Detailed Description

The invention provides a feeding device, which is further described in detail below by referring to the accompanying drawings and embodiments in order to make the purpose, technical scheme and effect of the invention clearer and clearer. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of the invention.

Herein, "front" is a direction indicated by an arrow in fig. 5, 6, 11, 12, 13, i.e., a transfer direction of the sheet, and "rear" is opposite to "front". The transverse direction is the left-right direction.

Referring to fig. 1 to 16, the present invention provides a feeding device, including a frame a, a sheet positioning device b disposed on the frame a, and a sheet transfer device c disposed downstream of the sheet positioning device b, where the sheet transfer device c includes a carriage c2 slidably disposed on the frame a, and a traction mechanism c3 for driving the carriage c2 to move back and forth, the carriage c2 is provided with a plurality of material supporting arms c4 extending in the front and back direction, and a constant pressure mechanism c5 for pressing a sheet against the material supporting arms c4, the carriage c2 is provided with a material ejecting roller c61 disposed upstream of the material supporting arms c4, and a jacking driving mechanism for driving the material ejecting roller c61 to move up and down, and the sheet positioning device b is used for adjusting the transverse position of the sheet. The traction mechanism c3, the constant pressure mechanism c5, the jacking driving mechanism and the plate positioning device b are electrically connected by a control system (such as a PLC control system).

The feeding device provided by the invention is matched with unwinding equipment to carry out full-automatic welding feeding, and the specific working process is as follows:

a sliding frame c2 in a plate material transfer device c is located at a position close to a plate material positioning device b in an initial state, the unreeling device unreels strip steel, so that the plate material firstly enters the plate material positioning device b, and when the position sensing component b9 senses that the plate material reaches a preset position, (1) the position sensing component b9 feeds back a signal to a control system, and the control system controls the plate material positioning device b to start to seek edges of the plate material; (2) the situation that a plate d is about to be transited from the plate positioning device b to the plate transferring device c is described, meanwhile, the control system controls the jacking driving mechanism to act, so that the jacking driving mechanism drives the jacking roller c61 to continuously perform reciprocating actions of ascending and descending within a set time, when the front end portion of the plate d passes through the jacking roller c61, the front end of the plate d abuts against the arc surface of the jacking roller c61, the plate d continues to advance under the action of the unreeling device, and under the guiding action of the arc surface of the jacking roller c61 and the action of elastic deformation of the front end of the plate d, the plate d is gradually unfolded and flattened above the jacking roller c61 from a downward bending state; in addition, under the action of continuous up-and-down reciprocating movement of the jacking roller c61, the front edge of the plate d swings up and down along with the jacking roller c61, and generally, after the plate is jacked up by the jacking roller c61, the plate d directly slides onto the top surface of the material supporting arm c4, so that the problem of shell clamping cannot occur; even if the front edge of the sheet metal is temporarily clamped at the rear end of the material supporting arm c4 and cannot continue to advance, the jacking roller c61 can quickly jack the sheet metal d upwards, so that the front edge of the sheet metal d smoothly goes over the top surface of the material supporting arm c4 and is pressed on the material supporting arm c4, and the problem of shell clamping is solved. (3) The control system controls the unreeling device to stop unreeling after a set time length, so that the head of the sheet material after the unreeling is stopped is supported by the material supporting arm c4, and the front end of the sheet material is supported by the auxiliary supporting mechanism c 7.

After the edge of the plate positioning device b is successfully found, the plate positioning device b adjusts the transverse position of the plate, so that the front end of the plate is aligned with the tail end of the plate in the front row. Then the plate is pressed tightly on the material supporting arm c4 by the constant pressure mechanism c5, on one hand, the plate can move forward along with the forward movement of the sliding frame, and the plate is prevented from moving in the moving process; on the other hand, in the welding process of the plate, the constant pressure mechanism c5 still compresses the plate, so that the plate is prevented from deviating.

Note that, in the initial state of the topping roller c61, the height of the topping roller c61 is flush with the height of the carrier arm c 4. After the jacking cylinder c62 drives the jacking roller c61 to complete the up-and-down reciprocating motion within a set time, the jacking cylinder c62 enables the jacking roller c61 to keep in a jacking state, namely the height of the jacking roller c61 is higher than that of the material supporting arm c4, through the arrangement, the height of a plate positioned between the plate positioning device b and the material supporting arm c4 can be improved to the maximum extent, and the phenomenon that the plate bends downwards due to gravity in the transferring process and the corner of the sliding frame c2 rubs to influence the product quality is avoided. When the plate is welded, the constant pressure mechanism c5 releases the plate, and the ejection cylinder c62 drives the ejection roller c61 to reset to the initial position. It should be understood that the control system controls the action duration of the jacking driving mechanism, and the control system can be implemented by setting the existing control program.

In practical application, the height of the material supporting roller B2 is slightly higher than the top surface of the material supporting square pipe B131, and the gap between the material supporting roller B2 and the groove wall of the U-shaped groove B133 is extremely narrow, so that the front edge of the plate material can smoothly fall on the top surface of the material supporting square pipe B131 after leaving the material supporting roller B2, and cannot be clamped into the gap between the material supporting roller B2 and the groove wall of the U-shaped groove B133 to form interference, so that the problem of shell clamping of the plate material in the positioning process is avoided.
