vertical conveyor 2 arranged perpendicular to the horizontal conveyor 1. The conveying directions of the horizontal conveyor 1 and the vertical conveyor 2 are perpendicular to each other. When the present utility model is applied, a plurality of pallet stacks can be placed at intervals on the horizontal conveyor 1 at the same time, and the horizontal conveyor 1 can sequentially convey the plurality of pallet stacks to the enclosure at the end of the horizontal conveyor 1.

[0023] A longitudinal pushing device is installed at the end of the horizontal conveyor 1. The longitudinal pushing device includes a first proximity switch 10, a longitudinal pushing cylinder 3, and an enclosure in a U shape. The enclosure includes a front enclosure board 4, a left enclosure board 5, and a rear enclosure board 6 connected in sequence. The front enclosure, the left enclosure, and the rear enclosure enclose a U-shaped structure. The enclosure can play a good limiting role for the pallet stack to prevent the pallet stack from tilting. The size of the enclosure can be reasonably designed according to the specifications of the pallet. The first proximity switch 10 is used to detect whether there is a pallet in the enclosure.

[0024] Front longitudinal pushing holes 7 and rear longitudinal pushing holes 8 are respectively opened at the bottoms of the front enclosure board 4 and the rear enclosure board 6. The heights of the front longitudinal pushing holes 7 and the rear longitudinal pushing holes 8 are greater than the height of one pallet and less than the height of two pallets, so that only one pallet can pass through the front longitudinal pushing hole 7 at a time. The lengths of the front longitudinal pushing holes 7 and the rear longitudinal pushing holes 8 are both greater than the length of the pallet.

[0025] The longitudinal pushing cylinder 3 is installed at the rear side of the rear enclosure board 6. A longitudinal pushing plate 9 that can sequentially pass through the front longitudinal pushing hole 7 and the rear longitudinal pushing hole 8 is installed on the piston rod of the longitudinal pushing cylinder 3. The vertical conveyor 2 is installed at the front side of the front enclosure board 4. The height of the longitudinal pushing plate 9 is slightly less than the heights of the front longitudinal pushing hole 7 and the rear longitudinal pushing hole 8. After the pallet stack moves into the enclosure, the longitudinal pushing cylinder 3 can push the bottommost pallet in the pallet stack through the longitudinal pushing plate 9, so that the bottommost pallet in the pallet stack passes through the front longitudinal pushing hole 7 and moves onto the vertical conveyor 2.

[0026] The first proximity switch 10 is installed on the lower side of the end of the transverse conveyor 1. When the transverse conveyor 1 is a roller conveyor, the first proximity switch 10 is arranged between two rollers. The detection direction of the first proximity switch 10 is vertically upward, and the installation position of the first proximity switch 10 is close to the left baffle. When the transverse conveyor 1 drives the pallet thereon to move into the enclosure and the pallet approaches the left baffle, the first proximity switch 10 will detect the pallet thereon. When the first proximity switch 10 detects that there is a pallet on its upper side, it will transmit an induction signal to the controller, and the controller controls the longitudinal push cylinder 3 to act. The longitudinal push cylinder 3 drives the longitudinal push plate 9 to move forward longitudinally, and the longitudinal push plate 9 drives the bottommost pallet to move forward through the front longitudinal push hole 7 onto the longitudinal conveyor 2.

[0027] The transverse conveyor 1 adopts a roller conveyor.

[0028] The longitudinal push plate 9 is in a square frame structure. By setting the longitudinal push plate 9 as a square frame structure in the present utility model, it can be avoided that the longitudinal push plate 9 completely moves out of the front longitudinal push hole 7, so that part of the longitudinal push plate 9 is always in the enclosure.

[0029] An alignment device is installed on one side of the longitudinal conveyor 2 close to the transverse conveyor 1. The alignment device includes alignment cylinders 11 respectively arranged on the left and right sides of the longitudinal conveyor 2, and alignment plates 12 are installed on the piston rods of the alignment cylinders 11. The longitudinal conveyor 2 adopts a roller conveyor. By setting the alignment device in the present utility model, the pallets entering the longitudinal conveyor 2 can be aligned so that the pallets are in the middle position of the longitudinal conveyor 2. When the alignment device performs the alignment action, only the cylinders on both sides need to drive the alignment plates 12 thereon to move inward simultaneously, and the two alignment plates 12 are on the upper side of the longitudinal conveyor 2.

[0030] Guide rods 13 are respectively fixedly installed on the front and rear sides of the bottom of the longitudinal conveyor 2. The two ends of the guide rods 13 are respectively fixedly connected to the frame of the longitudinal conveyor 2. Two sliding seats 14 are slidably installed on the two guide rods 13. The two guide rods 13 respectively pass through both sides of the sliding seats 14. Support rods 15 are respectively installed on the front and rear sides of the tops of the sliding seats 14. The support rods 15 pass through the longitudinal conveyor 2 and are connected to the alignment plates 12 on the same side. The piston rods of the alignment cylinders 11 are connected to the sliding seats 14 on the same side and drive the sliding seats 14 to reciprocate left and right along the guide rods 13. The alignment plates 12 are connected to the piston rods of the alignment cylinders 11 through the sliding seats 14. When the longitudinal conveyor 2 adopts a roller conveyor, the alignment device can adopt the above structure. The alignment plates 12 are fixedly connected to the sliding seats 14 through the two support rods 15. The alignment cylinders 11 are fixedly connected to the sliding seats 14 through the piston rods and drive the sliding seats 14 to reciprocate left and right along the two guide rods 13 to achieve the alignment action.

[0031] A second proximity switch 16 is installed at the bottom of the longitudinal conveyor 2, and the second proximity switch 16 is at the front end of the alignment plate 12. When the roller conveyor is adopted for the longitudinal conveyor 2 in the present utility model, the second proximity switch 16 can adopt the above installation position, that is, the second proximity switch 16 is installed at the bottom of the longitudinal conveyor 2 and between two rollers. By installing the second proximity switch 16 at the front end of the alignment plate 12, when the second proximity switch 16 senses that there is a pallet passing above, most of the structure of the pallet is between the two side alignment plates 12, and the second proximity switch 16 transmits the sensing signal to the controller, and the controller controls the simultaneous action of the two side alignment cylinders 11. After the piston rods on the alignment cylinders 11 extend, they immediately retract to complete the alignment action.

[0032] First guide plates 17 are respectively arranged on the front and rear sides of the transverse conveyor 1, and an inclined plate 18 inclined outward relative to the transverse conveyor 1 is arranged on the right side of the first guide plate 17, and the inclined plates 18 on the two first guide plates 17 form a flared opening. The first guide plate 17 is arranged on the right side of the enclosure. By arranging the two inclined plates 18 in a flared shape in the present utility model, the position of the slightly inclined pallet on the transverse conveyor 1 can be corrected so that the pallet can smoothly enter the enclosure.

[0033] A second guide plate 19 is arranged on the right side of the longitudinal conveyor 2 close to the transverse conveyor 1, and the second guide is inclined outward relative to the longitudinal conveyor 2. By arranging the second guide plate 19 inclined outward relative to the longitudinal conveyor 2 in the present utility model, the position of the slightly inclined pallet entering the longitudinal conveyor 2 can be corrected so that the pallet can smoothly enter between the two side alignment plates 12.
