Please refer to fig. 1 to 10. The plate processing apparatus includes a loading device 110, a processing device 130, a moving device 140, a frame 180, and a floor 170. The loading device 110, the processing device 130, and the frame 180 are attached to the upper surface of the floor 170. The mobile device 140 is connected to the frame 180. The loading device 110 may move the sheet material 120 to be processed to a later loading station. The moving device 140 may move the sheet material 120 to be processed in the first horizontal direction D1, the second horizontal direction D2 perpendicular to the first horizontal direction D1, and the vertical direction D3 to move the sheet material 120 located at the work station to the work station of the processing device 130 and to move the sheet material 120 located at the work station to the later discharging device 160.

The moving device 140 includes a fork 141, a rack and pinion structure, a motor, and a rail structure. As shown in fig. 4 to 10, the upper end of the frame 180 is provided with a first horizontal beam 153. The first horizontal beam 153 extends in a first horizontal direction D1. The moving means 140 comprises a second horizontal beam 154. The second horizontal beam 154 extends in a second horizontal direction D2.

As shown in fig. 5 and 6, the rack and pinion structure includes a first rack and pinion structure 145. The first rack and pinion structure 145 includes a first gear and a first rack. The motor includes a first motor 147. The first rack extends in a first horizontal direction D1. The first rack is connected to the first horizontal beam 153. The first motor 147 is connected to the second horizontal beam 154. An output shaft of the first motor 147 is connected to a first gear (not shown) to drive the first gear to rotate. The first gear is meshed with the first rack. The first motor 147 may thus drive the second horizontal beam 154 to move in the first horizontal direction D1.

The track structure includes a first track structure 146. The first rail structure 146 includes a first rail and a first slider. The first rail extends in a first horizontal direction D1. The first guide rail is connected to the first horizontal beam 153. The first slider is connected to the second horizontal beam 154. The first slider cooperates with the first guide rail. The second horizontal beam 154 is thus connected to the first horizontal beam 153 by means of the first slider and the first guide rail. The first rail structure 146 guides the movement of the second horizontal beam 154 in the first horizontal direction D1.

Referring to fig. 6 and 7, the displacement device 140 includes a transition flange piece 156. The rack and pinion structure includes a second rack and pinion structure 148. The second gear rack structure 148 includes a second gear (not shown) and a second rack. The motor includes a second motor 150. The second rack extends in a second horizontal direction D2. The second rack is connected to the second horizontal beam 154. The second electric machine 150 is connected to a transition flange piece 156. An output shaft of the second motor 150 is connected to the second gear to drive the second gear to rotate. The second gear is engaged with the second rack. Such that second motor 150 may drive transition flange piece 156 in a second horizontal direction D2.

The rail structure also includes a second rail structure 149. The second rail structure 149 includes a second rail and a second slider. The second rail extends in a second horizontal direction D2. The second rail is connected to a second horizontal beam 154. The second slider is connected to transition flange piece 156. The second slider cooperates with the second guide rail. The transition flange piece 156 is thus connected to the second horizontal beam 154 via the second slider and the second guide rail. Second track structure 149 guides the movement of transition flange piece 156 in a second horizontal direction D2.

Referring to fig. 6 to 9, the moving device 140 includes a vertical beam 155. The vertical beam 155 extends in the vertical direction D3. Vertical beams 155 are disposed through transition flange piece 156. The rack and pinion structure includes a third rack and pinion structure 151. The third rack and pinion structure 151 includes a third gear (not shown) and a third rack. The motor includes a third motor (not shown). The third rack extends in the vertical direction D3. The third rack is connected to the vertical beam 155. The third electric machine is connected to transition flange piece 156. An output shaft of the third motor is connected to the third gear to drive the third gear to rotate. The third gear is meshed with the third rack. So that the third motor can drive the vertical beam 155 to move in the vertical direction D3.

Preferably, the gear of the rack and pinion arrangement may be a bevel gear and the rack may be a bevel rack. Thereby, the accuracy of controlling the movement of the moving device 140 may be improved.

Preferably, the motor may be a servo motor. The operation of the motor is controlled by a servo. Thereby, the accuracy of controlling the movement of the moving device 140 can be further improved.

The track structure further comprises a third track structure 152. The third rail structure 152 includes a third rail and a third slider. The third rail extends in a vertical direction D3. The third rail is connected to the vertical beam 155. The third slider is connected to transition flange piece 156. The third slide block is matched with the third guide rail. The transition flange piece 156 is thus connected to the vertical beam 155 via the third slider and the third guide rail. The third rail structure 152 guides the movement of the vertical beam 155 in the vertical direction D3.

As shown in fig. 10, the fork 141 includes a bearing wall 142, a connecting arm 143, and a stopper wall 144. The bearing wall 142 and the stopper wall 144 extend in the first horizontal direction D1. In the first horizontal direction D1, the length of the bearing wall 142 is greater than the length of the limiting wall 144. The connecting arm 143 extends in the vertical direction D3. The bottom end of the connecting arm 143 is connected to one end of the bearing wall 142. The tip of the connecting arm 143 is connected to one end of the stopper wall 144. The bearing wall 142, the connecting arm 143 and the stopper wall 144 are configured in a C-shaped configuration. The sheet 120 may be placed in the C-shaped structure such that the retaining arms prevent the sheet 120 from falling out of the C-shaped structure.

In the present embodiment, at least one sheet (for example, any one of 1 to 6 sheets) of the plate material 120 can be moved at a time by the fork 141, and the processing efficiency is high.

Preferably, the free end of the stopper wall 144 is inclined obliquely upward. Thus, the opening of the C-shaped structure is configured as a flare. Thereby facilitating entry of the sheet material 120 into the opening of the C-shaped structure.

Preferably, the fork 141 includes a plurality of bearing walls 142, a plurality of limiting walls 144 and a plurality of connecting arms 143 connected in a one-to-one correspondence. Thus, the forks 141 include a plurality of C-shaped structures spaced apart in the second horizontal direction. Therefore, the bearing area of the pallet fork 141 on the plate 120 can be increased, and the plate 120 can be more stably supported.

The mobile device 140 further comprises a connection flange 157. The forks 141 are connected to the bottom ends of the vertical beams 155 by connection flanges 157. The attachment flange 157 is removably positioned to facilitate replacement of the forks 141.

The processing device 130 may be a water cutting processing apparatus. The processing device 130 includes a processing station. The processing device 130 may process the sheet material 120 located at the processing station into a predetermined shape.

Referring to fig. 1 to 4, the feeding device 110 includes a plate stacking platform 111, a feeding platform 112, and a horizontal pushing mechanism 113.

As shown in fig. 2, the sheet stacking platform 111 is used to stack sheets 120 to be processed. The sheet stacking platform 111 may be a hydraulic lift platform. The sheet stacking platform 111 is thus movable in the vertical direction D3 to adjust the height of the sheet 120 thereon relative to the horizontal pushing mechanism 113, thereby moving the portion of the sheet 120 thereon to the height of the following horizontal pushing portion 114, thus enabling the horizontal pushing portion 114 of the horizontal pushing mechanism 113 to move one or more sheets.

The moving stroke of the plate stacking platform 111 along the vertical direction D3 can be set as required. Preferably, the moving stroke of the plate stacking platform 111 in the vertical direction D3 may be set according to the number of the plates 120 required to move each time. For example, each time 6 sheets 120 need to be moved by the fork 141, the moving stroke of the sheet stacking platform 111 can be approximately the same as the sum of the thicknesses of the 6 sheets 120.

Preferably, the plate stacking platform 111 is movable in a horizontal direction. For example, the lower end of the sheet stacking platform 111 may be provided with a moving wheel (not shown) to move in a horizontal direction. Therefore, the position of the plate stacking platform 111 can be conveniently adjusted.

The horizontal pushing mechanism 113 includes a horizontal pushing frame, a horizontal pushing portion 114, and a cylinder 115. The pan carriage is attached to the upper surface of the floor 170. The horizontal push frame is located at one side of the sheet stacking platform 111 in the first horizontal direction D1. The cylinder block of the cylinder 115 is connected to the upper end of the horizontal push frame. The cylinder axis of the cylinder 115 is retractable in the first horizontal direction D1. The free end of the cylinder shaft of the cylinder 115 is connected to the flat push portion 114. Thus, at least part of the horizontal pushing mechanism 113 is located on the side of the sheet stacking platform 111 away from the loading platform 112. The horizontal pushing part 114 can be driven by the cylinder 115 to move in the first horizontal direction D1.

As shown in fig. 1, the loading platform 112 is located on a side of the plate stacking platform 111 away from the horizontal pushing mechanism 113. The loading device 110 is provided with a station to be loaded at the loading platform 112. The loading platform 112 has a translation mechanism (not shown). The translating structure may be configured as a timing belt. Portions of the timing belt move in a first horizontal direction D1.

As shown in fig. 3, a portion of the feeding platform 112 is recessed downward to form a feeding escape portion 116. In this embodiment, the feeding platform 112 includes a plurality of timing belts disposed at intervals along the second horizontal direction D2. The part of the feeding platform 112 between the adjacent timing belts is recessed downward to form a feeding escape part 116. The material loading bypass portion 116 extends through the entire material loading platform 112 along the first horizontal direction D1. Thus, the top of the material loading avoiding portion 116, and both ends thereof in the first horizontal direction D1 constitute a material loading opening. The feeding opening is arranged in a first horizontal direction D1.

When the fork 141 needs to move the sheet material 120 from the material loading station to the processing station, the bearing wall 142 of the fork 141 can move in the vertical direction or in the first horizontal direction D1 so that at least part of the bearing wall extends into the material loading avoiding portion 116. At this time, in the vertical direction D3, the upper surface of the support wall 142 is not higher than the upper surface of the material loading avoiding portion 116. I.e., the upper surface of the bearing wall 142 is not higher than the upper surface of the timing belt. At this time, the C-shaped structure of the fork 141 opens toward the horizontal pushing mechanism 113. The material supply bypass portion 116 is used to bypass the carrier wall 142.

Referring to fig. 1 and 2, when loading is required, the air cylinder 115 drives the flat push part 114 to move toward the loading platform 112, so that the flat push part 114 simultaneously pushes at least one sheet material 120 (the pushed sheet material 120 is located at the uppermost end of the whole of the stacked sheet materials 120) to move a portion of the sheet material 120 to the synchronous belt. The timing belt, now moving in the first horizontal direction D1, may move the sheet material 120 to a station where it is to be loaded. At this time, the fork 141 is moved by the moving device 140 so that at least a portion of the bearing wall 142 extends into the material loading avoiding portion 116. Such that the sheet material 120 enters the openings of the forks 141. The pallet fork 141 is moved upward to move the plate 120.

When loading is required, the fork 141 may be moved by the moving device 140 so that at least a portion of the supporting wall 142 extends into the loading avoiding portion 116. The sheet material 120 is then moved into the opening of the fork 141 by the flat push section 114 and timing belt.

When the horizontal pushing part 114 moves to its extreme position toward the loading platform 112, the air cylinder 115 drives the horizontal pushing part 114 to move away from the loading platform 112 to return to the original position. After the sheet material 120 leaves the sheet material stacking platform 111, the sheet material stacking platform 111 moves upward to raise the portion of the sheet material 120 currently located thereon to the flat push portion 114 to prepare for the next feeding.

As shown in fig. 1, the plate processing apparatus further includes a discharging device 160. The tripper device 160 is substantially identical in construction to the loading platform 112.

A portion of the discharge device 160 is recessed downward to form a discharge bypass 190. In the first horizontal direction D1, the discharge bypass 190 extends through the entire discharge device 160. Thus, the top of the discharge bypass 190, as well as its two ends in the first horizontal direction D1, constitute the discharge opening. The discharge opening is arranged in a first horizontal direction D1.

When the fork 141 needs to move the sheet material 120 from the processing station to the discharging device 160, the carrying wall 142 carrying the sheet material 120 can be moved in the vertical direction or in the first horizontal direction D1, so that at least part of the carrying wall 142 extends into the discharging bypass 190. At this time, in the vertical direction D3, the upper surface of the bearing wall 142 is not higher than the upper surface of the discharge avoidance portion 190. That is, the upper surface of the bearing wall 142 is not higher than the upper surface of the portion of the discharge device 160 constituting the discharge avoidance portion 190. At this time, the sheet 120 carried on the carrying wall 142 is placed on the discharging device 160. The discharge avoiding portion 190 is used for avoiding the carrier wall 142.

Further, the tripper device 160 does not include a translating structure. Furthermore, the discharge device 160 can be designed as a mobile carriage. The discharging device 160 is movable in the horizontal direction. Thus, the forks 141 can move the finished sheet 120 from the processing device 130 to the discharge device 160. The worker may move the sheet material 120 positioned thereon to the next station through the tripper device 160.

As shown in fig. 1, the horizontal pushing mechanism 113, the plate stacking platform 111, the feeding platform 112, the processing device 130 and the discharging device 160 are sequentially arranged along the first horizontal direction D1. Therefore, the plate processing equipment is simple in structure.

As shown in fig. 1, the plate processing apparatus includes at least two (e.g., two) feeding devices 110 spaced apart along the second horizontal direction D2. The processing device 130 has at least two (e.g., two) processing stations spaced apart along the second horizontal direction D2. The sheet processing apparatus includes at least two (e.g., two) discharge devices 160 spaced apart along the second horizontal direction D2. The forks 141 can be moved to all of the loading platforms 112, the processing stations of the processing device 130, and the discharge device 160. Therefore, the multi-station alternating or simultaneous working can be realized, and the working efficiency is improved.
