Description

Technical Field

[0001] The present invention belongs to the technical field of sheet separators, and in particular relates to a sheet separation module that utilizes damping for precise sheet separation. Background Art

[0002] As the name suggests, a spreader is used to spread sheets; it is widely used in the field of machinery.

[0003] At present, the most widely used devices on the market are magnetic sheet separators, which use the principle of magnetic isotropy of iron sheets to achieve sheet separation and grabbing. However, this type of device can only operate on sheets made of magnetic iron materials. Now many fields no longer use bulky iron sheets, but use non-magnetic sheets such as aluminum sheets or stainless steel sheets. The previously mentioned sheet separators that use the magnetic pole principle to complete the sheet separation operation are not very easy to operate. Since the sheets are tightly adsorbed and there is no gap, two or more sheets will be grabbed together. Since stamping uses large-tonnage punching machines and high-precision molds, if two or more sheets of material are placed in the mold for stamping, the mold and machine tools will be damaged, which will cause huge losses. It also affects the work progress and the quality and efficiency of product processing. Therefore, it is urgent to develop a device that can accurately separate sheets. Summary of the Invention

[0004] In order to solve the defects and shortcomings of the prior art, the purpose of the present invention is to provide a sheet separation module which has a reasonable structural design, is easy to operate and utilizes damping to accurately separate sheets.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: it includes a spreader, a damper, a photoelectric switch and a sheet metal position adjuster; the outer wall of one end of the spreader is provided with a rack plate, and a group of air knives are provided next to the rack plate; the side fixing plate 1 of the spreader is arranged on one side of the sheet metal position adjuster through a connecting plate; the other side of the sheet metal position adjuster is connected to the side fixing plate 2 of the damper through a connecting plate; the fixing seat of the damper is connected to the side fixing plate 2; the photoelectric switch is arranged on the outside of the fixing seat, and the photoelectric switch is electrically connected to the control system; the sheet metal position adjuster is arranged at the front end of the connecting plate.

[0006] Preferably, the end of the damper is a urea damping block, which is movably embedded in the fixing seat through a telescopic sleeve, and the telescopic sleeve is connected to the cylinder.

[0007] Preferably, the drive mechanism of the rack plate is connected to a control system.

[0008] Preferably, the air knife is composed of seven holes arranged in a vertical direction (the air knife holes are used as auxiliary blowing after sheet separation, which has a better effect).

[0009] Preferably, the tail of the sheet material position adjustment is connected to the connecting plate through a telescopic member, the telescopic member is inserted into the connecting plate, and the tail of the telescopic member is connected to the cylinder.

[0010] Preferably, the connecting plate is fixed to the mounting column by screws, and the spreader, damper and sheet metal position adjuster are fixedly arranged along the connecting plate in the Z axis, and the spreader, damper and sheet metal position adjuster can move independently in the X axis.

[0011] Preferably, the connecting plate is slidably arranged on the mounting column, and the spreader, damper and sheet metal position adjuster move up and down along the Z axis with the connecting plate, and the spreader, damper and sheet metal position adjuster can move independently along the X axis.

[0012] The process of the present invention is as follows:

[0013] 1. Adjust the position of the sheet material. The sheet material should be no higher than the second position of the air knife from top to bottom, and no lower than the fourth position of the air knife from top to bottom. The position adjustment is automatically adjusted by transmitting signals from the photoelectric switch to the control system.

[0014] 2. After the sheet position is adjusted, the sheet separation module supports the sheet stack.

[0015] 3. When the sheet separation starts, the damper is extended first to press the material stack, and then the air knife blows air into the gap to destroy the original vacuum between the sheets, and then the rack plate of the spreader is extended again to separate the sheets.

[0016] This working mode is similar to separating sheets with two hands; the damper is equivalent to one hand holding down the material stack, the spreader is equivalent to the other hand, and the rack plate is equivalent to the fingers. One part of the sheet is pressed, and the other part can easily and accurately "open" the gap between the two sheets. The air knife blows air into the gap, easily destroying the original vacuum, thereby achieving the effect of precise sheet separation.

[0017] The beneficial effects of the present invention are as follows: the use of damping clamping plate facilitates the separation of the sheet by the separator, so that the separator always keeps a single sheet of sheet separated; it solves the problem that the separators on the market easily separate multiple sheets, and improves the success rate and accuracy of single sheet separation of the sheet; it has a wide range of applications and is not limited by the material of the sheet, avoiding various disadvantages existing in the existing technology and greatly improving work efficiency.

DETAILED DESCRIPTION

[0024] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention is described below using specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0025] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, the accompanying drawings only show structures and / or processing steps closely related to the solutions according to the present invention, while other details that are not closely related to the present invention are omitted.

[0026] See Figures 1-4 As shown, this specific embodiment adopts the following technical solution: it includes a spreader (the spreader adopts the spreader structure of patent number: ZL201420641393.X) 1, a damper 2, a photoelectric switch 3 and a sheet position adjuster 4; the outer wall of one end of the spreader 1 is provided with a rack plate 11, and a group of air knives 12 are provided next to the rack plate 11; the side fixing plate 13 of the spreader 1 is arranged on one side of the sheet position adjuster 4 through the connecting plate 5; the other side of the sheet position adjuster 4 is connected to the side fixing plate 21 of the damper 2 through the connecting plate 5; the fixing seat 22 of the damper 2 is connected to the side fixing plate 21; the photoelectric switch 3 is arranged on the outside of the fixing seat 22, and the photoelectric switch 3 is electrically connected to the control system (for controlling the relative height of the sheet and the spreader module); the sheet position adjuster 4 is arranged at the front end of the connecting plate 5.

[0027] The end of the damper 2 is a PU damping block 24 , which is movably embedded in the fixing seat 22 through a telescopic sleeve 23 , and the telescopic sleeve 23 is connected to the cylinder.

[0028] Furthermore, the driving mechanism of the rack plate 11 is connected to a control system.

[0029] Furthermore, the air knife 12 is composed of seven holes arranged in a vertical direction (the air knife holes serve as auxiliary air blowing after sheet separation, and have a better effect).

[0030] In addition, the tail of the sheet metal position adjuster 4 is connected to the connecting plate 5 via a telescopic member. The telescopic member is inserted into the connecting plate 5, and the tail of the telescopic member is connected to the cylinder. The position adjuster 4 is a commonly used position adjuster in the prior art. The sheet metal position adjuster is used to adjust the uniformity of the sheet metal when the edge of the sheet metal is uneven.

[0031] Example 1:

[0032] In this specific embodiment, the connecting plate 5 is fixed to the mounting column A by screws, and the spreader 1, damper 2 and sheet material position adjuster 4 are fixed in the Z-axis along with the connecting plate 5 (the spreader module is fixed, and the sheet material is automatically lifted to the specified position as needed), and the spreader 1, damper 2 and sheet material position adjuster 4 can move independently in the X-axis direction.

[0033] The process of sheet separation in this specific implementation method is as follows:

[0034] S1. Adjust the position of the sheet material so that the sheet material is not higher than the second position of the air knife 12 from the top to the bottom, and not lower than the fourth position of the air knife 12 from the top to the bottom. The position adjustment is automatically adjusted by transmitting a signal from the photoelectric switch 3 to the control system;

[0035] S2. After the sheet position is adjusted, the sheet separation module supports the sheet stack;

[0036] S3, when the sheet separation starts, the damper 2 is extended first to press the material stack, and then the air knife 12 blows air into the gap, breaking the original vacuum between the sheets, and the rack plate 11 of the separator 1 is extended again to separate the sheets;

[0037] S4, the sheet material decreases as each sheet is taken away. When it reaches the lower limit, the sheet material as a whole rises.

[0038] S5. After the sheet material reaches the specified height, repeat the above steps and cycle continuously.

[0039] This working mode is similar to separating sheets with two hands; the damper 2 is equivalent to one hand holding down the stack of materials, the spreader 1 is equivalent to the other hand, and the rack plate 11 is equivalent to the finger. One end of the sheet is pressed, and the other end can easily and accurately "open" the gap between the two sheets. The air knife blows air into the gap, easily destroying the original vacuum, thereby achieving the effect of precise sheet separation.

[0040] The sheet separation modules are arranged on both sides of the sheet material. The damper 2 is used to press the sheet material at the same end of both sides of the sheet material, and the sheet separation device 1 is used to separate the sheet material at the other end of both sides of the sheet material. Such sheet separation modules are operated in coordination with the same side and in an array. When operating large sheets, several dampers 2 can work together to improve the stability of the arrangement, and several sheet separation devices 1 can be operated at the same time to improve the accuracy of sheet separation.

[0041] Example 2:

[0042] In this specific embodiment, the connecting plate 5 is slidably set on the mounting column A, and the spreader 1, damper 2 and sheet material position adjuster 4 move up and down along the Z axis with the connecting plate 5 (the sheet material is fixed, and the spreader module is lowered to the specified position as needed), and the spreader 1, damper 2 and sheet material position adjuster 4 can move independently in the X axis direction.

[0043] The process of sheet separation in this specific implementation method is as follows:

[0044] N1. Adjust the position of the sheet material so that the sheet material is not higher than the second position of the air knife 12 from the top to the bottom, and not lower than the fourth position of the air knife 12 from the top to the bottom. The position adjustment is automatically adjusted by the photoelectric switch 3 transmitting a signal to the control system;

[0045] N2. After the sheet position is adjusted, the sheet separation module supports the sheet stack;

[0046] N3. When the sheet separation starts, the damper 2 is extended first to press the material stack, and then the air knife 12 blows air into the gap, breaking the original vacuum between the sheets, and then the rack plate 11 of the separator 1 is extended again to separate the sheets;

[0047] N4, the sheet metal is lowered as it is taken away one by one. When it reaches the lower limit of the air knife 12, the connecting plate 5 drives the sheet separation module (separator 1, damper 2 and sheet metal position adjuster 4) to descend as a whole;

[0048] N5. After the sheet separation module reaches the specified height, repeat the above steps and cycle continuously.

[0049] This working mode is similar to separating sheets with two hands; the damper 2 is equivalent to one hand holding down the material stack, the spreader 1 is equivalent to the other hand, and the rack plate 11 is equivalent to the finger. One side of the sheet is pressed, and the other side can easily and accurately "open" the gap between the two sheets. The air knife blows air into the gap, easily destroying the original vacuum, thereby achieving the effect of precise sheet separation.

[0050] The sheet separation module is positioned around the sheet material, using a damper 2 at one end to press the sheet material, and then using a separator 1 at the other end to separate the sheets. This sheet separation module operates in a counter-part manner. An array of dampers 2 can be placed on one end of the sheet material, and a corresponding array of separators 1 can be placed on the other end to improve sheet separation accuracy.

[0051] The arrangement of the sheeting modules of the present invention can also be arbitrarily set according to the needs of the sheet material. For example, for some special sheet materials, the sheeting modules can cooperate with each other, and the sheeting device 1 and the damper 2 can be arranged separately.

[0052] This specific embodiment utilizes damping clamping plate to facilitate sheet separation by the separator, so that the separator always keeps a single sheet of sheet separated; it solves the problem that separators on the market are prone to multiple sheet separation, and improves the success rate and accuracy of single sheet separation; it has a wide range of applications and is not limited by the material of the plate, avoiding various drawbacks existing in the existing technology and greatly improving work efficiency.

[0053] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.

[0054] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
