[0037] Venetian blinds come in a variety of different materials and sizes. For example, the blinds may include honeycomb blinds having multiple honeycomb cells, imitation wood blinds, or roller blinds. The windows to which the blinds are installed also come in a variety of sizes. Therefore, the blinds may need to be cut into specific lengths to be customized to fit the corresponding windows. Embodiments of the present disclosure relate to a blind cutting machine that is configured to be located within a retail store so that blinds can be customized to meet the needs of customers within the store. In some embodiments, this can avoid a waiting process in which a customer orders blinds online and waits for them to be cut and shipped to the customer or retail store for pickup. More specifically, embodiments of the present disclosure relate to improved safety features of a blind cutting machine to protect the operator, individuals near the blind cutting machine, and components of the blind cutting machine when used to trim blinds.

[0038] Figure 1 A shutter cutting machine 100 is shown according to some embodiments. The shutter cutting machine 100 may include a support structure 102. In the illustrated embodiment, the support structure 102 is a frame. It should be understood that the configuration of the support structure 102 may vary beyond the illustrated embodiment. The shutter cutting machine 100 includes an electronics module 104, a display screen 106, a platform 108, a cutting assembly 110, and a waste bin 112. It should be understood that the shutter cutting machine 100 may include one or more additional components.

[0039] In some embodiments, the electronics module 104 may include various circuits to connect the shutter cutting machine 100 to a power source.

[0040] In some embodiments, the display screen 106 may provide a user interface for an operator to interact with the shutter cutting machine 100 and provide specific settings related to shutter materials, lengths, combinations thereof, and the like.

[0041] In some embodiments, the platform 108 may receive the shutters to be cut.

[0042] In some embodiments, the cutting assembly 110 may include a housing 114 within which the cutting blade and other components are enclosed, thereby protecting the operator from any interaction with the cutting blade itself. In some embodiments, the cutting assembly 110 may include one or more safety devices, such as, but not limited to, a door and latch system (as described below). Figure 2-4 for a more detailed description).

[0043] In some embodiments, the shutter cutting machine 100 includes a waste bin 112 for collecting waste during the cutting process.

[0044] Figure 2 According to some embodiments, Figure 1 The cutting assembly 110 in Figure 2 , a portion of the housing 114 is removed so that the various components of the cutting assembly 110 can be seen.

[0045] The cutting assembly 110 may include a cutting blade 116 and a safety latch assembly 118. In some embodiments, the safety latch assembly 118 is offset from the cutting blade 116 so that the cutting blade 116 does not collide with the safety latch assembly 118 during a cutting operation. As shown, the offset of the safety latch assembly 118 is horizontal relative to the page.

[0046] In some embodiments, the security latch assembly 118 may include a first member 120 and a second member 122. The second member 122 may be secured to a third member 124. In some embodiments, the first member 120 may be referred to as a door, the second member 122 may be referred to as a latch, and the third member 124 may be referred to as a mounting block for the second member 122.

[0047] In some embodiments, the first member 120 can rotate about position R so that the first member 120 can move according to the height of the shutter being cut. This is because shutters of different materials may have different sizes. In some embodiments, the shutters (even if of similar materials) may have different sizes that the first member 120 can take into account. In operation, the first member 120 and the second member 122 can fix the shutter during the cutting operation. In some embodiments, the second member 122 can prevent the first member 120 from over-rotating.

[0048] In some embodiments, the blinds cutting machine 100 includes a guide 134. The guide 134 may also be referred to as a drop guide, a waste guide, a diverter, etc. The guide 134 may be, for example, a piece of angled material that is positioned and configured near the cutting blade 116 to direct the blinds cut material into a waste collection basket or waste collection area. In some embodiments, the guide 134 may extend downward from an area near the cutting blade 116, wherein the cut material is directed downward from the cutting blade 116 to a waste collection basket or waste collection area that is vertically lower than the cutting blade 116 and the guide 134 (e.g., closer to the floor on which the blinds cutting machine 100 is placed).

[0049] In some embodiments, the guide 134 can have a triangular prism shape. In some embodiments, the guide 134 can be a curved, angled piece of material that is connected to the shutter cutting machine 100 at a location close to the cutting blade 116. In some embodiments, the location of the guide 134 determines whether the guide 134 can successfully guide the cut material into a waste collection basket or waste collection area. For example, in some embodiments, if the guide 134 is spaced apart from the cutting blade 116, the cut material will pop out of the cutting blade 116 and will not be guided to the waste collection basket or waste collection area. In some embodiments, the gap between the guide 134 and the cutting blade 116 is minimized to as small as possible without causing the guide 134 to interfere with the rotation of the cutting blade 116.

[0050] According to some embodiments, Figure 3 Show Figure 1 100. In the illustrated embodiment, the first member 120 is in a position engaged with the second member 122. According to some embodiments, this may be referred to as a cutting position or cutting state. Although not shown, it should be understood that in the illustrated configuration, a blind may be loaded into the blind cutting machine 100 for cutting. In the cutting state, the first member 120 may prevent an operator or other individual from placing their hands (or other body parts), clothing, or other objects in the cutting area of ​​the blind cutting machine 100. In some embodiments, the first member 120 may also hold the blind in place for the cutting operation.

[0051] In the illustrated embodiment, the first member 120 abuts the second member 122, as shown at location 126. A portion 128 of the second member 122 extends above the first member 120 at location 126. In some embodiments, the first member 120 can hold the blinds to prevent vertical movement caused by the cutting process. In some embodiments, this can be a configuration in which the blind cutting machine 100 is configured to cut blinds with a smaller depth (e.g., imitation wood, honeycomb, roller blinds, or other types of blinds).

[0052] According to some embodiments, Figure 4 Shows Figure 1 1. A partial view of the cutting assembly 110 of FIG. 1. In the illustrated embodiment, the first member 120 is in a position engaged with the fourth member 130. According to some embodiments, this may be referred to as a cutting position or cutting state. In the illustrated embodiment, the first member 120 is rotated beyond the portion 128 because the size of the shutter being cut is large such that the second member 122 does not prevent the first member 120 from rotating further. In contrast, for shutters of this size (i.e., larger than Figure 3The fourth member 130 prevents the first member 120 from rotating further. In some embodiments, this may be the configuration of the blind cutting machine 100 for cutting imitation wood blinds.

[0053] Figure 5 According to some embodiments Figure 1 1 is a perspective elevation view of the cutting assembly 110 . Figure 5 Also visible in FIG. 1 is an actuator 132. In some embodiments, the actuator 132 is a linear actuator. In some embodiments, the actuator 132 is configured to move the third member 124 in the direction of the line L1-L2. The actuator 132 can move the second member 122 to a position such that the rotation of the first member 120 is not limited by the second member 122, but by the fourth member 130 ( Figure 4 ). Thus, the actuator 132 can control the limit of the first member 120 according to the desired shutter size, which size can be input into the display screen 106. In some embodiments, the actuator 132 may not be included. Instead, the operator can move the linear member in place of the actuator 132, and the cutting assembly 110 can include a clamp so that the operator can hold the third member 124 in place instead of the actuator 132 so that the operator can manually operate and adjust the shutter cutting machine 100.

[0054] Common Reference Figure 2-5 , the first member 120 and the corresponding rotational restriction by the second member 122 or the fourth member 130 prevents a hand from being inserted into the cutting assembly 110 during a cutting operation.

[0055] Figure 6 According to some embodiments, Figure 1 A perspective view of a Venetian blind cutting machine 100 is shown.

[0056] As shown, the guide 134 is adjacent to the cutting blade 116 ( Figure 6 1 ). A gap 136 is shown between the base 138 and the guide 134 of the blind cutting machine 100. In some embodiments, the gap 136 is sized to accommodate the cutting blade 116 during a cutting operation.

[0057] In some embodiments, the blinds cutting machine 100 includes a guide 134. The guide 134 may also be referred to as a drop guide, a waste guide, a diverter, etc. The guide 134 may be, for example, a piece of angled material that is positioned and configured near the cutting blade 116 to direct the cut material of the blinds into a waste collection area 140. In some embodiments, a waste collection basket may be disposed within the waste collection basket or waste collection area 140. In some embodiments, the guide 134 may extend downward from an area near the cutting blade 116, wherein the cut material is directed downward from the cutting blade 116 to a waste collection basket or waste collection area 140 that is vertically lower than the cutting blade 116 and the guide 134 (e.g., closer to the floor on which the blinds cutting machine 100 is placed).

[0058] In some embodiments, the guide 134 may have a triangular prism shape. In some embodiments, the guide 134 may be a curved, angled piece of material that is attached to the shutter cutting machine 100 at a location proximate to the cutting blade 116. It should be understood that these shapes are examples only. For example, in some embodiments, a planar sheet of material may be used as the guide 134. In some embodiments, the planar sheet of material may be curved to provide a curvature of the guide 134. In some embodiments, the position of the guide 134 determines whether the guide 134 can successfully guide the cut material into the waste collection basket or waste collection area 140. For example, in some embodiments, if the guide 134 is spaced apart from the cutting blade 116, the cut material will pop out of the cutting blade 116 and will not be guided to the waste collection basket or waste collection area 140. In some embodiments, the gap between the guide 134 and the cutting blade 116 is minimized to as small as possible without causing the guide 134 to interfere with the rotation of the cutting blade 116. In some embodiments, the guide 134 may have a thin edge adjacent to the cutting blade 116. In some embodiments, the thick edge can prevent the guide 134 from preventing waste from being directed into a waste collection basket or waste collection area. In some embodiments, the thickness of the guide 134 can vary, making the edge thinner, but the thickness of the guide 134 away from the edge can be greater than the thickness at the edge.

[0059] Figure 7 FIG. 1 is a schematic side view of a blind cutting machine 100 according to some embodiments. It is understood that the blind cutting machine 100 includes Figure 7 However, in order to simplify the schematic diagram of the blind cutting machine 100, these features have been removed.

[0060] In the illustrated embodiment, the shutter cutting machine 100 is shown with a shutter including a shutter portion 142 and a severed material portion 144. The severed material portion 144 is shown directed into a waste collection basket or waste collection area 140.

[0061] In the illustrated embodiment, the gap 136 is shown to be located between the base 138 and the guide 134. The cutting blade 116 is shown in the cutting position. As shown, the gap 146 between the cutting blade 116 and the guide 134 is minimized. Therefore, the schematic diagram shows that the cutting blade 116 and the guide 134 are almost in contact. It should be understood that the placement of the guide 134 is selected so that the guide 134 does not rub or otherwise contact the cutting blade 116.

[0062] As shown, the guide 134 can be a triangular prism. In some embodiments, the guide 134 can be a piece of material bent into a triangle (but not including all the sides of the triangular prism). In some embodiments, the slope of the guide surface 148 can be determined to ensure that the cut material portion 144 is guided into the waste collection basket or waste collection area 140. In some embodiments, if the slope is too steep, the guide 134 may not reduce the amount of the cut material portion 144 that can be ejected from the cutting blade 116. In some embodiments, a too gentle slope may interfere with the waste collection basket or waste collection area 140, or may not reduce the amount of the cut material portion 144 that ejected from the cutting blade 116.

[0063] In some embodiments, the length dimension of the guide 134 (i.e., into the page of the figure) can be the same or similar to the length dimension of the base 138. In some embodiments, the length dimension of the guide 134 can be less than the length dimension of the base 138, as long as the length dimension of the guide 134 at least covers the area where the cutting blade 116 is located when it is in the cutting position, so that the cut material portion 144 is guided by the guide 134 into the waste collection basket or waste collection area 140.
