In order to improve the feeding efficiency, most of the feeding in industrial production is realized by mechanical equipment. The existing feeding devices pick up products by means of suction or clamping. However, the above methods are not suitable for the feeding of soft sheet-like products. Because, when sucking soft sheet-like breathable products, they are too soft to form a relatively flat surface, and the air permeability of the products causes the suction cups to not suck firmly; when grasping soft sheet-like products, they are prone to wrinkling, and it is impossible to control only one product to be grasped at a time. Therefore, in view of the above problems, it is necessary to propose a further solution. Summary of the Invention

[0020] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments recorded in the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0022] Figure 2 is Figure 1 Enlarged three-dimensional view of the feeding device in the above;

[0023] Figure 3 is Figure 1 Internal structure schematic view of the feeding device in the above. Specific embodiments

[0024] The present invention will be described in detail below in conjunction with various embodiments. However, it should be noted that these embodiments are not limitations on the present invention. Any equivalent transformation or substitution in terms of function, method, or structure made by those of ordinary skill in the art according to these embodiments shall fall within the protection scope of the present invention.

[0025] As Figures 1-3 shown, the present invention provides a grasping and feeding device, which is applicable to the feeding of soft sheet-like products. The grasping and feeding device includes: a feeding device 1, a driving device 2, and a feeding station 3. The driving device 2 drives the feeding device 1 to pick up soft sheet-like products and transfer them to the feeding station 3 to complete the feeding.

[0026] As Figure 2 shown, the feeding device 1 includes: a housing 11, a grasping mechanism 12, and a driving mechanism 13.

[0027] Specifically, the grasping mechanism 12 includes: an unwinding roller 121, a guide roller assembly 122, and a winding roller 123.

[0028] Among them, a tape coil can be sleeved on the unwinding roller 121. When pulling out the tape on the tape coil, the unwinding roller 121 performs a synchronous axial pivoting action.

[0029] The guide roller assembly 122 is used to tension the pulled-out tape to form a sticky grasping surface capable of picking up products. Specifically, one guide roller assembly 122 is distributed on one side of the unwinding roller 121, and the other guide roller assembly 122 is distributed on the other side of the winding roller 123. Any one of the guide roller assemblies 122 includes: a first guide roller 1221 and a second guide roller 1222. The first guide roller 1221 and the second guide roller 1222 are arranged vertically offset, which is beneficial to the tensioning of the pulled-out tape. Thus, after the tape passes through one guide roller assembly 122 and the other guide roller assembly 122 in sequence, the tape in a tensioned state between the two guide roller assemblies 122 forms the sticky grasping surface.

[0030] In one embodiment, any one of the guide roller assemblies 122 further includes a bracket 1223, and the bracket 1223 is fixed to the housing 11. The first guide roller 1221 and the second guide roller 1222 are pivotally arranged on the bracket 1223. Since the first guide roller 1221 and the second guide roller 1222 are arranged in an up-and-down offset manner, the bracket 1223 is generally a T-shaped bracket 1223. The bracket 1223 pivotally connecting the first guide roller 1221 and the second guide roller 1222 can be provided separately or integrally.

[0031] In addition, in order to achieve deviation correction, in the guide roller assembly 122, on both sides of any one of the guide rollers, there are provided tape limiting baffles 1224 located on the bracket 1223. The size of the tape limiting baffle 1224 is larger than the diameter of the guide roller, and it integrally protrudes from the bracket 1223, and the tape is limited between the tape limiting baffles 1224 on both sides.

[0032] The winding roller 123 axially pivots actively to realize the winding of the tape. Thus, when grasping a product, a part of the tape is first pulled out to form the sticky grasping surface. The sticky grasping surface picks up the product through the sticky effect and turns the product to the loading station 3. Then, the winding roller 123 operates to wind up a section of the sticky grasping surface that has picked up the product and provides a new sticky grasping surface with better stickiness to continue picking up the product.

[0033] As Figure 3 shown, the driving mechanism 13 is used to realize the active axial pivoting of the winding roller 123. In one embodiment, the driving mechanism 13 includes: a motor 131, a driving gear 132, and a transmission gear 133. Among them, the driving gear 132 and the transmission gear 133 are received inside the housing 11. The driving gear 132 is sleeved on the output shaft of the motor 131, the transmission gear 133 is sleeved on one end of the winding roller 123, and the driving gear 132 meshes with the transmission gear 133. Thus, when the motor 131 works, it drives the winding roller 123 to operate through the transmission of the gears, and the winding roller 123 drives the unwinding roller 121 to perform synchronous operation through the tape to realize the pulling out of the tape.

[0034] In one embodiment, in order to provide a larger sticky grasping surface and ensure the stability of grasping, there are two grasping mechanisms 12, and the two grasping mechanisms 12 are distributed on both sides of the lower end of the housing 11.

[0035] In one embodiment, the loading device 1 can be configured as two. This allows the loading device 1 to achieve dual-station loading, improving loading efficiency. The two loading devices 1 are distributed on the left and right sides and driven synchronously or asynchronously by the drive device 2. When the two drive devices 2 load synchronously, the two drive devices 2 are integrated on a base plate 14, which is in transmission connection with the drive devices 2. In this case, the four corners of the base plate 14 are provided with connecting posts that connect to the drive devices 2.

[0036] The driving device 2 drives the loading device 1 to move in the X direction and the Z direction.

[0037] Specifically, the driving device 2 includes a horizontal driving mechanism 21 for realizing X-direction driving and a lifting driving mechanism 22 for realizing Z-direction driving.

[0038] The horizontal driving mechanism 21 includes a linear motor 211 and a slide rail 212 , which are located on the same horizontal plane. The linear motor 211 and the slide rail 212 are arranged in parallel and along the X direction.

[0039] The lifting drive mechanism 22 includes: a cylinder 221, a guide column 222, and a fixed plate 223. The cylinder 221 is arranged on the fixed plate 223. One end of the fixed plate 223 is connected to the linear motor 211 for transmission, and the other end is slidably connected along the slide rail 212. The cylinder 221 is connected to the loading device 1 for transmission, and the loading device 1 moves up and down along the guide column 222.

[0040] Thus, when the loading device 1 picks up the product, the horizontal drive mechanism 21 is activated to drive the loading device 1 to move above the loading station 3. Then, the lifting drive mechanism 22 is activated to drive the loading device 1 to place the product at the corresponding position of the loading station 3.

[0041] The loading station 3 includes a loading platform 31, a positioning groove 32 provided on the loading platform 31, and a pressing assembly 33 distributed around the positioning groove 32. In one embodiment, the pressing assembly 33 is a pneumatic pressing block.

[0042] Thus, the lifting drive mechanism 22 is activated, driving the loading device 1 to place the product into the positioning groove 32 of the loading station 3, and then the pneumatic pressure block presses the edges of the product. At this time, the lifting drive mechanism 22 is activated, driving the loading device 1 to rise and leave the pressed product.

[0043] In summary, the grabbing and loading equipment of the present invention picks up products by means of sticky grabbing and transfers the products to the loading position, which overcomes the shortcomings of existing loading equipment and well realizes the loading of soft sheet products.
