[0002] The work clothes conveyor line is used to hang the work clothes on the hangers and convey them into the work clothes dryer and work clothes folding machine. The work clothes conveyor line generally has multiple manual feeding stations. Due to the inconsistent manual feeding speed, the hangers moving on the conveyor line will appear too aggregated or loose, which is not conducive to subsequent drying and folding. Summary of the invention

[0003] The purpose of the present invention is to provide a uniform distribution system for hangers on a work clothes conveyor line, in which blocking blocks are set to separate the work clothes, and through photoelectric sensors and calculations, only one work clothes is conveyed between adjacent blocking blocks on the conveyor line, thereby realizing the uniform distribution function of hangers.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A uniform distribution system for hangers on a work clothes conveyor line comprises a conveyor line, a photoelectric sensor and a plurality of workstations. A plurality of blocking blocks are evenly distributed on the conveyor line. The workstations send the hangers on the hangers from between adjacent blocking blocks into the conveyor line. The blocking blocks move with the conveyor line and pass through the photoelectric sensor positions. The photoelectric sensor counts by sensing the blocking blocks. Each time the blocking blocks are triggered, the count C of the control pulse counter is increased by 1. In the conveying direction, after each workstation releases the hanger step by step and sends it into the conveyor line, the different counting times of the hanger passing through each workstation behind are calculated, and the corresponding workstations are prohibited from releasing the hanger at the corresponding calculated time.

[0006] Furthermore, the stations are sequentially the first station, the second station, ... the Nth station, from the conveying direction of the conveyor line.

[0007] After the first station releases the hanger step by step and sends it to the conveyor line, the current count c1 is recorded, and the counting time of the hanger passing through the second station, the third station, ... the Nth station is calculated, and the corresponding stations are prohibited from releasing the hanger at the calculated corresponding counting time;

[0009] …

[0010] After the N-1 station releases the hanger step by step and sends it to the conveyor line, the current count c is recorded. N-1, and calculate the counting time of the hanger passing through the Nth station, prohibiting the Nth station from releasing the hanger at the calculated corresponding counting time.

[0011] Furthermore, the distances between adjacent blocking blocks are all L1.

[0012] Furthermore, the spacing distance between each workstation and the delivery intersection of the conveyor line is L2.

[0013] Furthermore, the number of pulses experienced by the hanger from one station to another adjacent station is i=L2 / L1.

[0014] Furthermore, after the first station releases the hanger step by step and sends it to the conveyor line, the current count c1=C is recorded, and the second station is prohibited from releasing the hanger when the pulse value = c1+i, the third station is prohibited from releasing the hanger when the pulse value = c1+2i... The Nth station is prohibited from releasing the hanger when the pulse value = c1+(N-1)i;

[0015] After the second station releases the hanger step by step and sends it to the conveyor line, the current count c2=C is recorded, and the third station is prohibited from releasing the hanger when the pulse value = c2+i, the fourth station is prohibited from releasing the hanger when the pulse value = c2+2i... The Nth station is prohibited from releasing the hanger when the pulse value = c2+(N-2)i;

[0016] …

[0017] After the N-1 station releases the hanger step by step and sends it to the conveyor line, the current count c is recorded. N-1 =C, prohibit the Nth station from pulse value =c N-1 +i releases the hanger.

[0018] Furthermore, i or the calculated pulse value is rounded up.

[0019] Furthermore, the photoelectric sensor is a slot-type photoelectric sensor.

[0020] The present application also discloses a control method for a uniform distribution system of clothes hangers on a work clothes conveyor line. After starting, the conveyor line drives the blocking blocks on it to convey forward. The distance between each blocking block is L1. The conveying speed of the conveyor line is fixed. At fixed intervals, the blocking block passes through the slot-type photoelectric sensor, so that the slot-type photoelectric sensor senses the blocking block. Each time it is triggered, the pulse counter count C increases by 1.

[0021] In each workstation, the hangers manually fed in enter the temporary storage area for temporary storage. After the hangers in the temporary storage area are released onto the conveyor line, they are transported forward along with the blocking blocks, pushing the hangers forward. The interval between each workstation and the intersection of the conveyor line is L2, i=L2 / L1;

[0022] After the first station releases the hanger step by step and sends it to the conveyor line, the current count c1=C is recorded. After the second station releases the hanger step by step and sends it to the conveyor line, the current count c2=C is recorded. After the N-1th station releases the hanger step by step and sends it to the conveyor line, the current count c is recorded. N-1 =C,

[0023] The second station is prohibited from releasing the hanger when the pulse value = c1+i, the third station is prohibited from releasing the hanger when the pulse value = c1+2i, c2+i... The Nth station is prohibited from releasing the hanger when the pulse value = c1+(N-1)i, c2+(N-2)i...c N-1 +i releases the hanger.

[0027] Figure 2 The present invention is a schematic diagram of a control method for a uniform distribution system of hangers on a work clothes conveyor line. DETAILED DESCRIPTION

[0028] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings, and this embodiment does not constitute a limitation of the present invention. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] A uniform distribution system for clothes hangers on a work clothes conveyor line, such as Figure 1 As shown, it includes a ring conveyor line, a photoelectric sensor and several workstations. Several blocking blocks are evenly distributed on the conveyor line. The workstations send the hangers on them from between the adjacent blocking blocks into the conveyor line. The blocking blocks move with the conveyor line and pass through the photoelectric sensor position. The photoelectric sensor is a slot-type photoelectric sensor, which is installed at the position where the blocking blocks pass on the conveyor line. It counts by sensing the blocking blocks. Each time it is triggered, the count C of the pulse counter controlled by the PLC controller is increased by 1;

[0030] In the conveying direction, after each station releases the hanger step by step and sends it to the conveying line, the different counting times of the hanger passing through each station behind are calculated, and the corresponding stations are prohibited from releasing the hanger at the calculated corresponding counting time.

[0031] like Figure 1 As shown, the stations are the first station, the second station, ... the Nth station (N is an integer greater than 1) in the conveying direction of the conveyor line.

[0032] After the first station releases the hanger step by step and sends it to the conveyor line, the current count c1 is recorded, and the counting time of the hanger passing through the second station, the third station, ... the Nth station is calculated, and the corresponding stations are prohibited from releasing the hanger at the calculated corresponding counting time;

[0033] After the second station releases the hanger step by step and sends it to the conveyor line, the current count c2 is recorded, and the counting time of the hanger passing through the third station, the fourth station, ... the Nth station is calculated, and the corresponding stations are prohibited from releasing the hanger at the calculated corresponding counting time;

[0034] …

[0035] After the N-1 station releases the hanger step by step and sends it to the conveyor line, the current count c is recorded. N-1 , and calculate the counting time of the hanger passing through the Nth station, prohibiting the Nth station from releasing the hanger at the calculated corresponding counting time.

[0036] Specifically, the distance between adjacent blocking blocks is L1, the distance between each workstation and the delivery intersection of the conveyor line is L2, and the number of pulses experienced by the hanger from one workstation to another adjacent workstation is i=L2 / L1.

[0037] After the first station releases the hanger step by step and sends it to the conveyor line, the current count c1=C is recorded (the count value C at this time is assigned to c1, the same below), and the second station is prohibited from releasing the hanger when the pulse value = c1+i, and the third station is prohibited from releasing the hanger when the pulse value = c1+2i... The Nth station is prohibited from releasing the hanger when the pulse value = c1+(N-1)i;

[0038] After the second station releases the hanger step by step and sends it to the conveyor line, the current count c2=C is recorded, and the third station is prohibited from releasing the hanger when the pulse value = c2+i, the fourth station is prohibited from releasing the hanger when the pulse value = c2+2i... The Nth station is prohibited from releasing the hanger when the pulse value = c2+(N-2)i;

[0039] …

[0040] After the N-1 station releases the hanger step by step and sends it to the conveyor line, the current count c is recorded. N-1 =C, prohibit the Nth station from pulse value =c N-1+i releases the hanger;

[0041] Here, i or the calculated pulse value may be rounded up, or other rounding methods may be used.

[0042] This embodiment also discloses a control method for a uniform distribution system of hangers on a work clothes conveyor line, comprising the following steps:

[0043] After starting, the circulating conveying motor on the conveyor line rotates, so that the conveyor line drives the blocking blocks installed on its chain to convey forward. The distance between each blocking block is L1, and the conveying speed of the conveyor line chain is fixed. At fixed intervals, the blocking block passes through the slot photoelectric sensor, so that the slot photoelectric sensor senses the blocking block. Each time it is triggered, the sensor increases the pulse counter count C by 1 through the PLC.

[0044] In each workstation, the manually fed hangers (along the track) enter the temporary storage area through gravity or conveying device for temporary storage. When the hanger induction proximity switch senses the hanger, the workstation stepping cylinder is activated to push the hanger forward. After the hanger in the temporary storage area is released and slides onto the conveyor line, it is transported forward with the blocking block to push the hanger forward. Two cylinders can be set in the temporary storage area, blocking the first and second hangers respectively, so as to control the temporary storage area to release hangers individually at the set time. It can also be replaced by other stepping release devices to control the release of hangers individually at the set time.

[0045] The interval distance between each workstation and the intersection of the conveyor line is L2. For the convenience of calculation, in this embodiment, i=L2 / L1 and rounded up;

[0046] After the first station releases the hanger step by step and sends it to the conveyor line, the current count c1=C is recorded. After the second station releases the hanger step by step and sends it to the conveyor line, the current count c2=C is recorded. After the N-1th station releases the hanger step by step and sends it to the conveyor line, the current count c is recorded. N-1 =C (assign the real-time count value C to c1, c2, etc.),

[0047] Correspondingly, the second station is prohibited from releasing the hanger when the pulse value = c1+i, the third station is prohibited from releasing the hanger when the pulse value = c1+2i, c2+i... The Nth station is prohibited from releasing the hanger when the pulse value = c1+(N-1)i, c2+(N-2)i...c N-1 +i releases the hanger;

[0048] For example, if there are only 4 workstations, they are workstations 1, 2, 3, and 4.

[0049] Whenever station 1 releases the hanger step by step, the current pulse value c1=C is recorded. Then when the pulse value C=c1+i, station 2 is not allowed to release the hanger step by step. When the pulse value C=c1+2i, station 3 is not allowed to release the hanger step by step. When the pulse value C=c1+3i, station 4 is not allowed to release the hanger step by step.

[0050] Whenever station 2 releases the hanger, the current pulse value c2=C is recorded. Then, when the pulse value C=c2+i, station 3 is not allowed to release the hanger, and when the pulse value C=c2+2i, station 4 is not allowed to release the hanger.

[0051] Whenever station 3 releases the hanger, the current pulse value c3=C is recorded. Then when the pulse value C=c3+i, station 4 is not allowed to release the hanger.

[0052] The above method can prevent the hangers released from the workstations from overlapping, thereby achieving the purpose of evenly distributing the hangers.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions should also be deemed to fall within the protection scope of the technical solution of the present invention.
